s �.w ��1 ED PACIFIC COAST v MAR=2 2 1993 ENVIRONMENTAL HEALTH PRODUCERS PERMIT/SERVICES March 18, 1993 Ms. Linda Turkatte Environmental Health Division San Joaquin County Public Health Services P. O. Box 2009 Stockton, California 95201 Subject: Soil Excavation and Subsurface Investigation Results Report Pacific Coast Producers Lodi Cannery 32 Tokay Street, Lodi, California Dear Ms. Turkatte: Enclosed you will find a copy of the above-referenced report. The site work has been completed and the surface repaired to its original condition. The excavated soil has been properly disposed of at the Forward, Inc. landfill in San Joaquin County. In addition to the excavation of the petroleum hydrocarbon impacted soil, there was some indication of contamination which was located under the large concrete warehouse immediately adjacent to the excavation. Since it would not be possible to excavate under this structure without jeopardizing its integrity, you requested that we conduct a slant boring under the building where the impacted soil was located. In addition, you requested soil borings under the excavation to ascertain if any further impacted soil existed from the bottom of the excavation to 30 feet in depth. 1 The two soil borings under the excavation indicated no detectable total petroleum hydrocarbon (TPH), or the volatile constituents of concern (BTEX). However, the slant ; boring under the warehouse structure had an elevated TPH concentration (1500 mg/kg) f at 14.5 feet, with non-detectable levels of BTEX. No detectable levels of TPH or BTEX were found beneath this depth, in samples collected at 19.3, 24.1, and 29.0 feet. To summarize Section 4.0 (Discussion and Recommendations) of the report, we concur with the geologist's recommendations that no further action is required at the site because: 691 North Cluff Avenue P.O.
