Ms. Roberta M. Kaitz <br /> Kaitz Property Services <br /> June 11, 1996 <br /> Page 2 <br /> Upon approval of the SJCPHS,Hygienetics will collect five subsurface soil samples from the area in <br /> front of and within the County Hollow Apartments (fronting on Morgan Place). Samples will be <br /> collected using a direct push sampler on a track-mounted drilling rig. Relatively undisturbed soil ? <br /> samples will be collected in brass or plastic tubes at approximately 2.0 to 3.0 feet (ft) and 5.0 ft to C17� <br /> 6.0 ft below surface grade (bsg)unless obvious or noticeable hydrocarbon contamination occurs or <br /> groundwater or sample refusal is encountered. Borings will be advanced to approximately 10 ft bsg <br /> to determine soil characteristics. Soils will be logged (classified) in the field using the Uniform Soil <br /> Classification System(USCS). <br /> Soil samples, from the 2.0 ft to 3.0 ft depth interval will be submitted to a California Department of <br /> Health Services(DHS)accredited laboratory and analyzed for TPH extractable (diesel, kerosene, and <br /> motor oil) using EPA Method 8015 (modified), volatile organic compounds (VOCs) using EPA <br /> Method 8240a, and for California Code of Regulations(CCR) Title 22 (CAM 17) metals using EPA <br /> 6000 and 7000 series. Soil samples from the deeper interval(5.0 ft to 6.0 ft bsg)will be held pending <br /> receipt of the analysis from the shallow(2.0 ft to 3.0 ft) interval). <br /> Although the direct push method will not generate large quantities of soil cuttings, excess soil from <br /> the sampling, logging, and.equipment rinsate water from the cleaning of the drilling equipment will <br /> be contained in 55-gallon drums or similar containers. These will be disposed of in accordance with <br /> the appropriate regulatory agency requirements; however, containers will be required to remain on <br /> site until analyses are obtained. Soil and rinsate water will be analyzed for TPH extractable (diesel, <br /> kerosene and motor oil)using EPA Method 8015 (modified), VOCs using EPA Method 8240a/624, <br /> and CCR Title 22 metals using EPA 6000 and 7000 series methods. <br /> All direct push soil borings will be grouted to the surface using neat Portland cement. <br /> Report <br /> Hygienetics will prepare a written report that will include boring logs, chain of custody forms, and <br /> copies of the laboratory analytical data sheets. A copy of the report must be submitted to the <br /> SJCPHS as agreed in the permit application for soil borings. <br /> 4234.001\cntry I.wrk <br /> Hygienetics® <br /> Environmental <br />
