11 Introduction At the request of TRUE Consulting Group (TRUE) and the District of Lillooet (DoL), Summit Environmental Consultants Inc. has provided hydrogeological services for a groundwater exploration program. This report presents the results of our investigations which were initiated in August 2010.

1.1 PROJECT BACKGROUND AND OBJECTIVES

While the District of Lililooet continues to evaluate its long term plans for primary surface water supplies, the need for additional supplemental groundwater supplies is also being addressed. If developed, new groundwater capacity would serve as a primary water source in the near term and possibly either a primary or a supplemental/backup water source in the long term.

The DoL has several wells, three of which are currently operating and supplying domestic water to residents (Conway 1, Conway 2 and Rec 2). The existing wells are characterized by moderate yields, and for parts of the year, domestic water demand exceeds the combined capacity of these wells.

We are also aware that groundwater from the deep aquifers in which two of the existing wells are completed (Conway) exhibits arsenic concentrations at or above the health-based 0.010 mg/L Maximum Allowable Concentration (MAC) set by Health Canada. With the concern for arsenic in mind, groundwater exploration efforts were directed to a finding an aquifer where arsenic concentrations were reasonably expected to be lower, such as in a shallow aquifer in direct hydraulic connection with nearby surface water.

The current groundwater exploration program focused on District owned lands along the Seton River, in the Cayoosh Creek Campground (“project site” or “site”, extent depicted in Figures 2-1 and 2-2). Prior to beginning this program, Summit assessed groundwater development potential in the Lillooet area, and recommended exploring at the project site. This recommendation was based on the site’s potential to develop high-yield groundwater wells, to source water with low arsenic concentrations, and chosen with the understanding that a groundwater source under the influence of surface water (GWUDI) would be acceptable. At the District’s request, the exploratory drilling program was expanded to include one test well at the so-called Forestry site located at the corner of Mt.View Road and Main Street, the results of which are included in Appendix F.

We understand that the DoL may be seeking grant funding to help cover the costs associated with further groundwater development (production wells) at the Cayoosh site, and for construction of the appropriate water system and treatment infrastructure. This report is intended to present the hydrogeolgocial information collected to date to support the grant application, and to provide recommendations for proceeding with source development and the eventual construction of full-size production wells.

1.2 SCOPE OF WORK

Summit’s role in the project was to design and oversee the groundwater exploration program. Summit performed the following in completing the project:

1) Met with TRUE project engineers and DoL staff to discuss the program and review what lands were available for immediate groundwater exploration. 2) Completed a background information review including previous groundwater reports, historical aerial photographs, and information about the existing DoL water system, infrastructure and water demands. Summit also searched the B.C Site registry database for information on reported nearby contaminated sites and spoke with Lillooet residents familiar with the historical land use in the area. 3) Summit hydrogeologists made a reconnaissance of potential drill sites in June 2010 and staked potential test well locations in the field. Several such locations were identified at the Cayoosh site and one location was staked at the Forestry site. 4) Coordinated with a private utility locator investigate the potential test well sites and confirm that no underground utilities were present. 5) Prepared technical specifications for test well drilling and then obtained competitive quotes from three well drillers. 6) Conducted site orientations and safety meetings with all contractors prior to commencing work. 7) Summit hydrogeologists were onsite for the five day test well program, logged subsurface stratigraphy, collected formation samples at regular intervals, and completed field sieve analysis on potential screen zones to determine the optimal screen design. In total, five boreholes were advanced and two were completed as test wells. 8) Coordinated with a test pumping contractor to complete a series of pumping tests on the test wells. Analyzed and interpreted the data collected to estimate the long-term well capacities and aquifer properties. 9) Measured field water quality parameters during pumping tests and collected several water quality samples from the well discharge for analysis at an accredited laboratory. 10) Interpreted the groundwater quality results to verify that the source was suitable for potential use as a community supply source. 11) Assessed the potential for the wells to be considered under the influence of surface water and made preliminary source protection assessment. 12) Compiled all the data collected and prepared this report to document the exploration program and support grant funding applications.

22 Well Location and Construction Information This section describes the location, hydrogeologic setting and the construction of the two test wells at Cayoosh. Appendix F provides the information on the Forestry site test well, which exhibited low potential to serve a municipal well site. Well driller logs for all boreholes and test wells are provided in Appendix B.

2.1 PHYSIOGRAPHIC SETTING

The project site is located near the confluence of the Seton and Fraser Rivers, on the north side of the Seton and on the west side of the Fraser (Figure 2-1). Regionally, the Lillooet area is located in a narrow valley bottom and is backed on all sides by steep mountain ranges. Elevation at the confluence of the Rivers is approximately 200 m asl, while peaks forming the valley sides reach 2,000 m or more. The Fraser River valley/canyon extends generally north-south and is the major control on topography in the area. The Seton River valley, extends a west from its confluence with the Fraser. The Seton River is dammed approximately 3.5 km upstream of the site at a B.C. Hydro facility to form Seton Lake. Topography at the Cayoosh Creek campground project site is relatively flat, with a gentle slope to the east.

The project site is located in a complicated area in terms of surficial geology. Ryder (1976) completed comprehensive surficial geology mapping for the Lillooet area and interpreted the history and chronology of deposition. The oldest unconsolidated sedimentary deposits present consist of glaciolacustrine silts and fine sand formed by sedimentation in a large glacially impounded lake. These fine sediments were eroded and replaced in places by pre-glacial advance outwash, which was in turn buried or eroded during glacial advance. The most recent deposits consist of late-glacial and post-glacial outwash deposits which have been locally down-cut through by the combined erosional forces of the Fraser and Seton rivers. Modern alluvial deposits are also present along the banks of the Fraser and Seton Rivers. The alluvial materials near the mouth of the Seton River may be a remnant of an alluvial / deltaic fan deposit that overlies the older glacial deposits.

Bedrock geology in the area is controlled by a series of northwest-southeast trending faults. Bedrock geology on the west side of the Fraser River consists of marine sedimentary and volcanic rocks as well as metamorphic varieties, all of the Bridge River Complex, 157 to 353 million years old (BCGS 2005).

The town core of Lillooet is located to the north and topographically above the project site. The focus of groundwater exploration, the Cayoosh Creek Campground, is a seasonal campground with capacity for approximately 25 visitors. Domestic water for the campground is supplied from a shallow dug well and sewage is handled by an onsite septic system located in the western part of the campground (Figure 6-1). Land use to the southwest along the Seton River is industrial with one periodically operating lumber and veneer mills present. Surrounding land use as well as considerations for groundwater development are discussed further in Section 6.

