Pursuant to a Cooperative Agreement (V-96089702-0) between the U.S. Environmental Protection Agency (EPA) and the Oregon Department of Environmental Quality (DEQ), the DEQ conducted a Preliminary Assessment (PA) at the Grant Warehouse Residential Area located near NE Fremont and NE Martin Luther King, Jr. Blvd. Portland, Oregon.

PAs are intended generally to identify potential hazards at a site, identify sites that require immediate action, and to establish priorities for sites requiring in-depth investigations. The PA is based on readily available information about the site and is not a full investigation or characterization of the site.

The PA includes the identification of primary and secondary targets as part of each pathway conclusion. A primary target is a target which has a relatively high likelihood of exposure to a hazardous substance. A secondary target is a target which has a relatively low likelihood of exposure to a hazardous substance.

The PA was conducted to identify potential public health and environmental threats related to the site. The PA is based on data derived from the sources listed in the reference section of this report. The scope of the investigation includes review of available file information, interviews, a comprehensive target survey, and limited soil and groundwater sampling.

Grant Warehouse Areawide June 20, 2013 CERCLIS No. ORSNF0012090 Page 1 2.0 SITE DESCRIPTION, OPERATIONAL HISTORY, AND WASTE CHARACTERISTICS

Grant Warehouse in northeast (NE) Portland was used as an auto repair facility, a welding shop, a lead- acid battery business, and a metallurgical laboratory before being demolished in the mid-2000s. Off site residential soils were screened for metals during an investigation and emergency removal of hazardous substances by the EPA Emergency Response Program. Analysis of off-site samples confirmed concentrations of lead above residential risk-based concentrations (RBCs). This PA focuses on defining risk and sources of lead within 100 yards of the former Grant Warehouse.

2.1 Site Description The site is defined as a 100 yard radius from the former Grant Warehouse located at 3368 NE Martin Luther King, Jr. Blvd (MLK Blvd)., Portland, OR, currently a vacant lot. The surrounding area is primarily a residential neighborhood, with a commercial corridor along Martin Luther King Blvd (Hwy 99E). The site is bordered by residential homes to the east, empty lots directly to the north and south and commercial businesses to the west (gas station). The site is also located within the city of Portland Interstate Corridor Urban Renewal area and is zoned for high density residential on the western portion of the area and residential in the eastern portion. The site layout is shown in figure 2.

The 1901, 1909, 1928 and 1950 Sanborn Fire Insurance Maps were obtained from the Oregon State Library and a Phase I for McCann/Lenske Property. Aerial photographs of the site were obtained from the McCann/Lenske Property Phase I for the following years: 1936, 1948, 1956, 1964, 1973, 1980, 1990, 1998 and 2002. Residential housing and scattered vacant lots are within the 100 yard radius site area in Sanborn Insurance Map. Commercial businesses and residential dwellings are located along NE MLK Blvd (formally Union Ave) in 1909 and 1928, but by 1950 all properties along NE MLK Blvd are commercial.

2.2 Ownership and Operational History The former Grant Warehouse (ESCI #2385) in NE Portland was used as an auto repair facility, a tire store, welding shop, smokehouse/sausage factory. From 1980 to 1998 the site was used to recover precious metals from ore, liquids and process wastes from other facilities. In 1998, Portland Police responded to a dispute on site and found numerous chemical and waste containers stacked wall-to-wall in the building and yard. DEQ inspectors documented thousands of chemicals, including corrosives, oxidizers, flammable/explosives and dusts containing very high levels of lead. DEQ requested EPA assistance to abate the substantial endangerment the property presented to the community. Approximately twenty off-site residential soil samples were collected in 1998 and eight lead concentrations were above residential risk based concentrations. EPA removed all loose and containerized hazardous materials from Grant Warehouse in 1998 and early 1999. Demolition of the building occurred in 2005 after considerable efforts to characterize and dispose of the contaminated building materials. The site received a No Further Action (NFA) determination from DEQ in July 2006, however, this NFA only included the Grant Warehouse property and did not include the off site residential soils. DEQ conducted a limited evaluation between the Grant Warehouse and offsite soils in 2006(see section 2.3 for discussion).

