Remediation Report - Fourth Quarter 2005 <br /> WATERLOO FOOD & FUEL <br /> 3032 East Waterloo Road, Stockton, California <br /> 1.0. INTRODUCTION AND SCOPE OF WORK <br /> At the request of Mr Paul Sidhu,Advanced GeoEnvironmental,Inc (AGE)has prepared this report <br /> for the site located at 3032 East Waterloo Road, Stockton, California(site) The report documents <br /> procedures and results of remediation of the ground water during the fourth quarter 2005 The <br /> location of the site is illustrated on Figure 1, locations of structures, soil borings and monitoring <br /> wells at the site are depicted on Figure 2 Interim ground water remediation by ground water <br /> extraction was initiated at the site on 20 May 2003, in accordance with procedures outlined in the <br /> AGE-prepared Interim Remediation and Site Assessment Work Plan, dated 25 January 2001 Site <br /> background information is provided in Appendix A <br /> 2.0. GROUND WATER EXTRACTION -TREATMENT REMEDIATION <br /> Ground water remediation system installation and operation was performed in accordance with <br /> procedures described in the approved Interim Remediation and Site Assessment Work Plan, dated <br /> 25 January 2001 and Interim Remediation Work Plan -Addendum, dated 16 September 2002 The <br /> • ground water extraction system consisting of the ground water treatment unit and associated piping <br /> was installed between 18 February and 26 June 2003 (Figure 3) <br /> 21 GROUND WATER REMEDIATION SYSTEM <br /> The ground water treatment system is designed to operate at a maximum flow rate of 5 gallons per <br /> minute(GPM), therefore, each of the four recovery wells was adjusted to extract ground water at a <br /> flow rate of approximately 2 GPM by extracting on an intermittent cycle The operation of the <br /> ground water pumps allows for a hiatus when water falls below the pump inlet to allow the well to <br /> recharge, after which the pump reactivates <br /> The ground water treatment system operates on a batch basis,approximately 200 gallons of extracted <br /> ground water is treated and discharged,with a daily total of up to 4,000 gallons Total flow(totalizer) <br /> was recorded utilizing the Blue-White Industries F-2000 inline flow meter The treated water <br /> (effluent)is discharged to the City of Stockton municipal waste water treatment facility Calibration <br /> documents are provided in Appendix B <br /> 22 MONTHLY MONITORING PROCEDURES <br /> In order to quantify the mass of contamination removed from each extraction well and to comply <br /> with the requirements of the City of Stockton discharge permit, monthly monitoring and sampling <br /> Advanced GeoEnvironmentai,Inc <br />
