KEI-P87-049A <br /> May 18, 1987 <br /> Page 2 <br /> 1. 0 INTRODUCTION <br /> Kaprealian Engineering, Inc. (KEI) is pleased to submit this <br /> proposal for a preliminary subsurface investigation for the Mobil <br /> Terminal located on Navy Drive in Stockton, California. The <br /> proposed investigation will be conducted in accordance with the <br /> California Regional Water Quality Control Board (CRWQCB) Fuel <br /> Leak Guidelines. <br /> 2 . 0 SCOPE OF WORK <br /> Per our recommendations described in our report dated May 1, <br /> 1987, additional investigation is necessary to comply with the <br /> State and Local Regulatory Agencies regulation. Therefore, per <br /> the CRWQCB guidelines, KEI proposes to perform the work as <br /> outlined below: <br /> 2 . 1 Coordination with the Local Agencies <br /> 2 . 2 Installation and construction of three (3) monitoring wells <br /> as shown on attached sketch. <br /> 2. 3 During the well construction, soil samples will be collected <br /> at five foot intervals starting at a depth of ten (10) <br /> feet. Soil sampling will continue until the first water <br /> table is encountered. <br /> 2 . 4 Three monitoring wells (two inch diameter) will be <br /> installed. The monitoring wells will be observed for free <br /> product, sheen and odor. Water samples will be taken and <br /> analyzed for total hydrocarbons, Benzene, Toluene and Xylene <br /> per the CRWQCB guidelines. <br /> 2 . 5 Results of the samples will be evaluated as to the current <br /> and potential impact on the ground water. <br /> 2 . 6 A technical report will be submitted within thirty (30) days <br /> of completion of the soil and water sampling. The report <br /> will document the field work performed, chemical analyses of <br /> soil/groundwater, conclusions and recommendations. <br />
