silty clayey sand A zone aquifer from the B zone aquifer that is found at approximately <br /> 21 feet bgs and is approximately 6 to 7 feet thick The B zone a <br /> moderately sorted f quifer consists of cicaner <br /> y me to coarse sand that show <br /> depth) Ben s graded bedding (fine to coarse with <br /> P ) eath the B zone aquifer is stiff clay that extends from approximately 27 feet <br /> bgs to 40 feet bgs The original five monitor wells did not encounter groundwater in the <br /> A zone aquifer when initially drilled and sampled Depth to water measurements taken <br /> between 1993 and February 1996 indicate that the A zone aquifer was dry (depth to water <br /> greater than 17 feet bgs) MWl through MWS are screened across both the A and B zone <br /> aquifers Sometime after February 1996 depth to groundwater measurements indicated <br /> that groundwater was in contact with the A zone aquifer, see Table 1 <br /> The groundwater in the vicinity of the site is semiconfined Groundwater elevation at the <br /> site vanes from a wet year high of 7 feet bgs (silty clay formation above the A zone) to <br /> about 22 - 23 feet bgs (B zone) during the previous drought period Groundwater flow <br /> direction in the A zone at the site has generally been to the west since December 1997 <br /> The B zone shows a similar flow direction, which would be expected due to the <br /> connection between zones at wells MW1 through MW5 <br /> Groundwater ,samples were obtained from all active wells associated with 1876 Country, <br /> Club Blvd during this quarter (May 22, 2003) As requested by San Joaquin County <br /> Health, WEGE and Advanced GeoEnvironmental, Inc (AGE) coordinated to obtain <br /> depth to water and groundwater samples on the same date WEGE monitored and <br /> sampled wells associated with the Sanchez Property, 1876 Country Club Boulevard and <br /> AGE sampled and monitored wells associated with Country Club Food and Fuel, 1856 <br /> Country Club Boulevard Figure 3 - Site Base Map has been expanded to show the <br /> relative positions of the Country Club Food and Fuel wells to the Sanchez Property wells <br /> Field notes from site monitoring and sampling can be found in Appendix A <br /> April 23, 2003 Load, haul and dispose of 638 tons of gasoline <br /> contaminated soils derived from over-excavation at the site <br /> to Forward Landfill, Manteca, CA <br /> May 22, 2003 Monitor and sample groundwater monitoring wells <br /> associated with the Sanchez Property <br /> DEPTH TO WATER MEASUREMENTS <br /> Depth to water was measured at all active wells on May 22, 2000' The measurements <br /> were made from the surveyed elevation at the top of casing at each well using an <br /> electrical air/water interface probe (Table 1) No free product or product sheen was <br /> observed in any of the monitor wells Table 1 also presents the Depth to Water <br /> measurements obtained from wells located at Country Club Food and Fuel Charts have <br /> 4 QM 2nd 2003 <br />
