March 2016 1 CSRD – Annual Environmental Monitoring Report – Sicamous Landfill 14-024-14
1. INTRODUCTION AND SITE BACKGROUND Western Water Associates Limited (WWAL) was retained by the Columbia Shuswap Regional District (CSRD) to prepare the 2015 Annual Environmental Monitoring Report for the Sicamous Refuse Disposal Facility (RDF) (hereinafter called the “site”) as part of a district-wide monitoring contract. This report presents the monitoring for the 2015 report period from January 1 to December 31, 2015. Associated Engineering (formerly Summit Environmental Consultants Inc.) previously reported on the 2008 to 2013 monitoring programs. Prior to 2008, Sperling Hansen Associates (SHA) prepared the annual reports (SHA 2008). In 2014 WWAL was awarded the monitoring contract and we are pleased to provide the results of the environmental monitoring program at the Sicamous RDF in this report.
The Sicamous RDF was operated as a natural attenuation site by the Sicamous Waterworks District from 1971 to 1977 under Ministry of Environment (MoE), Land and Parks under permit PR 514. The site has been operated by the Columbia Shuswap Regional District (CSRD) since it was transferred in 1977 under the now referenced Operational Certificate (OC) MR-00514, issued August 23, 1971 and most recently amended December 21, 2007, by the British Columbia MoE. According to the OC, the Design and Operations Plan was prepared by Gartner Lee in 2006. The Sicamous watershed includes the municipality of Sicamous and surrounding areas, which has a permanent population of approximately 4,000 (2,441 in Sicamous alone; StatsCan 2011). This number increases to approximately 10,000 during summer as a result of tourism and seasonal residents (SHA 2008). This report was prepared in accordance with the annual landfill reporting requirements outlined in Section 4.4 of the OC. A copy of the OC is included in Appendix A.
1.1 Objective and Scope To meet the goal of assessing the long-term monitoring for groundwater impacts from landfill operations, the objectives of the program are to collect and analyze groundwater samples, and interpret analytical results in accordance with the OC (MoE 1996) and the consulting agreement between WWAL and the CSRD. The tasks undertaken were as follows:
Collect and submit to the laboratory, water samples as scheduled for the year; Assess the condition of local on-site vegetation for potential stress; Summarize water quality guideline exceedances from the 2015 results; Analyze the data and prepare the final annual report (this document); and Review the results with the CSRD Project Manager at the end of each year and provide recommendations to revise the program for future years, if warranted.
2. SITE DESCRIPTION This section describes geographic location, bedrock and surficial geology of the study area, historical climate data, hydrologic data, and hydrogeology data for Sicamous RDF. Further, a description of the monitoring network that was sampled in the 2015 monitoring program is provided.

March 2016 2 CSRD – Annual Environmental Monitoring Report – Sicamous Landfill 14-024-14
2.1 Location The Sicamous RDF is located approximately 3 km south of the intersection of Highway 1 and Highway 97A in Sicamous. The RDF is located on a hill side approximately 400 m east of Mara Lake on Two Mile Road, which branches east off Highway 97 A (Figure 1). The legal and civic address for the site are as follows:
Legal: Block A of Section 30, Township 21, Range 7, West of the Sixth Meridian, Kamloops Division Yale District.
Civic: 950 Two Mile Road, Sicamous, B.C.
The site is bounded by forest to the north, east, and west. Two Mile Road is located at the southern entrance of the RDF and provincially owned crown land extends approximately 150 m south of the RDF site. Just south, beyond the crown land, is a privately owned property that extends down to Highway 97A, is owned by Waterways Houseboats. The Sicamous RDF site is estimated to comprise an area of 4.1 hectares (10.2 acres). The site layout is provided on Figure 2. 2.2 Geology, Hydrology and Hydrogeology The regional geology and hydrogeology of the area was summarized by Kala in 1997 and SHA (2008). The Sicamous RDF is situated in a bedrock-confined gully, which acts as a tributary to the larger Sicamous Creek valley. The catchment area for this gully is relatively small at approximately 32 hectares (79.1 acres) (Kala 1997). The site is located on a thick glacial kame terrace overlying metamorphic bedrock. The terrace is comprised of glaciofluvial sands, gravels, and cobbles, which is approximately 14 m thick on the north end of the site, and is expected to be more than 60 m thick on the south side (SHA 2008). This is further evidenced by test pit logs performed on site (Kala 1997). Bedrock was encountered at 13.8 m below ground surface (bgs) at the top/northern edge of the site where monitoring well TH-2 was drilled and at 22.3 m bgs approximately 200 m southeast of the site where MW-4S and 4D were drilled. No Bedrock was encountered while drilling either TH-1, MW-3, or MW15-05; however, large boulders were encountered between 5 - 15 m bgs while drilling MW15-05.
Sicamous is located within the South Thompson River watershed. Sicamous Creek is approximately 200 m southeast of the RDF and flows along the bottom of a v-shaped valley. The valley bottom lies approximately 100 m lower in elevation than the landfill. The valley widens out near the mouth of Sicamous Creek into a floodplain before discharging to Mara Lake, which is approximately 400 m west of the RDF site. Mara Lake has one primary inflow and one primary outflow. The inflow is Shuswap River, located at the south end of the lake and the outflow is the Sicamous Narrows, which is a narrow stretch of lake connecting Mara Lake to Shuswap Lake at the north end.
The B.C. Water Resources Atlas shows MoE sand and gravel Aquifer 309 IIA approximately 300 m southwest of the Sicamous RDF. This aquifer, which is classified as having a moderate demand, moderate productivity, and moderate vulnerability, covers an area of 305,998 m2 bordering Mara Lake. Demand describes local reliance on the groundwater water source, productivity indicates relative well yields, and