2.2 BOREHOLE DRILLING AND WELL COMPLETIONS

In total, five boreholes were advanced at the project site and their locations are depiction Figure 2-2. Two of the boreholes were completed as test wells, hereafter referred to as test wells 1 (WPN 29271) and 2 (WPN 29256). All drilling was carried out by J.R. Drilling Ltd. of Kamloops, B.C. (B.C. Registered Well Driller # WD06030601) between August 14-18, 2010. All boreholes were completed with the dual rotary method using a Foremost DR12 drilling rig. Boreholes and test wells were completed in the following order (refer to Figure 2-2): 1) Borehole 1 2) Test well 2 3) Borehole 2 4) Borehole 3 5) Test well 1

Summit hydrogeologists (Ryan Rhodes P.Geo and Tilman Roschinski, GIT) observed and supervised the exploratory drilling program, logged subsurface stratigraphy and collected formation samples. The stratigraphy encountered in boreholes 1 through 3 consisted predominantly of dark grey silt, fine sand and clay. While water-bearing in places, the material was not suitable for completion of a test well. These boreholes were backfilled with alternating layers of drill cuttings and bentonite chips per the requirements of the B.C Groundwater Protection Regulation. A 6.1 m (20 ft) bentonite plug was used in the upper portions of each borehole.

A clean, brown sand and gravel aquifer was encountered at the locations of test wells 1 and 2, and was judged to be of sufficient thickness and productivity to be evaluated further with well completions followed by pumping tests. Well screen design was determined based on field review of drill cuttings and sieve analysis of formation samples in the potential screen zone. Field sieve results are provided in Appendix C

Following drilling and screen installation, each well was developed for approximately 4 hours by surging and lifting water from the well using compressed air with the air-rotary rig. Construction details for both test wells as well as information on the boreholes is summarized in Table 2-1. Well drillers logs are provided in Appendix B.

2.3 HYDROGEOLOGIC SETTING

The west side of the Fraser River in the Lillooet area, including the project site, is reportedly underlain by Provincially-mapped sand and gravel aquifer 324 IIIC (MOE 2010). Aquifer 324 is classified by the B.C. Ministry of Environment as having a low demand, moderate productivity and low vulnerability to contamination. The bulk of urban development in the DoL is located on a series of benches above the Fraser River, 40 m to 100 m above the typical river stage. The DoL currently uses several groundwater supply wells on the benches which are screened at 70 m to 160 m depth, and completed in Aquifer 324, with the Conway and Well 69-1 well screens typically in the elevation range of 70 to 90 m asl. The low vulnerability classification assigned to aquifer 324 is attributed to the semi-confined or confined nature of the aquifer and the great depth below surface at which it is intercepted, rendering it relatively safe from surface-based contamination.

Borehole drilling at the project site indicates that much of the campground site is underlain by thick deposits of fine sediments (silt and fine sand). Boreholes 1, 2 and 3 encountered these deposits to depths of 24 m (80 ft) or more. A test well reportedly (Grossler, D., pers comm. 2010) drilled by Field Drilling in the 1990s (denoted as “BH-Field” on Figure 2-2) was reportedly completed to a depth of 120 m (400 ft), encountered only silt and did not intercept an aquifer. While mapped as being present at the project site, information to date indicates that aquifer 324 is not present at the Cayoosh Creek campground site, at least to the 120 m depth reportedly explored by Field, which would be approximately elevation 80 m asl, or around the mid- point of the Conway well screens. If Aquifer 324 is present beneath the Cayoosh campground site, it is either thin, or is deeper than the depth reported reached in the Field borehole.

A deep aquifer is also known to be present at depth west and upstream of the project site on the south side of the Seton River. One well registered to the Cayoosh Creek Indian Band is reportedly 120 m (395 ft) deep and sources an aquifer located in the lowest 5 m of the well. The well screen elevation of approximately 90 m asl suggests it is the same aquifer as developed at the Conway Park site in Lillooet.

The aquifer that was intercepted at the project site is relatively shallow. Test wells 1 and 2 are 15.2 m and 14.6 m (50 and 48 ft) deep respectively (at about elevation 185 m asl), and are underlain by fine grained sediment (silt, sand and clay) that is not water-bearing. The aquifer is comprised of brown sand and gravel deposits, is unconfined and believed to have a strong hydraulic connection with the Seton River. The aquifer is interpreted to be comprised of modern fluvial scour and alluvial deposits of the Seton River.

2.4 AREA GROUNDWATER USE AND NEARBY REPORTED WATER WELLS

Summit conducted a search of the B.C Ministry of Environment Water Resources Atlas (MOE 2010), which contains information on reported water wells and aquifer mapping. The search indicated that the only reported wells at the project site are the two test wells drilled for this project, and the existing dug well which supplies water to the campground.

2-6 2010-8304.020 District of Lillooet: Seton River Fan Groundwater Exploration Program TRUE Consulting Group 2 - Well Location and Construction Information

Seven other wells are reported within 500 m of the project site (Figure 2-4). Four of these wells are registered to the District of Lillooet and located in the Conway Park Area. Two of these wells are actively used by the DoL for domestic water supply (Conway 1 and Conway 2, which are 150mm and 250mm in diameter respectively), and produce approximately 500 US gpm between them.

Two of the wells are registered to the Ainsworth Lumber Company which formerly owned and operated a saw mill in the area. The saw mill has since been demolished and these wells are no longer used. Logs for these wells indicate that both are relatively shallow dug wells adjacent to the Seton River. The location of these wells is likely inaccurately portrayed on Figure 2-4.

In summary, of the reported nearby wells, only the existing campground supply well and the two Ainsworth wells (no longer in use) appear to be completed in the same aquifer as the test wells. Groundwater use in the targeted aquifer is low.

REPORT

33 Well Testing Methods Summit coordinated with a qualified test pumping contractor to complete a variety of pumping tests on both test wells at the Cayoosh Creek Campground. Well testing was completed between September 7 and 9, 2010, with follow-up testing of Well 2 completed on October 14. In both cases, the subcontractor chlorinated the tested well to 200+ ppm chlorine at least 24 hours prior to testing.

