1.0 INTRODUCTION

This Project Operations Plan (POP) contains a Project Description and Background, Field Sampling Plan (FSP), and Quality Assurance Project Plan (QAPP) for the Former Manufactured Gas Plant (FMGP) site in Fairfield, Iowa '(Figure 1-1). This POP specifies data collection methods to be used during the field investigation phases of the Engineering Evaluation/Cost Analysis (EE/CA) and Remedial Investigation/Feasibility Study (RI/FS). An EE/CA work plan has been prepared that describes the procedures for evaluating options for the expedited removal of the potential sources of contamination. An RI/FS work plan has been prepared that describes procedures for evaluating potential soil and groundwater contamination from FMGP operations and for developing remedial alternatives. This POP covers the field investigation that will provide information for both the EE/CA and RI/FS.

Presented in the sections that follow are a brief site description, a discussion of authority for the work, and an explanation of the purpose and scope of the POP.

1.1 SUMMARY OF SITE The Iowa Electric Light and Power Company (IE) owns the site of a former manufactured gas plant on the south side of Fairfield, Iowa (Figure 1-2), a town of approximately 10,000 people. Between 1878 and 1950, coal was converted to low BTU gas at this plant and distributed to homes and businesses in the Fairfield area. The main contaminants normally associated with coal gasification processes are polynuclear aromatic hydrocarbons (PAHs), and benzene, toluene and xylene (BTX), which are found in the coal tar byproducts, and cyanide salts found in iron oxide wastes from the gas purification process.

In a 1986 study for IE, PAH and BTX compounds were found in both the soil and groundwater on the site. In a 1987 investigation for the EPA, PAH and BTX concentrations were confirmed immediately adjacent to the old FMGP; and concentrations of PAH, metals and low concentrations of .cyanide, were detected in soil samples collected in a drainage ditch south of the site.

1.2 AUTHORITY FOR WORK B&V Waste Management, Inc. (BVWMI) has been retained by IE to perform a site investigation at the Fairfield FMGP site. After the investigation is performed, results and observations will be summarized, and recommendations for subsequent source removal and overall remedial actions will be presented in EE/CA and RI/FS reports.

1.3 PURPOSE AND SCOPE OF THE PROJECT OPERATIONS PLAN The purpose of the POP is to provide a comprehensive document specifying data collection methods for the site investigation at the Fairfield FMGP site. The methods specified will assure that the data obtained during the investigation will satisfy the objectives and will be scientifically and legally defensible. Presented in Part I is a Project Description and Background. Part II presents the FSP, which describes techniques to be used for sample collection during the field investigation. Part III presents the QAPP which describes analytical methods and Quality Assurance/Quality Control (QA/QC) procedures to be used during the field investigation. Part IV includes appendices of supporting information. Part I Section 2 Rev. No. 0 Rev. Date 2/1/89 Page 1 of 7

2.0 PROJECT DESCRIPTION

Existing background data on the Fairfield FMGP site are summarized in this section. The primary sources of background data include investigation reports and memoranda by D. B. McDonald Research Associates, Tuthill, Inc., and Ecology and Environment. Additional sources include existing drawings of the plant, historical aerial photographs, and memoranda describing site visits by BVWMI personnel. A complete listing of all references and sources of information are presented in Appendix F.

2.1 SITE LOCATION AND DESCRIPTION Fairfield is located in central Jefferson County, Iowa, as shown in Figure 1-1. The Fairfield FMGP site, as shown in Figure 1-2, is located in the southwest quarter of the southeast quarter of Section 26, Township 72 North, Range 10 West of Jefferson County, Iowa. The exact address of the site is 107 South Seventh Street, Fairfield, Iowa. The FMGP site occupies about 1.3 acres (Figure 1-3) and is bounded on the north by Burlington Street; on the east by residential property and a former electric plant; on the south by an existing electrical substation, transformer storage area, and truck garage and salvage operation (Vintage Power Wagons); and on the west by Seventh Street, beyond which is a residential area. Use of the site as an operations and maintenance facility for IE's local gas and power distribution systems was discontinued in the fall of 1988.

2.2 SITE HISTORY The history of the Fairfield FMGP site is summarized here. For a more thorough discussion of the site history, see the RI/FS Work Plan.

Coal gasification operations began on this site in 1878. Gasification processes were performed in the fenced area, which surrounds the +

The coke was produced when the carbonized coal was cooled. The tar was also generated in this step, as well as in the purification steps. The coke was sold in Fairfield for home heating, and much of the tar was sold to farmers for preservation of fence posts. The tar was pumped from the separator (Figure 1-3) into rail cars for shipment to locations as far away as Eldora, Iowa. Excess tar was disposed of onsite (McDonald, April 1986).

In July 1937, the gas manufacturing process at the plant was changed from carbonized coal to carbureted water gas. The water gas process used a generator, boiler, carburetor, and superheater, as well as purifiers to produce a clean, higher grade BTU gas. The two by-products of the water gas process were coal tar and ammonia liquor. While the quality of the tar generated in the water gas process was lower than that produced in the carbonized coal process, it continued to be sold for fence post treatment. It has been reported that excess tar was also pumped to a nearby shallow ditch south of the plant or disposed in an earthen pit immediately south of the tar/water separator and west of the relief gas holder. Ammonia liquor was pumped into a pit under the original gas holder.

In 1950, the gas system in Fairfield was converted to natural gas. Operations at the manufactured gas plant were terminated, and the major pieces of equipment were removed. The interior of the building was modified for use as an operations facility for Iowa Electric (McDonald, April 1986). IE discontinued using the location as a base for natural gas and electrical distribution systems maintenance operations in the fall of 1988. Part I Section 2 Rev. No. 0 Rev. Date 2/1/89 Page 4 of 7

2.3 POTENTIAL CONTAMINANT SOURCES Based on previous investigations and a review of historic plant drawings, the following eight potential contaminant sources have been identified and discussed in the EE/CA and RI/FS work plans:

1. Coal tar spilled or disposed of along the railroad right-of-way.

2. A possible coal tar disposal pit near the relief gas holding base.

3. A pit under the original gas holder where miscellaneous wastes appear to have been dumped.

4. A tar separator (built in 1937) southwest of the operations building.

5. Potential contamination along Seventh Street due to road oil applications.

6. An existing hand dug well at the southeast corner of the operations building.

7. A drainage ditch south of the site, where coal tar and other wastes may have been disposed.

8. A tar separator (built in 1927) and a purifier pit under concrete slabs in the operations building.

The areas of these potential sources are shown in Figure 1-3.

2.4 SITE FEATURES A discussion of the site features is contained in the RI/FS Work Plan Site Features section, and includes descriptions of existing site features, meteorology, topography and drainage, geology and hydrogeology, and surrounding land use. Part I Section 2 Rev. No. 1 Rev. Date 3/3/89 Page 5 of 7

2.5 PREVIOUS INVESTIGATIONS The previous investigations at the Fairfield FMGP site are briefly summarized here. For a more thorough description, see Section 2.3 of the RI/FS Work Plan. To date, three separate investigations have been performed at the Fairfield FMGP site. The initial investigation was conducted in 1985 by D.B. McDonald Research Associates, an Iowa City, Iowa consulting firm, and resulted in a report in April 1986. The McDonald report concluded that the soil and shallow groundwater adjacent to the site had been contaminated but that neither the Fairfield municipal water supply, nor any of the private wells in the vicinity of the site had been contaminated. In addition, the McDonald report identified three potential routes of contaminations (1) surface application or spillage of coal tar along the railroad right of way; (2) disposal of coal tar in the drainage ditch south of the plant; (3) subsurface migration vertically along the foundation of the relief gas holding base.

In 1987, E&E/FIT conducted an investigation of the site under contract with EPA Region VII. The EE/FIT report confirmed the results of the McDonald report, with the additional finding of PAH, Metals, and Cyanide contamination in the surface soil from the ditch south of the plant.

Most recently, Tuthill, Inc., has been conducting a groundwater sampling program in private wells near the site and in wells that were installed during the McDonald and EE/FIT investigations. Analytical results of this monitoring program are included in Appendix A of the RI/FS Work Plan.

2.6 PRELIMINARY RISK ASSESSMENT A preliminary risk assessment has been prepared to identify potential risks to the public health and the environment posed by release of contaminants from the Fairfield FMGP site, establish goals and Part I Section 2 Rev. No. 1 Rev. Date 3/3/89 Page 6 of 7 objectives of site investigations, and to begin to define detection limits for analytical protocols. The preliminary risk assessment is summarized here. For a complete discussion of the preliminary risk assessment see the RI/FS Work Plan. The detection limits and analytical protocols will be developed further in the QAPP. This assessment is based primarily on a preliminary evaluation of the hazardous substances associated with FMGP sites in general and indicated to be in the environment by information contained in the McDonald and E&E/FIT reports.

Limited sampling has been performed to date in the areas within and surrounding the FMGP site. Based on a review of the sampling data, applicable literature, and the objectives of. the field investigation, the primary contaminants of concern associated with these sites are potentially carcinogenic polynuclear aromatic hydrocarbons (PAHs); the light aromatic compounds benzene, toluene, and xylene (BTXs); metals; and cyanide.

2.7 POTENTIAL MIGRATION PATHWAYS, RECEPTORS, AND ROUTES OF EXPOSURE Information from previous investigations and site history indicate that coal tar and other wastes generated in the manufactured gas process have been disposed of at the Fairfield FMGP site. As stated earlier, the contaminants of concern are PAHs, BTXs, metals, and cyanide. The potential migration pathways for these contaminants have been tentatively identified as groundwater and soil. Surface water and air are not considered to be potential migration pathways because the site is covered with crushed stone, and exposure of contaminants to these media is limited.

2.7.1 Groundwater Groundwater that is contaminated at the site could potentially migrate to local public or private wells, where it would be ingested by humans or livestock that use water from these wells. Groundwater has been Part I Section 2 Rev. No. 0 Rev. Date 2/1/89 Page 7 of 7 sampled in municipal water supplies and private wells to determine whether contaminants have migrated into these water supplies. The primary municipal water supplies consist of surface impoundments more than a mile northeast of the FMGP site. There is also a deep well (2155 ft.) which obtains water from the Jordan aquifer for back-up water supply. The McDonald report concluded that while low concentrations of xylene and chrysene were observed in both sources of the municipal water supply, it is unlikely that their presence is due to manufactured gas waste products (McDonald, April 1986, p. 44).

