page - slightly muddy water were recovered and the well bailed dry. Samples were taken after the well had sat for about 3o min. and had partially recovered. pH was 4.59 and Temp. 62 de- grees F. Well No. 2, the southerly well near the entrance ramp to the pit, was bailed and sampled last. Water was located at 27.55' and well bottom at 33.45 ' from toc. 4.8 gallons of fairly clean, reddish tinged water was recovered before bailing dry. 5 times water in the hole would be about 5 gallons. pH was 5.27 and Temp. 64 deg. F. Samples were taken after the well water level had partially recovered. Operations were completed at 1 :45 PM. On April 14, 1990, Richard Thorpe and a surveyor re- established well head elevations on all wells. These new elevations are used below. An assummed elevation of 50' was used as a base elevation, based upon a steel marker in the blacktop entrance, and a HSGs Quad topographic map. RESULTS OF TESTS OF MONITORING WELL WATER As Specified by DHS Table 1 : MW 1: TPH-Diesel ND 0.50 mg/1 EPA 8015 MW 2: TPH-Diesel ND 0.50 mg/l EPA 8015 MW 3: TPH-Diesel ND 0.50 mg/1 EPA 8015 The Caaonie Labs report is appended. These tests, along with all previously reported, show that the groundwater had not been contaminated by the leaking tank. WATER SURFACE AND SLOPE VPW QfW,y Figure 1 herein was taken from the Groundwater Technology Report of 5/25/88. An almost flat water table is shown. Differences as small as these do not necessarily represent a regional slope direction at all . These data could be rep- resentative of the area, but owing to the lack of gradient found, one can't be sure. Table 2 These data are a tabulation of the measurements in the text above. A correction to a common elevation (50'assummed at driveway) has been made.
