' KLEINFELDER <br /> The soil borings will be advanced using a truck-mounted drill rig equipped with 8-inch <br /> hollow stem augers The borings will be drilled, logged, and sampled following the <br /> protocol described in Attachment A <br /> Task A03 - Reporting <br /> I 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 />' 0 A description of the field activities, observations, and protocols <br /> • Lithologic Logs <br /> • Tabulated results of soil and groundwater (optional) samples with copies of certified <br /> results <br /> • A groundwater elevation contour map for the monitoring event and an estimate of the <br /> 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 Turkette of the SJCEHD, if hydrocarbons are present in the soil of any of <br /> the proposed borings at a depth of 35 feet or more, the installation of groundwater <br /> monitoring wells on site will be required Therefore, the eight bormgs will be backfilled <br /> with a neat cement to grade, and three groundwater momtonng wells will be constructed <br /> on-site outside of the areas of known soil contamination <br /> The three (3) borings will be drilled approximately 10 to 15 feet into groundwater (to a <br /> depth of approximately 80 feet bsg) Following completion of the drilling, a 2-mch <br /> diameter PVC well will be installed in each boring The well will be constructed as <br /> described in Attachment A The wells will be surveyed for well location and elevation <br /> above mean sea level (msl) so that subsequent water level sounding data can be utilized in <br /> determining groundwater flow directions and gradient as described in Attachment A <br /> Forty-eight hours after installation, the new wells will be developed to remove sediment- <br /> laden water and to increase the hydraulic radius of each well Development will be <br /> performed as described in Attachment A <br /> DH and 7EI94 Page 3 of 6 <br /> Copyright 1994 Kleinfelder Inc <br />