Private wells in the vicinity of the site appear to obtain groundwater from a sand layer at a depth of 21 to 35 feet below ground surface. If this sand layer is continuous, it could provide a route for migration of contaminants to shallow private wells in the area. During the 1987 investigation conducted by E&E/FIT, private wells sampled showed no evidence of contamination (E&E/FIT, May 1987, p. 7-1). However, recent results from the groundwater sampling program conducted by Tuthill Associates revealed slightly elevated levels of contaminants in several monitoring wells on site, as well as at least one private well off site (See Appendix A of the RI/FS Work Plan). This information indicates the need for further sampling.

2.7.2 Soil Soil is a potential migration pathway at the Fairfield FMGP site because contaminants present in the soil could potentially be transported to the groundwater. The extent to which the contaminants are transported through the soil depends on the chemical properties of the contaminant, the type of soil, and the amount of precipitation and infiltration. Previous investigations of the site have identified the soils to consist mainly of silty clays with numerous sand lenses and beds. The silty clays have low hydraulic conductivities (on the order of 2.5 x 10 7 cm/sec), but the existence of the sand lenses within 60 ft. of ground surface (McDonald, 1986, Figure 9) present a potential pathway for migration of subsurface contamination.

o Objectives of the field investigation.

o Rationale of field investigation sample locations and analyses.

o Detailed descriptions of sampling methodology, duplicates and blanks, analytical requirements, sample containers and preservation required for samples, and decontamination of sampling equipment.

o Procedures for handling field-derived wastes.

o Descriptions of sample documentation.

o Discussions of field organization and the field activities schedule. Part No. II Section No. 2 Rev. No. 0 Rev. Date: 2/1/89 Page 1 of 3

2.0 FIELD INVESTIGATION OBJECTIVES

The overall purpose of the field investigation is to identify and char­ acterize sources of contamination and to evaluate the extent and magnitude of soil and groundwater contamination, if present, from FMGP operations. Information obtained during the field investigation will be used in the development, evaluation, and recommendation of expedited removal actions for the EE/CA, and overall remedial response actions for the RI/FS. General objectives include the following:

o Identify source or sources of contamination.

o If contamination is present, determine whether migration from the FMGP site has occurred or could occur.

o Characterize hydrogeologic conditions of the site.

Specific field investigation objectives identified in the EE/CA work plan were:

o Identify coal tar or cyanide containing spent oxide contaminant sources on the plant site.

o Identify coal tar or cyanide containing spent oxide contaminant sources along railroad right-of-way between Burlington Avenue and Washington Street.

o Identify remnants or wastes of coal tar or cyanide containing spent oxide contaminant sources in the disposal pit west of the relief gas holding base. • Part No. II Section No. 2 Rev. No. 0 Rev. Date: 2/1/89 Page 2 Of 3

o Determine if PAH contamination exists on Seventh Street as a result of road oil application, and compare the results with PAH contamination from coal tar.

o Determine if contamination exists at the tar separator built about 1937.

Specific field investigation objectives identified in the RI/FS work plan were:

o Identify the extent and magnitude of contamination in the recently filled shallow ditch, located south of Washington Street on property owned by Vintage Power Wagons.

o Identify background soil and groundwater constituents.

o Identify the magnitude and extent of groundwater contamination.

o Identify physical characteristics of contaminated or threatened aquifer(s).

o Determine if any PAH or BTX contamination now exists in the creek south of the site.

o Develop additional data for evaluating the water quality in residential wells west of the site.

o Identify contaminant pathways and receptors and whether receptors are at risk due to specific contaminants.

These specific EE/CA and RI/FS objectives are applicable to this FSP with one clarification. PAH or BTX contamination may now exist in the creek south of the site due to a headwall recently constructed from • Part No. II Section No. 2 Rev. No. 0 Rev. Date: 2/1/89 Page 3 of 3 creosoted timber. Therefore, no sampling will be performed in this stream. Samples that E&E/FIT took from this stream showed no evidence of contamination in 1987.

To ensure the usefulness of the data, data quality objectives have been established, as presented in the RI/FS work plan. This FSP and the QAPP (Part III) were developed to satisfy the data quality objectives. Part No. II Section No. 3 Rev. No. 0 Rev. Date: 2/1/89 Page 1 of 25

3.0 FIELD INVESTIGATION RATIONALE

The EE/CA and RI/FS work plans define the conceptual scope of work required to evaluate soil and groundwater contamination from FMGP operations. The field investigation described below has been designed to incorporate this conceptual scope from both work plans. A summary of the data gaps and the investigation methods required for obtaining the information are presented in Table II-l.

3.1 SAMPLE LOCATIONS

Repeated below are the potential source or sources of contamination identified in the EE/CA and RI/FS work plans. These items are also listed in Part I, Section 2.3 of this POP and shown on Figure 1-3.

o Coal tar spilled or disposed of along the railroad right-of-way.

o A possible coal tar disposal pit west of and adjacent to the 30,000 cf gas holder foundation (relief gas holding base).

o A pit under the original gas holder where miscellaneous wastes appear to have been dumped.

o A tar separator (built in 1937) southwest of the operations building.

o Potential contamination along Seventh Street due to road oil applications. Part No. II Section No. 3 Rev. No. 0 Part No. 1^. Section No. 3 Rev. No. 0 Rev. Date: 2/1/89 Page 3 of 25

o An existing well at the southwest corner of the operations building.

o A drainage ditch south of the site, where coal tar and other wastes may have been disposed.

o A tar separator (built in 1927) and a purifier pit under concrete slabs in the operations building.

The first seven of these potential contaminant sources will be evaluated based on samples obtained directly from the location of the potential source. Groundwater data obtained during the field investigation will be evaluated to determine if exploratory drilling through the floor slab in the operations building is warranted to discover whether the purifier pit or 1927 tar separator or other voids containing contaminants exist and are releasing contaminants to the groundwater.

The locations of samples to be obtained for the EE/CA are shown on Figure II-l. The locations of samples to be obtained for the RI/FS are shown on Figure II-2. Descriptions of the sampling locations from the EE/CA and RI/FS work plan are repeated in the subsections that follow.

3.1.1 Railroad Right-of-Wav Investigation Borings and surface soil samples collected during the McDonald and EPA investigations along the abandoned railroad right-of-way indicate that the soil and groundwater along the right-of-way have been contaminated. Boring FI-1 (total depth of 6.5 feet) by McDonald encountered fill and a tar-like material, and a metallic sheen was noted on the soil and groundwater. Chemical analyses on both soil and groundwater samples from Boring FI-1 indicate the presence of contaminants. The presence of fill and tar-like -h

Date: 2/1/89 Page 6 of 25 material to a depth of 6.5 feet in boring FI-1 indicates that there may be pits along the railroad right-of-way that were backfilled and are potential sources of contaminants. To check for the presence of backfilled pits along the railroad right-of-way, borings B-20 through B-27 will be drilled. Each boring will be drilled by hollow stem augers through any fill that may be present and five feet into the native soil located below the fill. Continuous split barrel or continuous tube samples will be obtained to the full depth in each boring. The estimated total depth of each boring is 15 feet.

If field screening identifies contamination in a boring, two samples will be submitted: one contaminated, and one from the bottom of the boring. If no contamination is detected, one sample will be submitted to represent, with the samples from the other borings, the entire soil profile in the area.

3.1.2 Suspected Coal Tar Pit Investigation In the McDonald report, reference is made to a 20 foot deep pit filled with coal tar that is west of the relief gas holder base located on the south side of the site, just north of Washington Street. Soil samples were obtained by McDonald immediately west of the relief gas holder foundation at the ground surface and at a depth of five to six feet. Both samples indicated the presence of contaminants, which may or may not be due to the presence of a pit filled with coal tar. To determine if a pit does exist in this area, six borings (B-10 through B-15 on Figure II-l) will be drilled. The borings will be terminated at the groundwater table if field screening does not identify contamination (organic pockets, oil e with coal tar or spent oxide appearance) at shallower depths. If contamination is encountered above the groundwater table, the boring will be continued to the bottom of contamination and then three feet into native material below the contamination. Based on the McDonald report, the pit is anticipated to be 20 feet deep; therefore, the estimated maximum boring depth is 25 feet. Actual boring Part No. II. Section No. 3 Rev. No. 0 Rev. Date: 2/1/89 Page 7 of 25 depth will depend on field evaluation of material actually encountered. These borings will be sampled continuously using a continuous tube sampler in cohesive soil or tar material, and a split barrel sampler in granular soil.

If contamination is not encountered above the water table at borings B-10, B-ll, and B-13, then borings B-12 and B-14 will be drilled to 20 feet. These two borings will be drilled to check for the presence of contaminants below the water table, and will be sampled continuously using a continuous tube sampler in cohesive soil or tar material, and a split barrel sampler in granular soil.

If contamination is encountered in a boring, soil samples from that boring will be submitted for chemical analysis. For each boring where contamination is encountered, one sample of contaminated soil or tar material, and one soil sample of the native soil from three feet below contaminated material, will be submitted for chemical analysis. The purpose of this deeper sample is to determine if the contaminants have migrated beyond where they can be identified by field screening. For borings where no contamination is encountered, one soil sample from a boring will be submitted for chemical analysis and selected from an elevation so the entire area soil profile is represented when the samples from other borings are considered. Additional soil samples for chemical analysis will be obtained from boring B-10 located on Seventh Street. These additional samples will be discussed as part of the Seventh Street Investigation in Section 3.1.5.

3.1.3 Gas Holder Pit Investigation The gas holder pit is located in the court yard of the operations building The pit is reportedly 10 feet deep and is covered by a concrete slab. There are several openings covered with removable steel plates in the concrete slab that allow access into the pit. How the gas holder pit functioned is not known. After the pit was no longer used to hold gas, •Part No. II Section No. 3 Rev. No. 0 Rev. Date: 2/1/89 Page 8 of 25 it was reportedly used as a holding tank for ammonia water. Following shut down of- the gas production operation, the gas holder pit was reportedly used as a disposal pit. Employees have indicated that soil, old electric meters, and miscellaneous wastes were disposed of in the pit. During the site visit the pit appeared to be almost filled with solids and standing water. Discarded light bulbs, bricks, and miscellaneous trash were observed. Some of the materials appeared to be coated with an oil-like material. A surface water sample taken from the pit by McDonald contained some BTX and PAH contaminants. Since the contents of the pit are unknown, and since contaminants were identified in the surface water within the pit, an attempt will be made to characterize the material within the pit. To characterize the wastes in the pit, one boring (B-28) will be drilled at the edge of the pit using hollow stem augers. Care will be taken to advance the split spoon samples ahead of the hollow stem auger. A boring will not be placed at the center of the pit because the load bearing capacity of the slab covering the pit is unknown; therefore, it is not known if the slab can support the weight of a drill rig. The sampler will be advanced to the bottom of the pit, which is anticipated to be 10 feet. The boring will not be extended below the base mat of the pit to avoid potential release of contaminated water into the soil below the tank. Continuous split barrel samples will be obtained while drilling this boring. If the augers encounter an obstruction that cannot be drilled through before a depth of 10 feet is reached, the location will be offset and another effort will be made to advance the sampler.

