fl <br /> • Ii <br /> ETS ENVIRONMENTAL <br /> 1. 0 INTRODUCTION <br /> L <br /> This workplan has been prepared by ETS Environmental for <br /> Mr. Jerry Moore of Moore Petroleum. This workp 1 ar, represent s <br /> a preliminary investigation for the detection of hydrocarbon <br /> constituents in the subsurface prior to site renovatib�rj <br /> and/or a full scale site investigation. <br /> The site is located at 14800 W Frontage Road in Manteca, <br /> California. The site includes a fuel dispensing station and <br /> a convenience stere (Figures 1-1, 1-2) . Underground <br /> utilities are limited to the product lines running to ',the <br /> pumps. <br /> 1. 1 PURPOSE <br /> The purpose of this workplan is to outline the necessary <br /> phases of work necessary to determine the presence or absence <br /> of hydrocarbon contamination at the site. This workplan <br /> encompasses the preliminary work only, further investigation <br /> may be required should significant contamination be <br /> encountered. <br /> f <br /> 1. 2 SCORE OF WORK <br /> The following scope of work has been developed to: <br /> achieve the purpose of this investigation: <br /> 3 <br /> 1. Drill, soil sample, and log five soil borings to <br /> groundwater. Soil samples will be tested for hydrocarbon <br /> constituents using ERA method 8015 Modified for TPH. <br /> i <br /> 2. If contamination is encountered in the soil borings, <br /> complete up to three borings as wells. Wells will- be <br /> constructed to a total depth ten feet below groundwater <br /> with 2 inch PVC casing. Groundwater samples will be <br /> collected and tested for TRH and BTX using EPA methods <br /> 601 and 602. <br /> 2. Prepare a report summarizing findings, conclusions! and <br /> recommendations for further action, if necessary. <br /> 2. 0 PROPOSED WORKPLAN ! . <br /> The following workplan has been developed by ETS <br /> Environmental for site previously mentioned. All work will <br /> be conducted according to standard industry practice to <br />
