INFORMATION SHEET <br /> ORDER NO. R5-2003-XXXX <br /> SHORE TERMINAL SERVICES 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 was released. Investigations in August 2002 and March 2003 e <br /> delineated the extent of the petroleum pollution. Petroleum pollution is limited to the A v <br /> water bearing zone which is about 5 feet below ground surface. <br /> The enhanced bioremediation pilot study proposes to extract groundwater from two <br /> extraction wells at the downgradient extent of the area with petroleum pollution, or <br /> treatment zone. The extracted groundwater will be piped to a 300-gallon storage tank at <br /> the upgradient end of the treatment zone and then mixed with PetroZyme, which is a <br /> proprietary product that contains microbes that produce enzymes capable of catalyzing <br /> the breakdown of petroleum hydrocarbons and NutriMax,which is a nutrient mix that <br /> contains nitrogen,phosphorus, and potassium to promote microbial growth. The treated <br /> groundwater is then injected via three injection wells at the upgradient end of the <br /> treatment zone by the Super Ox TM unit. The downgradient extraction and natural <br /> groundwater will pull the treated groundwater through the treatment area. <br /> This remedial process allows microorganisms to degrade petroleum pollution to carbon <br /> dioxide and water. <br /> DLL 8/1/03 <br /> 1 <br /> V <br /> e <br />
