JOAQU!N COUNTY <br /> Staff of the Regional Water Quality Control Board, Central Valley Region (Central Valley <br /> Water Board) reviewed 1 November 2010 Annual Report— Third Quarter 2010 (Annual <br /> Report) submitted by Advanced GeoEnvironmental, Inc. (AGE) on behalf of the Herman and <br /> Helen's Marina (H&H) located at 15135 Eight Mile Road in Stockton (Site). The annual <br /> sampling event was conducted during the third quarter, instead of the fourth, on a one-time <br /> basis. <br /> Groundwater at the Site is polluted by two documented fuel spills. The first occurred sometime <br /> in the 1990s. A second gasoline discharge of unknown quantity occurred around <br /> September 2007 from an aboveground storage tank (AGT) in the vicinity of MW-2, the <br /> monitoring well closest to the AGT, and caused a distinct increase in the petroleum <br /> hydrocarbon concentrations in MW-2. Constituents of concern (CDCs) at the Site include total <br /> petroleum hydrocarbons as gasoline (TPHg), methyl tertiary butyl ether (MTBE), tertiary butyl <br /> alcohol (TBA), and tertiary amyl methyl ether (TAME). <br /> To clean up the pre-September 2007 spill, H&H conducted groundwater remediation by <br /> extracting groundwater from a 6-inch diameter extraction well (EW-1) and routing it through a <br /> granular activated carbon (GAC) treatment system.

H&H commenced <br /> groundwater extraction from the sump and routed the groundwater to the existing IRM <br /> treatment system. Due to dewatering of the sump, direct extraction was not possible between <br /> October 2007 and December 2008. Pumping from the sump was performed during the first <br /> quarter of 2009, and operation of the IRM ceased in 30 June 2009. Presently, no remediation <br /> is being performed at the Site. <br /> Groundwater monitoring and reporting requirements for the Site are set forth in Monitoring and <br /> Reporting Program (MRP) No. R5-2009-0833. A quarterly monitoring event, during which all <br /> Site wells were sampled, was conducted on 27 July 2010.
