One sample will be collected from each of the four sidewalls <br /> and two samples will be collected from the floor of the excavation. The samples will be <br /> analyzed for total concentrations of copper and lead. <br /> Task 3B: Trench Area <br /> Based on the length of t4ie trench, six soil samples will be collected to verify the removal of <br /> petroleum hydrocarbon impacted soil. Two samples each will be collected from each of the <br /> two sides, and bottom. In addition, one sample will be collected from the bottom of the drain <br /> excavation. The seven samples will be analyzed for total extractable petroleum hydrocarbons <br /> (TPH-diesel). <br /> Task 3C: Teepee Area <br /> Once the stockpile and teepee area soil are removed, three soil samples will be collected to <br /> verify the removal of metal impacted soil and confirm that petroleum hydrocarbons have not <br /> leached from the stockpile into the underlying soil. Each sample will be analyzed for total <br /> concentrations of copper; lead, and zinc; and for TPH-diesel. <br /> Task 4: Disposition Sampling <br /> Task 4A: Burn Pit Area <br /> Based on the potential for the metals to have been relatively localized, the separation of <br /> overburden from potentially impacted soil, and the cost/liabilities of disposition of waste to a <br /> Class I hazardous waste facility; one set of screening samples will be collected from each <br /> stockpile. Each set will consist of four samples which will be composited by the laboratory <br /> into one sample. The two resultant samples (one per set) will be analyzed for total <br /> concentrations of copper and lead. <br /> Assuming the overburde;i stockpile results are negative and the impacted soil stockpili res.' <br /> indicate that the Soil will require disposition at a Class I facility, another set of samples will be <br /> collected from the impacted stockpile and sent to ChemWaste for profiling and the creation of <br /> a "waste stream." If the impacted soil stockpile contains designated (verses hazardous) <br /> concentrations, the already collected sample can be analyzed for acceptance into Forward. <br /> Task 4B: Trench and Tetepee Area <br /> Four samples will be collected from the soil generated from the trench, drain, and teepee area. <br /> The samples will be composited into one sample by the laboratory and analyzed for acceptance <br /> into Forward. <br /> FR8-92-222 Page 3 of 7 24-220182-800 <br /> Copyright 1992 FJeinfelder, line. <br />
