regard to: failure to submit historic documentation of solvent disposal prior to 1985, failure to implement groundwater monitoring of the uppermost aquifer, and failure to implement a groundwater quality assessment. Several site characterization and assessment investigations have also been performed at the American Moulding and Millwork facility on West Lane for diesel, oil, heavy. metals, and Pentachlorephenol (PCP) contamination. Groundwater studies - have identified Napthalene and 2-Methylnapthalene in the shallow aquifer. Numerous UST's have been removed from this site, several of which have had reported soil contamination in the excavation. Other unauthorized release citations, for which subsequent documentation could not be located, include: Van de Pol Enterprises ( 3230 N. West Lane) for a failed precision test; U-Haul Stockton (2201 N. Wilson) for a failed precision test and leaks under fuel dispenser; and My Mini Mart (1756 N. Wilson) for leaks in UST vapor and vent lines and leaks around the UST filler tube. Six municipal wells and eighteen private wells exist in the vicinity of the project site. Kearney-KPF utilizes groundwater obtained from a deep well ( 200 feet) located on their facility for cooling water and plant operations. According to Department Of Health Services Remedial Action Order to Kearney-KPF, organic chemical contamination was detected in the California Water Service well 77 (located along West Lane approximately 1500 feet west of the site) in 1987. The potential source of the TCE was not identified. CONCLUSIONS The tank permit records on file with the Fire Marshal and San Joaquin County Department of Environmental Health indicate that the UST' s existing at the site have passed tank integrity tests. The one documented failed test of the 6,000 gallon unleaded gasoline tank was apparently caused by air remaining inside the tank and product line during testing. The tank passed a subsequent integrity test. -- The site investigation revealed several existing conditions which should be addressed: 1) the liquid-filled 55-gallon drum, labeled solvent, should be sampled to determine its contents and should be properly disposed of; 2) the large battery in the gravel storage area should be stored in a more appropriate place, or properly disposed of; and 3) the compressed-gas cylinder should be identified and properly stored, or disposed of; 4) the - white and yellow crystalline substance (possibly sulfur compound) should be identified through laboratory testing, if possible, and properly removed.