Grant Warehouse Areawide June 20, 2012 CERCLIS No. ORSNF0012090 Page 2 McCann/Lenske (ESCI #4711) at 427 NE Cook Street, directly to the south of the Grant Warehouse operated as a dry cleaner, vehicle repair and gas station, and battery manufacturing facility. The Pacific Battery Manufacturing Facility building was built in 1948 and operated until at least 1970. During demolition activities in 2006, soil discoloration, possibly from lead acid, was found below the subslab and found to have elevated concentrations of lead and petroleum compared to RBCs. Soils were removed and confirmation samples were below residential risk based concentrations. The site received a NFA determination from DEQ in August 2007.

Tax lots in the eastern portion of the 100 yard radius have been single residential housing or townhomes since 1901 with increasing density until all tax lots were filled sometime between 1924 to 1950.

2.3 Source Areas and Waste Characteristics The sources of lead in residential soils at this site are largely unknown. The 1998 work did not specify exact locations of soil samples to help determine a probable source of the lead concentrations. There are several possible sources, but no specific lead source has been attributed to the soils.

Areas of potential source contamination are:

Air deposits from Grant Warehouse dust may have been drifted towards residential homes. During demolition of the Grant Warehouse, two chimneys were determined to be contaminated with lead concentrations. In 2006, DEQ conducted a limited evaluation between metal concentrations in offsite soils vs. chimney soot metal concentrations. Grant warehouse chimney soot concentrations were elevated for cadmium (198 mg/kg) and silver (146 mg/kg); surrounding residential soil average concentrations (0.46 mg/kg and 0.8 mg/kg respectively) were observed to be lower than background concentrations. The chimney soot lead concentration was 3,000 mg/kg and the average residential soil concentration observed was 346 mg/kg. The evaluation was inconclusive demonstrating Grant Warehouse as a single source, suggesting other sources may have contributed.

During the 2006 demolition of the Pacific Battery Manufacturing building, four wood covered depressions were located in the northern floor area. Soil with elevated petroleum and lead concentrations (up to 67,100 mg/kg) were discovered and removed in the NE portion of the property to below residential risk based concentrations. Yellow soils staining in the elevated concentration area could be attributable to acid releases to the ground. Available Sanborn Map records do not indicate any dedicated buildings for smelting occurred on site.

The MLK Blvd. thoroughfare, also Oregon Route 99E, was the main North/South automobile route through east Portland prior to the completion of Interstate 5 in 1966. High volumes of automobile and large truck exhaust prior to the leaded gasoline ban in 1986 may also have increased nearby residential soil lead concentrations. Parking strips, along residential streets, may also have increased lead concentrations in soils.

Many residential houses in the area were built and painted prior to the United States Consumer Product Safety Commission’s lead paint ban in 1977. Flakes of historic lead paint may occur in site soils, possibly concentrated around house footprints and drip lines.

Grant Warehouse Areawide June 20, 2012 CERCLIS No. ORSNF0012090 Page 3 3.0 LIMITED SOIL SAMPLING METHODS AND RESULTS

In order to evaluate potential source areas at the site, DEQ performed a limited soil testing effort as part of the PA on May 2-3, 2013. Soil testing was conducted using an on-site x-ray florescence (XRF) analyzer, and soil samples were collected from 4 locations to qualify the XRF on-site data. Testing was performed in accordance with the Preliminary Assessment Work Plan, Grant Warehouse (former) area wide dated April 24, 2013, and the DEQ/EPA PA/SI Investigations Quality Assurance Project Plan dated August 2012.

Prior to field activities, a site-specific health and safety plan was prepared in accordance with the Occupational Safety and Health Act (OSHA) and the Oregon Administrative Rules (OAR). DEQ also consulted with the Oregon State Historic Preservation Office (SHPO), the Confederated Tribes of Grand Ronde, Confederated Tribes of Siletz Indians, and the Confederated Tribes of Warm Springs Indian Reservation, as required by Section 106 of the National Historic Preservation Act. A response letter from SHPO reiterated the requirement of ceasing activities should a cultural resource be found during the investigation. No response was received from any Tribal government.

