0 <br /> CAM B R I A <br /> analyses, and organic vapor screening using a photo-ionization detector (PID). Cambria will <br /> prepare an exploratory boring log for the well and PID measurements will be recorded on the log. <br /> Soil samples designated for possible chemical analyses will be retained in stainless steel or brass <br /> sample tubes. The tubes will be covered on both ends with Teflon sheets and plastic end caps. <br /> Soil samples will be labeled,entered onto a chain-of-custody record and placed into a cooler with <br /> ice for transport to a State of California certified laboratory for analyses. A standard two-week <br /> tum-around time will be requested for laboratory results. <br /> © Monitoring Well Installation: The well will be constructed using 2-inch diameter Schedule 40 <br /> PVC casing. The well screen interval will be approximately 5 feet above and 10 feet below fust <br /> encountered groundwater. The sandpack will be placed from the bottom of the well up to two <br /> feet above the top of the well screen followed by a 2-foot thick bentonite seal and cement grout <br /> to grade. Actual well construction details will be based on field conditions during drilling. The <br /> well will be secured with a locking cap under a traffic-rated well box. <br /> Well Development and Sampling: Blaine Tech Services, Inc. (Blaine) of San Jose, California <br /> will develop the new well prior to sampling. After well development, the well will be sampled <br /> along with all of the site wells during the next regularly scheduled quarterly sampling event. <br /> Chemical Analyses: Groundwater samples collected from well MW-13 will be analyzed for the <br /> same constituents that the core wells are being analyzed for (Table 1). We do not intend to <br /> analyze soil samples collected from the well boring as adequate soil assessment has already been <br /> performed at this site. However, if while drilling well MW-13, we find indications of impacted <br /> soil,we may choose to perform some soil sample analysis. <br /> Wellhead Survey Activities: Following monitoring well installation, a licensed surveyor will <br /> survey wellhead elevations relative to mean sea level and the latitude and longitude of the wells. <br /> Report Preparation:Following the receipt of analytical results from the laboratory, Cambria will <br /> prepare a written report, which will include field procedures,laboratory results, a boring log, and <br /> conclusions. <br /> The scope of work described in this work plan will be performed under the supervision of a <br /> registered geologist. <br /> 1015 4 <br />
