i <br /> FARR ASSOCIATES <br /> The jars will then be sealed, Iabeled and immediately placed in a chilled cooler for transportation <br /> to a laboratory. Proper chain-of-custody procedures will be followed during sample collection <br /> and delivery to the laboratory. <br /> Unless specified otherwise, a total of three composite samples will be created by combining four <br /> soil samples each. The three composite samples will be analyzed for TPH-g, TPH-o, TPH-d, <br /> BTEX, and total lead. Samples collected from drums that yielded high HNu readings during field <br /> screening will be analyzed individually. <br /> 3.1.3 Decontamination of Sampling Equipment <br /> All equipment will be decontaminated prior to use at the site and between sampling locations. <br /> Decontamination will consist of washing equipment with Alconox soap in deionized water and <br /> rinsing with deionized water. <br /> 3.2 Disposal of Drums and Drummed Material <br /> 3.2.1 Disposal of Water <br /> If the analyses yield concentrations within acceptable levels, then a letter will be written to the <br /> Director of Municipal Utilities in Stockton, California requesting a special permit to dispose of <br /> the water directly to the municipal sewer. Once the permits are obtained, a septic hauler will be <br /> retained to transport and dispose of the water. <br /> In the past, groundwater samples from the wells have typically yielded low to non-detect <br /> concentrations of TPH and BTEX. It is therefore believed that the samples will be acceptable to <br /> the City of Stockton. If, however, the composite samples yield concentrations unacceptable to <br /> the City, the individual samples used to create the composite sample will need to be analyzed. <br /> Drums of water not meeting the City's requirements will be sent to a treatment facility. Costs for <br /> the additional analysis and treatment are not included in this work plan. <br /> 3.2.2 Disposal of Soil and Drums <br /> After the soil analysis has been completed, the drums will be properly labeled, manifested and <br /> shipped to Forward Landfill (a Class 2, Subtitle D landfill) in Stockton for disposal. <br /> 3.3 Summary Report <br /> A brief report will be prepared and delivered to San Joaquin County PHS/EHD and the Union Ice <br /> Limited Partnership describing the results of the sampling and disposal activities. Copies of all <br /> laboratory analyses and disposal manifests will be included in the report. <br /> 3 <br /> uoionice,'proposa L doe <br />
