Original analysis of the soil below the storage tank indicated <br /> that some gasoline contamination may be present. The following is a proposed work plan for the <br /> investigation_ <br /> 111E SILTE INVESTIGATION WORK PLAN <br /> We propose to place a soil boring at or near the center of the excavation of the removed underground <br /> storage tank. Soil samples will be taken at ten foot intervals by a split spoon sampler from a hollow <br /> stern auger. Each sample will be logged for soil classification and marked far identification. <br /> Each soil tube will be capped with a layer of aluminum foil secured by plastic caps, sealed with duct <br /> tape,labeled for identification,and stored on ice for transport to the laboratory. Soil samples will be <br /> transported under a chain of custody to Sherwood Labs of Hilmar, Ca. for analysis. Samples will be <br /> analyzed per EPA Methods 8020(BTEJ),(MTBE), and 5030/8015"TPH Gasoline. <br /> If the soil samples indicate that the contamination is at or near the existing water table, a 2"PVC <br /> monitoring well will be installed. The monitoring well will be purged and sampled as per standard <br /> practices of the industry. <br /> Please address any questions,corrections,or additions to Ery Rifenburg,Foothill Engineering, phone <br /> 209/368-9381 <br /> Respectfully submitted, <br /> p�ISFESS�p <br /> Fo n eery <br /> � m <br /> No. <br /> r Rifen urg P Exp, <br /> cc:Dr. Delph o 'at,�;r� <br />
