2 2012 ANNUAL OPERATIONS AND MONITORING REPORT Executive Summary An annual operations and monitoring report for the Westside Landfill is required under the Operational Certificate (OC) PR#12217 issued by British Columbia Ministry of Environment (MoE). This report presents the results of groundwater and landfill gas monitoring completed for The Westside Landfill was closed in July 2010, and therefore no waste was accepted in The final cap elevation will be below the original design elevation, and final surface grading is being designed as part of the landfill closure plan. The results of the 2012 monitoring program at the Westside Landfill are summarized below: The groundwater sampling and analysis indicated that wells located near the landfill footprint (BH1, BH2 and BH4) had certain parameters that exceeded the provincial Contaminated Sites Regulation (CSR) standards for drinking water use, including chloride, magnesium and manganese. There are no known drinking water wells nearby and the municipal water is sourced from Power Creek, located several kilometres upslope from the landfill. The two wells located further downgradient but within 50 to 300 metres of the landfill (BH3 and BH5) did not exceed the CSR groundwater standards. No groundwater parameters exceeded the CSR standards for aquatic life. Similar to historical groundwater quality results, monitoring wells BH1, BH2, and BH4 showed elevated concentrations of several parameters relative to historical background concentrations (Dobbin s Well). Concentrations of these indicator parameters remained relatively constant during the 2012 monitoring program. An upward trend for sodium and chloride concentrations has been observed at downgradient well BH5 between 2005 and These parameters are currently below CSR standards at BH5, and concentrations of these parameters near the landfill boundary appear steady or show a slight downward trend. Methane concentrations at the landfill gas monitoring probes were similar to During the five gas monitoring events, only three of the 37 probes had at least one methane reading above 1% LEL (lower explosive limit). Only one probe (BH102) had a methane reading above 12% LEL. Methane readings at BH102 have historically been high, and in 2012 methane concentrations of 100% LEL were measured on three occasions, and a non-detectable measurement (<1% LEL) was recorded at BH102 in the summer (July 2012). Under the new Landfill Gas Management Plan (Golder, 2013), gas probe BH102 is considered a midboundary probe, located about 30 m inside the east property line. Because the methane levels at BH102 were historically above 25% LEL, nearby probes gas probes were installed in 2007 along the east property boundary. The three near-boundary probes in the vicinity of BH102 are consistently below 1% LEL, which indicates that the elevated methane at BH102 is bounded within the site boundaries, as required in the Landfill Gas Management Plan. It is recommended that a specific action plan (SAP) be developed for BH102, to address the consistently high methane readings at that location. Other landfill gas parameters, such as hydrogen sulphide and carbon monoxide, remain low at all of the gas monitoring location. April 22, 2013 Report No Rev i

3 2012 ANNUAL OPERATIONS AND MONITORING REPORT Based on the 2012 monitoring results, Golder recommends that the landfill gas monitoring be carried out as described in the Landfill Gas Management Plan (Golder, 2013). It is recommended that groundwater monitoring be conducted as outlined in the draft closure plan. The frequency of long-term monitoring will be reviewed at the end of In the short-term, the high methane concentrations at BH102 have been bounded within the site, as required in the new Landfill Gas Management Plan. However, it is recommended that a specific action plan (SAP) be developed to address the consistently high methane readings at that location. April 22, 2013 Report No Rev ii

6 2012 ANNUAL OPERATIONS AND MONITORING REPORT 1.0 INTRODUCTION An annual operations and monitoring report for the Westside Landfill has historically been prepared under Operational Certificate (OC) PR#12217 issued by British Columbia Ministry of Environment (MoE). The Regional District of Central Okanagan (RDCO) closed the Westside Landfill (the Site) in July 2010 and did not accept any new waste material in 2011 or Consequently, information related to the landfill operations is not included in the 2012 report, but is covered in previous Golder reports. The following information is included in this report: Operational (closure) plan and budget; Upgrades to existing monitoring infrastructure; and, Groundwater and landfill gas monitoring data and interpretation. A location plan and site plan for the Westside Landfill are presented as Figures 1 and 2, respectively. 2.0 MUNICIPAL AND SOLID WASTE MEASUREMENT 2.1 Waste Tonnages No waste was accepted by the Westside Landfill in Waste Volumes and Density A discussion on the waste volume estimates and survey information is provided in the 2010 Annual Operations and Monitoring Report (Golder, 2011). 2.3 Service Population and Waste Discharge Rates A discussion on the per capita generation rates is provided in the 2010 Annual Operations and Monitoring Report (Golder, 2011). 2.4 Design Volume and Remaining Capacity Historical survey information and lifespan estimates are provided in the 2010 Annual Operations and Monitoring Report (Golder, 2011). Based on recent survey data obtained by the RDCO, the final cap elevation will be below the original design elevation. Final surface grading is being designed as part of the landfill closure plan.

