QUARTERLY REPORT <br /> June 1996 <br /> IGeweke Land Development & Marketing <br /> 16 South Cherokee Lane <br />' Lodi, California <br />' 1.0. INTRODUCTION AND SCOPE OF WORK <br /> At the request of Geweke Land Development & Marketing (GLDM), and in accordance with <br />' Cleanup and Abatement Order No. 93-701,Advanced GeoEnvirorunental, Inc. (AGE) has prepared <br /> this report of monitoring and remediation field activities performed at 16 South Cherokee Lane, <br /> Lodi, California during the second quarter of 1996. A vicinity map of the site is illustrated on Figure <br /> I - Vicinity Map. A plan of the site is illustrated on Figure 2 - Site Plan. <br /> In accordance with the Revised Monitoring and Reporting Prograrn No. 94-701, ground water and <br /> soil vapors are scheduled for monitoring on a periodic basis for microbiological activities. The scope <br /> of work is to evaluate the field data and summarize the progress of in-situ bioremediation and <br /> monitoring activities at the site during the second quarter of 1996. Results of previous investigation <br /> and monitoring at the site are detailed in the Problem Assessment Report (PAR) and prior Quarterly <br /> Reports. <br /> 2.0. PROCEDURES <br /> 2.1. MONITORING OF MICROBIOLOGICAL ACTIVITIES IN GROUND WATER <br /> Ground water samples were collected from MW-6, MW-7, MW-10, MW-11, MW-13, MW-14 and <br /> EW-1 on 25 April and 23 May 1996; ground water samples were collected from MW-6 through <br /> MW-14 and EW-1 on 19 June 1996. Sampling was performed in accordance with Revised <br /> Monitoring and Reporting Program No. 94-701 prepared by the CVRWQCB. <br /> All samples were collected using disposable plastic bailers or pre-cleaned PVC bailers and were <br /> monitored in the field for dissolved oxygen, pH and electrical conductivity (EC). Following the <br /> procedures described in Section 2.3., samples for microbiological evaluation were collected in 40-m1 <br /> VOA vials with no added preservative, and Nvere transported to A. Keith Kaufman, M.S. in Culver <br /> City, California. The samples were analyzed for physicochemical properties and microbiological <br /> enumeration. Table 1 and Table 2 summarize the results of these activities through .lune 1996. <br /> 2.2. SOIL VAPOR MONITORING <br /> Seven remediation wells (VW-1 through VW-7), three monitoring wells (MW-3 through MW-5) <br /> which are presently dry, and MW-14 are connected to a low-pressure blower that provides oxygen <br />
