INFORMATION SHEET <br /> ORDER NO. R5-2003-XXXX <br /> SHORE TERMINAL SERVICES <br /> STOCKTON TERMINAL#29 <br /> ENHANCED BIOREMEDIATION PILOT STUDY <br /> SAN JOAQUIN COUNTY <br /> Shore Terminal Services owns the bulk fuel terminal at 2941 Navy Drive in Stockton. <br /> Two separate gasoline releases occurred in March and April 2002. In June 2002, about <br /> 1,000 gallons of diesel were released. Investigations in August 2002 and March 2003 <br /> delineated the extent of the petroleum pollution. Petroleum pollution is limited to the A <br /> water bearing zone which is about 5 feet below ground surface. <br /> The proposed system will extract groundwater from two extraction wells screened in the <br /> A water bearing zone downgradient of the treatment area. The extracted groundwater <br /> will be piped to a 300-gallon storage tank at the upgradient end of the treatment zone and <br /> then mixed with PetroZyme,which is a proprietary product that contains microbes that <br /> produce enzymes capable of catalyzing the breakdown of petroleum hydrocarbons and <br /> NutriMax, which is a nutrient mix that contains nitrogen,phosphorus, and potassium to <br /> promote microbial growth. The treated groundwater is then injected via three injection <br /> wells at the upgradient end of the treatment zone by the Super OxTm unit. The Super <br /> OxTm oxygenation system takes the amended stream of water, oxygenates it to about 45 <br /> parts per million of dissolved oxygen, and injects it into the subsurface. The <br /> downgradient extraction and natural groundwater will pull the treated groundwater <br /> through the treatment area. There is plume capture to ensure that water quality objectives <br /> will not be exceeded beyond the project area. <br /> This remedial process allows microorganisms to degrade petroleum pollution to carbon <br /> dioxide and water. When the pilot study is completed, the amendments and byproducts <br /> shall not exceed baseline levels. <br /> DLL 9/24/03 <br />
