I <br /> CAMBRIA <br /> Soit samples will be retained in stainless steel or brass sample- tubes and will be covered on <br /> both ends with Teflon sheets and plastic end caps. Soil samples will be labeled, entered onto a <br /> chain-of-custody record and placed into a cooler with ice for transport to a State of <br /> California certified laboratory for analyses. <br /> approximately ten feet below first encountered groundwater. <br /> � Each boring will be drilled to appro y <br /> The wells will be competed using four-inch diameter Schedule 40 PVC casing. The well screen <br /> interval will be approximately five feet above and ten feet below first encountered <br /> groundwater. The sandpack will be placed from the bottom of the well screen up to two feet <br /> above the top of the well screen followed by a two-foot thick bentonite seal and cement <br /> grout to grade. Actual well construction details will be based on field conditions during <br /> drilling. The well will be secured with a locking cap under a traffic-rated well box. A licensed <br /> surveyor will survey the wellhead elevations (including existing well MW-5) relative to mean <br /> sea level and the location of each well. <br /> Well Development and Sampling: Blaine Tech Services, Inc. (Blaine) of San Jose, California <br /> will develop the new wells, gauge groundwater depths, collect groundwater samples, and submit <br /> the samples to a State of California certified laboratory for analyses for all site wells. <br /> 1 Chemical Analyses: Groundwater samples and selected soil samples will be analyzed for <br /> TPHg by EPA Method 8015 (modified) and BTEX and MTBE by EPA Method 8020. <br /> Groundwater samples from all wells will be analyzed for MTBE by EPA Method 8260, and <br /> groundwater samples from wells MW-6 through MW-8 wells will also be analyzed for tertiary 1 <br /> { amyl methyl ether, ethyl tertiary butyl ether, tertiary 'butyl.alcohol, and di-isopropyl ether <br /> by EPA Method 8260. <br /> Report Preparation: Following the receipt of analytical results from the laboratory, Cambria <br /> j will,prepare a written report which will include field procedures, laboratory results, boring <br /> I logs, and conclusions. <br /> SCHEDULE <br /> 1 <br /> Cambria is prepared to begin work upon approval of this work plan by SJCPHS/EHD and <br /> f <br /> { receipt of the appropriate drilling and encroachment -permits.
