_L4 judicious use of State Cleanup Funds, the volume of work and the remediation that has taken place at the site, it can not be fairly said that we are recalcitrant. Further you were not informed of the transfer in lead agency that occurred in March of 2003. A brief history maybe helpful. In November of 1996, Mr. Frank Guinta purchased the property at a public foreclosure sale from Mr. James Ramsey and Mrs. Marilyn Ramsey. In February 1995 and prior to Mr. Guinta's purchase of the site, Bank of Stockton hired a consultant to conduct an investigation of the site found indications of a gasoline release. Additional borings were made between April of 1997 and May 1998 confirming the presences of TPHg, diesel (as TPHd), benzene, ethyl benzene, toluene, xylenes, and fuel oxygenates including MtBE and TBA. In June 1998, Guinta hired Remedy Construction to remove two 10,000-gallon diesel USTs and four 10,000-gallon gasoline USTs from the site. In April of 1999, Guinta retained the services of Aqua Science Engineers, Inc. to proceed with the site clean up. By December 1999, forty-six drinking water wells were identified within a half-mile of the site. In July August and September 2000, groundwater from thirty-eight domestic and two irrigation wells were sampled. Analytical results revealed that MtBE well had impacted ten domestic and one irrigation well. Upon learning of these test results Mr. Guinta, on his own, began immediately began delivering, personally, bottled water to the affected neighbors. In August 2000, both a groundwater extraction well and one air sparge well were installed to conduct a pilot stud for the feasibility of using these technologies at the Site. In September 2000, one additional extraction well was installed; three piezometers wge,converted to extraction wells and the groundwater "pump and treat" system began operating at the Site as an interim remedial action. In September 2000, the affected domestic wells were disconnected from the residences. Temporary bulk water supply tanks were installed at each home and Mr. Guinta initiated water delivery. In January 2002, the bulk water supply tanks were replaced by.wellhead treatment systems consisting of two granulated activated carbon (GAC) units connected inline between the well and the residence. In February 2002, pursuant to an approved Remediation Action Pan (RAP), the ground water extraction system was turned off, in conjunction with the startup of a Soil Vapor Extraction /Air Sparge (SVE/AS) System. In January 2003, the SVE/AS System was turned off to allow the site to "heal". The system was turned back on in April 2003 and continues to operate to date.
