The first boring, located in the area of documented soil <br /> contamination beneath the east end of the former diesel tank pit location, will be <br /> advanced by hollow stem augers to 50 feet below surface grade(bsg). Soil samples for <br /> analysis will be collected every five feet, and one grab water sample will be collected at <br /> final depth. The next four borings will be located to surround the first boring, and will be <br /> advanced to approximately 30 feet beg using a direct push methodology. Soil samples <br /> for analysis will be copected every five feet. The grab groundwater sample will be <br /> analyzed for total petroleum hydrocarbons as diesel (TPHd), TPH as gasoline, benzene, <br /> toluene, ethylbenzene and xylene(BTEX)and methyl tertiary butyl ether(MTBE). The <br /> soil samples will be analyzed for TPHd, and BTEX. <br /> The work plan did not include a site specific Health and Safety Plan. In a conversation <br /> with URSGWC it was understood that a copy of said plan would be provided to <br /> PHS/EHD prior to site mobilization. <br /> The work plan as outlined above is approved.