Test Well 1 (WPN 29271) Lillooet Contracting of Lillooet, B.C. (B.C. qualified well pump installer #06041901) completed test pumping of test well 1 under Summit’s supervision on September 7-8, 2010. The contractor installed a temporary 15 horsepower electric submersible pump (Franklin Motor, operated at 200 V, 54.4 A) to a depth of 11.3 m (37 ft). The pump flow rate was controlled with a valve on the discharge line, and flow was measured with an analog in-line flow meter. Water depth in the well was measured using an electric well sounder to the nearest 0.01 feet. The testing program consisted of:  A variable rate step test with 30-minute steps at rates of 3.3, 6.3 and 13.1 L/sec (52.5, 100 and 208 US gpm) followed by 30 minutes of recovery measurements.  A 24-hour constant rate pumping test at a rate of 13.1 L/sec (208 US gpm), followed by 60 minutes of recovery measurements.

The water level in well 2 (WPN 29256) was monitored at regular intervals during the test using a pressure transducer and data logger, and with a well sounder.

Tilman Roschinski, GIT of Summit measured field water quality parameters (temperature, pH, conductivity and turbidity) and collected water quality samples from sample taps on the discharge line at three times during the test. At the beginning of the constant rate pumping test and after 6 hours of pumping, a sample was collected for analysis of total metals, dissolved metals and microbial parameters. Samples were collected again near the end of the test and were analyzed for the list of parameters specified by IHA for approval of new drinking water sources, plus selected additional parameters Summit recommended to fully characterize a water source. All samples were collected into new, laboratory-supplied bottles, placed into a cooler with ice, and couriered to Caro Analytical of Kelowna, B.C

On October 14, 2010 additional samples were collected after 12 hours of pumping at an approximate rate of 200 US gpm. These samples were analyzed for selected hydrocarbon parameters and sent to Caro Analytical of Richmond, B.C. for analysis.

Water from the well was discharged approximately 120 m downslope onto a gravel-covered floodplain deposit. The water pooled and infiltrated within a 50 m radius of the discharge point. The discharge water was carefully monitored throughout the testing to ensure surface runoff did not reach the Seton River or the Fraser River.

3-1 2010-8304.020 District of Lillooet: Seton River Fan Groundwater Exploration Program TRUE Consulting Group 3 - Well Testing Methods

Test Well 2 (WPN 29256) Under Summit’s supervision, a pumping test was attempted on Well 2 on September 8, 2010. The same 15 horsepower electric submersible pump was installed to an approximate depth of 12.8 m (42 ft). Soon after pumping began, the pump seized up, was removed from the well and found to be sand-locked. The pump was re-installed and started with a similar result. A camera survey was performed on the well. It was noted that several inches of sand had accumulated in the bottom of the well, but otherwise the well casing, k- packer seal and well screen appeared to be in good condition.

JR Drilling was contacted to discuss possible causes of the sand production, and by chance happened to be working in Lillooet that day. It was decided that some additional well development was warranted, and JR Drilling re-mobilized to the site on September 9 and completed 5.5 hours of additional development. JR reported that the sand production appeared to originate in the upper portion of the screen, and the additional development was focused on that area. After several hours, sand production had not been significantly reduced and development was stopped.

The reason for the sand production is unclear. It was originally questioned whether the k-packer seal between the well casing and well screen had been compromised, however the first and a second camera survey indicated this was not the case. It is possible that a zone of finer-grained material is located just above the well screen, and was not detected during formation sampling. Formation samples were collected at 5 ft intervals during well drilling and a fine grained interval may have been missed. It should be noted that test well 1 is screened over the same interval with an identical screen slot size and a sand production problem did not occur.

Additional testing of well 2 was not attempted. The well was capped and locked. See discussion in Section 7 for recommendations on drilling another well adjacent to test well 2.

44 Well Testing Results To interpret the test pumping results, we processed raw pumping test data into a series of graphs and analyzed the data. The analysis included well and aquifer hydraulics, in order to estimate aquifer properties and to determine whether the aquifer’s productivity is sufficient for the intended use. Using provincial guidelines, we estimated the long-term sustainable capacity of test well 1. Appendix A provides the test data, graphs and interpretations.

4.1 TEST PUMPING RESULTS FOR TEST WELL 1

The results of the test pumping program on test well 1 indicated a productive well and aquifer setting. In response to each increase in flow rate, water levels quickly adjusted and nearly stabilized within minutes of the step changes (Figure A1, Appendix A). Table 4-1 summarizes the specific capacity at each pumping rate for test well 1. These values are considered good for a 150 mm well.

Following the step testing, a 24-hour constant rate test at a rate of 13 L/sec (208 US gpm) was initiated. The drawdown versus time response curve for the 24-hour constant rate test is illustrated on Figure A2. The hydrograph for the 24-hour test shows that more than 90% of the observed drawdown occurred in the first twenty minutes of the test. At the end of the test, 55% of the available drawdown had been utilized in the well. The observed well recovery was strong, with 82% recovery occurring within the first 10 minutes of the pump being shut off.

The Seton River is dammed upstream and consequently flow in the river is regulated by BC Hydro. During the pumping tests, the level of the Seton River was deliberately lowered by what visually appeared to be 0.15 m to 0.3 m (0.5 to 1 ft) over a 24-hour period near the test wells. Summit was not aware of the lowering of the Seton River and was therefore not monitoring changes in the stage of the river during test pumping of the wells.

4-1 2010-8304.020 District of Lillooet: Seton River Fan Groundwater Exploration Program TRUE Consulting Group 4 - Well Testing Results

Water level data from active provincial hydrometric station 08ME003, located on the Seton River upstream of the project site and downstream of the Seton Lake dam were obtained and depicted in Figure 4-2 (Water Survey of Canada 2010). The water level data indicates that 0.3 m of water level decline occurred at the hydrometric station. This does not correlate exactly to the water level decline that occurred in the River near the project due to differences in channel geometries, however this value agrees well with our visual observations during the test.

Figure 4-2 Raw water level data for the Seton River at hydrometric station 08ME0003

Data Source: Water Survey of Canada 2010

The implications of the lowered Seton River stage is that the ambient static water level in the aquifer was also likely declining in concert with the river due to the probable direct hydraulic connection between the shallow aquifer and the nearby river. Late time data from the constant rate test, after approximately 200 minutes on Figure A3, show a steady rate of decline which we believe is attributable to dropping river levels. If Seton River levels had not been dropping, it is likely that groundwater level stabilization or near stabilization would have been observed in both the pumping well and the observation well.