3.1 Sample Collection Methods and Rationale DEQ conducted surface soil (0-5 inches below ground surface) testing within a 100 yard radius of the former Grant Warehouse site. The sampling locations were identified as the most reasonable locations of residential lead exposure, including drip lines surrounding the house footprint, gardens, play areas, and parking strips in front of each property. DEQ staff used the XRF analyzer to screen soil for metals in 68 locations selected in the field on bare soil or in areas of sparsely vegetated landscape. Soil samples were collected at 4 locations, or approximately 10% of locations with XRF readings above 200 mg/kg lead, and sent to a laboratory for analysis. XRF monitoring locations are shown on Figures 5 and 6.

All non-disposable field equipment and devices were decontaminated to prevent cross-contamination between sampling events. The XRF was calibrated daily using the procedure outlined in the Sampling and Analysis Plan (22). The Relative Standard Deviation calculation met the less than 20% criteria and available in Appendix E.

3.2 Laboratory Analytical Methods All soil samples were submitted to ESC Lab Sciences of Mt. Juliet, Tennessee and were analyzed for RCRA 8 metals by EPA 6010/6020/7000. Sample collection locations are also shown on Figure 5. Complete analytical reports are included in Appendix C.

3.3 Soil Testing Results and Discussion

Soil was tested using the XRF analyzer at 7 property locations and on 10 parking strips (grass islands between the sidewalk and the roadway) locations on May 2, 2013. One of the 7 property locations contained 3 new townhouse units. The average XRF results for each location and normalized values (shown in brackets) are presented below. Rationale for data normalization is discussed below in Table 3.

Because the average of 687, 1189, and 648 suggests an inaccurately high average value, the average of 687 and 648 (668) will be used as the average XRF value for this location

Soils samples were collected from 4 locations on May 3, 2013. The sampling locations were selected consistent with the range (low, medium low, medium high, high) of XRF data collected from the previous day. Soil analytical results are:

Table 2: Laboratory Analytical Results for Lead in Soil Soil Sample Analytical Results - May 3, 2013 Sample Number Lead Concentration (mg/kg) 436-1 (436 NE Ivy Street XRF location 5 @ 5 inches BGS) 710 436-2 (d) (436 NE Ivy Street XRF location 5 @ 5 inches BGS dup.) 2500

516-3 (516 NE Ivy Street XRF location 4 @ ground surface) 280

504-4 (p) (parking strip location 8 @ ground surface) 43

445-5 (445 NE Cook Street XRF location 7 @ ground surface) 490

Based on comparison of the soil sample laboratory analysis and the raw XRF field data, the XRF results should be corrected upward by 10.84 percent. However, based on professional judgment, we recommend two data be adjusted in order to determine a more accurate XRF correction factor. First, as noted Table 1, the average value at location 7 at 445 NE Cook Street will be based on two of the three readings. The middle reading appears to be an anomaly compared to all other data readings/location for this site.

The second adjustment relates to the duplicated laboratory lead analysis for sample 436-2 (d) which also appears to be an anomaly (2500 mg/kg for the duplicate vs. 710 mg/kg for the primary sample shown in

Grant Warehouse Areawide June 20, 2013 CERCLIS No. ORSNF0012090 Page 6 Table 2). The duplicate will not be used as part of the data set to determine the correction factor. This decision considers other metal concentrations in the two samples are very similar while the lead values disagree by almost a factor of 4 (see Appendix C Lab Results sample 436 -1 and 436 2 (d)). Considering these sensible adjustments, the XRF values at each location will be corrected upward by 2.01 percent. Table 1 shows the corrected or “normalized” value for lead in brackets. Table 3 shows the correction factor determination.

It appears that the property located a 436 NE Ivy Street, which is directly east of the former Grant Warehouse property, has consistent, moderate concentrations of lead in soil except for the locations tested in the parking strip and near the south west corner of the property. Soil sample readings taken at 5 inches BGS in the location of the two highest surface readings show similar or slightly higher lead concentrations in the deeper tests. Approximately ½ of the sample locations tested were greater than 400 mg/kg, DEQ’s risk screening level for direct contact with residential receptors.

Three other properties had locations above 400 mg/kg but it appears that these concentrations are inconsistent with concentrations detected at other locations within each property as follows: x 506 NE Ivy Street: Three of the eight locations tested were greater than 400 mg/kg. The soil at two of the three locations (sample locations 7 and 8) contained burned charcoal pieces and debris, indicating non native material, possibly from a burn pile. x 446 NE Ivy Street: Two of five locations tested greater than 400 mg/kg. One of these locations was near an old metal fence with peeling and chipping paint, and the other in close proximity to the house where impact from lead-based paint would be expected. x 445 Cook Street: Three of 10 locations tested greater than 400 mg/kg. All three locations are in close proximity to the house drip line, and the location with the highest, consistent reading was directly below the house drip line (location 8).

