2.0 GROUND -WATER LEVELS <br />Water level or water pressure has been measured in 24 wells at Trapper Mine in 2013. <br />Wells GD -2, GF4, GP -3 and GP-4 were flowing wells in 2013 and pressure readings on these wells <br />have been converted to static water head in feet above the measuring point. The water levels are <br />prefixed by a negative sign to indicate a water level above the land surface. Wells GA -1 and GA -2 <br />were destroyed by mining in 1996 (see Hydro - Engineering, L.L.C., 1997 for where these two wells <br />were located) and well GP -1 was destroyed by mining in 2003 (see Hydro-Engineering, LLC 2003). <br />Monitoring of wells GB -1, GB -2, GB -5, GF -1, GF -2 and GF -3 ceased at the end of 2003. Wells 81- <br />03A, GE -1, GE -2, GE -3, GLUX -1 and GP -6 ceased monitoring in mid -2006 after their removal from <br />monitoring. <br />The locations of the monitoring wells are shown on enclosed Maps No. 2 -1 through 2 -3. <br />Well GD -1(2) is completed in the Twenty Mile Sandstone. Three wells, GD -2, GF-6 and GP -5 are <br />used to monitor the QR aquifer. Wells GD -3 and GF -11 are completed in backfill derived from the <br />QR aquifer and, therefore, are also used to monitor the QR aquifer. Wells GP -2, GP-4, and GP -8 are <br />used to monitor the KLM aquifer. Five wells, GC -1, GF-4, GP -3, GP -7, and GMP -1 are used to <br />observe changes in the Hl aquifer. Wells GF -5 and GF -7 are completed in backfill material derived <br />from the HI aquifer and are also used to monitor the HI aquifer. Wells GC -2, P -8, and GP -9 are used <br />to monitor the 3rd White Sandstone aquifer. Well P -5 is completed in the 2nd White Sandstone <br />between the G and F coals. Well P -3 is perforated in the Lewis Shale. Four alluvial wells, COY, <br />GC -3, P -1 and J -1, are used to monitor the Flume, Pyeatt, and Johnson alluviums. <br />Trapper Mining Company 2 -1 <br />2013 Annual Report <br />
