Ruiz Grocery Store, 4491 West Durham Ferry Rd., Tracy, CA <br /> Dear Mr. Hartzell, <br /> This letter transmits .a copy of Clearwater's Groundwater Monitoring Report - Second Quarter 2001 for <br /> the referenced site. As you may recall, we discussed sampling the project again in April with the hopes <br /> of closing the project and abandoning the wells prior to road and shoulder work (now scheduled to <br /> begin on April 16) that might result in covering and/or damaging several wells. <br /> I received the most recent sampling results from the lab on Monday, April 9 and distributed these <br /> results via facsimile to the regulating agencies for rapid review. Your voice mail indicated you would <br /> be out from April 9 to the 13, so I contacted Ms. Cori Condon to request her review of the data given the <br /> compressed time line. Ms. Condon indicated that the data looked very favorable for closure, and <br /> verbally approved the destruction of the wells. Therefore, I will work with San Joaquin County to <br /> permit and accomplish well destruction by Friday, April 13. <br /> Even though the regulating agencies may likely issue .a letter requiring "no further action" in terms of <br /> investigation and clean-up of the former gasoline release at the site, Ms. Condon indicated that Ms. <br /> Ruiz may be required to test the Domestic Well for MTBE on a quarter-year basis, as part of her permit <br /> from San Joaquin County to operate the well. Ms. Condon indicated that she would be in direct contact <br /> with Ms. Margaret Logorio at San Joaquin County regarding this issue. <br /> If you have any questions regarding this project, please feel free to call me at (510) 893-5160. <br /> Sincerely, <br /> Clearwater Group <br /> Brian Gwinn, R.G. <br /> Chief Geologist <br /> enclosures <br /> CC., Ms. Lori Duncan, SJCPHS/EHD, P.O.