Based on the results of the soil monitoring and analysis, it appears that 436 NE Ivy Street is the only property that may have been affected by discharges or releases associated with activities at the former Grant Warehouse facility. However, limited monitoring conducted for this PA is insufficient to draw such a conclusion without other lines of evidence connecting the contaminants at both properties. Other sources of lead from leaded gasoline (high volumes of cars and large trucks), nearby historic industrial facilities in the general vicinity, and lead based paint may also have contributed to the moderate lead concentration in soil on this property.

Grant Warehouse Areawide June 20, 2013 CERCLIS No. ORSNF0012090 Page 7 4.0 GROUNDWATER PATHWAY

4.1 Regional Geology and Hydrogeology The City of Portland is located along the Willamette River, near the confluence with the Columbia River within the Willamette Valley geologic province of Oregon. Columbia River basalt is overlain by the Troutdale formation, a layer of sandstone and gravel eroded from Columbia Basin and Cascade Mountains up to 1500 feet thick (accumulated 10 to 2 million years ago). The Troutdale formation was created as volcanic activity, mudflows, and continuing deformation repeatedly transformed the Willamette River into closed drainage basins, forming large lakes. Silt, sand, and gravel were deposited by this process as well as by the Columbia River (2).

4.2 Site Geology and Hydrogeology The geology of the area consists of 180 feet of alluvium overlying the Troutdale Formation. Brown silt and/or fine sandy silt are found from the ground surface to about 16 feet below grade, where a fine to medium sand was encountered. Thin silt lenses (0.5 foot to 1 foot thick) are occasionally encountered. Sands and gravels extend approximately 40 feet below grade to the Troutdale Formation. Subsurface explorations at the property, to a depth of 46 feet, did not encounter groundwater. A monitoring well installed approximately ¼ mile to the west of the property encountered groundwater at 163 ft below grade. Groundwater flow is expected to be generally to the west (1).

4.3 Groundwater Targets A search of the Oregon Water Resource Department’s GRID (well-log) database (4) was completed for a four-mile radius of the site (see Figure 3) in order to identify the location of domestic or community water wells. In addition, the Oregon Department of Human Services’ Drinking Water Program (DWP) database (5) was searched for information on the community water system. The radial distance of domestic, community, and municipal wells from the site are presented on the table located on the following page. This table also includes the secondary target population data for people served by wells at various distances from the site. Summary tables of well logs within the four mile radius and select well logs are included in Appendix D.

The nearest domestic wells are greater than 1 mile from the site. The City of Portland generally supplies domestic drinking water within city limits.

4.3.1 Community Water Systems Information There are no community water system utilizing groundwater are located within a 4-mile radius of the site. Systems located in Oregon are regulated by the DWP. To be a regulated system, in Oregon, the water system must have at least four service connections or serve water to public or commercial premises which are used by an average of at least 10 individuals daily at least 60 days each year.

4.3.2 Domestic Well Information There are 42 domestic wells located with a 4 mile radius of the site and a majority of the wells are primarily completed in the alluvium aquifer, ranging from approximately 38-200 feet below ground surface. Well log summaries including total depth and depth to water are included in Appendix D along with select well logs.

4.3.3 Groundwater Resources Groundwater is used for industrial processes and landscape irrigation within the four mile radius. The site is not located within the projected 10 year travel time drinking water protection area.

4.4 Groundwater Conclusions Approximately ¼ mile to the west of the property encountered groundwater at 163 ft below. The nearest domestic groundwater well is 1-2 miles away. Given that the contaminants of concern at this site are metals that have limited solubility and the distance between the site and drinking water wells, drinking water users within the 4-mile radius are considered secondary targets.

5.1 Area Setting The area is temperate, receiving approximately 43 inches of precipitation annually. The average temperature is 54 degrees Fahrenheit (7). The 2-year, 24 hour precipitation event is 2.5 inches (8). The site is located outside of the 500 year flood plain (Zone X) (9). Site soils encountered during the limited site evaluation consisted of fill and alluvium deposits.

