I <br /> 3 depicts the proposed approximate location of the proposed groundwater monitoring <br /> wells. <br /> Soil samples will be collected in brass or stainless steel sleeves,labeled, stored in-a <br /> cooler with bagged ice,.and transported to a California-certified environmental laboratory <br /> under chain of custody protocol for analysis. The samples will be analyzed for total <br /> petroleum hydrocarbons as gasoline(TPHg)and diesel (TPHd)benzene, toluene; ethyl j <br /> benzene,xylene(BTEX),methyl-tertiary butyl ether(MTBE), and oxygenates using EPA <br /> Method 826013,and CAM 17 Metals. <br /> Prior to sampling,monitoring wells will be purged to remove stagnant casing water from <br /> the well that is not representative of aquifer conditions. Wells will be purged by <br /> removing the traditional three casing volumes prior to sampling. Groundwater samples <br /> will be analyzed for total petroleum hydrocarbons as gasoline(TPHg),benzene,toluene, <br /> ethyl benzene,xylene(13TEX),methyl-tertiary butyl ether(MTBE), and oxygenates <br /> using EPA Method 826013,Total Dissolved Solids (TDS), CAM 17 Metals, and a water <br /> quality analysis(redox potential, suspended solids,and total hardness). <br /> 5.1 Waste Management <br /> Any soil cuttings generated during drilling activities will be placed in DOT-approved <br /> drums and labeled appropriately. The soil and water will be stored onsite for disposal <br /> pending analytical results obtained from assessment activities. <br /> 6.0 REPORTING <br /> At the completion of site activities,and after the laboratory analytical data has been <br /> received, ERG will prepare a report describing the sampling procedures, laboratory <br /> analytical data,and test findings. The report will contain recommendations, as <br /> appropriate, for additional work that might be necessary. <br /> 7.0 REFERENCES <br /> Secor International Incorporated,Additional Site Assessment Report, Joe's Travel Plaza, <br /> June 27, 2006. <br /> Secor International Incorporated, Quarterly Groundwater Monitoring Report, Second <br /> Quarter 2006(April through June).foe's Travel Plaza, August 25, 2006 <br /> I <br /> i <br /> Environmental Remediation Group Page 4 Site Assessment Work Plan <br /> Project No.0406 Joe's Travel Plaza <br /> � 1 <br />
