KLEINFELDER <br /> 3_0 SMPE OF WORK <br /> This section describes the installation of two temporary ground water <br /> monitoring wells to assess the presence of volatile organics, volatile <br /> halocarbons, and the metals zinc and chrmium. These constituents were <br /> identified in ground water at Kearney KPF, north of the site (see Plate <br /> 1) . <br /> Following laboratory analysis, the well casings will be pulled and the <br /> borings will be grouted to the surface with a cement bentonite grout. <br /> 3.1 Soil Borings <br /> The soil borings will be drilled with a truck-mounted drill rig equipped <br /> with 6 or 8-inch diameter hollow-stem augers and capable of angle <br /> drilling. During the drilling, an experienced environmental geologist <br /> will classify the subsurface sediments, and log the boreholes. <br /> To minimize the potential for cross-contamination, all augers and <br /> associated equipment will be steam-cleaned prior to the drilling of each <br /> borehole. The sampling equipment will also be cleaned with a <br /> phosphate-free detergent scrub and a distilled water rinse prior to the <br /> collection of each soil sample. <br /> 3.1.1 Soil Sampling Procedures <br /> Soil samples will be collected to axuplete lithologic logs, and for <br /> possible chemical analysis. Samples will be collected at 5-foot intervals <br /> starting at a depth of 5-feet below the ground surface. Sample collection <br /> will proms to a depth where ground water is encountered. <br /> 45-88-01 6 <br />
