<br /> for copying. With a grnured level of plus 25 ' and a water
<br /> level of plus 15 ' , groundwater could be found 10' below the :;
<br /> surface at the present time at the project site. As noted in
<br /> the appended report, the water levels shown on the County
<br /> maps is the hydrostatic head level of the aquifers i:t 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 1986. These
<br /> data indicate that conditions were about the same as in 1990
<br /> with, a water level of about plus 1S' .
<br /> Figure 3 shows the water levels for the spring of 1953, a
<br /> recent year of high water levels. This map =haws that the
<br /> groundwater head was about plus 20' at that time, indicating " >'
<br /> that it would rise to within 5' of the surface.
<br /> These data show that the v2dose zone, if it, is in hydraulic
<br /> connection with the aquifers below about -100' , where most
<br /> of the local water wells are completed, could have been ex-
<br /> tended by about 5' between 1983 and 1190, from 5' below the
<br /> surface to about lo' 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 testwells anal 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 EHD.
<br /> PROPOSED WORK
<br /> A generalized safety operations plan for the project has
<br /> 1
<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 surveyed 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
