• Mr. Collins, it was agreed that 4 of the composites would be analyzed for profiling purposes. The locations of all of the samples, including those taken from spoil piles, are shorn on PLATE VI. The composite samples, and those analyzed, are shown on the overlay. At the completion of sampling operations, the soil samples were transported under chain of custody to FGL laboratory with instructions to run the following tests= Soil maples from excavation - BTEX, TPH-G, total lead, and O&G, (418. 1.) on three samples. STLC for lead was later requested on some samples Soil sam _les fr_ga spoil piles -- BTEX, TPH-G, EPA 8540 , 8270 , & 6010 . Laboratory results of the samples from the excavation & trench area are summarized on TABLE fi; copies of the laboratory sheets and chain of custody are included az EXHI F The results of the analyzes from the spoil piles are not summarized, but the laboratory sheets are attached as EXHIBIT G • An analysis of the laboratory results from the excavation revealed that only the two samples from the west wall , (W-1 & W-Z, ) one from the north wall, (N-1 , ) and the northerly one from the trench area, (T-3, ) contained detectable amounts of hydro- carbon compounds Total lead was present in all samples, but at acceptably low levels. A review of the above work indicated that additional spoil removal from the west side and north end of the pit area would be sufficient to remove the small amount of remaining contamination. An Addendum to the workplan written by JTO was prepared by WJH on April 12, 1993, which proposed to remove an additional 5+ feet of spoil from the west wall and northwest corner of the existing excavation, and take appropriate soil samples A copy of that Addendum is included as FXBLBIT H. After approval by the County EHD, JTO moved in equipment on May 17, 1993, and began to load the contaminated spoil onto dump trucks, which transferred it to the Forward, Inc. disposal facil- ity. The trucks returned with clean fill, which was dumped into the hole. During this process, the excavator operator, Marty Thorpe, removed some of the remaining soil which had sloughed into the hole, and placed it on the ground for transport to Forward. Under the direction of the geologist, Mr. Thorpe removed about 5 feet of spoil from the west side of the excava- tion as far as the sidewalk on the edge of the property. Spoil was removed to a depth of about 20--22 feet, the physical limit of 6