March 2016 3 CSRD – Annual Environmental Monitoring Report – Sicamous Landfill 14-024-14 vulnerability describes the potential for contaminants to move from the surface into the aquifer. Based on site topography and water level elevations in the monitoring wells, groundwater flow direction at the site is from northeast to southwest, moving from the uplands towards Sicamous Creek and Mara Lake. The more regional groundwater flow will occur towards the north, based on flow of Mara Lake, which drains into Shuswap Lake at Sicamous.
No surface water ponding was evident on the landfill site or at any of the well locations. Rain and snowmelt percolating through the landfill will likely migrate vertically down until reaching the water table. Kala performed a falling and rising head slug test on TH-1 after well installation. Based on the results, Kala estimated the hydraulic conductivity at 2.7 x 10-5 m/s, which is consistent with published values for clean sand to silty sand (Freeze and Cherry 1979). WWAL also performed falling and rising head slug testing (slug and bail testing) on the newly drilled monitoring well MW15-05 (see Appendix E for discussion on slug test method and results). The estimated hydraulic conductivity is 2 x10-3 m/s, which is consistent with sand and gravel deposits. A bedrock ridge separates Sicamous Creek from the landfill, and therefore prevents surface water influence from Sicamous Creek on the groundwater monitoring wells. The depth to groundwater at the landfill is estimated to be approximately 30 m, with a gradient greater than 0.05 m/m (GLL 2006). Kala (1997) estimated a groundwater travel time of 2 to 4 years for the water to reach the lower aquifer (309 IIA).
2.3 Climate and Water Balance Sicamous is situated within a transition zone between the Okanagan Valley to the south with a semi-arid climate, and the moist Monashee Mountains to the north and east. The nearest climatic data available for the region is from the station at Sicamous (Climate STN ID 1167275). Climate averages for this station are available for 1954 to 1979. During this period, the recorded average annual temperature and total precipitation at Sicamous were 7.7°C and 657 mm/year, respectively (Environment Canada 2015). Recorded mean monthly temperatures ranged from - 5.0°C in January to 19.2°C in July. The recorded mean precipitation ranged from 27 mm/month in April to 74 mm/month in December.
The most recent climatic data available for the region is from the station at the Salmon Arm Airport (Climate STN ID 1166R45), approximately 25 km southwest of the site. Climate averages for this station are available for 1983 to 2007. During this period, the recorded average annual temperature and total precipitation for the Salmon Arm Airport were 7.4°C and 653.0 mm/year, respectively (Environment Canada 2015). Recorded mean monthly temperatures ranged from -3.7°C in January and December to 19.1°C in July. The recorded mean monthly precipitation ranged from 33.9 mm in February to 82.4 mm in November. Table 1 summarizes the climate data from the Salmon Arm Airport climate station.

In the 2000 Design and Operations Plan, Gartner Lee Limited (GLL) used two different models to calculate the water balance for the site: Thornthwaite method and HELP Model. The Thornthwaite method predicted that approximately 23% of the annual precipitation would percolate into the ground, while the HELP Model predicted the percolation rate to be 31% of the total precipitation (SHA 2008). Based on the water balance calculations made in SHA 2008, a 90 mm surplus of annual moisture, with the majority of the surplus occurring during winter, may contribute to leachate production at the site. Furthermore, because the majority of precipitation falls as snow and the ground is often frozen during the winter months, the total amount of moisture that can infiltrate into the soils is low and most infiltration is likely to occur during freshet in March and April.
2.4 2015 Monitoring Network The 2015 monitoring network included four locations: three previously monitored wells (MW-3, MW-4S and MW-4D) along with a newly installed monitoring well MW15-05 (Figure 2). Previously monitored locations include monitoring wells TH-2, TH-1, SW-1, and domestic well DMW-1. TH-2 has been dry since installation and is no longer part of the monitoring program at the Sicamous RDF. SW-1 (Sicamous Creek) has not been sampled since 2011 because prior data were deemed sufficient to establish background surface water conditions and the existing monitoring wells provide better data for tracking groundwater quality changes prior to discharge into Sicamous Creek. TH-1 and DMW-1 have not been sampled since early 2012 when they were buried by wood waste among other debris related to the flooding of Sicamous Creek. An attempt by WWAL to locate TH-1 with a pin locator was unsuccessful.
In April 2015 WWAL oversaw the drilling of an alternate monitoring well (MW15-05), approximately 100 m southeast of the original TH-1 site as a replacement for the buried well (Figure 2). MW15-05 was incorporated into the 2015 monitoring program and will continue to be monitored in the future. The newly drilled well was developed and hydraulic aquifer testing was performed. Results of the testing are outlined in the section 2.2 of this report and a well log is included in Appendix B.
Historically, DMW-1 was sampled as a background monitoring well (representing ambient water quality), and was located approximately 420 m southeast of the site. In 2012, Summit found that DMW-1 was strongly influenced by surface water and was completed within a different aquifer, and therefore was not

