with the drums. The backhoe was positioned on the north side of the area to be excavated, and began removing soil. It was temporarily placed next to the site, and periodically moved to the east side of the property and placed on black plastic. Soil contamination was heaviest immediately beneath the removed pump islands, although there was no evidence of free product. As excavation continued, visible evidence of contamination decreased significantly below 10 feet on the north, east, and south sides. However, it was still present on the west wall next to the building. Because It was not possible to excavate beneath the foundation, the extent of the soil plume to the west cannot be accurately estimated. Sediments consisted primarily of brown to dark gray plastic clay interbedded with greenish-grey clay and minor sand lenses. It was difficult to identify contaminated areas because of the color of the native clay. Tan to light brown clay was encountered on the bottom and three sides of the excavation. It was fairly firm, slightly moist, with very few sand grains. It did not have any odor or signs of discoloration. The north end of the excavation encountered the pea gravel used to fill the hole occupied by the removed UST's. At a depth of 10' 6", groundwater began seeping into the hole. There was a slight scum on the surface, but no "rainbow" or sheen 4...• noted. The backhoe was repositioned as needed, and the final size of the exca- vation measured 17' x 8' x 12' deep. Prior to taking a water sample, the backhoe bucked was pushed into the muddy soil in the bottom of the pit to allow water to run into it. A hose from a vacuum truck was lowered into the bucket, and several gallons of muddy water was removed. A clean liter bottle provided by the analytical lab was lowered into the bucket and 4 voa's and a liter bottle of water were collected. Soil was removed from the bottom and the four sides of the hole with the backhoe bucket. Samples were taken from the teeth by the geologist in charge by pushing clean metal tubes into the soil; covering the ends with teflon tape and plastic end caps. Both ends were sealed with duct tape, the sleeves were labeled and were placed on ice pending transport to the laboratory. Refer to PLATE V for the locations of the soil samples and other details. Approximately 70 cubic yards of material was removed from the excavation. It was temporarily stored on the property. It was placed on, and covered with, black plastic. The excavation was filled with pea gravel and topped with road base. It has since been covered with asphalt. The preserved soil samples were transferred under chain of custody to the courier from Sherwood Labs. The geologist left the site at 1500 hours. 5