This boring will not be grouted when completed; instead, the hole will be allowed to collapse or cave. One sample of the accumulated material at the bottom will be selected at the time of sampling and submitted for chemical analysis. Visual observations, odor and field screening with an HNU or OVA will be used to identify which sample is submitted for chemical analysis. In addition, one sample of the standing surface water in the pit will be collected and submitted for chemical analysis. Part No. II. Section No. 3 Rev. No. 0 Rev. Date: 2/1/89 Page 9 of 25

The pit will also be probed at several locations through openings in the slab. The probing will be done using a small diameter steel pipe or rebar. The objective of the probing will be to check if the pit depth is uniform and to get information about the depth of material in the pit at locations other than the boring in the pit. Obstructions in the pit fill may prevent reaching the pit bottom while probing; however, even refusal on solids in the fill may provide useful information about the contents of the pit.

3.1.4 Tar Separator Investigation The tar separator is a concrete structure that varies in depth from approximately six feet at the north end to nine feet at the south end. The separator has been backfilled with gravel, and it is not known if there is tar in the bottom or not. To determine if there is tar in the separator, two borings (B-18 & B-19) will be drilled to the bottom of the tar separator. If no tar is encountered within the tar separator, the borings will be advanced to a depth of five feet below the bottom slab to determine if tar has leaked out of the tar separator in the past. The estimated boring depths are 15 feet.

These borings will be drilled with a hollow stem auger. If possible, the auger will be used to drill through the concrete at the bottom of the pit. If the auger cannot penetrate the concrete, the concrete will be cored and the boring will be advanced below the concrete, using the rotary wash technique, which uses water as the drilling fluid; or with smaller continuous flight augers capable of penetrating the hole cored in the concrete. Sampling will consist of continuous split spoon samples for the full depth. Borings will be grouted from the bottom to the ground surface with a cement bentonite grout. If a flowable tar source is encountered within the tar separator, the bottom slab will not be breached and an additional boring will be placed outside the tar separator to a depth of five feet below the concrete slab to determine if tar has leaked from the separator in the past. Part No. II Section No. 3 Rev. No. 0 Rev. Date: 2/1/89 Page 10 of 25

Three soil samples from each boring will be submitted for chemical analysis. Soil samples will be submitted from the inside bottom of the pit, immediately below the concrete bottom of the pit, and from four to five feet below the bottom of the pit.

3.1.5 Seventh Street Investigation Seventh Street is a gravel road that has in the past been sprayed with oil for dust control. (During the site visit in September 1988, central portions of road were visibly darker, indicating oil had recently been applied.) During the EPA investigation performed by Ecology and Environment, Inc., a sample from the road surface that was sprayed with oil was submitted for chemical analysis and found to contain contaminants similar to those found in coal tar. To provide information on the vertical extent of contamination below the road, borings B-10, B-16, and B-17 will be drilled with a hollow stem auger using split spoon sampling techniques. Borings B-16 and B-17 will be terminated at a depth of five feet, and boring B-10 will be continued below five feet as part of the Suspected Coal Tar Pit Investigation.

Three soil samples will be submitted for chemical analysis from each of these borings. Soil samples will be obtained to define the variation of contaminant concentration with depth from the road surface to a depth of one foot, from two to three feet, and from four to five feet. (These intervals and depth of boring will be reduced as indicated in Appendix A if cohesive soil is encountered.)

3.1.6 Existing Well Investigation at Operations Building An existing hand dug well at the southeast corner of the operations building could provide a direct pathway for contamination to the aquifer. The well will be opened and visually inspected from the surface and the depth measured. The observations and measurements will be used to evaluate appropriate methods for eliminating the well as a potential migration pathway. Part No. II Section No. 3 Rev. No. 0 Rev. Date: 2/1/89 Page 11 of 25

3.1.7 Investigation of Drainage Ditch South of the Site Previous reports indicate material from the plant was disposed of in a ditch near the site. Borings B-29 through B-34 will be drilled along the alignment of a ditch that has recently been backfilled. It is not known if this is the ditch where plant material was dumped. The portion of the ditch where B-31 through B-34 will be drilled has been backfilled since the E&E/FIT investigation was completed and now contains a drainage pipe. The purpose of borings B-31 through B-34 is to determine if contaminants identified in the E&E/FIT investigation are still present, or if they were removed when the drainage pipe was installed. During a site visit by BVWMI personnel in September 1988, before the ditch in the vicinity of borings B-29 and B-30 was backfilled, it was noted that the north portion of the shallow ditch was one to two feet deep. Based on this observed depth, borings B-31 through B-34 will be drilled to a depth of approximately 15 feet or until native soil has been penetrated to a depth of three feet. Borings B-29 and B-30 will be drilled to determine if contaminants exist where the north portion of this ditch was once located. Borings B-29 and B-30 will be drilled to a depth of 15 feet or until native soil has been penetrated to a depth of three feet.

To determine if contaminants are being discharged from the drainage pipe that was installed along the alignment of the backfilled ditch where borings B-31 through B-34 are located, a sediment sample will be obtained from either the catch basin or one of the manholes located along the pipe (see Figure II-2).

Each of the possible sampling locations are located downstream of where the ditch has been backfilled. If sufficient sediment is not present in the catch basin or the manholes, no sediment sample will be obtained.

3.1.8 Locations of New Groundwater Monitoring Wells Monitoring well FI-2S will be installed to a depth of 40 feet adjacent to the existing 80 foot deep monitoring well FI-2. The depth of FI-2S has been selected based on the geology and the presence of contaminants in a Part No. II Section No. 3 Rev. No. 0 Rev. Date: 2/1/89 Page 12 of 25 soil sample collected from a depth of 35 feet while installing well FI-2. The boring log for well FI-2 indicates a silty clay layer with sand seams between the depths of 29 and 40 feet; however, the well installation log indicates that natural material caved in on the riser pipe between the depths of 22 and 40 feet. The caved material indicates there may be more sand at the location than indicated on the boring log; therefore, well FI-2S will be installed to monitor between the depths of 20 and 40 feet if the sand layer or layers are present throughout this interval.

Monitoring well FI-3D will be installed adjacent to monitoring well FI-3, which monitors between the depths of 18 and 37.3 feet, to determine if contamination identified in well FI-3 has migrated to greater depths. The boring for well FI-3D will be terminated when bedrock is encountered and will be installed to monitor the groundwater immediately above bedrock. The estimated depth of this well is 55 to 60 feet. Precautions will be taken during drilling to prevent migration of contaminants from contaminated to uncontaminated areas.

Monitoring well FI-6 will be installed north of Burlington Street. The purposes of this well are to collect background water quality data and to delineate the groundwater flow direction at the site. The location of this well is based on groundwater contours presented in the E&E/FIT report, which indicates the groundwater flows from the northwest to southeast, and on the slope of the land surface, which is to the southeast. This well will be screened in a sand layer or silty clay layer with sand seams located between the depths of 20 and 40 feet. If no contamination is encountered at this well based on field screenings, samples will be obtained and submitted for physical testing.

Monitoring well FI-7 will be installed adjacent to the plant and on the west side of the abandoned railroad right-of-way. This well will monitor a sand layer or silty clay layer with sand seams located between the depths of 20 and 40 feet. Well FI-7 is located to intercept contaminants that may be migrating from the central portion of the plant site. ' Part No. IJ Section No. 3 Rev. No. 0 Rev. Date: 2/1/89 Page 13 of 25

3.1.9 Samples from Existing Private Wells Five private wells are located west and southwest of the site. Refer to Figure II-2 for locations of FI-A, FI-B, FI-C, and FI-E. Residential well FI-D appears to be located near the intersection of Ninth Street and Jefferson Street. Groundwater from these wells has been sampled during quarterly sampling for IE and has shown trace levels or no contamination. Appendix A of the RI/FS work plan contains copies of the analytical results from the monitoring program on these wells. These wells may provide adequate monitoring to the west of the site if they are screened in the sand layer or silty clay layer with sand seams located between the depths of 20 and 40 feet. To determine the adequacy of these wells, well construction details will be investigated, and the wells will be sounded (if possible) to verify or to determine the well depths. If these wells are screened in the appropriate interval(s), they will be used to monitor the groundwater quality west and southwest of the site. If these wells are not screened in the sand or silty clay layer with sand seams, then a monitoring well, FI-8, will be installed west of the site to monitor within this zone. At present, the specific location of this well has not been selected.

3.1.10 Former Well East of the Power Plant Building Plant drawings from 1917 indicate that a 30 foot deep well was located 11 feet east of the former electric plant building. This well is presently not visible at the ground surface, and it is not known if this well has been backfilled. An attempt will be made to locate this well by shallow hand excavation and probing. If the well is located and it has not been backfilled, the size of the well and the well depth will be measured. This information will be used to evaluate appropriate methods to eliminate the well as a potential contaminant migration pathway. If the well has been backfilled, no action will be taken. Part No. II Section No. 3 Rev. No. 0 Rev. Date: 2/1/89 Page 14 of 25

3.1.11 Water Samples from Existing Monitoring Wells Monitoring wells FI-2, FI-3, FI-4, and FI-5 were installed by IE in 1985 and 1986, and have been sampled periodically. Monitoring wells MW-1 (DOT-1) and MW-2 (DOT-2) were installed for the EPA in 1987. All of these monitoring wells will be sampled.

3.2 ANALYSIS RATIONALE

The rationale for the selection of chemical analysis parameters is discussed in this section. A general discussion of analytical terminology is followed by a discussion of the analysis parameters as they relate to the two general matrices of concern: soil and groundwater.