4.2 WELL INTERFERENCE

To assess the potential for well interference, water levels in Test Well 2 were monitored during the test pumping program on Test Well 1. The wells are located 32 m (105 ft) from each other. During the constant rate test, 0.32 m (1.05 ft) of potential well interference was observed. We refer to this as “potential” well

4-2 2010-8304.020 District of Lillooet: Seton River Fan Groundwater Exploration Program TRUE Consulting Group 4 - Well Testing Results

interference, because again, it is unclear how much of the drop in water levels in the monitoring well was induced by the pumping of test well 1 and how much was a result of a drop in the Seton River level. Based on the water level recovery data, it appears that approximately 1/3 of the drawdown observed (0.1 m or 0.33 ft) was a result of well interference. This level of well interference is small, and indicates that well interference should not ne a limiting factor to groundwater development if wells are spaced approximately 30 m apart.

4.3 AQUIFER PROPERTIES

Aquifer properties were estimated based on the drawdown response in test well 1 during the 24 hour constant rate test, and the Cooper-Jacob (1946) straight line method was applied. Derivative data generated from the drawdown test was used to select the portion of the drawdown curve appropriate to apply the Cooper – Jacob solution. A transmissivity value of 1,800 m2/day was calculated, which is a relatively high value. Using the static water level on Sept. 7, 2010 and the depth to the bottom of the well screen as the aquifer thickness, the hydraulic conductivity of the formation is estimated at 165 m/day. A realistic value of specific yield was not obtained.

4.4 WELL SUSTAINABALE YIELD

In keeping with Provincial guidelines, Summit estimated the sustainable yield of the test well based on the method outlined in the Certificate of Public Convenience and Necessity (CPCN) guidelines to evaluating groundwater sources for use in water utilities (Allen et al., 1999). This method uses long-term constant rate test pumping data, extrapolates the drawdown trend to a theoretical 100-day pumping water level, and applies a 70% safety factor. Summit applied this method to the constant rate test data as shown in Figure A3.

As discussed in Section 4.2, the late-time drawdown observed is likely attributable to dropping river levels. To be conservative, Summit did not make adjustments in our calculations to compensate for declining ambient groundwater levels, because declining river level will likely occur during actual well operation at the project site. The results of our calculations still indicate that the aquifer is quite productive, and that the well has a sustainable yield of 13.7 L/sec (217 US gpm).

The connection between the aquifer water levels and the stage of the Seton and Fraser Rivers will have implications for the sustainable yield of any wells completed at the project site. During runoff when water levels rise, the theoretical long-term capacity of wells in the area will increase as groundwater levels rise and the amount of available drawdown increases. The opposite will happen during low water levels.

There is a large amount of hydrometric data available for local watersheds, with active hydrometric stations on the Seton River, Cayoosh Creek and the Fraser River. A brief review of the hydrograph for the Seton River upstream of the project site, station 08ME003, (Figure 4-3) indicates that maximum discharge typically occurs in June and by September, discharge is at average levels and is declining towards seasonal lows. Further in-depth review of the Seton River hydrology is required to support design of

production wells at the site (see Recommendations), but the preliminary review of hydrology is promising because typical maximum water demands will usually occur on the municipal water system (May through September), water levels in the Seton River, and consequently the aquifer, will be at average to above average levels.

4.5 POTENTIAL FOR MUNICIPAL SCALE GROUNDWATER DEVELOPMENT

The results of the test well program indicate that additional groundwater development is possible at the site. The productivity of the aquifer, combined with the small amount of well interference observed, indicates that larger diameter production wells, with carefully engineered well screens and appropriate well development methods applied should be capable of higher sustainable yields. The amount of water produced from the test well was limited by the capacity of a submersible pump that can be installed in a 150 mm diameter well. The results of the test well program indicate that a 300 mm diameter (12-inch) production well should be capable of producing 31.5 L/sec (500 US gpm) or more. It is also likely that two production wells of this size can operate at the site simultaneously, and be spaced about 25-30 m apart

55 Water Quality 5.1 GROUNDWATER QUALITY TESTING RESULTS

A summary of the analytical results of groundwater quality testing from test well 1 is provided in Table 5.1. Three samples were collected during the test pumping program on September 7-8, 2010: 1) One sample was collected approximately one hour into the constant rate pumping test and analyzed for total metals, dissolved metals and microbiological parameters. 2) One sample was collected six hours into the constant rate pumping test and analyzed for total metals, dissolved metals and microbiological parameters. 3) One sample was collected at the end of the 24 hour constant rate test and analyzed for the complete list of parameters requested by IHA for evaluating drinking water sources.

Following 12 hours of pumping on October 14, a suite of samples was again collected from test well 1 for analysis of selected hydrocarbon parameters.

Results indicate that the water meets or surpasses the Guidelines for Canadian Drinking Water Quality (GCDWQ) (Health Canada 2008) for all parameters with health-based guidelines and aesthetic objectives. A more in-depth discussion of water quality follows, and complete laboratory water quality results are provided in Appendix D.

General Physical and Chemical Properties The groundwater chemistry of the well is characterized as a calcium-sulfate-bicarbonate type and is relatively low in total dissolved solids. Overall, the water displays a low level of mineralization.

Concentrations of anions such as fluoride, nitrate, chloride and total organic carbon are low. Concentrations for these parameters are well below their respective guidelines. With a total hardness of 81.4 mg/L the water is of medium hardness.

Microbiological Properties No Total Coliform or E. Coli organisms were found in any of the well samples collected. Non-pathogenic iron related bacteria were detected while sulfate reducing bacteria were not detected in the sample.

Hydrocarbon Parameters Samples from test well 1 were collected for analysis of Light and Heavy Extractable Petroleum Hydrocarbons, Polycyclic Aromatic Hydrocarbons and Volatile Organic Compounds. In all cases, reported concentrations for these parameters were below laboratory detection limits.

Water Treatment Characteristics Overall, the groundwater has low concentrations of total and dissolved metals parameters. The concentrations of aluminum, iron and manganese decreased over the course of pumping suggesting that

5-1 2010-8304.020 District of Lillooet: Seton River Fan Groundwater Exploration Program TRUE Consulting Group 5 - Water Quality

the well water is a mixture of true groundwater from upland areas and infiltrated surface water from the Seton River. With continued pumping, the proportion of infiltrated surface water produced by the well probably increased. Measured arsenic concentrations were detectable but an order of magnitude below the Maximum Allowable Concentration of 0.01 mg/L.

Turbidity measurements in the field indicated no turbidity in the groundwater. The laboratory measurement is reported as 0.2 NTU. UV transmittance is high (>99%), suggesting very good quality water.

5.2 GROUNDWATER-SURFACE WATER COMPARISON

To aid in a preliminary assessment of surface water influence on the well, field water quality was measured in the Seton River during the test pumping of Well 1. Salmon were spawning in the Seton River and the water was visually clear at the time of measurement. Field water quality data is summarized in Table 5-2.

