1 <br /> <br />' 2.0 WATER LEVELS <br />' Water levels or water pressure have been mea~;ured in 29 wells at <br />the Trapper Mine. Wells GF1, GF3, and GD2 area flowing wells and <br />pressure readings on these wells has been converted to static water <br />' head above land surface. A few recent water level:a have been measured <br />on well GC2. Well GD1 is not measured for water level because a pump <br />' is installed in this well and well GZ1 is dry. We:Lls GZ1, GZ2 and GZ3 <br />' were destroyed by mining during 1986 as approved by the Colorado Mined <br />Land Reclamation Division. <br />' The location of the monitoring wells is shown on Map No. 2-1. <br />' Wells GD1, GF1, and GZ1 are completed in the Twenty Mile Sandstone, <br />while wells GF2 and GZ2 are completed below the R coal in the U <br />' aquifer system. Five wells, GA1, GE1, GZ3, GD2, and GF6, are used to <br />monitor the QR aquifer. Wells GA2, GB1, and GF3 are used to monitor <br />the KLM aquifer. Four wells, GBS, GC1, GE2, and GF4, are used to <br />observe changes in the HI aquifer. Wells GB2, GC2, GBB1, and PB are <br />used to monitor the Third White Sandstone aquifer. Wells GE3, GBB2, <br />' and PS are completed in the Second White Sandstone between the G and F <br />coals while well P3 is perforated in the Lewis Shale. Five alluvial <br />' wells, GBB3, GC3, P1, J1 and COY are also monitored. Well GF5 is <br />' completed in the backfill aquifer in an area where the HI seams were <br />mined. <br />1 <br />' 2-1 <br />
