Center St., Suite A <br /> Stockton, CA 95202 <br /> RE: Former Underg:uund Tanks at 9170 Thornton Road, County Health Site Code <br /> 2193 <br /> Dear Mr. Kleinfeld; <br /> As you requested, I have reviewed files related to the underground tank removed at the above <br /> referenced site, as well as the nearby 7-11 facility at Thornton Road and Waudman Avenue. <br /> In October of 1991, the San Joaquin County Environmental Health Division (EHD) issued a <br /> letter to Mr. Richard Northcutt notifying him of the filing of a contaminated site report for the <br /> former Walts Auto Repair at 9170 Thornton Road (APN 076-330-19). Also located on the <br /> parcel is the Ivy Motel (9172 Thornton) which is served by a shallow domestic well along <br /> Connie Avenue. In the letter, it was indicated that lab results of water samples from this well <br /> prompted EHD to review the results of soil sampling from beneath the former underground tank <br /> which was removed in September, 1987. <br /> The soil samples referred to included 8 discrete samples from 4 different locations beneath 2 fuel <br /> tanks and 2 small waste oil tanks. Samples were analyzed for B T EX, ethylene dibromide <br /> (EDB), PCB's, purgeable chlorinated hydrocarbons, total lead and total volatile petroleum <br /> hydrocarbons (TVPH). Analysis showed non-detectable levels for all analytes in all samples <br /> with the exceptions of 15 mg/kg and 3.1 mg/kg of TVPH beneath the two fuel tanks. The <br /> County Health District, in a letter to Mr. Doug Carter of the Board of Supervisors, dated <br /> February 24, 1988, stated: <br /> 11-05-87 Received soil sample results from 4 tank removals. All samples were 'non- <br /> detectable' for.petroleum hydrocarbons, except Tank #I sample had 15 ppm TPH (total <br /> HPL6n.RWl <br />
