%.., %Mo� <br /> for copying . With a ground 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 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 fail of 1986 . These <br /> data indicate that conditions were about tl.e same as in 1_990 <br /> with a water level of about plus 151 . <br /> Figure W shows the water levels for the spring of 190-3 , a <br /> recert year of high water levels . This map shows that the <br /> groundwater heard was about plus 20 ' at -..at time , indicating <br /> that it would rise to within 5 ' of the sur�ace . <br /> These data show that the vadose zone , if it is in hydraulic <br /> ccrnection with the aquifers below about -100 ' , where most <br /> of the local water wells are completed, could have baen ex- <br /> tended by about S ' between 1963 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 rerort .