7 2012 ANNUAL OPERATIONS AND MONITORING REPORT 3.0 CLOSURE PLANS AND BUDGETS 3.1 Closure Plan and Related Reports The closure of the Westside Landfill by the RDCO involves preparation of a final Closure Plan. Preparation of the Westside Landfill closure plan was initially completed in September The RDCO retained CH2M Hill to prepare an updated closure plan for the Westside Landfill. A draft Closure Plan was issued in August 2011, and forwarded to MoE for review. Golder has prepared the following two documents that expand on the draft Closure Plan: Landfill Gas Management Plan, Westside Landfill, dated January 24, Options for Final Cover Systems, Westside Landfill, dated September 19, The above reports were initially submitted as draft to RDCO and the Ministry of Environment (MoE), and have since been finalized based on their input. 3.2 Landfill Closure and Monitoring Budget A summary of estimated costs for landfill closure and ongoing monitoring was developed as part of the draft Closure Plan. The estimated costs have been revised based on the additional details for the landfill cover design and ongoing gas management that are provided in the reports listed in Section 3.1. The estimated remaining landfill closure budget is $340,000. The estimated annual post-closure monitoring costs are $45,000. A cost breakdown by item is presented in Table UPGRADES TO MONITORING INFRASTRUCTURE An additional soil vapour probe (VP12-01) was drilled and installed on the Site to aid in soil vapour monitoring on the southeastern portion of the landfill. The probe was installed on April 24, 2012 at the location shown on Figure 3. The probe was installed to a depth of approximately 1.7 metres below ground surface (m bgs) with a 1 metre long screen (0.75 to 1.7 metres). Soil conditions at that location included silty sand to approximately 1.37 m bgs, underlain by fractured bedrock to approximately 1.52 m bgs, followed by competent bedrock to a final drilled depth of 1.7 m bgs. The borehole log is enclosed in Appendix A. 5.0 GROUNDWATER AND LANDFILL GAS MONITORING The purpose of the groundwater and landfill gas monitoring program is to monitor the potential impacts that the landfill may have on the local groundwater quality and to assess the potential for landfill gas migration.

8 2012 ANNUAL OPERATIONS AND MONITORING REPORT 5.1 Monitoring Scope and Frequency The draft Closure Plan (CH2M Hill, 2011) outlines a two-year monitoring program for landfill gas. The frequency of gas monitoring was increased slightly in the Landfill Management Plan (Golder, 2013). Landfill gas monitoring was completed on a quarterly basis in 2012, with two monitoring rounds completed in the winter (November and December 2012). The monitoring program going forwards will adopt the Landfill Management Plan and then be evaluated after the first two years. The current groundwater monitoring program is based on the draft Closure Plan. In 2012, the frequency of groundwater monitoring was reduced to semi-annually in order to increase the level of gas monitoring in A review of historical groundwater results indicated that at each well, concentrations of individual parameters fall within a relatively steady range. Consequently, long-term trends will be measured with two samples in the year. Quarterly groundwater sampling will be resumed in 2013 and then reviewed at the end of the year, as recommended in the draft Closure Plan. 5.2 Regulatory Framework The BC MoE Contaminated Sites Regulation ([CSR] April 1997, amendments to January 24, 2013) is the principal document for the evaluation of the environmental quality of groundwater in British Columbia. The standards listed in the CSR provide numerical concentrations for the evaluation of groundwater quality and identify remedial requirements. Groundwater results were compared to the CSR Schedule 6: Generic Numerical Water Standards and Schedule 10: Generic Numeric Soil and Water. The CSR water standards are divided into four categories based on water use: Irrigation (IW), Livestock (LW), Drinking Water (DW), and Aquatic Life (AW). Based on previous reports, the direction of groundwater flow across the Site is inferred to be south to southwest. Potential receptors to groundwater leaving the Site include Shannon Lake, the nearest surface water body to support aquatic life, which is located at a distance of approximately 300 metres downgradient of the Site. Future drinking water use was applied as per MoE Technical Guidance 6. Consequently, the two CSR water standards compared to groundwater chemistry results were AW and DW. 5.3 Methodology Groundwater Monitoring The 2012 groundwater monitoring program for the Westside Landfill was carried out by members of Golder s technical staff. Groundwater samples collected from the wells during the 2012 monitoring program were submitted to Caro Environmental Services of Kelowna, BC (Caro) for chemical analyses. Samples were analyzed for several or all of the following inorganic parameters: ph, conductivity, total dissolved solids, hardness, alkalinity, chloride, sulphate, ammonia nitrogen, nitrate nitrogen, nitrate plus nitrite, and dissolved metals. In the past, the Dobbin s Well was used to represent background groundwater conditions, however, it is no longer accessible, so no samples could be collected. The 2005 monitoring results will be used for background comparison purposes. Monitoring wells BH1, BH2, BH3, BH4, and BH5 represent downgradient groundwater conditions. April 22, 2013 Report No Rev