Table 5-2 Comparison of Field Parameters in Surface Water and Groundwater Parameter Units Well 1 (WPN 29271) Seton River pH -log [H+] 8.12 8.12 Temperature Deg. C 13.2 13.2 Conductivity uS/cm 163 100 Turbidity NTU <0.1 0.83

Test Well 1 was approximately 25 m from the nearest point on the Seton River during the testing period. The comparison of surface water and groundwater field parameters indicates that the groundwater signature is similar to that of the surface water. Conductivity is somewhat higher in the groundwater, suggesting that the well water being discharged at the time of the testing was a mixture of true groundwater and aquifer recharge from the Seton River. The measured turbidity is lower in the groundwater than in the surface water indicating that filtration is occurring in the aquifer.

5.3 GROUNDWATER CORROSVE/ENCRUSTIVE POTENTIAL

Groundwater from the local aquifer is considered moderately hard, and has low concentrations of iron, manganese, and sulphate. Table 5.4 below summarizes selected results of the water quality testing alongside a list of parameters and concentrations developed by the National Groundwater Association, which indicate a well might have encrustive (plugging) problems. Five of six of these parameters were analyzed for and only one parameter in Test Well 1 (pH) was found in concentrations indicating encrustation potential. The presence and concentration of these parameters suggest that wells completed in the aquifer should not be prone to encrustation leading to decreases in well efficiency.

The Langelier Index is a measure of the saturation of calcium carbonate in water. Negative values for this parameter indicate corrosive water, while values greater than zero indicate a potential for calcium- carbonate deposition. The value calculated from the test well is negative and near neutral, indicating only a minor potential for corrosion.

Corrosive groundwaters are typically characterized by high or low pH values and elevated iron concentrations. The local groundwater pH is slightly basic but there is low concentrations of iron in the water. The Aggressiveness Index (AI), calculated using the parameters pH, total alkalinity and calcium hardness, is a general indicator of the tendency for corrosion to occur. AI values greater than 12, indicate a

5-3 2010-8304.020 District of Lillooet: Seton River Fan Groundwater Exploration Program TRUE Consulting Group 5 - Water Quality

low tendency for corrosion, while values of 10 to 11.9 indicate moderately aggressive water. With an AI value of 11.9 it again appears that there is only a minor potential for corrosion to occur.

The performance of the wells, as with all community supply wells, should be monitored over time.

66 GWUDI, GWAR and Source Protection Discussion The following sections address source protection considerations and assess the test well’s potential to be considered under the influence of surface water (GWUDI) or at risk (GWAR).

6.1 POTENTIAL FOR GROUNDWATER AT RISK (GWAR) AND SURFACE WATER INFLUENCE (GWUDI)

Prior to commencing the groundwater exploration project, through discussions with TRUE and the DoL, it was decided that a GWUDI groundwater source would be acceptable if DoL developed well sources at the Cayoosh site. To aid in project planning and water treatment planning, Summit assessed the potential for the test wells to be classified as Ground Water At Risk (GWAR) according to the procedures outlined in the B.C. Ministry of Environment Draft 5 - Guidance Document for Determining Ground Water at Risk of Containing Pathogens including Groundwater Under the Direct Influence of Surface Water (MOE 2009). The Ontario MOE Terms of Reference for Hydrogeological Study to Examine Groundwater Sources Potentially Under Direct Influence of Surface Water (2001), known as the Ontario GWUDI Guidelines, is a widely used tool for screening potential GWUDI sources and was also referenced.

Definitions The guidance document defines GWAR as “any groundwater supply that is susceptible to contamination from any source of pathogens and will require disinfection or other level of treatment as prescribed by the Drinking Water Officer” (MOE 2009). Potential sources of pathogens to groundwater may include sewage effluent discharge to land, agricultural waste stockpiles and surface water that is hydraulically connected to groundwater.

The guidance document defines GWUDI as “groundwater that is hydraulically connected to surface water and is susceptible to contamination from pathogens.” Although some groundwater supply sources may be hydraulically-connected to surface water, only where conditions allow microbial pathogens to freely travel from surface water to the groundwater source is there a potential threat to human health. In those cases there is incomplete or undependable subsurface filtration of surface water or infiltrating surface water. If a groundwater source is determined to be GWUDI, then the water must be treated to the same level as surface water with respect to pathogen removal and inactivation. The GWUDI potential of a well source is determined by a professional hydrogeologist who applies professional judgment.

There is some overlap between the definitions of GWAR and GWUDI, which may lead to misinterpretation. GWUDI should be considered a potential risk contributing to a well’s GWAR determination. There may be cases where a well is shown to not be GWUDI, however the well is still considered GWAR. This situation could arise where a well is not located near any surface water sources, but is situated in an unconfined aquifer near high-risk land uses such as fuelling stations or industrial parks.

6-1 2010-8304.020 District of Lillooet: Seton River Fan Groundwater Exploration Program TRUE Consulting Group 6 - GWUDI, GWAR and Source Protection Discussion

6.1.1 Preliminary GWUDI Screening

To determine whether the subject well would be ‘flagged’ as potentially GWUDI, Table 5.3 examines whether GWUDI criteria apply to the well (from Section 2.0 of the Ontario Guidelines). The following assessment applies to both test wells 1 and 2.

For the well to be flagged as a potential GWUDI source, criteria 1 or 2 would have to be applicable, and one or more of the additional criteria (2a – 2e) would also have to apply. Our hydrogeological assessment concludes that the test well meets several of the GWUDI criteria; and therefore we flag the wells as potentially GWUDI.

Because a well is flagged as potentially GWUDI, does not necessarily mean that there is unimpeded movement of surface water pathogens from nearby surface water through the aquifer and into the well. In many cases, there is sufficient subsurface filtration in the aquifer by which surface water pathogens cannot migrate. Accurate characterization of the well’s GWUDI status would require additional hydrogeologic investigation including modified microparticulate analysis, and may be desired should a decision to proceed to production wells be made. If a decision to assume the water is GWUDI is made and appropriate treatment is provided, additional investigation of GWUDI status will not be required. The very high UV transmittance is favourable for primary disinfection with ultraviolet light followed by residual chlorination, but the overall treatment method should be reviewed by a qualified professional engineer at the pre-design or design stage.

6.1.2 Source Protection Considerations

Along with assessing the test well’s potential to be GWAR, it is prudent to discuss land use in the area and potential sources of contamination near the well. Refer to Figure 6-1 for the following discussion.

