site operating permits do not allow the landfill to accept hazardous <br /> wastes. <br /> The original ground-water monitoring program, as approved by the <br /> CVRWQCB, was implemented in 1980. That program involved quarterly <br /> sampling of six privately owned water supply wells (the Sawyer, <br /> Goehring, Whittaker, Hall , labor camp, and the landfill water supply <br /> wells) . As specified in the terms of Waste Discharge Requirement <br /> Order No. 78-147, the ground-water samples collected from these wells <br /> were analyzed for specific conductance, pH, nitrate hardness, chemical <br /> oxygen demand, chloride, and nitrate-nitrogen. The analytical results <br /> indicate that the drinking water standards for these parameters, as <br /> specified in California Administrative Code, Title 22, Sections 64435 <br /> and 64473, have not been exceeded. <br /> Five of the six above-mentioned wells (the Sawyer, Goehring, <br /> Whittaker, Hall , and landfill water supply wells) were included in the <br /> sampling and analysis program discussed in this report. Because the <br /> sixth well (the labor camp well) has been deleted from the most recent <br /> sampling events conducted by the San Joaquin County Flood Control and <br /> Water Conservation District, that well was not included in EMCON's <br /> current work plan. <br /> FIELD INVESTIGATIVE PROCEDURES <br /> Four monitoring wells (MW-1, MW-2, MW-3, and MW-4) were installed by <br /> EMCON between March 18 and March 31, 1987, at the existing Harney Lane <br /> Sanitary Landfill . The locations of these wells are shown on Fig- <br /> ure 3. <br /> i <br /> Drilling, Pro ram <br /> Planned locations for the wells were intended to correspond with those - <br /> proposed in the ground-water monitoring program prepared by J.H. <br /> Kleinfelder and Associates in 1986 (see Appendix A) .