9 2012 ANNUAL OPERATIONS AND MONITORING REPORT 5.4 Soil Vapour Monitoring The 2012 soil vapour monitoring program was conducted by Golder staff on January 20-21, May 7-9, July 16-18, November 13-14, and December 18-19, The locations monitored for vapours are shown in Figure 3. Landfill gases were measured using a Landtech GEM and an RKI Eagle combustible gas monitor. These instruments contain a mechanical pump which is used in conjunction with a hand operated pump to purge the gas from the monitoring wells and vapour probes until desired well/probe volumes are purged and maximum concentrations are recorded. Each instrument was calibrated prior to use at the site to one or all of the following calibration gases; methane (CH 4 ), hydrogen sulphide (H 2 S), carbon monoxide (CO), oxygen (O 2 ), and carbon dioxide (CO 2 ). 5.5 Groundwater Monitoring Results Groundwater monitoring results are discussed below. The Dobbin s Well has been used in the past to represent background groundwater conditions, and monitoring wells BH1, BH2, BH3, BH4, and BH5 represent downgradient groundwater conditions Groundwater Elevation Data The groundwater levels measured between 1994 and 2012 are presented in Table 3, and the 2012 elevations are plotted on Figure 2. Groundwater elevations show seasonal fluctuations but are otherwise relatively consistent. During the 2012 monitoring program, water levels were measured in some or all of the following wells: BH1, BH2, BH3, BH4, BH5, and BH7 during the April 2012, and January 2013 monitoring events. In general, the 2012 groundwater elevation data is consistent with previous groundwater elevation data. Based on the groundwater elevations measured in 2012 and the general topography of the area, it is inferred that groundwater flows in an east to southeastern direction at the northeast portion of the site and in a southeastern direction at the southern portion of the site, as shown on Figure 2. This is consistent with previous monitoring results. 5.6 Groundwater Quality The analytical results for samples collected in 2012 are presented in Table 4 (General Groundwater Chemistry). Historical groundwater trends for various analytical parameters are included in Appendix B. The Caro laboratory reports are included as Appendix C Background Wells Based on information provided by the owner of Dobbin s Well, the well was disconnected in 2006 due to a pipeline rupture, and the property is currently being supplied by the Westbank Irrigation District. The chemical data for the background well (Dobbin s Well) was relatively consistent over the eleven monitoring events April 22, 2013 Report No Rev

