MW7B were non accessible, covered by Mission Blvd, repaving At a pump rate of approximately 9 gpm, pumping from the excavation well MW10 influences the Country Club Food and Fuel wells A second pump rate of 5 gpm is to be performed to determine the influence pumping has on surrounding wells in an effort to determine the proper pump rate that will only affect the groundwater plume associated with the Sanchez property Once the Baker Tank has been emptied this second pump test will be performed COLLECTION AND CERTIFIED ANALYSES OF GROUNDWATER SAMPLES WEGE personnel collected quarterly groundwater samples from thirteen monitor wells at the site on July 16 and 17, 2005 See Appendix A for QA/QC, details, methods, procedures, abbreviations, and acronyms used in sampling and analysis Following depth to water measurements, WEGE used a truck mounted electrical submersible (Reda Flow 2) adjustable speed pump and dedicated 5116 inch diameter polyethylene tubing to purge each well of three volumes of water and until the water parameters, pH, conductivity and temperature stabilized Purging was conducted at pump rates adjusted to prevent the wells from being drawn down more than 20% of their original well volumes Dedicated polyethylene tubing was used for filling three 40 ml VOAs, with no hcadspace, from each well The VOAs contained 0 5 ml HCl acid as a preservative The samples were delivered with accompanying chain of custody documentation to KIFF Analytical LLC (DHS certified 42236) The laboratory analyzed the water samples from each monitor well for concentrations of TPH-G, BTEX, the five oxygenants and lead scavengers 1,2 DCA and 1,2 EDB using EPA method 8260B, see Appendix B - Laboratory Report DISPOSITION OF WASTEWATER 150 gallon of groundwater and fluids produced during Quarterly Sampling (July 16 and 17, 2005) was contained on site in three 55 gallon drums for later discharged through the groundwater treatment system for disposal to sanitary sewer The water treatment system consists of five in series activated water carbon units that contain approximately 180 lbs of activated carbon each, with a 150 gallon capacity aeration tank situated between the #2 and 43 water carbon units After treatment through the 45 carbon unit the treated water is discharged into a 22,000 gallon capacity Baker Tank for sampling prior to discharge to sewer, see section on water treatment 7 Sanchez QM 3`d 2005
