The deep piezometers: W-lA at about Elevation 6327 (tip elev.l,W-1C at <br />about Elevation 6210 (tip elev.) and W-1F at about Elevation 6198 (tip elev.) <br />near the substation, and reportedly PP-4 and PP-7 further down the slope <br />are essentially dry indicating that either there is no water deep in the <br />formation _ that the deep formations are pervious enough to discharge the <br />water out at a faster rate than the water is flowing is during this time of <br />the year. <br />4. The production well and deep piezometers near the substation: W-1, W-1D, <br />sad W-lE located in the bedrock formation and W-1B located at the <br />bedrock/colluvium interface have a limited amount of water that appears to <br />be assoaated with the coal seams. W-1 was the deep pumping well and the <br />depths of water and responses to the pump test in W-1$, W-1D, and W-lE <br />are as follows: <br />(a) W-1B currently has about 27 feet of water and quickly dropped shout <br />4.8 feet during pumping and after 2 weeks has recovered over <br />3.2 feet. Current elevation of water is about 6262. <br />(b) W-1D currently has about 8 feet of water and is slowly dropping by <br />about 2 feet after 3 weeks since installation (and perhaps since <br />pumping}. Current elevation of water is about 6308. <br />(c) W-lE currently has about 7 feet of water and quickly dropped about <br />4 feet during pumping and after 2 weeks has recovered almost 4 feet. <br />Current elevation of water is about 6262. <br />as2eoi4~wesi.vcE r <br />