10 2012 ANNUAL OPERATIONS AND MONITORING REPORT conducted from 1994 through to Therefore, 2005 monitoring results will be used as representative background conditions. Concentrations of the indicator parameters for 2005 were generally low or below laboratory method detection limits (MDL) at Dobbin s Well with no parameters above the CSR numerical standards Landfill Monitoring Wells Compared to Background Similar to previous monitoring results, local groundwater quality has been impacted by the landfill. In the monitoring wells listed below, the following parameters were elevated above background concentrations for either one or all sampling events: BH1: Conductivity, TDS, alkalinity, chloride, sulphate, ammonia, aluminum, barium, boron, calcium, cobalt, copper, iron, magnesium, manganese, nickel, potassium, silicon, sodium, strontium, and uranium. BH2: Conductivity, TDS, alkalinity, chloride, sulphate, ammonia, boron, calcium, cobalt, iron, magnesium, manganese, nickel, potassium, silicon, sodium, strontium, and uranium. BH3: Conductivity, TDS, alkalinity, chloride, sulphate, ammonia, boron, calcium, iron, magnesium, manganese, potassium, and uranium. BH4: Conductivity, TDS, alkalinity, chloride, sulphate, ammonia, aluminum, barium, boron, calcium, cobalt, magnesium, manganese, nickel, potassium, sodium, strontium, and uranium. BH5: Conductivity, TDS, alkalinity, chloride, sulphate, boron, calcium, magnesium, manganese, potassium, and uranium. The 2012 results showed groundwater concentrations were most elevated in monitoring wells BH1, BH2, and BH4, which is similar to previous years. Groundwater parameter concentrations have generally decreased in 2012 compared to Groundwater from monitoring wells BH3 and BH5 exhibited concentrations moderately above background concentrations Monitoring Results Relative to Standards The following list presents the parameters that exceeded the CSR DW standard at one or more sampling events during the 2012 monitoring program at specific monitoring locations: BH1: chloride, magnesium, and manganese. BH2: chloride, magnesium, and manganese. BH4: chloride, magnesium, manganese and uranium. BH3 and BH5: No CSR exceedences. There were no parameters exceeding the CSR standard for groundwater flowing to aquatic life. Note that the drinking water standard for chloride is for aesthetic purposes and is not human health based. April 22, 2013 Report No Rev

11 2012 ANNUAL OPERATIONS AND MONITORING REPORT Monitoring Results Relative to Historical Data (trend analyses) For reference purposes, trend analysis graphs from 1994 through to 2012 are presented in Appendix A. Concentrations of the various analyzed inorganic parameters in groundwater collected from BH1, BH2, and BH4 all showed marked increases between 1994 and Since 1998, concentrations of most analyzed parameters from these three monitoring wells have only shown slight fluctuations and for most parameters, appear to have reached a relatively steady state. With the exception of increased nitrite plus nitrate concentrations between 2005 and 2009, concentrations of indicator parameters at BH5 have not shown significant increases between 1994 and 2012, but rather appear to have remained relatively consistent at low concentrations (with minor fluctuations) for this time period. 5.7 Landfill Gas Monitoring Results The 2012 soil vapour monitoring program was conducted by Golder on January 20-21, May 7-9, July 16-18, November 13-14, and December 18-19, 2012 at the following monitoring wells and vapour probes: Monitoring Wells: MW99-2, MW99-3, MW99-4, BH1, BH2, BH101 (shallow/deep), BH102, BH103, and MW Vapour Probes: VP07-1S, VP07-1D, VP07-2, VP07-3, VP07-5, VP07-8, VP07-9, VP07-11, VP07-12, VP07-13, VP07-14, VP07-15, VP07-16, VP07-18, VP07-19, VP07-20, VP11-01, VP11-02, VP11-03, VP11-04, VP11-05, VP11-06, VP11-07, VP11-08, VP11-09, VP11-10, and VP Soil vapour readings are presented in Table 2 (attached) and summarized below. Historical soil gas monitoring results are included in Appendix D. Combustible Gas Methane - Methane concentrations were measured using a RKI Eagle combustible gas meter. It should be noted that concentrations less than 40 parts per million (ppm) are considered representative of background conditions for this instrument. In general, methane concentrations ranged from 0 parts per million (various probes and multiple events) to 50,000+ ppm (BH102) during the May 2012 monitoring event. A summary of minimum and maximum methane concentrations is presented below. Monitoring Event Minimum Concentration Methane (CH 4 ) (ppm) Location Maximum Concentration Methane (CH 4 ) (ppm) Location January 2012 <50 Multiple locations 18,000 BH102 May 2012 <50 Multiple locations 50,000+ BH102 July 2012 <50 Multiple locations 1100 VP11-09 November 2012 <50 Multiple locations 37,000+ BH102 December 2012 <50 Multiple locations 37,000+ BH102 April 22, 2013 Report No Rev

