ed from this excavated material. Also, soil samples were col- <br /> lected at the bottom of the pit along the side walls in seven <br /> locations. These soil samples were submitted to H.C. Labcrato- <br /> ries for analysis. <br /> A composite of the sixteen composites submitted to B.C. Laborato- <br /> ries was analyzed for soluble and total metals. The analyses <br /> showed metals concentrations which ranged from non-detectable to <br /> below the regulatory criteria set forth by Title 22, Article II <br /> of the California Code of Regulations for hazardous waste. <br /> On October 2, 1990, a composite from each sail pile (six) were <br /> collected and submitted to Sequoia Analytical Laboratory. A <br /> single composite of these six samples was analyzed for toxicity <br /> by 96-hour static bioassay. The resulting LC-50 was greater than <br /> 1,000 ppm which classifies the soil as non-hazardous. <br /> Based on these analyses, the soils were self-certified as non- <br /> hazardous and transported to the BJJ Company facility at 2431 <br /> East Mariposa Road, Stockton, California. The soils have been <br /> stockpiled on 6 mil plastic pending approval of a remediation and <br /> disposal plan. The results of the excavation and sampling pro- <br /> gram were presented in a report dated November 15, 1990. A <br /> workplan for investigation of potential groundwater contamination <br /> was included in the November, 1990 report. <br /> The pit was subsequently backfilled with claan sandy soil which <br /> was compacted to 95% maximum compaction at optimum moisture. A <br /> new asphalt road was constructed over the top of the former <br /> excavation. Apparently during the paving of the area, monitoring <br /> well MWl was covered with asphalt and is currently inaccessible. <br /> 2.0 SUMMARY OF TECHNICAL DATA FROM THE PRELIMINARY REPORT <br /> 2.1 Name and address of site, tank owner and contact person: <br /> Site Location: <br /> H.
