Store <br /> ~ #37, located at 15 Grant Line Road in Tracy, San Joaquin County, California(the site)`-is <br /> submitted by H2OGEOL on behalf of The Customer Company. The site location is shown <br /> on Figure 1. The property is now a Bonfair Market, having been operated by <br /> Convenience Acquisition Corporation as a More for Less store in the interim. <br /> The depth to first encountered groundwater at the site was reported as being between six <br /> and 7.5 feet beneath the surface in the aforementioned reports and static water levels mi <br /> monitoring wells has ranged from about five to ten feet over the last 15 years. Since the <br /> soils in these depth ranges have been reported as fine grained, soil samples for <br /> implementation of the present work plan will be collected by hand operated.tools as <br /> described- w. <br /> I <br /> I <br /> P.0.Box 2165 ■ Livermore,California 94551-2165 0 (925)373-9211 <br />