March 2016 5 CSRD – Annual Environmental Monitoring Report – Sicamous Landfill 14-024-14 an ideal background location. In 2015, WWAL attempted to locate suitable alternate background wells based on information gathered on the B.C. Water Resource Atlas. Three wells (Well Tag No. 32686, 22761 and 31406) were identified as a potential background locations based on well depths (MoE 2015). Attempts to contact the well owners were made during the 2015 site visits; however, they were unsuccessful. In May and August 2015, WWAL field staff surveyed the wells along the south side of Graham Road in an attempt to find a new background well. The majority of the homes were on a community supply sourced from Mara Lake. One home had a decommissioned shallow well and through conversation with the Sicamous Creek Mobile Home Park manager, the well in-use is over 243 m deep. As of yet, no new background wells have been sampled. In 2016, WWAL will continue to seek out an appropriate background well.
In April 2009, monitoring wells MW-3, MW-4S, and MW-4D were installed at the Sicamous RDF. Monitoring well MW-3 is located near the RDF front gate and monitoring wells MW-4S (shallow) and MW-4D (deep) are nested piezometers located along the west side of Two Mile Road. Table 2 summarizes the monitoring locations and well installation details. Available well logs are included in Appendix B.
Prior to 2011, sampling was conducted quarterly, with the exception of 2002 where three sampling events occurred. Beginning in 2011, the monitoring program went to tri-annual monitoring based on statistical analysis of variance (ANOVA) performed by Summit (Summit 2010). The tri-annual monitoring at the site was approved by the MoE. Sampling at Sicamous RDF occurs three times annually with the 2015 sampling events occurring on May 7, August 13, and November 17.

3. METHODS The following sections outline the program methods, including parameters sampled and field techniques used for the program. 3.1 Sampling Methods and Protocols In order to ensure that representative groundwater samples were obtained from the monitoring wells and that no contamination of the recovered samples occurred, sampling protocols followed the second edition (draft) of the “Landfill Criteria for Municipal Solid Waste” (MoE 2013), “British Columbia Field Sampling Manual for Continuous Monitoring plus the Collection for, Air-Emission, Water, Wastewater, Soil, Sediment, and Biological Samples” (MoE 2003).
Prior to groundwater sample collection, each well was purged of the standing volume of stagnant water using a submersible well pump, dedicated bailers, peristaltic pump or Waterra tubing (as appropriate). The objective of purging is to pump groundwater from the well until a representative sample of the formation groundwater is obtained. This is typically achieved by removal of three to five times the volume of standing water in the well or purging the well dry and letting the well recover to at least half of its pre-pumping level. Purging was considered complete once sediment-free groundwater is obtained and/or the EC, temperature, ORP and pH of the groundwater stabilize. The pump was decontaminated between each sample location. Groundwater samples were collected in the appropriate laboratory-supplied clean, new sample containers and preserved as required. Groundwater samples designated for metals analysis were field filtered to 0.45 micron and preserved. All samples were packaged in a cooler and delivered to the laboratory within a 24-hour period for analysis. Groundwater samples were submitted, under chain-of-custody protocol, to Caro Analytical Services (Kelowna, BC), for analysis. The laboratory results were sent directly from the laboratory to Wireless Water, our database manager. The field and laboratory data were then merged and the data were available in one database for analysis by WWAL. During each monitoring event, the following field data were recorded: water level; field measured parameters [temperature, pH, ORP, DO, and EC]; field notes on procedures (e.g. purging rates) and any unusual observations (e.g. well condition, odours, colours, etc.); evaluation of vegetation health in the area surround the wells that could be attributed to landfill leachate (luxuriant growth, discolouration, die-off, etc.); and signs of leachate breakout zones (e.g. presence of unusual bacteria or algae at all sites, signs of liquid flowing from the surface).
The quality assurance and quality control values for Sicamous are similar to past years’ RPD (relative percent difference) at less than 25%.

March 2016 7 CSRD – Annual Environmental Monitoring Report – Sicamous Landfill 14-024-14
3.2 Sampling Parameters The program remained as per 2014. The 2015 laboratory assessed water quality parameters included the following:
Total Alkalinity (total as CaCO3); pH and Conductivity
Hardness (dissolved, as CaCO3); Total and Dissolved Organic Carbon (TOC and DOC); Anions (chloride and sulphate); Biochemical oxygen demand (BOD); Nutrients: (nitrate (as N), nitrite (as N), and ammonia (as N), phosphorus(dissolved), and potassium (dissolved)); Volatile organic compounds (VOC’s) once per year; and Dissolved Metals.
The groundwater monitoring program conducted in 2015 consisted of hydraulic (water level) monitoring, field measurements of pH, electrical conductivity (EC), temperature, and oxidation-reduction potential (ORP) and dissolved oxygen (DO) recorded during purging and immediately before sampling. All of the above-listed parameters were analyzed during each sample event, with the exception of VOCs, which are only sampled once annually.
4. RESULTS AND DISCUSSION The following section describes field observations and the results of the water quality sampled at the site in 2015. Annual water level elevations, water quality guideline exceedances in 2015, along with temporal and spatial trends for the Sicamous RDF monitoring program are discussed. The descriptive statistics (average, maximum, minimum and count) for select water quality results between 2002 and 2015 are summarized in Table 4 with the full water quality database for all historic and current results provided in Appendix C. The 2015 analytical reports provided by the laboratory can be found in Appendix D.
Our analysis of potential landfill leachate impacts on the receiving environment employs two main approaches:
A direct comparison of monitoring results to guidelines (i.e. does a problem exist); and A trend analysis (i.e. is the situation changing over time or space, and if so, in what direction).
The ensuing evaluation, elucidated in our discussion below, may then be used to inform decisions about future monitoring priorities, as well as the overall program results. Water quality results were assessed both temporally and spatially.
Potential impacts to groundwater from landfill leachate are typically identified by assessing the concentrations of landfill leachate indicators relative to background groundwater concentrations. Typical leachate indicators may include, but are not limited to, ammonia, chloride, total alkalinity, sulphate,

