. Purging was conducted at pump rates adjusted to prevent the wells from being drawn <br /> down more than 20% of their original well volumes Dedicated polyethylene tubing was <br /> used for filling three 40 ml VOAs, with no headspace, from each well The VOAs <br /> contained 0 5 ml HCl acid as a preservative <br /> The samples were delivered with accompanying chain of custody documentation to KCFF <br /> Analytical LLC (DHS certified #2236) The laboratory analyzed the water samples from <br /> each monitor well for concentrations of TPH-G, BTEX and the five oxygenants using <br /> EPA method 826013, see Appendix B -Laboratory Report <br /> DISPOSITION OF WASTEWATER <br /> 170 gallon of groundwater and fluids produced during Quarterly Sampling (January 14, <br /> 2005) was stored on site in a 250 gallon capacity poly tank until later transferred to a <br /> truck mounted 350 gallon poly tank and transported for disposal by Western Geo- <br /> Engineers to InStrat, Inc in Rio Vista for disposal on March 10, 2005 The previous <br /> water treatment system was dismantled and the water carbons units are awaiting profiling <br /> for disposal by U S Filter, Westsates Carbons, see water disposal receipt in Appendix C <br /> RESULTS OFF QUARTERLY GROUNDWATER MONITORING <br /> GROUNDWATER GRADIENT AND FLOW DIRECTION <br /> A-ZONE- 1876 AND 1856 COUNTRY CLUB BOULEVARD <br /> Figure 4A uses the new survey elevations supplied by Morrow Surveying survey dated <br /> September 24, 2004 Figure 4A shows the groundwater elevation gradient and flow <br /> direction (January 14, 2005) determined from depth to water measurements at thirteen <br /> wells associated with the Sanchez Property and the four wells associated with Country <br /> Club Food and Fuel The current groundwater gradient shows a flow direction to the <br /> northwest at a gradient of 0 0022 ft/linear ft (MW5 to Sanchez MW9A) <br /> RESULTS OF CERTIFIED ANALYSES OF GROUNDWATER SAMPLES <br /> MONUOR WELLS <br /> Sanchez monitor wells MW2, MM3, MW4, MW5 and MW 10 along with Country Club <br /> Food and Fuel (CCFF) penetrated both the A and B zones Contaminants found in these <br /> wells would mix with the groundwater of both zones <br /> 5 Sanchez QM l st 2005 <br />