There are two areas where the analytical rationale differ somewhat from the general soil and groundwater rationale. These areas are the Seventh Street Investigation, and the Gas Holder Pit Investigation. The Seventh Street Investigation is unique in that the objective is to identify PAH and BTX contamination due to road oil, and compare these results with PAH and BTX contamination found in FMGP wastes. The Gas Holder Pit Investigation is unique in that the nature of the waste is unknown, and may not relate to FMGP wastes found elsewhere at the site. Therefore, liquid and solid phase portions will be sampled, with complete organic and inorganic RAS analyses performed on them.

3.2.1 Analytical Terminology Appendix E presents tables listing the analyses that will be used on this project. These tables provide the names of the analysis, sample matrix (soil or water), method, name of analytes, and method detection limits.

The contaminants of concern defined in Part I of this POP and in the EE/CA and RI/FS work plans include BTXs, PAHs, metals, and cyanides. Part No. II Section No. 3 Rev. No. 0 Rev. Date: 2/1/89 Page 15 of 25

When trying to fully characterize the organic constituents in waste material that may be onsite, the organic RAS methods defined by EPA's Contract Laboratory Program (CLP) will be used. The organic RAS includes volatile organics analysis and the semivolatile organics analyses known as base/neutral and acid extractable. BTXs will be detected in the volatile organics analysis and the PAHs will be detected in the base/neutral extractables analysis.

When identifying the presence of only the BTXs or PAHs, the more limited aromatic organics analysis (Method 602) and PAH analysis (Method 610) will be performed respectively. Analysis for metals and cyanides will be performed following the inorganic RAS procedures.

3.2.2 Soil Investigation Objectives for investigation of the soil are threefold:

(1) identify the presence of contaminants;

(2) determine the extent of contamination, if present; and

(3) gather information necessary to evaluate potential remedial actions.

To meet the objectives of the investigation, soil samples will be collected from new monitoring wells and soil borings as indicated in Table II-2 for the EE/CA and in Table II-3 for the RI/FS. Figures II-l and II-2 show the locations of the borings and wells. Table II-2 and II-3 list each anticipated sample, the sample location, the anticipated sample depth, the reason for the sample; and anticipated laboratory analyses for each sample.

Most soil samples will be visually screened and screened with an organic vapor analyzer (OVA) or a photoionization detector (HNU). Odors will also be noted and recorded. The primary purpose of this screening is to identify contaminated samples for laboratory analysis and to identify the apparent presence of contaminants in the soil. Part No. II Section No. 3 Rev. No. 0 Rev. Date: 2/1/89 Page 16 of 25

To focus on the contaminants of concern identified by previous investigations in the EE/CA and RI/FS work plans, most chemical analyses to be performed on subsurface soil samples will include aromatic volatile organic compounds, PAHs, metals, and cyanide. Analyses for aromatic volatile organic compounds, including BTX, will be performed since these types of compounds are typically contained in coal tar waste products and light oils generated during the production of manufactured gas (EPA, 1988). Analyses for PAHs will be performed since these types of compounds are the primary constituents of coal tar waste products. Metals analyses will also, be performed to determine the potential presence of metals contamination from waste disposal practices. In addition, the metals analyses will provide information that will be required to evaluate potential remedial treatment and disposal actions. Total cyanide analyses will be performed because significant concentrations of cyanide have been associated with some spent oxide wastes from FMGP sites (EPA,1988).

Physical soil property analyses will be performed on representative soil samples collected during the drilling for background monitoring well FI-6. The physical analyses include grain size distribution, Atterburg limits, falling head permeability, field density, and moisture content.

These analyses will provide information necessary to classify the soils and to evaluate the potential for contaminant migration and will support evaluation of remedial technologies for soil. All soil samples submitted for physical analyses will be screened visually and with an OVA or HNU for signs of contamination. No contaminated samples will be submitted for physical analyses. Odor will also be used to indicate contamination.

A limited RCRA scan will be performed on material thought to represent source material. This scan will include reactive sulfur and cyanide, EP toxicity, and pH. This information will be of use when evaluating disposal options during remediation. Part No. _ II Section No _3 Rev. No. _ 0 ' Rev. Date: 2/1/89 Page 17 of 25

3.2.3 Groundwater Investigation The objectives for investigating groundwater are as follows:

(1) Determine the site specific hydrogeology.

(2) Determine extent and magnitude of contamination.

(3) . Provide information on groundwater flow characteristics so that contaminant migration can be evaluated.

(4) Provide information necessary to evaluate potential remedial response and technologies.

To meet the objectives of the investigation, four additional monitoring wells (FI-2S, FI-3D, FI-6 and FI-7) will be installed in the locations shown on Figure II-2. Optional well FI-8 will be installed only if adequate groundwater information for the west side of the site cannot be obtained from existing private wells. The private wells (FI-A, FI-B, FI-C, FI-D, FI-E) will be inspected and a determination made as to whether water samples would represent groundwater at the 20 to 30 ft. depth. Groundwater samples will be collected from all new wells plus the existing monitoring wells, FI-2, FI-3, FI-4, FI-5, MW-1, and MW-2, and existing private wells FI-A, FI-B, FI-C, FI-D, FI-E. As shown on Table II-3, the analyses for most well samples will be for PAHs, BTXs, Metals, and CN. As explained earlier for the soil samples, some full scan RAS organic and RAS inorganic analyses will be performed on selected samples so that the full range of contaminants affecting groundwater can be characterized. A summary of the laboratory analyses to be performed on groundwater samples collected during the field investigation is provided in Tables II-2 and II-3.

Chemical analyses for aromatic organic compounds, especially BTXs, will be performed since these types of compounds are typically contained in coal tar waste products and light oils which were generated during the production of manufactured gas (EPA, 1988). Analyses for PAHs will be performed since these types of compounds have been previously identified and are the primary constituents of coal tar waste products. Part No. II Section No. 3 Rev. No. 0 Rev. Date: 2/1/89 Page 18 of 25

Groundwater samples will also be analyzed for metals and cyanide. Metals analyses will be performed to determine the potential presence of metals contamination from waste disposal practices. In addition, metals analyses will provide information that may be required for subsequent remedial treatment and disposal actions. Analyses also will be performed to determine the presence of cyanide, due to the potential onsite disposal of iron oxide (gas scrubbing) wastes. Samples for metals and cyanide analysis will be filtered. . .

Field measurements of pH, temperature, specific conductance, and depth to groundwater will be made at the time of sample collection. Specific conductance and pH will provide additional water quality data. Temperature and conductivity will be measured at the same time since conductivity is a function of temperature. Measurement of these parameters is useful for evaluating treatment options. Depth to water will be measured at each sampling location to assist in evaluating the hydrogeology.

4.3.1 Drilling Methods and Well Installation The following sections describe information on drilling methods and well installation details, including soil boring and well locations, specific drilling and soil sampling methods, details of screen intervals and well construction, and monitoring well development procedures.

4.3.1.1 Soil Boring and Well Locations. Nineteen shallow borings (BIO through B28) will be drilled as part of the EE/CA. The locations of these borings are shown in Figure II-l.

An additional six shallow borings (B29 through B-34) will also be drilled as part of the RI/FS. The locations of these borings are shown in Figure II-2.

Four monitoring wells (FI2S, FI3D, FI6, and FI-7) will be installed as part of the RI/FS and the locations of these monitoring wells are shown in Figure II-2. If after inspection, the existing private wells FI-A, FI-B, FI-C, FI-D, and FI-E are determined to be inadequate for defining the limits of contamination west of the site, monitoring well FI-8 will be installed west of the site.

4.3.1.2 Drilling and Sampling Methods. Drilling and soil sampling methods for the shallow borings and monitoring wells are described here. For detailed sampling procedures, see Appendix A. Monitoring wells FI-2S, FI-6, FI-7, and FI-8 (if required), will be drilled using hollow stem augers. During auger advancement, samples will be collected continuously using a 5-foot long continuous tube sampler in cohesive soil, and a 2-foot long split barrel sampler in granular soil.

The drilling procedure for Well FI-3D will be different to prevent migration of contaminants from contaminated to uncontaminated zones. Part No. II Section No. 4 Rev. No. 0 Rev. Date 2/1/89 Page 6 of 24

Based on the boring log for well FI-3, it is anticipated that the zone of contamination at this location is above a depth of approximately 37 feet. Contaminant migration due to drilling will be prevented by installing and grouting in place a 6 inch diameter PVC casing after penetrating the zone of contamination identified in well FI-3. To determine if the zone of contamination has been penetrated, soil samples will be screened for the presence of contaminants visually and with an HNU or OVA. The casing will be installed after 4 feet of soil is encountered in which the presence of contaminants is not indicated by screening. It is estimated that the casing will be installed when the boring has reached a depth of 45 feet. Prior to installing the casing, the boring will be drilled and sampled as previously described for wells FI-2S, FI-6, and FI-7. The annulus outside the casing will be backfilled with cement-bentonite grout. The grout will be tremied into place to insure an effective seal is achieved. After the casing is grouted in place, and prior to drilling below the casing, all water and soil will be flushed from inside the casing and the drilling equipment will be decontaminated. Below the casing, the boring will be advanced using the rotary wash technique using potable water as a drilling fluid. The drilling fluid will be switched to bentonite mud if the cuttings cannot be removed using only water. Water produced during flushing will not be recirculated and will be drummed and stored pending analytical results and disposition. Water used for rotary wash drilling will be recirculated, and will be drummed and stored. Sampling during rotary wash drilling will consist of split barrel samples at 5 foot intervals until bedrock is encountered.

Borings B-29 through B-34 will be drilled to a depth of approximately 15 feet using hollow stem augers. Soil samples will be collected continuously using a continuous tube or split barrel sampler. Part No. II Section No. 4 Rev. No. 0 Rev. Date 2/1/89 Page 7 of 24

4.3.1.3 Screen Intervals and Well Construction. A typical well- construction diagram for wells FI-2S, FI-6, FI-7, and FI-8, is shown on Figure II-3. A typical well construction diagram for Well FI-3D is shown on Figure II-4. Table II-6 lists approximate well depths and screen intervals.

The wells will be constructed using 2 inch diameter, schedule 40 PVC. A minimum of 5 feet and a maximum of 15 feet of screen will be installed at the bottom of each well. The screen will be factory slotted schedule 40 PVC with 0.01 inch slots. Above the screen to 1.5 feet above ground surface, blank schedule 40 PVC will be used. All screen and riser pipe sections will be connected with threaded flush joints. For Well FI-3D, centralizers will be installed on the PVC riser pipe at 10 foot intervals within the 6 inch casing, to insure that the riser pipe is centered in the casing.