12 2012 ANNUAL OPERATIONS AND MONITORING REPORT Oxygen - Oxygen concentrations were measured using a Landtec GEM2000 combustible gas meter with concentrations ranging from 2.8% at BH101 (deep) to near atmospheric level of 21.9% at VP Minimum and maximum oxygen concentrations are summarized in the table below. Monitoring Event Minimum Concentration Oxygen (O 2 ) (%) Location Maximum Concentration Oxygen (O 2 ) (%) Location January BH VP11-09 May BH101D 21.3 VP07-09, VP07-20 July VP VP07-18, VP07-20 November BH VP11-10 December BH VP11-06 Carbon Monoxide Carbon monoxide was measured using a Landtec GEM2000 combustible gas meter with concentrations of 0 ppm during the January, May, July, and November 2012 monitoring events. Carbon monoxide was not measured during the December 2012 event. Carbon Dioxide - Carbon dioxide was measured using a Landtec GEM2000 combustible gas meter with concentrations ranging from 0.0% at VP07-20 to 26.9% (BH102) during the December 2012 monitoring event. A summary of maximum and minimum concentrations of carbon dioxide is below. Monitoring Event Minimum Concentration Carbon dioxide (CO 2 ) (%) Location Maximum Concentration Carbon dioxide (CO 2 ) (%) Location January VP BH102 May VP07-9, VP BH102 July VP BH2 November VP BH102 December VP BH102 Hydrogen Sulphide Consistent with previous monitoring events, concentrations of H 2 S were 0 ppm in all wells during the January, May, June and November 2012 monitoring events. Hydrogen sulphide was not measured during the December 2012 monitoring event. 5.8 Quality Assurance / Quality Control To ensure that the sampling and analytical data were interpretable, meaningful, and reproducible, conformance to a Golder Quality Assurance and Quality Control (QA/QC) program was followed. This involved using QA/QC measures in both the collection (field program) and analysis (laboratory) of environmental samples. The following discussion includes a brief summary of the QA/QC measures implemented by Golder during the April 22, 2013 Report No Rev

13 2012 ANNUAL OPERATIONS AND MONITORING REPORT field program and during our review of the data, as well as the QA/QC measures implemented by the analytical laboratory. Quality Control (QC) measures used in the collection, preservation, and delivery of samples included the following measures: Sampling methods were consistent with established Golder protocols and provincial/federal requirements; Field notes were recorded during all stages of the investigation and are available upon request; and, Samples were subsequently transported to the laboratory using Golder and laboratory chain of custody procedures. Copies of the chain-of-custody forms are provided in Appendix B. The Quality Assurance (QA) measures established for the field program included: Submission of blind field duplicate samples for a minimum of 10% of the samples analyzed. A blind field duplicate sample is a second sample of a certain media (e.g., water) from the same location that is submitted to the analytical lab under a separate label. The relative percent difference (RPD) between field duplicate sample results was used to assess duplicate sample data. The RPD is a measure of the variability between two outcomes from the same procedure or process and is calculated by ( x x ) 1 2 absolute 100 ( 1, 2 ) average x x where x 1 is the original sample result and x 2 is the blind field duplicate result. In general, the RPD should not be more than 30%. A RPD greater than 30% may reflect within jar variability (which reflects the nature of the contaminant distribution) or variation in the test procedures. If analytical results are within five times the laboratory detection limit for the parameter, then calculation of a RPD is not a valid means of assessing laboratory bias. The following Data Quality Objectives were established for the laboratory program: The chemical laboratory that was used must have achieved proficiency certification by the Canadian Association for Laboratory Accreditation (CALA) for the analyses conducted. Caro performed all the chemical analysis of the water samples for this investigation. Caro is certified by CALA for all analytical methods used for this program. Each Caro batch includes at least one analytical blank, one laboratory duplicate sample, and one reference sample, as required by the data quality objectives. All reports from the labs are internally reviewed prior to submission to Golder. If any internal QA/QC problems are encountered, the field samples and internal QA/QC samples are re-analysed. No samples were re-analysed for this field investigation. The results are included in the analytical laboratory reports, provided in Appendix A. April 22, 2013 Report No Rev