The test wells are located in a small, municipally-owned campground. The campground is serviced by a seasonally-used community septic tank and dispersal field, located approximately 150 m northwest of the test wells. There is also private septic system used by the campground operator, who lives at the site year- round, located approximately 75 m northwest of the test wells. A small amount of dry, domestic waste from users of the campground is temporarily stored at the site and removed to a landfill as needed.

Summit conducted a search of the B.C. Ministry of Environment Site Registry database, which maintains records on contaminated sites, remediations and spills in B.C. Two sites are reported within 500 m of the project site (Sites ID 0009045 and 0021511). The results of the search and the detailed reports for each site are provided in Appendix E.

Both sites reported are located in same area, approximately 200 m southwest of the test wells, on the western side of Duffy Lake Road. Both of the sites are former gasoline and/or diesel fuel cardlock stations, the detailed reports for both indicate only that underground fuel storage tanks were present on both properties. Both facilities operated for many years but no evidence of the cardlock facilities is currently

6-2 2010-8304.020 District of Lillooet: Seton River Fan Groundwater Exploration Program TRUE Consulting Group 6 - GWUDI, GWAR and Source Protection Discussion

present. One long-time resident reported that one of the facilities was remediated recently (in 2010), and that all underground tanks and at least some contaminated soil was removed from the site (Grossler, D., pers. comm.. 2010). Summit attempted to contact the Ministry of Environment contacts listed on the detailed site registry reports for both sites but were not provided with any additional information.

Further to the southwest on the north side of the Seton River is the remnants of the former Ainsworth Lumber Co. sawmill. The mill was demolished several years ago, and much of the area is now vacant or used for log storage. 1.2 kilometres southwest is the Aspen Planers veneer mill. This mill was formerly owned and operated by the Ainsworth Lumber company and for many years produced veneer material for use in plywood products. The mill is currently on standby pending contract negotiations, and may reopen in the future. 300 m west and 40 m higher in elevation on the first of several benches is a large, CN Rail switching yard. This property was not listed in the B.C. Site Registry database.

6.1.3 GWAR Determination

The preliminary GWUDI screening above indicates that the well sources are flagged as possibly GWUDI, although based on the site hydrogeology, we expect that large-diameter pathogens such as Giardia or Cryptosporidium are not a high risk in these sources, which will need to be confirmed with field testing. The MOE guidance document lists several parameters to consider when assessing the GWAR status of a well, several of which are similar to those addressed in Table 5.2. Table 5.3 lists several applicable GWAR criteria from MOE 2009, as well as site specific criteria developed by Summit. Criteria previously addressed in Table 5.2 have been omitted.

The GWAR screening indicates the test wells are at a moderate risk of containing pathogens. This moderate risk is due primarily to the proximity of the wells to surface water and concerns related to the potential for the wells to be considered GWUDI. The wells are located in an area which may be prone to flooding under high water conditions, and this represents the single largest threat to production wells completed in this location. There is no government floodplain mapping for the Fraser River at Lillooet. We understand from discussions with DoL staff and others familiar with the area that lower-lying portions of the Cayoosh site can flood during high water events. This information suggests a flood risk analysis would be warranted in order to determine an appropriate well site grading plan and wellhead completion elevation should the District decide to develop production wells and other infrastructure at the site. See recommendations.

The wells are completed in an aquifer which is considered somewhat vulnerable, due to its unconfined nature and relatively shallow depth. Land use in the campground is considered low risk which bodes well for safe groundwater development. Because the property is owned by the DoL, land use in the area can be controlled, allowing for only continued low-risk activities.

Surrounding land use, in particular historic land use at two sites located 200 m to the southwest poses some risk to the aquifer. Testing of the groundwater from the test wells for potential contaminants of concern indicated that no hydrocarbon parameters assessed were found at detectable concentrations.

The greatest potential for contamination of the well source is from surface water pathogens; however it is our understanding that should production wells at this location be pursued, a water treatment plant will be constructed to treat the water as if it were surface water.

There is some land use in the area of the well site which is considered an elevated contamination risk – in particular two former bulk fuel stations located approximately 200 m southwest. The results of the test well program indicate that the aquifer is not directly connected to the lands where the former bulk fuel cardlocks were located. Testing of the groundwater for hydrocarbon parameters showed that no detectable hydrocarbons were present.

REPORT

77 Conclusions and Recommendations 7.1 CONCLUSIONS

Summit provided hydrogeological services to oversee a groundwater exploration program in a District of Lillooet-owned campground near the Seton River. Based on the results of the groundwater exploration program, Summit concludes that: 1. Five boreholes were advanced at the project site and two were converted to 150 mm diameter test wells that meet the requirements of the B.C. Groundwater Protection Regulation. The three unsuccessful boreholes were properly closed immediately after drilling. 2. The test wells are completed in an unmapped sand and gravel aquifer adjacent to the Seton River. The aquifer is unconfined and moderately productive. 3. The results of the pumping tests indicate that test well 1 can be sustainably produce 13.7 L/sec (218 US gpm). The amount of water produced from the well during testing was limited only by the capacity of the submersible pump. 4. Interpretation of test pumping data was complicated by the fact that water levels in the Seton River were dropping during the testing, and lowering water levels in the aquifer. It is possible that water level stabilization may occur with the extended pumping. 5. Pumping tests were attempted on test well 2 and were not possible because the well produced sand. Additional well development was attempted but was unsuccessful at alleviating the sand production in the test well. This site still has potential for a productive well using a different well design approach than used on the test well. 6. Well interference effects were observed between the test wells during testing, but the magnitude of interference was small (0.1 m or 0.33 ft at 208 US gpm). Well interference should not be a limiting factor to larger scale groundwater development at the site. 7. Water levels in the aquifer will respond relatively quickly to changes in water levels in the Seton River. An initial review of the Seton hydrology indicates that during times of high municipal water demand, the water level in the Seton River will typically be high, boding well for groundwater development. 8. The test well program indicates that larger-scale groundwater development at the site for municipal supply use is possible. Two, larger diameter wells capable of 31.5+ L/sec (500+ US gpm) appear feasible. 9. Groundwater quality from the aquifer was assessed and found to be of very good quality. No exceedences of health-based or aesthetic water quality guidelines were observed. 10. A preliminary assessment of the wells potential to be considered under the influence of surface water (GWUDI) indicates that the wells are likely GWUDI. 11. Summit completed a preliminary source protection appraisal and assessed the potential for the wells to be considered groundwater at risk (GWAR). The test wells are located in a seasonal

7-1 2010-8304.020 District of Lillooet: Seton River Fan Groundwater Exploration Program TRUE Consulting Group 7 - References

campground which poses only a low risk to the aquifer. The campground is owned by the DoL, so future land use in the campground can be controlled and potential sources of contamination mitigated. There is some elevated-risk land use several hundred meters southwest of the test wells (former fuel dispensing facilities). Preliminary water quality testing for contaminants of concern indicate that the aquifer sourced is not impacted by this former land-use. 12. There is an unquantified risk of flooding at the Cayoosh site including the locations of the potential production wells. No government floodplain mapping is available for the Fraser River at Lillooet. Flow in the Seton River is regulated by B.C. Hydro, but during a Fraser flood event, its level would also increase.

