north end of the former tank site, one at 14' bgl from the south end, and the 3rd one at 6' bgl from the east side, adjacent to the BJJ Co. property line. A composite sample was also taken from the removed spoil pile, which was temporally stored on the northwest side of the excavation. The samples from the north side (HC-1N, ) and the south side (HC-2S, ) were analyzed for BTEX, TPH--G, TPH-D, total lead, and priority polutants The sample from the east side (HC-3E, ) was analyzed only for TEPH. The composite sample from the spoil pile was tested for BTEX, TPH-G, TEPH, andtotal l ead Laboratory results revealed that BTEX & volatile organics were below detection limits in all samples, but TPH—GG_,_TPH-D, motor e er to ozl , and total PATE VI The removed spoil was returned to the hole pending further work. _EXHIBIT—E includes copies of County EHD field notes during the investigative work, and EXHIBIT G contains copies of the lab results On November 19 , 1991 , Geological Audit Services, Inc. submitted a workplan to the County EHD for excavation & removal of he contaminated soil from the site; (refer to EXHIBITF_ ) That workplan was not implemented. • In June, 1992, Wm J. Hunter & Associates, (WJH, ) were retained by Husky Crane to review & analyze the prior work, and prepare a workplan for delineating-the vertical & lateral extent of the contamination encountered during the work in October, 1991 . The site of the removed UST' s is immediately adjacent to the Husky Crane-BJJ Co property line as shown on PLATE VI As mentioned earlier, an observation well has recently been placed on BJJ property to monitor possible groundwater contamination caused by a 3500 gallon fuel tank which is located beneath a building and could not be removed. Soil borings beneath that tank showed significant levels of contaminants, and a water sample taken from the monitoring well in Dec e b o in Laboratory analyses of water samples taken from that well in 1994 were be detection liflu-tri" indicating that the hydraulic gra- dient may be to the west-southwest at that location. For that reason, an additional monitoring well has been permitted on the property southwest of the buried tank to verify that belief. Besides the existing UST, there were two (2) above-ground gaso- line tanks on the BJJ site about 50 feet northeasterly from the location of the removed tanks on the Husky Crane property. Those tanks were recently removed and replaced with UST' s in the same location. Details of that work have not been reviewed During investigative work conducted in 1991 at Husky Crane, • contamination was noted on the wall of the excavation abutting 4