14 2012 ANNUAL OPERATIONS AND MONITORING REPORT 5.9 Results of QA/QC A total of two duplicate water samples were collected during the 2012 Monitoring program, one for each sampling event. The duplicate water samples collected during the April 2012 and January 2013 events were labelled BHA and were duplicates from samples collected from monitoring well BH1. All samples were analyzed for ph, conductivity, total dissolved solids, hardness, alkalinity, chloride, sulphate, ammonia nitrogen, nitrate nitrogen, nitrate plus nitrite, and dissolved metals to determine any laboratory bias. This satisfies the 10% target for duplicate samples. Results for the duplicate samples collected during the 2012 monitoring events are presented in Table 5 and were generally similar (less than 30% RPD values) to that of the duplicate samples with the exception of sulfur concentrations with an RPD of % during the April 2012 event. The overall difference in concentrations for this duplicate pair was 15 mg/l. As sulfur does not have a standard, these results are considered acceptable for the purposes of the monitoring program. 6.0 DISCUSSION OF GROUNDWATER AND LANDFILL GAS MONITORING The results of the 2012 monitoring program at the Westside landfill are summarized below: The groundwater sampling and analysis indicated that wells located near the landfill footprint (BH1, BH2 and BH4) had certain parameters that exceeded the provincial Contaminated Sites Regulation (CSR) standards for drinking water use, including chloride, magnesium and manganese. There are no known drinking water wells nearby and the municipal water is sourced from Power Creek, located several kilometres upslope from the landfill. The two wells located further downgradient but within 50 to 300 metres of the landfill (BH3 and BH5) did not exceed the CSR groundwater standards. No groundwater parameters exceeded the CSR standards for aquatic life. Similar to historical groundwater quality results, monitoring wells BH1, BH2, and BH4 showed elevated concentrations of several parameters relative to historical background concentrations (Dobbin s Well). Concentrations of these indicator parameters remained relatively constant during the 2012 monitoring program. An upward trend for sodium and chloride concentrations has been observed at downgradient well BH5 between 2005 and These parameters are currently below CSR standards at BH5, and concentrations of these parameters near the landfill boundary appear steady or show a slight downward trend. Methane concentrations at the landfill gas monitoring probes were similar to During the five gas monitoring events, only three of the 37 probes had at least one methane reading above 1% LEL (lower explosive limit). Only one probe (BH102) had a methane reading above 12% LEL. Methane readings at BH102 have historically been high, and in 2012 methane concentrations of 100% LEL were measured on three occasions, and a non-detectable measurement (<1% LEL) was recorded at BH102 in the summer (July 2012). Under the new Landfill Gas Management Plan (Golder, 2013), gas probe BH102 is considered a midboundary probe, located about 30 m inside the east property line. Because the methane levels at BH102 were historically above 25% LEL, nearby probes gas probes were installed in 2007 along the east property April 22, 2013 Report No Rev

15 2012 ANNUAL OPERATIONS AND MONITORING REPORT boundary. The three near-boundary probes in the vicinity of BH102 are consistently below 1% LEL, which indicates that the elevated methane at BH102 is bounded within the site boundaries, as required in the Landfill Gas Management Plan. Other landfill gas parameters, such as hydrogen sulphide and carbon monoxide, remain low at all of the gas monitoring location. 7.0 RECOMMENDATIONS Based on the 2012 monitoring results, Golder recommends that the landfill gas monitoring be carried out as described in the Landfill Gas Management Plan (Golder, 2013). It is recommended that groundwater monitoring be conducted as outlined in the draft closure plan. The frequency of long-term monitoring will be reviewed at the end of In the short-term, the high methane concentrations at BH102 have been bounded within the site, as required in the new Landfill Gas Management Plan. However, it is recommended that a specific action plan (SAP) be developed to address the consistently high methane readings at that location. 8.0 REFERENCES Golder, Options for Final Cover Systems, Westside Landfill, dated September 19, Golder, Landfill Gas Management Plan, Westside Landfill, dated January 24, LIMITATIONS AND USE OF REPORT This report was prepared for the exclusive use of Regional District of the Central Okanagan.

46 QUALITY CONTROL DATA REPORTED TO PROJECT Regional District of Central Okanagan Westside Landfill & Shannon Lake WORK ORDER REPORTED Jan The following section displays the quality control (QC) data that is associated with your sample data. Groups of samples are prepared in batches and analyzed in conjunction with QC 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. 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.

61 QUALITY CONTROL DATA CLIENT Regional District of Central Okanagan WORK ORDER # K2D0578 PROJECT Westside Landfill & Shannon Lake REPORTED Apr 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.