The City of Portland is located in the Lower Willamette River Watershed Basin. The Willamette River originates in the Cascade Mountains and Coast Range, and flows into the Willamette Valley. The Willamette River is a tributary of the Columbia River and is 187 miles long and drains more than 11,478 square miles (10).

The Lower Willamette River is a water quality-limited stream under Section 303(d) of the Clean Water Act for temperature, bacteria and mercury.

5.2 Surface Runoff and Probable Point of Entry (PPE) The site is relatively flat and covered by mostly the building footprints and vegetated yard areas. Surface water runoff either infiltrates into the subsurface or enters the City of Portland stormwater system (19). Stormwater is sent to a combined stormwater/sewer system that is sent to the City of Portland Columbia Boulevard Wastewater Treatment Plant, which is treated and enters the Columbia River at Hayden Island near the railroad bridge. The combined sewer overflow enters the Willamette River at Outfall 46 during extreme overflow events and is the PPE. Outfall 46 is not specifically measured but the City of Portland estimates an average of 2.5 overflows (duration unknown) in the past six winters for outfalls in this area (20). The site drainage area is approximately 2.6 acres. The storm water routes, PPE, and 15 mile in water total distance limit (TDL) are shown on Figure 4.

5.3 Surface Water Targets The site is located approximately 1 mile due east of the Willamette River. The area between the site and the Willamette River is developed and is in primarily residential and commercial use.

The nearest active river gauging stations were identified as USGS 14211720- Willamette River at Portland and USGS 14144700 Columbia River at Vancouver, WA. The Columbia River station is approximately 4 miles upriver from the mouth of the Willamette. Willamette River annual flow rates are over 20,000 cubic feet per second (cfs) but less than 41,000 cfs for the past 10 years. The Columbia River is only measured in gage height, where for 2012 maximum gage height was 15.68 ft; minimum gage height was 0.37 ft.

Potential discharges were evaluated for a 15 mile downstream TDL from the probable PPE. The TDL is shown on Figure 4. Multiple water rights were identified within the TDL on the Willamette and Columbia Rivers. The water rights are primarily for the extraction of water for irrigation use (12). There are no community or public surface drinking water intakes within the 15 mile TDL. There are approximately 20 miles of wetland frontage along river for each TDL.

The Oregon Department of Fish & Wildlife documents fish consumption throughout Oregon. The table below lists the calculated fish caught at the corresponding section of river for the year 2010-2011. However, the report does not specify where the fish were caught (13).

6.1 Physical Conditions The site is primarily a residential neighborhood covered with building foundations and vegetated yard areas. Site photographs are included in Appendix F. Soil type is an ‘Urban land-Latourell complex’, a well drained loam with 0 to 3 percent slopes.

6.2 Soil Targets Land use in the vicinity of the site has been primarily residential. The closest residence is located on the site. Resource uses (commercial, industrial) are currently not on the property. Zoning permits high residential use in vacant lots between NE Ivy Street and NE Cook Street. Commercial use is identified for the vacant lots between NE Ivy Street and NE Fremont Street. No terrestrial sensitive environments were identified on the property. Albina Head Start is approximately 700feet from the center circle. Boise-Eliot Elementary school is located 0.54 miles (2,853 feet) from the property. The site is located in an area with 32% of people living below the poverty level.

The population located in the vicinity of the site and surrounding area is provided below. DEQ utilized the Circular Area Profile population tool at the Missouri State Data Center (18) to determine the estimated radial population. The Circular Area Profile population tool uses the population data from the 2010 U.S. Census (6).

Radial Distance from Site Population

0 to ¼ mile 649 ¼ to ½ mile 5,790 ½ – 1 mile 17,647 Total 24,086

6.3 Soil Exposure Pathway Conclusions Based on the results of the soil monitoring and analysis in section 3, it appears that lead concentrations are a concern at 436 NE Ivy Street, just east of the former Grant Warehouse facility. The limited monitoring conducted for this PA is insufficient to draw a conclusion that Grant Warehouse is the sole source of lead without other lines of evidence connecting the contaminants at both properties. Other properties sampled for lead were below risk based concentrations, except in areas where lead based paint may be expected, near drip lines and in close proximity to the home footprint. DEQ will contact the owner of 436 NE Ivy Street to discuss the results of the assessment and make recommendations to either remove soil or create a physical barrier to prevent direct contact with soil in locations greater than 400 mg/kg on the property.

