Mr. Tim P. Becker 2 June 17, 1988 <br /> o Obtained two soil samples, SS-1N and SS-1S to verify, by laboratory <br /> analysis, the observed lack of hydrocarbons in the tank pit. The <br /> ' sample was analyzed for total volatile petroleum hydrocarbons (TVPH) , <br /> lead (Pb), ethylene dibromide (EDB) , and benzene, toluene, and xylene <br /> (BTX) . The sample locations are shown on Figure 2 and the sampling <br /> ' methodology and preservation techniques are described in Attachment A. <br /> Laboratory reports are provided in Attachment C. <br /> o Backfilled the tank pit with clean soil and compacted the backfill to <br /> ' minimize settling. <br /> Concluding Remarks <br /> From field observations and laboratory analyses, the following statement <br /> can be made about the soil conditions at the tank site in Lodi : <br /> ' o Laboratory analyses resulted in nondetectable levels of TVPH, EDB, <br /> BTX, and lead in the soil below the gasoline tank (Tank A) . This <br /> confirms the observed lack of contamination noted during tank removal <br /> operations. <br /> ' Based on the above stated condition, Canonie recommends that no additional <br /> work be performed at the site in connection with the tank removal . <br /> In accordance with CAC Title 23, Chapter 3, Water Resources Control Board <br /> Subchapter 16, Underground Storage Tank Regulations and the San Joaquin <br /> County Underground Storage Tank Removal Procedures governing underground <br /> ' storage tank removals in Lodi , California, copies of this letter and <br /> attachments should be forwarded to the following agency: <br /> Mr. Harlan Knoll <br /> ' San Joaquin Local Health District <br /> 1601 East Hazelton Avenue <br /> P.O.
