' Bank of Stockton - Cutter Lumber Site Page 11 <br /> Groundwater Monitoring Well Construction <br />' Project No 102 2 <br /> April 24, 1998 <br /> Itoluene, ethylbenzene, and xylene (BTEX) using EPA method 8020 Total <br /> Petroleum Hydrocarbons measured as gasoline were analyzed using EPA <br />' method 5030/8015m, and Total Extractable Petroleum Hydrocarbons measured <br /> as diesel by EPA method 3540/8015m One sample was also tested for total lead <br /> content by EPA method 3050/6010 <br />' Groundwater <br /> Groundwater samples were collected from each of the seven wells and from the <br />' two existing older wells as descried above All samples were submitted to <br /> Sherwood Laboratories following Chain of Custody protocol and were tested for <br /> the presence of benzene, toluene, ethylbenzene, and xylene (BTEX) using EPA <br />' method 602, and Total Petroleum Hydrocarbon as gasoline (TPH-G) by EPA <br /> method 5030/8015m Total Extractable Petroleum Hydrocarbons measured as <br /> diesel (TEPH-D) was analyzed using EPA method 3510/8015m As directed by <br />' the San Joaquin County PHS/EHD, three samples were also tested for the <br /> presence of five oxygenated compounds commonly used as gasoline additives (T- <br /> Butanol, MTBE, DPE, ETBE & TAME) using EPA method 8260 <br /> Laboratory testing was also performed to document certain geo-technical <br />'. characteristics of the soil This testing was performed in anticipation of possible <br /> future "fate and transport" modeling which may be needed if a Risk Based <br /> Corrective Action (RBCA) approach is used as a part of this project The geo- <br /> technical data would be used as input data to the modeling program <br /> 3.3 Soil & Groundwater Analytical Results <br />' The results of analytic testing for gasoline and diesel range hydrocarbons and <br /> BTEX compounds are summarized in Summary Tables 1 and 2 The lab data <br />' sheets are attached as Appendix A The single soil sample tested for total lead <br /> (MW7-45) did not contain detectable lead The water samples which were tested <br /> for oxygenated compounds MW-4, MW-7, and MW-8A contained no detectable <br />' levels of these compounds <br /> 1 <br /> 1 <br /> 1 <br />' 2937 Veneman Ave ,#B240 Geo-Phase Environmental Inc Phone (209) 569-0293 <br /> Modesto, CA 95356 Fax (209) 569-0293 <br /> 1 <br />
