A Groundwater depth Approximately 50'-60' <br /> B Soil removed 0 <br /> C Excavation history: On 2/17/05, Jim Thorpe, Inc. removed one (1) 12,000 gallon <br /> tank dual wall unleaded gasoline tank and one(1)2,000 gallon dual wall diesel fuel tank from <br /> the rear parking lot of 230 W. Elm street in Lodi, owned by the City of Lodi. The diesel tank <br /> Tested N/D. However, the BTEX portion for the diesel sample was over-looked and will be <br /> resampled the day of the overex. One sample for the gasoline tank tested high for MTBE <br /> (copy enclosed). The tanks were removed under the supervision of SJHS/EHD. Soil <br /> sampling was done by GeoAnalytical Laboratories. The excavations were filled in with <br /> materials on site and with imported pea gravel, road base and remain in that condition. <br /> 5. Re-excavation/resample: Due to the depth of ground water expected at approximately 50-60 <br /> feet, Jim Thorpe, Inc. and registered geologist Ground Zero feel the best method of clean up <br /> will be re-excavation. The excavation shall be at the north and of the original gasoline tank <br /> excavation. <br /> 6. Samples will be collected by a technician from Ground Zero and transported to Argon <br /> laboratory for analysis. A signed release of information authorization is attached. <br /> Actual excavation limits will be determined in the field based on conditions encountered. <br /> 7. The resulting re-excavation will be approximately 20'x20'x20' in depth. The amount of <br /> material removed will be approximately 150 cubic yards of clean pea gravel, soil and 150 <br /> yards of suspected soil. The suspected soil will be placed on 6-mil black plastic and covered <br /> with same. Soil disposition decisions can be made after amounts and contamination levels <br /> are ascertained. Samples will be taken from the middle of the length of each sidewall. <br /> Approximately 3 feet up from the bottom. At least one (1)floor sample below the high MTBE <br /> result. Four(4) samples will be taken from the spoils pile for characterization. Soil samples 3 <br /> will be analyzed for TPH-gas BTEX and Oxygenated additives. <br /> c <br />
