INTRODUCTION <br /> General <br /> This First Semester 2008 Monitoring Report for the Foothill Sanitary Landfill (FSL) is submitted in <br /> compliance with Waste Discharge Requirements (WDR) Order No. R5-2003-0020. <br /> The FSL is located in eastern San Joaquin County at 6484 N. Waverly Road, four miles east of Linden, CA <br /> (Figure 1). Land uses within 1,000 feet of the facility are agricultural. The vicinity receives an average of <br /> ' about 18 inches of precipitation per year. <br /> The FSL is a single Class III Waste Management Unit on an 800-acre parcel. This Unit is comprised of <br /> Module "I", Module 1, and future modules. Future modules will overlap onto the completed modules until <br /> final closure of the Unit. The size of future modules will be selected in accordance with the refuse disposal <br /> rate. <br /> Waste discharged to the landfill includes commercial and household waste, construction/demolition waste, <br /> and agricultural waste. Disposal in this semester occurred over Module 1 (Figure 2). <br /> The total capacity of the landfill is approximately 102 million cubic yards. The active life of the facility is <br /> estimated to allow disposal until the year 2058, based on current disposal rates and capacities. The estimated <br /> service life will change if disposal rates differ significantly than those predicted. The quantity of waste <br /> placed during the reporting period is shown in Table 1. <br /> TABLE 1 <br /> First Semester 2008 Monthly Refuse Disposal <br /> Foothill Sanitary Landfill <br /> 1 Refuse Disposal <br /> Month (Tons) <br /> JAN 19,992.2 <br /> FEB 18,681.1 <br /> MAR _ 21,759.7 <br /> APR 22,268.4 <br /> MAY 20,827.5 <br /> JUNE 20,128.0 <br /> r <br /> Geology <br /> The first water bearing zone encountered is in sandy gravel at a depth of more than 200 feet. Groundwater <br /> elevations range from approximately 46 to 61 feet MSL. The groundwater is unconfined or partially <br /> confined. Groundwater elevations fluctuate less than one foot seasonally. <br /> Above the water bearing zone, the soil layers are moderately to well-cemented layers of sandstone and <br /> siltstone with claystone and conglomerates. This soil is mostly moderately slow in permeability with <br /> sporadic sandy layers that are well drained. <br /> Foothill Sanitary Landfill 3 Department of Public Works/Solid Waste <br /> 1"Semester 2008 Groundwater Monitoring County of San Joaquin—July 31,2008 <br />