A filter, consisting of silica sand, will be installed around the screen to a minimum of 2 feet above the screen. Above the filter, a 3 foot bentonite seal will be installed and cement-bentonite grout will be tremied into place above the bentonite seal to ground surface. At the ground surface a steel protective surface casing with a lockable cap will be installed.

Following well development, a dedicated PVC bailer will be installed in each well. The bailers will be suspended from the well cap using nylon rope. Part No. II Section No. 4 Rev. No. 1 Rev. Date 3/3/89 Page 8 of 24

4.3.1.4 Well Development. The monitoring wells will be developed by bailing or pumping water from the wells until three to five casing volumes of water have been removed from the well, the discharge water is clear, and sounding indicates all loose material has been removed from the bottom of the monitoring well. Purged water will be collected and stored onsite.

4.3.2 Soil Sampling Methods for Physical Analyses

Three representative samples will be tested from well FI-6. See Table II-3 for the locations of these samples. All samples taken for physical analyses will be screened for contamination. No contaminated samples will be submitted for physical analyses. These samples will be collected using thin walled tube, split barrel, or continuous tube samplers.

The thin walled tube samples will be obtained in accordance with ASTM D 1587. Following sample recovery, the ends of the tubes will be sealed with wax. A spacer will be provided if partial sample recovery is obtained. A plastic cap will be placed and taped on each end of the tube.

These samples will be analyzed for moisture content, density, falling head permeability, Atterberg limits, and grain size distribution (if appropriate).

The split barrel samples will be obtained in accordance with ASTM D 1586 and the resistance to soil penetration will be measured and recorded. The split barrel or continuous tube sampler may be used when an undisturbed sample is not required (i.e., for Atterberg limit tests). For granular soils the split barrel sampler will be used to collect samples. Granular soil samples will be submitted for sieve analysis.

4.3.3 Soil Sampling Methods for Chemical Analyses Soil samples will be obtained from borings, monitoring wells, and a catch basin or manhole at the locations indicated in Tables II-2 and II-3 The Part No. II Section No. 4 Rev. No. 0 Rev. Date 2/1/89 Page 12 of 24 sampler will wear clean, disposable surgeons gloves and will use a clean stainless steel knife or spoon to obtain the sample. The knife or spoon will be decontaminated as described in Section 4.3.3.3. The portion of the samples for aromatic organic or volatile organic analyses will be collected first and placed in containers as quickly as possible to minimize volatilization and loss of contaminants. Following collection of aromatic or volatile organic samples, PAH, metals, and cyanide samples will be k collected. Soil samples will be placed in the sample containers specified in Table II-5.

4.3.3.1 Duplicate Samples. The number of duplicate soil samples to be collected is indicated in Table II-4. The duplicate sample will be collected by alternately placing a scoop of soil in the bottle for the sample and the bottle for the duplicate. The original and the duplicate sample will be placed in identical containers, preserved in the same manner, and submitted for the same analysis. The duplicate sample will be identified with a sample identification number as specified in Section 6.3, and the sample station will be documented in the field logbook.

The purpose of the duplicate sample is for laboratory QA/QC. Therefore, a duplicate sample should be taken from a sample that is suspected of having contamination. Using this criteria, the following locations have been selected for duplicate soil samples: FI-3D, FI-2S, B-13, B-19, B-22, and B-29. If these locations do not appear to be contaminated based on field screenings, alternate locations will be selected.

4.3.3.2 Equipment Blank. Equipment blanks (also known as rinsate blanks) will be prepared for both the continuous tube sampler and the split barrel sampler used during soil sample collection, before obtaining samples from FI-6. This rinsate blank will be used to measure the effectiveness of decontamination procedures. The rinsate blank will be prepared in the following manner: Part No. II Section No. 4 Rev. No. 0 Rev. Date 2/1/89 Page 13 of 24

o Decontaminate the soil sampling equipment using the procedure outlined in Section 4.3.3.3.

o Assemble the two halves of the sampler and screw on the driving tip with the sample catcher installed (if a catcher is used). Do not screw on the sampler head that contains the ball check valve.

o Pour High Pressure Liquid Chromatography (HPLC)-grade water through the partially assembled sampler from the top to the tip of the sampler, so that the water contacts only the inside of the sampler.

o Direct the water discharged out the end of the sampler directly into the sample bottles.

o The equipment blank for the continuous tube sampler will be analyzed for aromatic organics, and PAHs. The equipment blank for the split barrel sampler will be analyzed for volatile organics, base/neutral extractables, acid extractables, PCB*s/Pesticides, metals, and cyanide. See Table II-5 for required sample containers. See section 6.3 for the correct sample numbering procedure.

An additional equipment blank will be submitted in the event that heavy tar is encountered making extensive decontamination necessary.

4.3.3.3 Decontamination Decontamination of equipment will be performed to prevent the introduction of offsite contaminants into the borings, to prevent cross contamination of borings, and to prevent the removal of contaminants from the site. The decontamination procedure for drilling equipment will consist of the following:

o Remove soil with high pressure steam cleaner using potable water.

o Wash with ethanol. Acetone will be used if ethanol is unable to remove coal tar from the equipment.

o Wash with a high pressure steam cleaner using soap and potable water.

o Rinse with a high pressure steam cleaner using potable water.

This procedure will be followed for items such as augers, drill rods, and other drilling equipment. Part No. II Section No. 4 Rev. No. 0 Rev. Date 2/1/89 Page 14 of 24

The decontamination procedure for soil sampling equipment will consist of the following:

o Wash with brush and potable water to remove solids, o Wash with ethanol and allow to air dry. o Wash with soap and potable water, o Rinse with potable water, o Rinse with distilled water.

This decontamination procedure will be used for the split barrel and continuous tube samplers and other sampling equipment.

The decontamination procedure for PVC well construction materials (not the silica sand) will consist of the following: o Wash with a high pressure steam cleaner using soap and potable water.

o Rinse with a high pressure steam cleaner using potable water.

During decontamination, all the fluids produced that may contain hazardous substances will be contained and placed in 55 gallon drums.

4.3.4 Field Measurement of Permeability (Slug Tests) Slug tests will be performed on all existing, and new monitoring wells following the groundwater sampling effort. The purpose of this test is to determine the hydraulic conductivity of the water-bearing strata.

4.3.4.1 Data Gathering Procedures. General procedures for the slug test are discussed here. For detailed procedures, see Appendix B. Procedures for analyzing the data from the slug tests are located in Section 5.2.4 of the QAPP. Each slug test is conducted by measuring the static water level with an electric water level indicator, placing a pressure transducer (connected to a printer) below the water level, lowering a cylinder known as a slug bomb into the well above the static water level, starting the recorder, and submerging the bomb. The change in water level is recorded over time. Part No. II Section No. 4 Rev. No. 0 Rev. Date 2/1/89 Page 15 of 24

4.3.4.2 Decontamination Procedures. The slug bombs are decontaminated between uses by washing and rinsing with Liquinox soap and water, rinsing three times with ethanol, and rinsing three times with distilled water. The slug bombs are then allowed to air-dry on steel supports.

4.4 GROUNDWATER After the monitoring wells have been developed and water levels have stabilized, water levels will be measured and groundwater samples will be collected using bailers dedicated in each well. Private wells will be sampled using existing pumps if available after purging for several minutes. The samples collected from each well will be analyzed in accordance with the analyses listed on Table II-2 and II-3. During the opening of each well cap, the air above the security cap in the well casing will be monitored with a photoionization detector (HNU) or flame ionization detector (OVA). Results of this monitoring will be used to determine the required personnel safety level of protection for the sampler and will be recorded in the field logbook.

4.4.1 Sampling Methods for Groundwater Samples General sampling methods for groundwater samples are discussed in the following sections. For detailed sampling procedures, see Appendix B. Three to five well volumes will be purged from each well prior to actual sampling. Purged water will be collected and stored onsite. The volume of water in the well will be calculated based on the known depth and diameter of the well, and the height of the water column in the well. A dedicated bailer will be used to purge each well.

Samples, duplicates, and blanks to be submitted for aromatic organic analyses or volatile organic analysis (in the case of RAS organics) will be collected first. Each 40 ml vial will be filled completely with no visible air " bubbles, labeled, and placed in an iced cooler for preservation. Part N°- II Section No. 4 Rev. No. 0 Rev. Date 2/1/89 Page 16 of 24

Next, samples, duplicates, and blanks to be submitted for PAH analyses will be collected. Each sample will be poured in four 1-liter amber glass bottles with a Teflon-lined plastic cap and filled to the shoulders. The samples will be labeled and placed in an iced cooler.

If a complete RAS semivolatile organic analysis is required, a total of three 1-liter amber glass bottles will be filled. One 1-liter amber glass bottle will be used for base/neutral extractables, one for acid extractables, and one for pesticide/PCBs. These are to be prepared in the manner described above for PAH analysis. These samples will be labeled and placed in an iced cooler.

Samples, duplicates, and blanks to be analyzed for metals and cyanide will be collected last. Samples intended for dissolved metals analyses will be filtered, placed in one-liter polystyrene bottles, and preserved with HNO^. Samples intended for cyanide analyses will be filtered and placed in one-liter poly bottles and preserved with NaOH. Sample con­ tainer requirements and preservation requirements are summarized in Table II-5.

4.4.1.1 Field Measurements. Immediately following collection of the samples for chemical analyses, field measurements of temperature, specific conductivity, and pH will be taken. See Section 5.2.2.1 of the QAPP for the correct procedures.

4.4.1.2 Sampling Methods for Ground Water--Filtration. A disposable 500 ml Nalgene Sterilization Filter Unit with a 0.45 um pore size membrane and a squeeze handle vacuum pump will be utilized to filter ground water samples. Samples containing an oil phase will not be filtered. In this case, the project team will request on the sample tag that all phases be analyzed. The following filtration procedure will be used: Part No. II Section No. 4 Rev. No. 0 Rev. Date 2/1/89 Page 17 of 24

(1) While wearing clean impervious disposable gloves, place a 50 mm diameter glass fiber prefilter in the neck of the upper chamber of the filter unit, above the unit membrane.

(2) Connect the upper chamber to the receiving chamber and attach the pump tubing to the filter unit.

(3) Remove the lid on top of the upper chamber just prior to collection of the ground water sample.

(4) Collect a ground water sample with the PVC bailer.

(5) Fill the upper chamber of the filter unit with ground water from the bailer.

