SOIL INVESTIGATION WORKPLAN <br /> 200 North Beckman Road <br /> Lodi, San Joaquin County, California <br /> 1.0 INTRODUCTION <br /> This Workplan has been prepared by ALFA for submission to the San Joaquin <br /> County Environmental Health Department ("EHD")• Three exploratory soil <br /> borings will be drilled, samples collected and analyzed to determine if any <br /> hydraulic oil exist in the hydraulic lift area. <br /> Prior to conducting field activities, a Health and Safety Plan (HASP) will be <br /> Prepared for the proposed field sampling activities. Prior to conducting field <br /> activities , ALFA will conduct a site visit to mark the direct-push sampling locations <br /> as required by Underground Service Alert for underground utility identification. <br /> Prior to conducting field activities, a drilling permit will be obtained from the EHD. <br /> The vertical extent of affected soils (if any) will be defined by analyzing <br /> soil samples collected during the drilling of three (3) soil borings. <br /> The proposed soil boring location is presented on Figure 1, attached. <br /> The borings will be advanced using Geoprobeo/Hydro-punch direct <br /> push equipment. All samples will be logged by a California-Registered <br /> Professional Geologist (PG #7503) using the Unified Soil Classification <br /> System (USCS) per American Society for Testing and Material (ASTM) method <br /> D-2488. A 2-3/8-inch diameter dual-tube sampling rod will be hydraulically <br /> advanced to collect continuous in-situ soil samples. The sample rod, with a <br /> clear polyvinyl chloride (PVC) liner inside it, will be advanced at four-foot <br /> intervals. To collect the sampling rod will then be withdrawn along with the <br /> soil-containing PVC liner. A new PVC tube liner will be attached to the sample <br /> retrieval rods and the process repeated at 4-foot intervals to reach the targeted <br /> sample depth. <br />