Figures 4 through 8 depict the time series plots for 10 water quality parameters sampled at the four locations as well as at previously monitored TH-1, DMW-1, and SW-1 between 2002 and 2015. The landfill leachate associated parameters plotted include the following: chloride, electrical conductivity (EC), sulphate, nitrate, dissolved sodium, dissolved Iron, dissolved manganese, and dissolved uranium. Plotted results below the reportable detection limit are displayed as one-half the reportable detection limit.
Chloride and Conductivity (Figure 4); Dissolved Sodium and Sulphate (Figure 5); Nitrate and Ammonia (Figure 6); Dissolved Iron and Dissolved Manganese (Figure 7); and Uranium (Figure 8).
4.1 Vegetation WWAL’s assessment indicated that there is no perceived stress or health concerns for the vegetation near the Sicamous RDF. Further, there were no signs of leachate breakout zones at any of the monitored locations.
4.2 Water Level Measurements Water table elevations were relatively stable between 2009 to 2013; however, in 2014 and 2015 seasonal water levels are higher than the four previous years; with the 2015 peak slightly below 2014 (Figure 3). Further, the seasonal trend is similar throughout the data set with higher water level elevations in May and lowest elevations in November (Figure 3). Water level fluctuates between 2 m and 4 m at all monitored wells, which is consistent with seasonal variations in groundwater levels observed elsewhere in the area. We take water level elevations at newly drilled well MW15-05 to be a continuation of those measured at buried well TH-1, based on the wells proximity to each other (approximately 100 m apart), and similar completion depths (about 20 m) within the unconsolidated aquifer. The water level elevation is highest at upgradient well MW-3 and lowest at the downgradient wells MW-4S, MW-4D, and at the new well MW15-05. Based on the differences in groundwater elevationat the wells, groundwater flow direction is southwest, towards Sicamous Creek and Mara Lake.

4.3 Water Quality Exceedances Assessing impact on the receiving environment from landfill leachate is the objective of the current monitoring program at Sicamous. Due to the proximity of domestic water wells and surface water bodies in the vicinity of the site the 2015 water quality results were compared to the following applicable guidelines and standards:
Guidelines for Canadian Drinking Water Quality Maximum Acceptable Concentration (health- based guideline) (GCDWQ MAC) and Aesthetic Objective (based on aesthetic considerations) (GCDWQ AO) (Health Canada 2014); B.C. Approved Water Quality Guidelines for Drinking Water (BCAWQG DW) (MoE 2015); British Columbia Approved Water Quality Guidelines for Aquatic Life (BCAWQG AL) and Working Water Quality Guidelines for Aquatic Life (BCWWQG AL) (MoE 2015); and B.C. Contaminated Sites Regulation 375/96, Schedule 6, Generic Numerical Water Standards for Drinking Water (CSR DW) and Aquatic Life (CSR AW) (MoE 1997).
Table 3 provides a list of exceedances in water quality guidelines. Exceedances in the provincial freshwater aquatic life guidelines at the groundwater monitoring locations are listed on Table 3; however, exceedances of these parameters are not considered relevant in the current water quality assessment as the BCAWQG AL and BCWWQG AL are intended to be applied to surface waters not groundwater. Further, note that BCAWQG DW guideline applies to drinking water that is treated with chlorine to address health issues related to production of haloforms (MoE 2001). Since none of the monitoring wells are treated with chlorine the BCAWQG DW guidelines are not readily applicable to the wells at the site.

The number of water quality exceedances have decreased at monitored locations MW-3, MW-4D, and MW-4S from previous years. Similar to 2014, uranium, manganese, and total organic carbon at MW-3 and pH at MW-4S and MW-4D have all remained in exceedance. However, uranium did not exceed GCDWQ MAC and BC CSR DW guidelines at MW-3 in 2015, which is the first time it has been below these guidelines since 2009, when it was installed. Further, temperature and total organic carbon (TOC) did not exceed federal and provincial guidelines at MW-4S and aluminum, iron, and chromium did not exceed guidelines at MW-4D. The elevated concentrations of manganese and uranium are potentially due to the operation of the landfill; however, a comparable background well is needed to confirm. Exceedances at the new monitoring well MW15-05 include field measured pH (GCDWQ AO and BCAWQG DW) and dissolved oxygen (BCAWQG AL) and dissolved uranium (BCWWQG AL).
4.4 Water Quality Trend Analysis from 2002 to 2015 Sample locations were selected to monitor potential receptors surrounding the Sicamous RDF. MW-3 monitors potential impacts from the landfilling operations offsite, directly to the southeast, and MW-4D and MW-4S monitor off site receptors south of the landfill. MW15-05 replaced TH-1, which monitors potential impacts downgradient (southwest of the RDF) near developed areas. Based on drill logs, MW- 4S (shallow) monitors an upper, unconfined sand and gravel aquifer and MW-4D (deep) monitors a lower confined sand aquifer. Monitoring well TH-1 (buried) and domestic well DMW-1 have not been sampled since early 2012; however, the past results from these wells are still considered to provide valuable information for spatial comparisons of groundwater chemistry. Therefore, for the following discussion,

Overall, MW-3 continues to exhibit the highest degree of landfill leachate impact, with elevated average conductivity and concentrations of manganese, iron, sodium, sulphate, ammonia, and uranium relative to other sampling locations and relative to prior background measurements (DMW-1). However, many of the leachate-associated parameters sulphate, sodium, chloride, iron, manganese, uranium, and conductivity show decreasing trends at this location. MW-4D and to a lesser extent MW-4S exhibit slightly elevated concentrations of chloride, sodium, sulphate and conductivity, which suggests leachate impact at these locations as well, but to a lesser extent than MW-3.