(6) Squeeze the handle of the vacuum pump to accelerate transfer of ground water from the upper chamber to the receiving chamber.

(7) After the water has been transferred to the receiving chamber, detach the receiving chamber from the filter unit.

(8) Pour the ground water from the receiving chamber into the sample containers specified on Table II-5 . for the filtered ground water.

(9) Repeat steps 5 through 8 until the required sample volume is collected.

(10) Repeat steps 1 through 9 for each ground water sample to be filtered using a separate filter unit and prefilters for each sample.

4.4.1.3 Equipment and Preservative Blanks. The number of groundwater blanks to be prepared is shown on Table II-4. One equipment blank will be prepared for one new bailer being installed in a new well, and one equipment blank will be prepared for the filter used to prepare samples for metals and cyanide analysis. One preservative blank will be prepared for each type of analysis requiring chemical preservation. Each blank will be given a unique sample identification number according to section 6.3 of this FSP. Part No. II Section No. 4 Rev. No. 0 Rev. Date 2/1/89 Page 18 of 24

The equipment blank for one new bailer to be installed in a new well will be prepared prior to sampling using the following procedure:

o Decontaminate the bailer and attach the rope to the bailer.

o Pour HPLC grade water into the bailer. Pour the water in the bailer directly into the sample bottles specified in Table II-5 for analyses of volatile organics, semivolatile organics, aromatic organics (BTXs), and PAHs. The equipment blank for metals and cyanide will be filtered.

A total of two preservative blanks will be prepared, one for metals, and one for cyanide. Each preservative blank will be prepared by filling the sample containers for the specified analyses with HPLC water and then adding the applicable type and volume of preservative to the containers, according to Table II-5.

One equipment blank will be prepared for filters used for metals analysis by pouring HPLC water through the filter, collecting in the filter bottle and then pouring into a metals container and sent for inorganic RAS analysis.

4.4.1.4 Duplicate Samples. One duplicate groundwater sample will be collected at wells FI-3 and FI-6 for each analysis. The duplicate sample will be collected simultaneously with the original sample by splitting each bailer of water between the original and duplicate sample. The original and the duplicate samples will be placed in identical containers, preserved in the same manner, and submitted for the same analyses. The original and duplicate samples for aromatic analysis will be prepared first. Each 40 milliliter vial should be completely filled immediately, rather than splitting the water between bottles and filling the bottles incrementally. The vials will all be filled from the same bailer if possible. If this is not possible, a minimum of two vials (one for the original sample, and one for the duplicate sample) will be filled from each bailer. If more than two vials can be filled from one bailer, the number of vials filled must be an even number (i.e. 2, or 4) so that an equal number of vials for Part No. II Section No. 4 Rev. No. 0 Rev. Date 2/1/89 Page 19 of 24 the original and duplicate samples are prepared. The vials must have no air bubbles when full. The samples for PAH's, total metals, and cyanide will be prepared next by splitting each bailer of water between bottles for the original and duplicate samples. Each bailer of water will be split by pouring one-half the water from the bailer into bottles for the original sample and the remaining one-half of the water into the bottles for the duplicate sample. The duplicate sample will be identified with a unique sample identification number, as specified in Section 6.3, and the sample station where the duplicate is collected will be documented in the field logbook.

4.4.1.5 Trip Blank. Trip blanks for aromatic organics analyses in groundwater will be prepared by the laboratory and will accompany sample containers transported to the site. Each trip blank will consist of four 40 milliliter vials filled with HPLC water. Trip blanks will remain onsite during sampling and will be submitted with groundwater samples shipped to the laboratory for analysis. Trip blanks will be used to determine whether Volatile Organic Carbons (VOCs) are introduced into groundwater samples as a result of onsite conditions or conditions during sample shipment. The trip blank bottles are not to be opened. Each trip blank will be given a unique sample identification number according to section 6.3 of this FSP.

4.4.1.6 Bottle Blank One bottle blank will be prepared for each analyses. The bottle blank will be prepared away from the site in an area free from possible contamination by volatile organics. HPLC water will be poured directly into the required sample bottles. The water for the cyanide and metals samples will not be filtered. The bottle blank sample will be preserved in the same manner as the groundwater, samples. The bottle blank should not be transported to the site, but should be packaged for shipment away from the site. Each bottle blank will be given a unique sample identification number according to section 6.3 of this FSP. Part No. II Section No. 4 Rev. No. 0 Rev. Date 2/1/89 Page 20 of 24

4.4.1.7 Decontamination of Sampling Equipment. The pH meter probe, specific conductance probe, and thermometer will be rinsed with distilled water before and after each use. Sampling equipment, including each dedicated bailer used to sample the wells, will be decontaminated by the BVWMI field project team according to the procedure given in Subsection 4.3.3.3.

4.5 SURVEY OF ONSITE WELLS An existing hand-dug well is located at the southeast corner of the operations building. This well is covered by a steel plate that will be removed during the field investigation so that a visual inspection can be performed from the surface. Observations, well dimensions, depth to water, and depth to bottom of well or any obstructions will be recorded during the EE/CA, for evaluation of possible measures to eliminate this well as a potential pathway for contaminants.

A second existing well, discussed in the RI/FS workplan, is located on the east side of the existing power house. Figure II-5 is a photocopy of a 1917 plant drawing that shows the location of a 30 ft. deep well. An attempt will be made to locate this well by shallow hand excavation. If the well is located and it has not been backfilled, the size of the well, depth to water in the well, and well depth will be measured. This information will be used to evaluate appropriate methods to plug the well and remove it as a potential contaminant pathway. If the well has been adequately backfilled, no action will be taken. If the well contains water, a water sample may be taken if the sample will provide information that samples from FI-4 will not provide, i.e. if wells draw water from different depths. FI-4 appears to be about 50 ft. downgradient from the location of the old well. Part No. II Section No. 4 Rev. No. 0 Rev. Date 2/1/89 Page 21 of 24

5.0 FIELD INVESTIGATION WASTES

The types of wastes produced during the field investigation include drill cuttings and soil, concrete, and water from well purging and decontamination procedures, and miscellaneous wastes, such as protective clothing. All field investigation wastes will be placed in DOT approved 55 gallon drums and stored onsite for later disposal. The wastes shall be segregated by type, such as soil, clothing, monitoring well development and purge water, and decontamination water in separate drums. In addition, soil cuttings and water from the wells will be segregated by boring or well. Appropriate disposal of contents in each drum can then be evaluated based on the results of chemical analysis. Part No. II Section No. 6 Rev. No. 0 Rev. Date: 2/1/89 Page 1 of 8

6.0 DOCUMENTATION

The sample custody and documentation procedures described in this section pertain to water and soil samples. Additional documentation procedures are located in Section 5.2.1 of the QAPP.

6.1 FIELD LOGBOOK All information pertinent to the EE/CA and RI/FS field investigation will be recorded in a bound logbook with consecutively numbered pages. All entries in logbooks and on sample documentation forms will be made in waterproof ink and corrections will consist of line out deletions that are initialed and dated. Entries in the logbook will include the following, as applicable:

o Name and title of author, date and time of entry, and physi­ cal/environmental conditions during field activity.

o Names and addresses of field contacts.

o Names and responsibilities of field crew members.

o Names and titles of any site visitors.

o Location, description, and log of photographs (if taken) of the sampling points.

Sampling situations vary widely. No general rules can specify the exact information that must be entered in a logbook for a particular site. However, the logbook will contain sufficient information so that someone can reconstruct the sampling activity without relying on the collector's memory. The logbooks will be kept in the BVWMI field team member's possession or in a secure place during the investigation. Following the investigation, the logbooks will become a part of the final project file. Part No. II Section No. 6 Rev. No. 0 Rev. Date: 2/1/89 Page 3 of 8

6.2 PHOTOGRAPHS If sampling locations are photographed, these photographs will show the surrounding area and reference objects. The film roll number will be identified by taking a photograph of an informational sign on the first frame of each roll of film. This sign will have the site name, initials of photographer, film roll number, and date written on it.

Example: FAIRFIELD FMGP Site SWA, Roll No. 1 April 15, 1989

Logbook entries of photographs will have four major components: photographers initials, roll number, frame number, and date.

Example: SWA, 1-1, 4-15-89

A description of the photograph content will also be entered in the logbook.

6.3 SAMPLE NUMBERING SYSTEM A sample numbering system will be used to identify each sample for chemical analysis. Anticipated sample numbers are listed on Table II-2 and II-3. The purpose of this numbering system is to provide a tracking system for retrieval of data on each sample. The sample identification numbers allocated for this sampling effort will be used on sample labels, sample, tracking matrix forms, chain of custody records, and other applicable documentation used during the sampling activity. As samples are collected, their sample identification numbers will be maintained in the field logbook.

Sample identification numbers for each sample collected will consist of three components: (1) a two character site identification code, (2) a two or four character sample location code, and (3) a three or four Part No. II_ Section No. 6_ Rev. No. Q Rev. Date: 2/1/89 Page 4 of 8 character sample identification number. Examples of completely numbered samples are shown below, with each numbering component identified.

FD - FI3 - SOI Soil sample number 1 (SOI), from monitoring well FI-3 (FI3), Fairfield FMGP site (FD).

FD - FI3D - W01D Duplicate groundwater sample number 1 (W01D), from monitoring well FI-3D (FI3D), Fairfield FMGP site (FD).

FD - BIO - S03 Soil sample number 3 (S03), from soil boring B-10 (BIO), Fairfield FMGP site (FD).

FD - EB1 - SOI Equipment blank number 1 for soil (SOI).

FD - PB1 - WOl Preservative blank number 1 for groundwater (WOl).

FD - TBI - WOl Trip blank number 1 for groundwater (WOl).

FD - BB1 - WOl Bottle blank number 1 for groundwater (WOl).

The site code (FD) will remain the same for all samples collected at the Fairfield site. Sample location codes will reflect sample location designations used throughout previous documents. Part No. II_ Section No. 6_ Rev. No. 0 Rev. Date: 2/1/89 Page 5 of 8

Duplicate samples will be designated by a D following the consecutive sample number.

Each sample collected must be assigned a unique sample number. Sample numbers do not change because different analyses are requested. For example, a water sample collected.at the same location, date, and time, for aromatic organics, PAHs, total metals, and cyanide analyses, would all have the same sample number, although the various sample aliquots would be placed in different containers.

