As noted in <br />the appended report, thr water levels shown on the County <br />maps is the hydrostatic head level of the aquifers in the <br />area and does not necessarily represent the level that water <br />might either be found or not found if these aquifers are <br />separated from the near surface deposits by aquicludes. <br />Figure 2 shows the water levels for the fall of 1985. These <br />data indicate that conditions were about the same as in 1990 <br />with a water level of about plus 151. <br />Figure 3 shows the water levels for the spring of 1983, a <br />recent year of high water levels. This map shows that the <br />groundwater head was about plus 20' at that time, indicating <br />that it would rise to within 5' of the sur-Zace. <br />These data show that the vadose zone, if it is ih hydraulic <br />connection with the aquifers below about -1001, where most <br />of the local water wells are completed, could have been ex- <br />tended by about 5' between 1983 and 1990, from 5' below the <br />surface to about 10' below the surface. This writer believes <br />that to be true for the general area; however, local <br />conditions at the excavation site could be different. <br />CURRENT STATUS <br />The site is as described in the attached report. No further <br />on-site work has been done. Bids have been received for the <br />boring of test wells and permits for these wells, are being <br />prepared for submittal at the time of this writing. On --site <br />activities cannot be started until this report of planned <br />operations has been approved by the £HD. <br />PROPOSED WORK <br />A generalized safety operations plan for the project has <br />been prepared and will be submitted along with the permit <br />applications. The drilling contractor, Sprectrum Exploration <br />Co., is expected to supply all necessary safety equipment <br />for their crew and to have their own site-specific plan. <br />Water Level and Direction--of-Flow Determinations <br />Figure 4 is a site map showing the location of the property <br />and various pertinent features. The is not a aurveyed map, <br />however it was adapted from the owner's property map and it <br />should be accurate. <br />The object of the work plan is to investigate the vadose <br />zone and the water table below to determine if either has <br />been contaminated by gasoline leaks from the former <br />PA <br />
