(DCI) at Woodward-Clyde <br /> Consultant's office in San Diego, California. BCI described their <br /> ex-situ bioremediation technology which involves application of a <br /> mixture off cultured natural soil bacteria and enzymes , liquid <br /> fertilizer, j� and surfactant to stockpiles ,of petroleum hydrocarbon <br /> contaminated soil. They asserted that following application of <br /> their liquid mixture, the petroleum hydrocarbon contaminated <br /> stockpile could be covered and the contaminants would biodegrade to <br /> low levels without any further maintenance (e.g. tilling) . <br /> Pilot Test <br /> •f <br /> A pilot test of BCI 's bioremediation technology was conducted at <br /> the Shewey 1, Environmental Remediation Facility (low temperature <br /> thermal desorption rotary kiln) in San Diego, California. <br /> Approximately 50 cubic yards of soil contaminated with motor oil <br /> was used for the pilot test. This soil had been run through the <br /> rotary kiln; however, it still contained an average total petroleum <br /> hydrocarbon�[ (TPH) concentration of 554 mg/kg (EPA 418 . 1) . The <br /> cleanup level established for this soil was 100 mg/kg TPH. <br /> On Novemberll10 , 1993 , four baseline samples were collected from <br /> this 50 cubic yards of motor oil contaminated soil . The soil <br /> "Prevenfiorr Comes First" <br />
