0 -2- <br /> 1 <br /> i <br /> I mentioned that when a new well is drilled, many homes have muddy <br /> watter for a few days. To him, this indicated that water moves very <br /> quickly through our bedrock, thus increasing the chances of pollution. <br /> Based on the figures from my well (a 20 foot drop in the water <br /> level when pumping 20 gallons-per 'minute) , he noted that the sandstone <br /> permeability (at 230 feet) may be quite low. Therefore, the cone-shaped <br /> depression in the water level would be large; again increasing the <br /> liklihood of effluents seeping into the cone and hence into the well <br /> itself. <br /> Stephenson noted that there are enough "red flags" that the ground <br /> water situation should be closely evaluated before the new area is <br /> developed. For example, is there a divide (peak) in the water table <br /> which follows the contour of the hill? If so, the ground water in the <br /> new area should flow "downhill," away from current wells. <br /> As for new wells, Stephenson suggested that it may be advisable <br /> to case all the way to the 'water level when pumping." It also may be <br /> necessary to drill new wells for current residents, also casing to• <br /> the water level when pumping. <br /> surface <br /> drain field° - 0 1 S - S6 i L 8 feet soil <br /> • <br /> CIfs t .-'c-, 1(o i - - casing to 40 feet <br /> fissured limestone <br /> -1J- <br /> 140 foot <br /> open hole It 5 . s S sandstone/limestone <br /> 2..c. <br /> t <br /> (jQ 4 ' _water table S?,.-�'t �e¢.�..�p= c.,,,--r(- <br /> /( 0 #one �.ssct L <br /> II . f-i- ' , r,..,r ,,,s le.,,,`L water level when pumping <br /> 2 _ � <br /> , 11\N <br /> ii <br />
