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. | #106 – 5145 26 St., Vernon, BC, Canada, V1T 8G4 | P:1.250.541.1030 | www.westernwater.ca | 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.
