Remediation System Installation Report <br /> Former STOCKTON PLATING Facility <br /> 632 South El Dorado Street, Stockton, California <br /> 1.0. INTRODUCTION <br /> At the request of Mr Richard Leland of R and L Business Management of Stockton, Advanced <br /> GeoEnviromnental, Inc (AGE) has prepared this report for 632 South El Dorado Street, Stockton, <br /> California (the site) <br /> This report documents the preparation of a ground water remediation system, which was installed <br /> between September 2003 and March 2004, performance of remediation start-up and operation, <br /> including influent and effluent ground water samples from the remediation system, and installation <br /> of a soil vapor extraction (SVE)remediation system The site setting is illustrated on Figure 1 The <br /> locations of structures and monitoring wells on the site are depicted in Figure 2 <br /> Background information, including details of previous site assessment work are presented in <br /> Appendix A Results from previous ground water monitoring events are included In the tables of this <br /> report <br /> 2.0. PROCEDURES <br /> Field work was conducted in accordance with the Final Remediation Plan, dated 23 April 2002 and <br /> Final Remediation Plan Addendum, dated 18 July 2003,was approved by the EHD on 29 July 2003 <br /> A remediation enclosure and fencing for the ground water treatment system was installed on 03 <br /> November 2003 Ground water remediation equipment was delivered at the site on 12 November <br /> 2003 Soil remediation equipment was delivered at the site on 17 November 2003 Between 29 <br /> September and 01 November 2003 an associated piping network was installed at the site The <br /> dedicated electrical service was installed on 18 November 2003 The interconnection for the ground <br /> water recovery and treatment system were installed and inspected between 01 January and 09 <br /> February 2004 <br /> 21 SOIL-VAPOR EXTRACTION SYSTEM INSTALLATION <br /> The SVE system utilized two-inch diameter, schedule 40 PVC piping installed underground from <br /> each well-head at vapor extraction wells and ground water extraction wells EW-1 and EW-2 to the <br /> inlet of the vacuum blower, the outlet from the vacuum blower was routed through the catalytic <br /> oxidizing unit A Magnehelic vacuum gauge was attached to the inlet of the blower The air flow was <br /> monitored using a Dwyer DS-200 flow sensor The flow rate was determined from the measured <br /> . differential pressure and the piping diameter using a nomograph (Appendix B) The vapor stream <br /> at the SVE inlet was monitored for the presence of organic vapor using an OVA <br /> Advanced GeoEnvironmental,Inc <br />
