i <br /> Site Background information <br /> FORMER FISCO WAREHOUSE (Howard Lenz Property) <br /> I1648 Shaw Road, Stockton, California <br /> The greatest vacuum was measured in the observation point nearest the extraction well <br /> (VW-1) The lowest vacuum was measured in MW-6, approximately 66 feet north of the <br /> extraction point The maximum vacuum measured at the observation points during the pilot <br /> test was plotted versus the distance from the extraction well The effective radius of influence <br /> was determined by drawing a best-fit line though these data points to correlate distance to <br /> vacuum data At a vacuum potential of 0 10 inches of water, the radius of influence is <br /> approximately 47 feet, at an induced vacuum potential of 10 inches of water, the radius of <br /> influence Is approximately 30 feet, at 10 0 inches of water the radius of influence Is <br /> approximately 13 feet Based on the United States Environmental Protection Agency(EPA)- <br /> prepared document,How to Evaluate Alternative Cleanup Technologies For UST sates the <br /> radius of influence is considered to be the distance from the extraction well at which a <br /> vacuum of at least 0 1 inches of water Is observed Based upon an effective vacuum potential <br /> of 0 1 inches of water, the calculated effective radius of influence at the site will be <br /> approximately 47 feet <br /> On 31 July 2003, ground water monitoring well MW-8 was installed at the site to a depth of 95 feet <br /> bsg Seven soil samples were submitted for laboratory analysis from pilot boring MW8 THP-g, <br /> TPH-d,BTEX and fuel additives were not detected at or above laboratory reporting limits in the soil <br /> samples submitted TPH-g,TPH-d,BTEX and fuel additives were not detected at or above reporting <br /> limits In the first ground water sample collected in August 2003 from MW-8 <br /> Advanced Geo Environmental,Inc <br />