March 2016 13 CSRD – Annual Environmental Monitoring Report – Sicamous Landfill 14-024-14
Chloride Historically, chloride concentrations at background well DMW-1 have been low, at around 1 mg/l, which is far below all other monitoring locations, and similar to historic surface water results (Appendix C). Chloride concentrations at monitored locations MW-4D and MW-3 are highest at the site with averages of 103 mg/l and 84 mg/l, respectively while concentrations at MW-4S are lowest with an average of 32 mg/l (Table 4). Concentrations at MW15-05 show a similar trend and level to those found at MW-3 (Figure 4). Chloride at MW-4S has remained relatively stable, whereas MW-3 shows a decreasing trend from 113 mg/l in September 2012 to 55.2 mg/l in November 2015. Concentrations at monitoring well MW-4D are variable. The trend increased from 65 mg/l in June 2009, peaked in November 2012 at 187 mg/l and has since been decreasing to 82.3 mg/l in November 2015. Furthermore, the apparent seasonal effects evident over the past five years at MW-4D (concentrations lowest in May) do not continue in 2015, with May 2015 having the highest concentration compared to the August and November sampling events.
The increases in chloride occurring at MW-4D may indicate that the lower aquifer is not truly confined, but rather a leaky aquifer. The trace gravel noted in the well log for MW-4D (between 29 and 35 m bgs) is at a similar depth to the higher conductive sand horizon found at MW-3, suggesting a preferential flow path may exist. Because chloride is a conservative ion, it may travel farther than some other landfill leachate associated parameters, such as metals that may undergo sorption or retardation due to biological or geochemical process.
Electrical Conductivity Electrical conductivity is slightly elevated at all monitored locations at the site, with the exception of historic results at DMW-1, which were around 114 µS/cm. EC levels at MW-3 remain higher (average 1194 µS/cm) than at the other monitored locations; followed by MW-4D, MW15-05, and finally MW-4S with averages of 713 µS/cm, 684 µS/cm, and 596 µS/cm respectively (Figure 4 and Table 4). EC values at MW-4D and MW-4S are relatively stable with a slight increase in levels occurring between 2011 and 2013. However, MW-3 levels are variable with a range from 148 µS/cm to 1790 µS/cm and showing a slight decreasing trend from 2011 to present. Of note, on three occasions August 2010, May 2012 and August 2014 (every two years) a large drop and subsequent increase (by an order of magnitude) in conductivity was observed. These water quality results demonstrate the seasonal and inter-annual variability of groundwater affected by natural attenuation landfill sites.
Sodium Similar to conductivity, elevated concentrations of sodium (Figure 5) at the Sicamous RDF were detected at MW-3 with moderate concentrations found at MW-4D, MW15-05, and MW-4S with the lowest concentrations historically found at DMW-1. Sodium concentrations at MW-4S have been relatively stable at approximately 16 mg/l; however, MW-4D has shown an increasing trend from about 18 mg/l in April 2011 to 41.7 mg/l in May 2015. As expected, sodium concentrations at MW-3 follow a similar trend to conductivity with a slight decrease since 2011 from 87 mg/l to 49 mg/l in November 2015.

March 2016 14 CSRD – Annual Environmental Monitoring Report – Sicamous Landfill 14-024-14
Sulphate Concentrations of sulphate at MW-3 are elevated, averaging 69 mg/l (between 2002 and 2015), well above all other monitored locations at the site and previously monitored background location DMW-1 (around 6 mg/l) (see Table 4). There also appears to be a decreasing trend in sulphate concentration, from 90 mg/l in February 2010 to 59 mg/l November 2015 at MW-3. Sulphate concentrations at monitored location MW-4S and MW15-05 are similar and are elevated above the deeper MW-4D location with averages of 33 mg/l, 31 mg/l, and 20 mg/l, respectively. Furthermore, sulphate at MW-4S is more variable than at MW- 4D with a range of 33.5 mg/l (Table 4). Landfill leachate processes may liberate sulphate from soil and other media, which would then dissolve into groundwater, resulting in elevated sulphate concentrations downgradient of the landfill. Elevated concentrations of sulphate are observed near the landfill toe, with decreasing amounts further downgradient, it is likely that landfill leachate is influencing sulphate concentrations off-site.
Nitrate and Ammonia Ammonia and nitrate concentrations at the Sicamous site are low relative to other RDF sites monitoring in the CSRD. Ammonia concentrations (Figure 6) have remained higher at MW-3 than at other monitoring locations and show a slight increasing trend from 0.18 mg/l in June 2009 to 0.55 mg/l in November 2015. Of note, an anomalous decrease (<0.02 mg/l) in ammonia concentration was observed in August 2014 at this location. There have also been significant decreases with subsequent increases in November 2012 and August 2015. In contrast, all other monitored locations show average ammonia concentrations below 0.04 mg/l with the new monitoring well MW15-05 <0.02 mg/l throughout all sampling events in 2015.
Nitrate concentrations are relatively low at all monitored locations at the Sicamous RDF, all below 3 mg/l. Nitrate concentrations (Figure 6) show the opposite pattern to that of ammonia, with higher concentrations at MW-4S, MW-4D, and MW15-05, and lower concentrations at MW-3. Nitrate at MW- 4S and MW-4D have decreased since 2011 but have remained relatively stable since 2012 at about 1 mg/l. Nitrate at MW-3 has been low and stable throughout the dataset analyzed.
As noted, MW-3 shows high concentrations of ammonia and low concentrations of nitrate while downgradient wells MW15-05, MW-4S, and MW-4D have lower concentrations of ammonia and higher concentrations of nitrate. Through nitrification, a process performed by bacteria living in the soil, ammonia is converted into nitrite then nitrate (nitrogen cycle) as a product of oxidation processes. The observed pattern of ammonia, likely present as a result of landfill activities, and nitrate at upgradient well MW-3 and downgradient wells MW-4S, MW-4D, and MW15-05 suggests that leachate impacts, which are already evident at MW-3, may be reaching downgradient locations.
Dissolved Metals Similar to other parameters, many dissolved metals are elevated at MW-3 compared to the other sampling locations and are likely related to landfill influence. However, a new background monitoring location needs to be established in order to fully understand the source of the parameters.