7.2 RECOMMENDATIONS

Should municipal-scale groundwater development be pursued at the project site, we recommend the following: 1. Complete a detailed review of the area hydrology and a flood risk analysis for the project site to identify an appropriate finished grade for wellheads and pump buildings. This assessment should be completed by a professional hydrologist (estimated cost ~$10,000) and can be conducted during the pre-design or design phase of the project. 2. Complete two, 300 mm diameter production wells adjacent to test wells 1 and 2. These wells should be drilled and developed using the cable-tool method, with hydrogeologic oversight of the drilling and screen design. Following drilling and complete well development, the wells should be test-pumped to ascertain sustainable yield and operational pumping parameters. 3. Complete a flood risk assessment of the proposed production well sites, in order to determine an appropriately safe wellhead and pump house construction elevation, so that site regarding may be incorporated into the site’s engineering design. 4. Upon successful completion of the production wells, further assessment of GWUDI can be performed if DoL requires more information in order to choose an appropriate treatment and disinfection process for its wells, including the new wells. This further assessment would consist of modified microparticulate analysis testing (at least two different tests) done during high water in late spring to mid-summer. 5. Further recommendations including cost estimates are provided in a separate memorandum.

The following section reports quality control (QC) data that is associated with your sample data. Groups of samples are prepared in “batches” and analyzed in conjunction with quality control samples that ensure your data is of the highest quality. Common QC types include:

• Method Blank (Blk): Laboratory reagent water is carried through sample preparation and analysis steps. Method Blanks indicate that results are free from contamination, i.e. not biased high from sources such as the sample container or the laboratory environment

• Duplicate (Dup): Preparation and analysis of a replicate aliquot of a sample. Duplicates provide a measure of the analytical method’s precision, i.e. how reproducible a result is. Duplicates are only reported if they are associated with your sample data.

• Blank Spike (BS): A known amount of standard is carried through sample preparation and analysis steps. Blank Spikes, also known as laboratory control samples (LCS), are prepared from a different source of standard than used for the calibration. They ensure that the calibration is acceptable (i.e. not biased high or low) and also provide a measure of the analytical method’s accuracy (i.e. closeness of the result to a target value).

• Standard Reference Material (SRM): A material of similar matrix to the samples, externally certified for the parameter(s) listed. Standard Reference Materials ensure that the preparation steps in the method are adequate to achieve acceptable recoveries of the parameter(s) tested for.

Each QC type is analyzed at a 5-10% frequency, i.e. one blank/duplicate/spike for every 10 samples. For all types of QC, the specified recovery (% Rec) and relative percent difference (RPD) limits are derived from long-term method performance averages and/or prescribed by the reference method.

CLIENT Summit Environmental Consultants Inc. WORK ORDER # R010221 PROJECT 2009-8304.010 REPORTED Oct-21-10

The following section reports quality control (QC) data that is associated with your sample data. Groups of samples are prepared in “batches” and analyzed in conjunction with quality control samples that ensure your data is of the highest quality. Common QC types include:

• Method Blank (Blk): Laboratory reagent water is carried through sample preparation and analysis steps. Method Blanks indicate that results are free from contamination, i.e. not biased high from sources such as the sample container or the laboratory environment

• Duplicate (Dup): Preparation and analysis of a replicate aliquot of a sample. Duplicates provide a measure of the analytical method’s precision, i.e. how reproducible a result is. Duplicates are only reported if they are associated with your sample data.

• Blank Spike (BS): A known amount of standard is carried through sample preparation and analysis steps. Blank Spikes, also known as laboratory control samples (LCS), are prepared from a different source of standard than used for the calibration. They ensure that the calibration is acceptable (i.e. not biased high or low) and also provide a measure of the analytical method’s accuracy (i.e. closeness of the result to a target value).

• Standard Reference Material (SRM): A material of similar matrix to the samples, externally certified for the parameter(s) listed. Standard Reference Materials ensure that the preparation steps in the method are adequate to achieve acceptable recoveries of the parameter(s) tested for.

Each QC type is analyzed at a 5-10% frequency, i.e. one blank/duplicate/spike for every 10 samples. For all types of QC, the specified recovery (% Rec) and relative percent difference (RPD) limits are derived from long-term method performance averages and/or prescribed by the reference method.

F Appendix F - Forestry Site Test Well Summary

F-1 2010-8304.020 District of Lillooet: Seton River Fan Groundwater Exploration Program November 2010 Appendix F

Appendix F - Forestry Site Test Well

In addition to the Cayoosh Creek campground wells, Summit installed and test pumped one well at the former Forestry site, owned by the District of Lillooet. The site is located on Mt. View Road at the intersection with Main Street. The test well was installed in the north-west corner of the site.

Well Construction One borehole was drilled at the site and completed as a test well. All drilling was carried out by J.R. Drilling Ltd. of Kamloops, B.C. (B.C. Registered Well Driller # WD06030601) on August 17, 2010. Well screen design was determined based on field review of drill cuttings. Four feet of 30 slot screen were installed and the well was developed for approximately four hours by surging and lifting water from the well using compressed air with the air-rotary rig. Construction details are provided below:

Well ID: WPN 29272 Diameter: 6 in / 150 mm Depth: 58 feet (17.7 m) Static Water Level: 37.2 ft (11.3 m) below top of casing Screen Slot size: 30 slot (total length of screen 4 ft or 1.2 m) Screen depth: 54 to 58 ft (16.5 to 17.7 m) below ground surface K-packer depth: 52 ft (15.8 m)

The well driller’s log is provided at the end of this appendix.