6.4 SAMPLE DOCUMENTATION Each sample will be collected in the appropriate sample container and will be labeled with a sample label. Appropriate chain of custody procedures involved in the shipment of samples and completion of chain of custody records will be followed. In addition to sample labels and chain of custody records, a sample tracking matrix form will be completed. Examples of these forms are presented in Appendix D. The following sections describe procedures for completing sample documents.

6.4.1 Sample Labels The following information shall be included on the sample labels:

o Site name. v o Sampler. o Sample collection date and time, o Sample number, o Analysis, o Preservatives.

Information that is known prior to field activities (site name, sample numbers, etc.) can be preprinted on the sample tags. An example of the sample labels is shown in Appendix D. Part No. II_ Section No. 6_ Rev. No. 0 Rev. Date: 2/1/89 Page 6 of 8

6.4.2 Chain of Custody Records A laboratory chain of custody form will be completed for each sample shipment. An example of a chain of custody record is shown in Appendix D. After completion of the chain of custody form, the top, original signature copy of the chain of custody record is enclosed in a plastic bag and secured to the inside of the cooler lid. A copy of the custody record is retained for the sampler's files.

Shipping coolers will be secured and custody seals will be placed across cooler openings. Commercial carriers are not required to sign the custody form.

6.4.3 Sample Tracking Matrix A sample tracking matrix form will be used to record all pertinent information related to each sample. An example form is shown in Appendix D. The following information is required for the tracking matrix.

o Site name.

o Indicate the chain of custody report number.

o Enter the airbill number for the shipment.

o Enter the shipping date.

o List the QC lot numbers of the sample containers.

o Indicate the sample container type.

o Add any remarks on back side of form and note at the bottom of the form.

6.4.4 Custody Seals Custody seals will be used to assure the integrity of the sample from the time it is collected until it is opened in the laboratory. The seal must be attached so that it is necessary to break it to open the sealed container. Samples for the Fairfield FMGP site will be shipped in coolers. Each cooler will be sealed on two sides with custody seals. Examples of custody seals are shown in Appendix D.

6.5 CORRECTIONS TO DOCUMENTATION Unless prohibited by weather conditions, all original data recorded will be written with waterproof ink. No accountable serialized documents are to be destroyed or thrown away, even if they are illegible or contain inaccuracies that require a replacement document. Part No. II Section No. 6 Rev. No. 0 Rev. Date: 2/1/89 Page 8 of 8

If an error is made on an accountable document assigned to one individual, that individual shall make corrections by making a line through the error and entering the correct information. The erroneous information should not be obliterated. All corrections must be initialed and dated.

6.6 FINAL EVIDENCE FILES Once a project has been completed, the individual files will be assem­ bled, organized, and stored as final evidence for the project.

PART III

QUALITY ASSURANCE PROJECT PLAN Part Ill Section No. 1 Rev. No. 0 Rev. Date: 2/1/89 Page 1_ of 1

1.0 INTRODUCTION

To ensure that environmental monitoring and measurement efforts are documented and implemented with precision, accuracy, completeness, and representativeness, this QAPP has been prepared for the Fairfield FMGP project site.

A comprehensive and well documented QAPP is needed to obtain data that are scientifically and legally defensible and to achieve the levels of precision and accuracy specified by the data quality objectives which are defined in the EE/CA and RI/FS Work Plans, and developed further as field investigation objectives in the FSP (Part II, Section 2).

This QAPP presents the objectives, activities, and specific quality .assurance and quality control activities designed to achieve the data quality goals of the field investigation at the Fairfield FMGP site. This field investigation is being conducted for the Iowa Electric Light and Power Company by B&V Waste Management, Inc.

This plan is based on EPA guidelines specified in "Interim Guidelines and Specifications for Preparing Quality Assurance Project Plans", EPA, QAMS-005/80, December 1980. Part Ill Section No. 2 Rev. No. 0 Rev. Date: 2/1/89 Page 1 of 6

2.0 QUALITY ASSURANCE OBJECTIVES

The principal objective of the QAPP is to maintain the quality of opera­ tional activities and document the quality of data generated. Exper­ ienced and trained onsite personnel will conduct field operations. The project will also be staffed with personnel experienced in the technical and management disciplines appropriate for the Fairfield project.

The overall QA objective is to develop and implement procedures for field sampling, chain-of-custody, laboratory analysis, and reporting, that will provide legally defensible results. Specific procedures to be used for sampling, chain-of-custody, calibration, laboratory analysis, reporting, internal quality control, audits, preventive maintenance, and correctable actions are described in this QAPP. The purpose of this section is to define measurement objectives, detection limits, and QC parameters.

2.1 MEASUREMENT OBJECTIVES Measurement parameters vary depending upon the circumstances surrounding a sampling event, the type and concentration of material, and the media to be sampled. Measurements will be made to yield results that are representative of the media and conditions. To allow comparability of data bases, analytical data will be reported in units consistent with those used by other agencies and organizations to report previous analytical data. To assure that sample analyses and laboratory QA/QC procedures are consistent with U.S. EPA protocol, laboratories that participate in the U.S. EPA CLP will perform sample analyses.

For the Fairfield site, PAHs (particularly the carcinogens), some volatile organics (particularly BTXs), and metals and cyanide are the contaminants of primary concern. Analyses to be performed on each Part III Section No. 2 Rev. No. 0 Rev. Date: 2/1/89 Page 2_ of 6 matrix are summarized in the FSP, Section 3.2. These analyses include the organic and inorganic routine analytical services (RAS) which will analyze for a broad menu of potential contaminants including the contaminants of concern; more limited analyses intended to screen for the contaminants of concern; and RCRA screen analysis which will provide information relative to remedial options. The toxicological effects of the contaminants are discussed in the Preliminary Risk Assessment of the RI/FS work plan.

2.1.1 Detection Limits Detection limits for the analyses are presented in Appendix E. The detection limits used are based on the CLP detection limits for routine analytical services (RAS) or special analytical services (SAS).

There is a concern about excess cancer risks due to potential future ingestion of low concentrations of PAHs in groundwater. The EPA estimated concentration of total carcinogenic PAHs corresponding to an excess lifetime cancer risk of 1x10 ®, is 2.8 ng/1 in drinking water (ASTDR, 1987). To more fully assess the potential health risks at the site, some of the groundwater samples (see Table II-5 of the FSP) will be analyzed using larger sample volumes (4 liters) to allow the low detection limits listed in Appendix E. These low detection limits for PAHs in groundwater represent the lowest realistic detection limits which can be consistently achieved under Method 610 (Pace, January 13, 1989).

2.1.2 QC Parameters The objective of quality assurance is to assure that environmental monitoring data of known and acceptable quality are collected. To meet this objective, the following QC parameters are considered: precision and accuracy, completeness, representativeness, and comparability. Part III Section No. 2 Rev. No. 0 Rev. Date: 2/1/89 Page 3 of 6 2.1.2.1 Accuracy and Precision. The precision and accuracy quality control parameters measure the reproducibility of analytical results and the bias of a measurement method, respectively. Quality control limits for RAS analytical data are established under CLP guidelines stated in IFB WA-87-K236/K237/K238 for organics and in IFB VA-87-K025/K026/K027 for inorganics. Quality control limits for SAS data will be specified on the SAS request forms which are in Appendix D. Accuracy of chemical test results is assessed by establishing the average recovery. The recovery is determined by splitting a series of samples into two portions, spiking one of the portions (adding a known quantity of the constituent of interest), and submitting both portions for laboratory analysis as independent samples. The percent recovery is then calculated as follows:

% Recovery = SSR-SR X 100 SA

Where:

SSR = Spike Sample Results. SR = Unspiked Sample Results. SA = Spike Added from Spiking Mix.

The average recovery can then be calculated by taking the average of the individual recoveries for a given compound. In general, two types of recoveries are measured, matrix spike recoveries and surrogate spike recoveries. For a matrix spike, known amounts of standard compounds identical to the compounds present in the sample of interest are added to the sample. For a surrogate spike, the standards are chemically similar but not identical to the compounds in the fraction being analyzed. The purpose of the surrogate spike is to provide quality control on every sample by monitoring for unusual matrix effects and gross sample processing errors in analysis of organic compounds.

Precision of sample collection can be measured by comparing analytical results of samples and duplicate samples. The variation in the results Part Ill Section No. 2 Rev. No. 0 Rev. Date: 2/1/89 Page 4 of 6 is a measure of precision. Precision can be expressed as the relative percent difference (RPD), which is expressed as follows:

[°1 " D ] RPD = — — x 100 (Dx + D2)/2

Where:

RPD = Relative Percent Difference. D^ = First Duplicate Value (percent recovery). D^ = Second Duplicate Value (percent recovery).

2.1.2.2 Completeness. The precision and accuracy quality control limits (in terms of spike recoveries, replicate results, etc.) that must be met for the RAS analytical data to be considered acceptable are established under CLP guidelines as stated in IFB WA-87-K236/K237/K238 for organics and in IFB WA-87-K025/K026/K027 for inorganics.

The control limits specified above for accuracy and precision will be utilized to identify outliers (data results outside the specified control limits). If outliers occur or if contamination is detected in the blanks, the corresponding analysis results will be flagged and a memorandum will be written to the data user regarding the utility of the data.

The objective for completeness is that the investigation provide enough valid data that the goals of the field investigation are met. Completeness is the number of valid samples divided by the number of samples planned. The completeness goals for groundwater and soil are presented in Table III-l. Within these two categories are RCRA screen, organic RAS, BTXs, PAHs, metals, and cyanides. These goals are general requirements. Some individual sample results may be more important than others. Completeness should be evaluated after each sampling effort on an individual basis. Part III Section No. Rev. No. Rev. Date: 2/1/89 Page 5 of

2.1.2.3 Representativeness. Representativeness expresses the degree to which sample data accurately and precisely represent site conditions. The determination of the representativeness of the data will be performed by:

o Comparing actual sampling procedures to those delineated in the FSP (Part II).

o Comparing analytical results of field duplicates to determine the spread in the analytical results.

. o Examining the results of QC blanks for evidence of contamina­ tion; contamination may be cause for invalidation or qualifi­ cation of the affected samples.

A sample classified as questionable or qualitative by any of the above criteria will be invalidated.

2.1.2.4 Comparability Comparability expresses the confidence that one set of analytical data may be compared with another. Data sets that can be used for comparison are hazard criteria and studies conducted previously in the area. Comparability is maintained by usage of standard analytical methods, and units consistent with those used in previous studies.

