c <br /> 1.0 BACKGROUND <br /> 1.1 PURPOSE <br /> This work plan presents the procedures for the installation of groundwater <br /> (GW) monitoring well at Harney Lane Landfill (HLSL) and North County <br /> Recycling Center And Sanitary Landfill (NCRCSL). <br /> 1.2 SITE DESCRIPTION <br /> A. HARNEY LANE LANDFILL <br /> HLSL is a single, closed, unlined Class III landfill located at 14750 <br /> E. Harney Lane in Lodi, California. The landfill covers approximately 127 <br /> acres, which consists of one 97-acre primary site and a 15-acre secondary <br /> site. The remaining property area is comprised of access roads, storm <br /> water retention ponds, setbacks for environmental monitoring, and <br /> firebreaks. HLSL was closed in 1996 and now is under postclosure <br /> maintenance. <br /> 1. Geology and Hydrogeology <br /> GW is first encountered approximately 120 feet below the surface at HLSL, <br /> and fluctuates approximately 4 feet during a year. The average GW <br /> elevation is decreasing steadily over time. <br /> B. NORTH COUNTY RECYCLING CENTER AND SANITARY LANDFILL <br /> NCRCSL is located at 17720 East Harney Lane, approximately nine miles <br /> east of Lodi. It is a single solid waste management unit, designated Class <br /> III, accepting non-hazardous municipal solid waste and inert waste. The <br /> site is 185 acres in area, comprised of lined modules, each constructed on <br /> an as-needed basis. The landfill is expected to close in 2032, based on <br /> current disposal rates and current permitted capacity. <br /> 1. Geology and Hydrogeology <br /> The GW monitoring well network at NCRSL consists of up-gradient well G-1 <br /> and down-gradient wells G-3D, G-4, G-5, and G-6. Depth of GW is 145 to <br /> 157 feet below ground surface at NCRCSL and fluctuates approximately 6 <br /> feet a year. <br /> Work Plan-Groundwater Monitoring Well Installation San Joaquin County <br /> November 23,2009 Department Of Public Works <br /> 1 Solid Waste Division <br />
