San Joaquin Street <br /> Stockton, California 95201 <br /> Subject: Soil Remediation Plan <br /> Escalon Packers Cannery - i <br /> 1905 McHenry Ave <br /> Escalon, CA <br /> Dear Ms. Turkatte: <br /> On behalf of Escalon Packers, Inc. , Geological Audit Services has <br /> investigated potential remediation alternatives for the six DOT <br /> drums of contaminated soil and three drums of decontamination water <br /> that are presently stored on site at the referenced address. These <br /> drums contain drill cuttings and steam-cleaning rinseate <br /> accumulated during the drilling of soil borings at the site in <br /> January and May 1992 . We have considered the following options: <br /> 1) Using the contaminated soil to produce asphalt, for on-site <br /> use. <br /> 2) On-site bioremediation of soil, and off-site disposal of <br /> the water at a licensed facility. <br /> 3) On-site ozone treatment of soil and water. Ozone remediation <br /> is a developing technology that has been used successfully to <br /> remediate both soil and water in Florida and elsewhere. <br /> 4) Off-site disposal of soil and water at a licensed facility <br /> (Forward Landfill) . <br /> 5) Off-site disposal of the water, and on-site disposal of soil <br /> in the former concrete heating vault, followed by encasement <br /> of the soil in concrete. <br /> It does not appear that appropriate vendors are available at this <br /> time to initata remediation alternatives 1 and 3 . Our efforts to <br /> identify suitable contractors to perform the remediation have been <br /> unsuccessful. <br /> Alternatives 2 and 4 could require testing of soil and water <br /> samples to self-certify that the contaminated materials are non- <br /> hazardous. Due to the small. volume of material, these alternatives <br /> are relatively expensive,, and would require either that the <br /> contaminated soil be hauled to another site for disposal or <br /> periodically treated and sampled before on-site: disposal. <br /> Therefore, we recommend implementation of alternative 5. <br /> Environmental Services•Hydrogeology•Geotechnical Services <br />