2.2 FIELD INVESTIGATION OBJECTIVES The primary objectives of the field investigation include the collection of information on the nature, extent, and pathways of contamination. This information will be used to define source removal options, evaluate the public health risks posed by the contaminants, and perform a feasibility study of remedial measures. The specific sampling rationale for each sample matrix is discussed in Section 3.2 of the FSP (Part II). An itemized list of samples to be collected and associated rationale is presented in Tables II-2 and II-3. A discussion of the number of QC samples to be submitted for analysis is presented in Sections 4.3 and 4.4 of the FSP (Part II). Part III Section No. 3 Rev. No. 0 Rev. Date: 2/1/89 Page 1 of 1

5.2.2 Analytical Procedures. Calibration Procedures, and Frequency

5.2.2.1 Temperature. Specific Conductivity, and pH Measurement. Immediately following collection of samples for chemical analyses, temperature specific conductivity, and pH will be taken according to the following procedure:

(1) Water will be withdrawn from the well and poured into a clean glass container.

(2) The temperature of the collected water will be taken once immediately after the water is collected with a National Bureau of Standards mercury thermometer. The temperature will be recorded in a field logbook to the nearest degree Fahrenheit. The thermometer will be decontaminated by rinsing the thermometer with distilled water. If the water sample is visibly contaminated with an oily or greasy substance, ethyl alcohol will be used for decontamination of the thermometer. Decontamination fluids will be collected in a stainless steel bowl.

(3) The specific conductivity meter will be adjusted for the water temperature. The specific conductivity of the sample will be measured and recorded in a field logbook to the nearest micromho/cm. The specific conductivity meter will be decontaminated by rinsing the meter with deionized water. If the water sample is visibly contaminated with an oily or greasy substance, specific conductivity measurements will not be taken.

(4) The pH will be measured using a pH probe and will be reported to one decimal place in a field logbook. The pH probe will be decontaminated by rinsing the probe with deionized water. If the water sample is visibly contaminated with an oily or greasy substance, the pH of the sample will be measured with indicator paper having a pH range of 2 through 12.

(5) The temperature, specific conductivity, and groundwater pH will each be measured three times and averaged.

5.2.2.2 Water Level Measurement. Water levels will be measured using an electric water level indicator. Water levels for each well will be measured following well development and prior to well purging for sample Part III Section No. 5 Rev. No. 0 Rev. Date: 2/1/89 Page 7 of 12 collection after the water level in the wells has stabilized. The following procedure will be used by the BVWMI project team in measuring the water levels:

(1) Determine the length of the probe from the sensor portion of the probe to the first measure indicator on the cable by measuring this section with a tape measure to the nearest unit defined by the tape. Record this length. Also, measure the length of cable defined by the standard code markings and the length of cable corresponding to each five-foot of cable section up to 50 feet in length and record these measurements.

(2) Prior to first use, wash the portion of the cable that will enter the boring with alconox soap and potable water. Rinse with distilled water.

(3) Decontaminate the cable between wells by spraying the cable with distilled water and wiping with paper towels as the cable is rewound onto the reel.

(4) Turn on well probe and immerse probe end in a glass of distilled water to check probe batteries. Note instrument response as the sensor portion of the probe contacts the water. If no response, replace the batteries and try again.

(5) Lower the probe into the well by pulling the cable from the hand-held reel until the light comes on or buzzer sounds.

(6) Move the cable up and down while observing the indicator and note the exact length of cable extended from the tip of the probe to the top of the well casing. Record the cable length to the nearest l/100th of a foot, the station number, and the time and date of the measurement in the field logbook. Repeat this process three times to verify the water level.

(7) Decontaminate the cable. (See step 3.)

5.2.2.3 Volatile Organics. Soil borings and well installation sites will be scanned with a portable photoionization detector or portable organic vapor analyzer to aid in selecting soil samples to be analyzed and to verify that appropriate personnel protective equipment is in use. These air measurements will be in parts per million (ppm) based on the span gas used to calibrate the instrument (i.e., ppm benzene equivalent Part Ill Section No. 5 Rev. No. 0 Rev. Date: 2/1/89 Page 8 of 12 for HNU, ppm methane equivalent for OVA). Measurements will be recorded in the field log book, and actions will be taken as specified in the Site Safety Plan.

5.2.2.4 Sample Container Filling. The collected sample and its container represent one of the major avenues of personnel and environmental exposure. Precautions will be taken to ensure that samples removed from the site are inside the sample container and that no residue remains on the outside of the container.

To minimize the potential for contamination of the outside of a sample container, the following procedure will be used:

(1) Prior to sampling, a small plastic bag will be placed around the outside of the sample container and the container will be held in place with a rubber band or tape so that any sample spilled outside of the container will not contact the bottle.

(2) The sample will be transferred directly from the source or mixing pan to the sample container by use of a bailer or decontaminated scoop or spoon. The container will be filled to the appropriate level.

(3) The lip of the sample container will be wiped clean prior to capping.

(4) The sample container lids will be screwed on firmly without dislodging the lid lining or overtightening the lids.

(5) The sealed sample containers will be transported to the packaging area, where the outer plastic bag will be removed by the sampler without touching the external surface of the container more than necessary.

The instruments used during field activities will be calibrated in conformance with manufacturer's specification, at a minimum. Other equipment used in the field for personnel safety will be addressed in the Site Safety Plan. Part III Section No. 5 Rev. No. 0 Rev. Date: 2/1/89 Page 9 of 12

5.2.3 Internal Quality Control Blank and duplicate samples are included (when appropriate) with samples sent for laboratory analyses to monitor quality control of field sampling and laboratory analysis procedures. A list of QC samples can be found in Table II-4.

Samples for temperature, specific conductivity, and pH are not collected and retained. The primary QA objective for these data is to obtain reproducible measurements to a degree of accuracy consistent with limits imposed by the equipment. Reproducibility of measurements will be checked by taking three readings and by properly calibrating instruments.

5.2.4 Reduction of Data From Slug Tests. The data gathered during the slug tests are used to calculate hydraulic parameters. The hydraulic conductivity is calculated using the Hvorslev method. Transmissivities and storativities are determined using the curve matching method.

5.2.4.1 The Hvorslev Method. Using this method, the data are plotted as: In H-h H-Ho versus time (t)

H is the original level of water in the well, h is the level of water in the well at any given time during the test, and Ho is the level of water in the well immediately after a slug has been added to the well. Water levels must be measured from a common datum. The hydraulic conductivity is calculated from the equation:

K = An (LlR) 2 LTo

r is the radius of the well, R is the radius of the piezometer (or screen), L is the length of the screened interval, and To is the basic time lag. The basic time lag is determined from the plot of In H-h versus t and is equal to t when In H-h equals -1. H-Ho H-Ho Part Ill Section No. 5 Rev. No. 0 Rev. Date: 2/1/89 Page 10 of 12

5.2.4.2 The Cooper Method. The Cooper formulation calculates the transmissivity of an aquifer by matching a plot of relative head (linear scale) versus time (logarithmic scale) to one of a set of type curves. The method assumes that the change in head after a known volume of water is injected or removed is instantaneous and the well (non-flowing) is screened over the entire thickness of an artesian aquifer. It is directly applicable to fully penetrating screened wells in confined aquifers, but may be used to determine the transmissivity of the portion of an aquifer over which a partially penetrating well is screened, assuming no vertical flow occurs.

5.2.5 Data Validation Field logbooks, documentation forms, calculation worksheets, etc., utilized for the Fairfield FMGP project will be retained. These data will become a part of the final evidence file. Raw data will be summarized in the RI report.

5.2.6 Data Assessment The BVWMI project team will assess data to assure that QA objectives are met.

5.2.7 Preventive Maintenance Preventive maintenance of equipment is essential if project resources are to be used in a cost effective manner. Preventive maintenance will take two forms: (1) a schedule of preventive maintenance activities to minimize downtime and ensure accuracy of measurement systems and (2) availability of critical spare parts, backup systems, and equipment.

Contract agreements with firms providing services will specify that equipment used at the site will be maintained in safe working order. Any equipment or device determined not to be in safe working order by field team personnel or the Site Safety Coordinator will be replaced, repaired, or corrected at the subcontractor's expense. Part III Section No. 5 Rev. No. 0 Rev. Date: 2/1/89 Page 11 of 12

5.2.8 Procedures to Assess Precision. Accuracy, and Completeness No quantitative levels for precision and accuracy are specified for field measurements. However, proper maintenance, calibration, and operation (per manufacturer's recommendations) of instruments will be followed to ensure instrument accuracy so reliable results will be obtained. Instruments will be calibrated at recommended intervals to assure measurement accuracy. Multiple readings and analysis of duplicate samples will be performed to measure the precision of field measurements. Data completeness will be assessed by the BVWMI project team.

5.2.9 Corrective Action If quality control audits of data result in detection of unacceptable data, the site manager will be responsible for developing and initiating corrective action. Corrective action for field measurements may include:

o Repeat the measurement to check the error.

o Check for proper adjustments for ambient conditions such as temperature.

o Check the power supply to the instrument, if any.

o Check the calibration.

o Replace the instrument or measurement devices.

Corrective action for sampling procedures may include:

SAMPLING PROCEDURES FOR GROUNDWATER INVESTIGATION Part No. IV. Section No. B_ Rev. No. 0 Rev. Date 2/1/89 Page 1 of 4 Groundwater Sampling Note: Duplicate groundwater samples will be collected from wells FI-3 and FI-6, see Section 4.4.1.4 of the FSP. For sample numbers, see Tables II-2 and II-3. For sample preservation requirements, see Table II-5. Inspect and record any evidence of damage to the well cap and lock and record any evidence of forced entry.

1. Open well cap and scan the air in the well with an OVA or HNU. Record reading in the field logbook and comply with procedures prescribed in the Health & Safety plan. 2. Measure water level in the well according to section 5.2.2.2 of the QAPP. 3. Purge the well of 3 to 5 times the casing volume of water. If well is dry prior to purging 3 to 5 volumes, purging is considered completed. The volume of the well will be calculated based on the known depth of the well, well diameter, and the elevation of the water in the well as measured in step 2 above. If recovery does not occur in a reasonable time, less purge water should be removed. Total purge water volume should be recorded in the field logbook. 4. Collect groundwater samples according to section 4.4.1 of the FSP. Divide, the samples as follows; following the procedure outlined in section 4.3.3 the FSP, and 5.2.2.4 of the QAPP. Existing private wells will be sampled using the tap if available, after purging for several minutes.