Iron concentrations (Figure 7) have decreased overall at all monitoring locations since 2010. Iron concentrations at MW-3 peaked in August 2010 (just below 0.7 mg/l), but have typically decreased since that time. Concentrations have been below federal guidelines since April 2011, but remain higher than at all other sampling locations. Concentrations at the other monitoring wells (MW-4S, MW-4D, and MW15- 05) remained below 0.02 mg/l in 2015.
Manganese concentrations (Figure 7) at MW-3 continued to be elevated well above (more than two orders of magnitude) all other monitored locations in 2015. Concentrations are variable at this location ranging from 0.014 mg/l (August 2014) to 1.6 mg/l (April 2011). Manganese has been stable and low at MW-4S and MW-4D since 2010 with average concentrations below 0.06 mg/l. Average concentration at the new monitoring well MW15-05 is less than 0.0057 mg/l. MW-3 may be exhibiting potential residual effects of reducing conditions, which are typical in the presence of landfill leachate. Such reducing conditions further stimulate anaerobic microbiological processes, including solubilization of iron and manganese. This conclusion is supported by the fact that iron concentrations peaked first (2010) at MW-3, followed by manganese concentrations (2011). Typically, when landfill leachate is present, iron reduction occurs first, followed by manganese reduction (Christensen et al. 2001).
Concentrations of uranium (Figure 8) at MW-3 are typically an order of magnitude greater than those at other sampled locations. In 2015, this trend continues, with the exception of August 2015, when concentrations were 0.00731 mg/l, slightly lower than MW15-05 (0.00812 mg/l) during the same sampling event. Typically, concentrations at this location exhibit an increase from November to May (the next year) and the same seasonal trend was noted in 2015. This trend is likely related to landfill influence. MW15-05 and historical well TH-1 show the next highest uranium concentrations, followed by MW-4D and MW- 4S with averages of approximately 0.008 mg/l, 0.006 mg/l, 0.004 mg/l, and 0.003 mg/l, respectively. All four of these wells exhibit stables uranium concentrations over time. Historically, the lowest values have been detected at domestic well DMW-1 (0.00004 mg/l).
The differences in levels of iron and manganese at upgradient versus downgradient locations, combined with the typically elevated concentration of uranium and other dissolved metals, suggest that the elevated iron, manganese, and uranium at monitoring location MW-3 and to a lesser extent MW-4D, MW-4S, and MW15-05 may indicate landfill leachate impacts to groundwater.
5. CONCLUSIONS From the results of the 2015 monitoring program the following conclusions are provided:
C1 Four monitoring wells were sampled in 2015; MW-3, MW4S, MW-4D, and newly drilled well MW15-05.
C2 Several landfill leachate-associated parameters are elevated at MW-3 above the further down gradient locations MW15-05, MW-4S and MW-4D. Elevated parameters include sodium, sulphate, iron, manganese, uranium, conductivity, and alkalinity, among others. These elevated parameters

suggest that MW-3 is seeing some impact due to landfill operations; however, relative to other natural attenuation landfill sites within the CSRD, the concentrations of landfill associated parameters are relatively low. Due to the location of the well (furthest from developed areas and nearest the landfill), it is unlikely that the observed impact to groundwater is caused by source(s) other than the Sicamous landfill.
C3 The number of water quality exceedances in 2015 decreased from the 2014 sampling events. Cadmium, aluminum, temperature, and iron did not exceed guidelines at any of the monitored locations in 2015. There was still a number of exceedances of federal and provincial drinking water and aquatic life guidelines in 2015 including parameters uranium, manganese, TOC, and pH.
C4 Attempts were made in 2015 to locate an existing, relevant background well, which exhibits ambient groundwater quality; however, no such well was found. Comparing water quality results to background is vital in assessing the actual impact from the landfill.
6. RECOMMENDATIONS Based on the results of the monitoring program, the following recommendations are provided:
R1 DMW-1 was originally intended to be used as a background well, but was found to be influenced by Sicamous Creek and therefore not representative of background groundwater quality in the area. The B.C. Water Resource Atlas was searched for an alternate background location, and three potential locations were identified based on depth (moderately shallow) and position relative to landfill and development. Based on these findings, we recommend that further attempts to contact the well owners be made in 2016. If permission is secured, one of the three wells should be added as the background well to monitor ambient groundwater conditions.
R2 Consistent with results from previous years, monitoring wells MW-3, and to a lesser extent MW4S, MW-4D, and MW15-05 continue to show impacts from landfill operations. Continue to monitor the offsite monitoring wells to assess the relative impact over time.
R3 Similar to the previous year’s recommendations, based on the above conclusions and that water quality exceedances linked with landfill operations are apparent in offsite wells, leachate management control measures may be required. We recommend that CSRD continue communicating with the MoE regarding leachate management measures.
R4 Building on R1, consider completing a background groundwater quality study to develop "specified water quality criteria" that can be approved by the Director to replace BC water quality guidelines. This generally involves collecting samples from three unaffected wells and completing statistical

analyses. Where collective background data fall within a single statistical population, the representative local background concentration is the 95th percentile concentration of the data set (MWLAP 2004).

