DEPTH TO WATER MEASUREMENTS <br /> Depth to water was measured at all active wells on July 15, 2004 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 The top of <br /> casing elevations for the Country Club Food and Fuel wells were adjusted in height by <br /> 2 9 feet (the most common elevation change found between the old survey and the new <br /> survey of the Sanchez wells) Charts have been developed to show the elevation changes <br /> with time for Sanchez wells MW1, MW2, MW3, MW4 and MW5, see Appendix B <br /> Western Geo-Engineers surveyed the top of casings for temporary piezometers on <br /> February 5, 2003 using level and rod <br /> COLLECTION AND CERTIFIED ANALYSES OF GROUNDWATER SAMPLES <br /> WEGE personnel collected quarterly groundwater samples from thirteen monitor wells at <br /> the site on July 15, 2004 See Appendix A for QA/QC, details, methods, procedures, <br /> abbreviations, and acronyms used in sampling and analysis <br /> Following depth to water measurements, WEGE used a truck mounted electrical <br /> submersible (Reda Flow 2) adjustable speed pump and dedicated 5116 inch diameter <br /> polyethylene tubing to purge each well of three volumes of water and until the water <br /> parameters, pH, conductivity and temperature stabilized <br /> 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 weir, delivered with accompanying chain of custody documentation to KIFF <br /> Analytical LLC (DHS certified #2236) The laboratory analyzed the water samples from <br /> each monitor well for concentrations of TPH-G, BTEX, the five oxygenants, 1,2 <br /> Dnchloroethane and 1,2 Dibromoethane using EPA method 8260B, see Appendix C - <br /> Laboratory Report <br /> DISPOSITION OF WASTEWATER <br /> Groundwater and fluids produced during well installations and development (June 22 - <br /> 28, 2004) was processed through 4, in series, water carbon units, a sample of the treated <br /> water was obtained This water(170 gallons) was temporarily contained on-site in a 250 <br /> gallon poly tank Sample results showed this water could be discharged to the sanitary <br /> sewer, it was discharged to sewer on September 24, 2004, see September 2004 Sewer <br /> Discharge Report, Appendix D Groundwater purged during the July 15, 2004 sampling <br /> 7 Sanchez QM 3rd 2004 <br />