Grant Warehouse Areawide June 20, 2013 CERCLIS No. ORSNF0012090 Page 13 7.0 AIR MIGRATION PATHWAY

7.1 Likelihood of a Release Compounds, if released, would most likely have been transported as wind borne particulates (dust) during the operation of the Grant Warehouse facility. The prevailing winter wind direction is East Southeast for Portland International Airport, approximately 3 miles to the northeast of the site; during the summer the prevailing wind direction is North Northwest (21).

7.2 Air Targets The site is considered residential properties. Small business and commercial properties align NE MLK Blvd. The nearest large scale employer is Emmanuel Hospital 0.5 mile to the southwest of the site. Albina Head Start is located 700 feet to the northeast of the site.

The population located in the vicinity of the site and surrounding area is provided below. DEQ utilized the Circular Area Profile population tool at the Missouri State Data Center (18) to determine the estimated radial population. The Circular Area Profile population tool uses the population data from the 2010 U.S. Census (6).

Radial Distance from Site Population

0 to ¼ mile 649 ¼ to ½ mile 5,790 ½ – 1 mile 17,647 1 – 2 mile 55,115 2 – 3 mile 85,739 3 – 4 mile 52,426 Total 235,013

Sensitive environments and wetlands (14) were identified for the radial distances listed below.

Radial Distance from Site Sensitive Environments and Wetlands in acres

Site none 0 to ¼ mile none ¼ to ½ mile None ½ – 1 mile none 1 – 2 mile None 2 – 3 mile 96 3 – 4 mile 273

7.3 Air Migration Pathway Conclusions Based on current site conditions, a release to the air pathway is unlikely to be detected.

Grant Warehouse Areawide June 20, 2013 CERCLIS No. ORSNF0012090 Page 14 8.0 SUMMARY AND CONCLUSIONS

The former Grant Warehouse site was used to recover precious metals from ore, liquids and process wastes from other facilities for approximately 18 years between 1980 to 1998. The site is currently vacant with residential neighborhood surrounding. Grant Warehouse received a No Further Action (NFA) determination from DEQ in July 2006, but the NFA did not include the off site residential soils which were above residential risk based concentrations for lead.

Sampling with an XRF was performed in 2013. Lead concentrations were above residential risk based concentrations at 436 NE Ivy Street, just east of the former Grant Warehouse facility. However, the limited monitoring conducted for this PA is insufficient to draw a conclusion without other lines of evidence connecting the contaminants to Grant Warehouse. Other sources of lead from leaded gasoline (high volumes of cars and large trucks), nearby historic industrial facilities in the general vicinity, and lead based paint may also have contributed to the moderate lead concentration in soil on this property. Other properties sampled for lead were below risk based concentrations, except in areas where lead based paint may be expected, near drip lines and in close proximity to the home footprint.

DEQ will contact the property owner of 436 NE Ivy Street to discuss the results of the assessment and make recommendations to either remove soil or create a physical barrier to prevent direct contact with soil in locations greater than 400 mg/kg on the property. DEQ will also send a letter to the owners of all properties monitored for this PA to inform them of the results and provide information regarding best management practices to minimize exposure to lead on their property, particularly in older homes with lead-based paint.

Page 7 of 12 Attachment B Explanation of QC Qualifier Codes

Qualifier Meaning ______B (EPA) - The indicated compound was found in the associated method blank as well as the laboratory sample. J (EPA) - Estimated value below the lowest calibration point. Confidence correlates with concentration. O (ESC) Sample diluted due to matrix interferences that impaired the ability to make an accurate analytical determination. The detection limit is elevated in order to reflect the necessary dilution. Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable "unless qualified as 'R' (Rejected)."

Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses. TIC - Tentatively Identified Compound: Compounds detected in samples that are not target compounds, internal standards, system monitoring compounds, or surrogates.

The data package includes a summary of the analytic results of the quality control samples required by the SW-846 or CWA methods. The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report.

Method Blank - an aliquot of reagent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier.

Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples.

Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier.