Summit hydrogeologist Tilman Roschinski, GIT observed and supervised the exploratory drilling program, logged subsurface stratigraphy and collected formation samples. The borehole was advanced to 86 feet (26 m) bgs, but casing was withdrawn to the installation depth of 58 feet and the rest of the borehole allowed to collapse in on itself. The stratigraphy encountered in the borehole consisted of sand and gravel from the surface to a depth of about 57 feet, after which the formation gradually increased in silt content. Water production decreased to a depth of 66 feet. A clayey silt layer was encountered from 66 to 86 ft bgs and did not produce any water. A bentonite surface seal was installed to a depth of 20 feet (6.1 m) in accordance with the requirements of the B.C Groundwater Protection Regulation.

Test Well Evaluation Methods Lillooet Contracting of Lillooet, B.C. (B.C. qualified well pump installer #06041901) completed test pumping of the forestry site well under Summit’s supervision on September 9-10, 2010. The contractor installed a temporary electric submersible pump to a depth of 16.2 m (53 ft). The pump flow rate was controlled with a valve on the discharge line, and flow was measured with an analog in-line flow meter. Water from the well was discharged into a storm drain approximately 40 m from the well. Water depth in the well was measured using an electric well sounder to the nearest 0.01 feet. The testing program consisted of:  A variable rate step test with 30-minute steps at rates of 0.5, 1.2 and 1.3 L/sec (7.9, 18.5 and 21.1 US gpm) followed by 40 minutes of recovery measurements.  A 24-hour constant rate pumping test at a rate of 1.5 L/sec (23.8 US gpm).

November 2010 Appendix F

Field water quality parameters (temperature, pH, conductivity and turbidity) were monitored throughout the test. Summit collected water quality samples from sample taps on the discharge line at three times during the test. At the beginning of the constant rate pumping test and after 6 hours of pumping, a sample was collected for analysis of total metals, dissolved metals and microbial parameters. Samples were collected again near the end of the test and were analyzed for the list of parameters specified by IHA for approval of new drinking water sources, plus selected additional parameters Summit recommended to fully characterize a water source. All samples were collected into new, laboratory-supplied bottles, placed into a cooler with ice, and couriered to Caro Analytical of Kelowna, B.C

Test Pumping Results The results of the test pumping program on the well (WPN 29272) indicated a moderately productive well and aquifer setting. In response to each increase in flow rate during the step test, water levels quickly adjusted and nearly stabilized within minutes of the step changes (Figure F1). Table F1 summarizes the specific capacity at each pumping rate for WPN 29272.

Following the step testing, a 24-hour constant rate test at a rate of 1.5 L/sec (23.8 US gpm) was initiated. The drawdown versus time response curve for the 24-hour constant rate test is illustrated on Figure F2. The hydrograph for the 24-hour test shows that more than 90% of the observed drawdown occurred in the first ten minutes of the test. However, 210 minutes into the test, the water level started to rise (see Figure F3), most likely in response to the shutting off of a nearby irrigation well (reported capacity 50 US gpm). This complicates an accurate estimate of the well’s long-term capacity using the CPCN guideline but using professional judgment, Summit estimates the long-term capacity of the well to be 15 to 20 US gpm. The observed well recovery was strong, with 82% recovery occurring within the first 10 minutes of the pump being shut off.

Table F1 – Pumping Test Summary WPN 29272 (Forestry site well) Total Depth (ft below TOC) 58 Static Water Level (ft below TOC) 37.2 Step Test Specific Capacity % drawdown Pumping Rate (US gpm) Drawdown (ft) (US gpm/ft) used 7.9 2.57 3.07 11% 18.5 8.15 2.27 36% 21.1 11.5 1.83 50% 24-hour Test 23.8 13.1 1.81 57%

Water Quality Three water quality samples were collected during the test pumping program on September 9-10, 2010: 1) One sample was collected approximately one hour into the constant rate pumping test and analyzed for total metals, dissolved metals and microbiological parameters. 2) One sample was collected six hours into the constant rate pumping test and analyzed for total metals, dissolved metals and microbiological parameters. November 2010 Appendix F

3) One sample was collected at the end of the 24 hour constant rate test and analyzed for the complete list of parameters requested by IHA for evaluating drinking water sources.

Results indicate that the water meets or surpasses the Guidelines for Canadian Drinking Water Quality (GCDWQ) (Health Canada 2008) for all parameters with health-based guidelines and aesthetic objectives. Complete laboratory water quality results can be found at the end of this appendix.

General Physical and Chemical Properties The groundwater chemistry of the well is characterized as a calcium-magnesium-bicarbonate type and has a moderate level of mineralization. Concentrations of anions such as fluoride, nitrate, chloride and total organic carbon are low. However, nitrate concentrations at 1.17 mg/L indicate an anthropogenic influence. Concentrations for these parameters are well below their respective guidelines. With a total hardness of 273 mg/L the water is considered very hard.

Microbiological Properties No Total Coliform or E. Coli organisms were found in any of the well samples collected. Non- pathogenic iron related bacteria were detected while sulfate reducing bacteria were not detected in the sample.

CLIENT Summit Environmental Consultants Inc. WORK ORDER # K0I0426 PROJECT Approval of New Sources-IHA (Geller) REPORTED Sep-22-10

The following section reports quality control (QC) data that is associated with your sample data. Groups of samples are prepared in “batches” and analyzed in conjunction with quality control samples that ensure your data is of the highest quality. Common QC types include:

• Method Blank (Blk): Laboratory reagent water is carried through sample preparation and analysis steps. Method Blanks indicate that results are free from contamination, i.e. not biased high from sources such as the sample container or the laboratory environment

• Duplicate (Dup): Preparation and analysis of a replicate aliquot of a sample. Duplicates provide a measure of the analytical method’s precision, i.e. how reproducible a result is. Duplicates are only reported if they are associated with your sample data.

• Blank Spike (BS): A known amount of standard is carried through sample preparation and analysis steps. Blank Spikes, also known as laboratory control samples (LCS), are prepared from a different source of standard than used for the calibration. They ensure that the calibration is acceptable (i.e. not biased high or low) and also provide a measure of the analytical method’s accuracy (i.e. closeness of the result to a target value).

• Standard Reference Material (SRM): A material of similar matrix to the samples, externally certified for the parameter(s) listed. Standard Reference Materials ensure that the preparation steps in the method are adequate to achieve acceptable recoveries of the parameter(s) tested for.

Each QC type is analyzed at a 5-10% frequency, i.e. one blank/duplicate/spike for every 10 samples. For all types of QC, the specified recovery (% Rec) and relative percent difference (RPD) limits are derived from long-term method performance averages and/or prescribed by the reference method.