Guideline Notes for Reports for CSRD Refuse Disposal Sites Water Quality Results
1. Notes for BC Approved Water Quality Guidelines for freshwater aquatic life (BCAWQG AL) General Notes: The Water Quality Guidelines (Criteria) Reports by BC Ministry of Environment were used as references for the guidelines. (Internet address: http://www.env.gov.bc.ca/wat/wq/wq_guidelines.html ). Overview Reports (BC MOE) were used as the references for the guidelines unless the note for specific analyte indicates that the Technical Appendix (BC MOE) was used. / For some parameters, guidelines are specified as two values: the maximum value or the acute criterion, and the 30- day average value or the chronic criterion. The maximum value was used in this report for parameters that have both guideline values. Note 1.1 for Dissolved oxygen: The instantaneous minimum guideline for dissolved oxygen is 5 mg/L for all life stages other than buried embryo/alevin. The instantaneous minimum guideline for dissolved oxygen in the water column is 9 mg/L for buried embryo/alevin. The instantaneous minimum guideline for dissolved oxygen in interstitial water is 6 mg/L for buried embryo/alevin. The 30-day mean guideline (minimum) for dissolved oxygen is 8 mg/L for all life stages other than buried embryo/alevin. The 30-day mean guideline (minimum) for dissolved oxygen in the water column is 11 mg/L for buried embryo/alevin. The 30-day mean guideline (minimum) for dissolved oxygen in interstitial water is 8 mg/L for buried embryo/alevin. Note 1.2 for pH: pH less than 6.5: No statistically significant decrease in pH from background. pH from 6.5 to 9.0: Unrestricted change permitted within this range. pH over 9.0: No statistically significant increase in pH from background. See BC MOE Overview Report for additional details. Note 1.3 for Temperature: The maximum daily temperature of 19 degrees Celsius is for streams with unknown fish distribution. See BC MOE Overview Report for additional details for streams with unknown fish distribution, and specific guidelines for streams with known fish distribution, and guideline for lakes and impoundments. Note 1.4 for Chloride: To protect freshwater aquatic life from acute and lethal effects, the maximum concentration of chloride (mg/L as NaCl) at any time should not exceed 600 mg/L. To protect freshwater aquatic life from chronic effects, the average (arithmetic mean computed from five weekly samples collected over a 30-day period) concentration of chloride (mg/L as NaCl) should not exceed 150 mg/L. Note 1.5 for Dissolved organic carbon: Recommended guideline for dissolved organic carbon (DOC) is 30-day median ± 20% of the median background concentration. Note 1.6 for pH: pH less than 6.5: No statistically significant decrease in pH from background. pH from 6.5 to 9.0: Unrestricted change permitted within this range. pH over 9.0: No statistically significant increase in pH from background. See BC MOE Overview Report for additional details. Note 1.7 for Sulphate: The approved 30-day average (minimum of 5 evenly-spaced samples collected in 30 days) water quality guidelines to protect aquatic life in BC for sulphate are: 128 mg/L at hardness of 0 to 30 mg/L as CaCO3 218 mg/L at hardness of 31 to 75 mg/L as CaCO3 309 mg/L at hardness of 76 to 180mg/L as CaCO3 429 mg/L at hardness 181 to 250 mg/L as CaCO3 Need to determine guideline based on site water for hardness greater than 250 mg/L as CaCO3. For screening purposes in this report, exceedance were flagged for sulphate greater than 429 mg/L at hardness greater than 250 mg/L as CaCO3. Note 1.8 for Total organic carbon: Recommended guideline for total organic carbon (TOC) is 30-day median ± 20% of the median background concentration.
Note 1.9 for Total suspended solids: Maximum Induced Suspended Sediments - mg/L or % of background: - 25 mg/L in 24 hours when background is less than or equal to 25; - Mean of 5 mg/L in 30 days when background is less than or equal to 25; - 25 mg/L when background is between 25 and 250; - 10% when background is greater than or equal to 250. / There are two refuse disposal sites (Revelstoke and Skimikin) where up gradient and down gradient samples have been collected in one water body; therefore, this guideline applies to Revelstoke and Skimikin only. Note 1.10 for Turbidity:
WW Sicamous Final Report 2015 Guideline Notes Page 1 of 13 Sicamous Refuse Disposal Site Water Quality Results
When background is less than or equal to 8 NTU: - Maximum Induced Turbidity of 8 NTU in 24 hours. - For sediment inputs that last between 24 hours and 30 days (daily sampling preferred) the mean turbidity should not exceed background by more than 2 NTU. Maximum Induced Turbidity of 5 NTU when background is between 8 and 50 NTU. Maximum Induced Turbidity of 10% when background is greater than 50 NTU. / There are two refuse disposal sites (Revelstoke and Skimikin) where up gradient and down gradient samples have been collected in one water body; therefore, this guideline applies to Revelstoke and Skimikin only. Note 1.11 for Aluminum (dissolved): The maximum concentration of dissolved aluminum at any time should not exceed: 1. 0.10 mg/L when the pH is greater than or equal to 6.5 2. The value (in mg/L) determined by the following relationship if pH less than 6.5 Dissolved Aluminum = e (1.209-2.426 (pH) + 0.286 (pH)²) The 30-day average concentration of dissolved aluminum (based on a minimum of 5 approximately weekly samples) should not exceed: 1. 0.05 mg/L when the median pH over 30 days is greater than or equal to 6.5 2. the value determined by the following relationship at median pH less than 6.5 Dissolved Aluminum = e (1.6-3.327 (median pH) + 0.402 (median pH)²) Note 1.12 for Arsenic (dissolved): The recommended guideline is for total arsenic. Note 1.13 for Boron (dissolved): The recommended guideline is for total boron. Note 1.14 for Cadmium (dissolved): The guideline for cadmium is determined on a site-specific basis according to the local water hardness. The guideline for cadmium (dissolved) in μg/L is determined by the following equations for short term exposure: 1. If hardness (as CaCO3) is less than 7 mg/L then maximum is 0.0380 μg/L 2. If hardness (as CaCO3) is from 7 to 45 mg/L then maximum is based on equation: e to the power of {1.03[ln(hardness)] - 5.274} 3. If hardness (as CaCO3) is greater than 455 mg/L then maximum is 2.8 μg/L. When water hardness is greater than the upper bound (i.e., highest water hardness tested), a site-specific assessment may be required. Note 1.15 for Cobalt (dissolved): The interim maximum concentration for total cobalt is 110 µg/L to protect aquatic life in the freshwater environment from acute effects of cobalt. The interim 30-day average concentration for total cobalt (based on five weekly samples) is 4 µg/L to protect aquatic life from chronic effects of cobalt. Note 1.16 for Cobalt (total): The interim maximum concentration for total cobalt is 110 µg/L to protect aquatic life in the freshwater environment from acute effects of cobalt. The interim 30-day average concentration for total cobalt (based on five weekly samples) is 4 µg/L to protect aquatic life from chronic effects of cobalt. Note 1.17 for Copper (dissolved): The maximum concentration of total copper should not exceed at any time the numerical value (in µg/L) given by the formula "0.094(hardness)+2", where water hardness is reported as mg/L CaCO3. The 30-day average concentration of total copper (based on a minimum of 5 approximately weekly samples) should not exceed 2 µg/L when average water hardness over the same period (expressed as mg/L CaCO3) is less than 50 mg/L. When average water hardness is greater than 50 mg/L the 30-day average concentration should not exceed the numerical value (in µg/L) given by the formula "0.04(average hardness)", where water hardness is reported as mg/L CaCO3. Note 1.18 for Copper (total): The maximum concentration of total copper should not exceed at any time the numerical value (in µg/L) given by the formula "0.094(hardness)+2", where water hardness is reported as mg/L CaCO3. The 30-day average concentration of total copper (based on a minimum of 5 approximately weekly samples) should not exceed 2 µg/L when average water hardness over the same period (expressed as mg/L CaCO3) is less than 50 mg/L. When average water hardness is greater than 50 mg/L the 30-day average concentration should not exceed the numerical value (in µg/L) given by the formula "0.04(average hardness)", where water hardness is reported as mg/L CaCO3. Note 1.19 for Lead (dissolved): The maximum guideline for total lead in water, at a water hardness less than or equal to 8 mg/L as CaCO3 is set at 3.0 µg/L. When water hardness exceeds 8.0 mg/L CaCO3 the maximum guideline for lead at any time is given by the following equation: Maximum Criteria (µg/L) = exp (1.273 ln(hardness) - 1.460). The 30-day average guideline for total lead in water, when water hardness exceeds 8 mg/L as CaCO3, is as follows: 30-Day Average (µg/L) is less than or equal to 3.31 + exp (1.273 ln (mean hardness) - 4.704). For hardness less than or equal to 8.0 mg/L there is no 30-day average guideline; hence the maximum concentration of 3.0 µg/L is used.

