The location of the GW monitoring wells at all sites are away from the <br />refuse footprint (Figure 1-3). Well installation work will not include drilling <br />into refuse or contact with refuse. Well locations will be adjusted in the <br />field based on site conditions. The wells will be surveyed after installation. <br />1.6 CONSTRUCTION SCHEDULE <br />SWD will schedule installation of the GW monitoring wells after approval of <br />drilling permits from San Joaquin County Environmental Health Department <br />(EHD). Drilling and installation of each GW well will take minimum of 4 <br />working days. The work hours will be Monday to Friday from 7:00 am to <br />4.30 pm. <br />Work Plan- Groundwater Monitoring Well Installation San Joaquin County <br />May7, 2013 Department Of Public Works <br />2 Solid Waste Division <br />C. Foothill Sanitary Landfill <br />FHSL is located in eastern San Joaquin County at 6484 N. Waverly <br />Road, four miles east of Linden, CA. The landfill is a single Class III <br />Waste Management Unit on an 800 -acre parcel. This Unit is comprised <br />of Module "I", Module 1, and future modules. Future modules will <br />overlap onto other completed modules, including Module "I" until final <br />closure of the Unit. Waste discharged to the landfill includes <br />commercial and household waste, construction/ demolition waste, and <br />agricultural waste. <br />1. Geology and Hydrogeology <br />The first water bearing zone encountered is in sandy gravel at a depth <br />of more than 200 feet below the ground surface. Groundwater <br />elevations vary between approximately 38 and 61 feet MSL. <br />Groundwater elevations fluctuate less than one foot seasonally. The <br />groundwater is unconfined or partially confined. Above the water - <br />bearing zone, the soil layers are moderately to well -cemented layers of <br />sandstone and siltstone with claystone and conglomerates. This soil is <br />mostly moderately slow in permeability with sporadic sandy layers that <br />are well drained. <br />1.3 REASON FOR INSTALLING GW MONITORING WELLS <br />The new GW wells will replace existing d GW wells at each site. The <br />p g ry <br />existing dry wells have become dry due to drop in groundwater elevation <br />over time. The dry existing dry wells will be kept as background <br />monitoring wells. <br />1.4 WELL LOCATION <br />The location of the GW monitoring wells at all sites are away from the <br />refuse footprint (Figure 1-3).
