DETAILS OF WORK PERFORMED UNDER WORKPLAN DATED JULY 17, 1990 On October 49 1990, Spectrum Exploration moved onto location and rigged up over Bore Hole #1, (refer to Plate VI.) Properly prepared brass tubes with end caps and plastic were delivered to the site by an FGL Environmental employee, and was received under proper chain-of-custody by W. J. Hunter, Registered Geologist in charge; (refer to Exhibit B for details., ) Boring commenced at approximately 9: 15AM using 3 1/4" ID 6" flights. Soil samples were taken utilizing clean 2" diameter brass tubes placed in an 18" split-spoon sampler which was driven into the soil beneath the current auger depth. The brass tubes were briefly described, sealed, labeled, and placed on ice by Mr. Hunter. The split-spoon sampler and associated equipment was thoroughly cleaned using TSP prior to each use. Cuttings were examined and stored adjacent to the rig as necessary. Samples were taken at the following depths, as proposeu in the Workplan - 1 ' , 5' , 10' , 15' , 20' , 25' , 30' , 35', Ax 40' , the total depth of bore Hole #I. There was no odor detected in the drilling returns or core samples, and no free product was noted in water. Upon completion of operations, the rig was mewed to bare hole #2, ' which had been proposed to be drilled in the bottom of the excavation; (refer to Workplan for details. ) However, because of the weight of the rig and the potential for caving, the rig was moved about 9 feet east: of the edge of the pit. The same procedure was followed as in borehole #1, and samples were taken at the same depths. Again, no odor was detected or free product observed. The drilling rig wa.5 moved to location #3, and the same procedure was followed as in #1 & #2. No,odor or free product was noted. Activities were suspended for the day; the boreholes were properly grouted from the bottom to the surface under the direction of the EHD. representative. The preserved samples were transferred under chain of custody to field personel from FGL Environmental for transport to-the lab for analysis. The remaining unused brass tubes were stored an ice in a locked room on site, for use the following day. The rig arrived on location on October 5, 1990 at 8:30 AM. After discussion with the geologist--in-charge, it was decided to drill borehole #5 ahead of #4. The rig was moved into the open field to the west of the property, and positioned as shown an Plate VI. The same procedure as used in the other borings was follower!, with cores taken at 5' intervals from S' to 40'. No core was taken at the 1 ' depth; the location was in an empty field which had been farmed in prior years, and sample results would not have been relevant. The rig was then moved back on the property, and borehole #4 was drilled and sampled using the same procedure as the other hobs, 2