Note 1.20 for Lead (total): The maximum guideline for total lead in water, at a water hardness less than or equal to 8 mg/L as CaCO3 is set at 3.0 µg/L. When water hardness exceeds 8.0 mg/L CaCO3 the maximum guideline for lead at any time is given by the following equation: Maximum Criteria (µg/L) = exp (1.273 ln(hardness) - 1.460). The 30-day average guideline for total lead in water, when water hardness exceeds 8 mg/L as CaCO3, is as follows: 30-Day Average (µg/L) is less than or equal to 3.31 + exp (1.273 ln (mean hardness) - 4.704).

3. Notes for Guidelines for Canadian Drinking Water Quality - Maximum Acceptable Concentrations (GCDWQ MAC) Note 3.1 for Turbidity: Waterworks systems that use a surface water source or a groundwater source under the direct influence of surface water should filter the source water to meet health-based turbidity limits, as defined for specific treatment technologies. Where possible, filtration systems should be designed and operated to reduce turbidity levels as low as possible, with a treated water turbidity target of less than 0.1 NTU at all times. Where this is not achievable, the treated water turbidity levels from individual filters should meet the requirements described in GCDWQ. For systems that use groundwater that is not under the direct influence of surface water, which are considered less vulnerable to faecal contamination, turbidity should generally be below 1.0 NTU. For effective operation of the distribution system, it is good practice to ensure that water entering the distribution system has turbidity levels below 1.0 NTU.

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 methods 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 methods 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.

REPORTED TO Western Water Associates Ltd WORK ORDER 5050588 PROJECT CSRD Refuse Disposal - Sicamous PE00514 REPORTED May-15-15
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 methods 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 methods 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.

REPORTED TO Western Water Associates Ltd WORK ORDER 5080986 PROJECT CSRD Refuse Disposal - Sicamous PE00514 REPORTED Aug-24-15
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 methods 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 methods 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.
