August 25, 2005 Completed water treatment system modification, tested system High pressure on carbons August 29, 2005 Located clogged line, discharge from carbons to Baker Tank Restarted pump and treatment system September 2, 2005 Baker Tank high level sensor shuts system off, 16,911 gallons treated and stored in Baker Tank September 21-23, 2005 Discharge treated water from Baker Tank to sanitary sewer September 29, 2005 Re-start pump and treatment system, discharge into Baker Tank September 30, 2005 Baker Tank high level sensor shuts system off, 16,623 gallons treated and stored in Baker Tank Groundwater pump and treatment system will be restarted once water samples obtained from the Baker Tank indicate that all permit conditions have been satisfied and the water stored in the Baker Tank has been discharged to the sanitary sewer Batch pump and treat will continue though the month of October, 2005, to verify that the modifications to the treatment system were successful in removing TBA, see Appendices C and F DEPTH TO WATER MEASUREMENTS Depth to water was measured at all active wells on July 15, 2005 The measurements were made from the surveyed elevation at the top of casing at each well using an electrical air/water interface probe (Table 1) No free product or product sheen was observed in any of the monitor wells Table 1 also presents the Depth to Water measurements obtained from wells located at Country Club Food and Fuel The top of casing elevations for the Country Club Food and Fuel wells were adjusted in height by 2 9 feet (the most common elevation change found between the old survey and the new survey of the Sanchez wells) Western Geo-Engineers surveyed the top of casings for temporary piezometers on February 5, 2003 using level and rod To determine the influence pumping from MW 10 had on surrounding wells Depth to water measurements were also obtained on September 28, 2005, prior to pumping, September 30, 2005, dust prior to terminating pumping and October 5, 2005, five days after terminating pumping from MW 10, see Table 2 and charts An average pump rate of 8 9 gpm was sustained while filling the Baker Tank (16,623 gallons) Depth to water measurements were obtained prior to initiating pumping prior to termination of pumping and five days after termination of pumping at MW10 from Sanchez wells MW2, MW3, MW4, MW5, MW8A, MW8B, MW10 and Country Club Food and Fuel wells MWI, MW2, MW3 and MW4, see Table 2 Sanchez wells MW6A, MW6B, MW7A and 6 Sanchez QM 3`d 2005
