KLEINFELDER <br /> File No. 20-YP4071 <br /> June 23, 1994 <br /> The samples will be analyzed on a normal laboratory schedule requiring approximately two <br /> weeks (ten working days) for completion. <br /> The soil borings will be advanced using a truck-mounted drill rig equipped with 8-inch hollow <br /> stem augers. The borings will be drilled, logged, and sampled following the protocol <br /> described in Attachment A. <br /> Task A03 - Reporting <br /> Upon completion of the field activities and receipt of the analytical results, a report of <br /> findings will be prepared for client and agency review. The report will include: <br /> A description of the field activities, observations, and protocols <br /> Lithologic logs <br /> Tabulated results of soil and groundwater (optional) samples with. copies of <br /> certified results <br /> A groundwater elevation contour map for the monitoring event and an estimate <br /> of the groundwater gradient direction(optional) <br /> Description and documentation of QA/QC procedures employed for field and <br /> laboratory work <br /> Kleinfelder's conclusions and recommendations based on the data acquired <br /> Optional Task A04: - Monitoring Well Installation, Development, and Sampling <br /> According to Ms. Turkatte of the SJCEHD, if hydrocarbons are present in the soils of either <br /> boring at a depth of 35 feet, the installation of groundwater monitoring wells on site will be <br /> required. Therefore, the two borings will be backfilled with a neat cement to grade, and three <br /> groundwater monitoring wells will be constructed on-site outside of the areas of known soil <br /> contamination. <br /> The boring will be drilled approximately 10 to 15 feet into groundwater (approximately 80 <br /> feet bsg). Following completion of the drilling, a 2-inch diameter PVC well will be installed <br /> in each boring. The well will be constructed as described in Attachment A. The wells will <br /> be surveyed for well location and elevation above mean sea level (msl) so that subsequent <br /> water level sounding data can be utilized in determining groundwater flow directions and <br /> gradient as described in Attachment A. <br /> ETH:md 3E/94 Page 3 of 6 <br /> Copyright 1994 Kleinfelder, Inc. <br />
