• MINE HATER <br />The mine was sealed in 1986. No provisions were made for monitoring the <br />water level once sealed, therefore, no mine inflows information was collected <br />in 1987. The unknown head on the formerly monitored mine inflows prevents <br />protecting water levels. No mine inflows map for 1987 is being submitted. <br />CDNSUNPTIYE USE OF YATER <br />There was no consumptive use of water during the year. <br />HYDRDL06IC IMPACTS <br />The hydrologic impact from the reclaimed mine site is minimal. This fact <br />is even more apparent now that the #1 Pond and associated springs have been <br />eliminated from monitoring results. The total dissolved solids discharged <br />from the #5 Pond in 1981 was equivalent to the total dissolved solids <br />discharged in nine days of mine water discharge in 1985. <br />If the regrading of the top of the mine bench was the cause of the higher <br />water level in piezometer P-1, then the water must have flowed through the <br />alluvial cover on the refuse pile or the alluvial material on the north edge <br />• of the refuse pile. Either case would indicate very low permiability of <br />the refuse compared to the alluvium. The water level in the three wells <br />developed into the refuse zone remained the same or decreased while the water <br />level to P-1 increased. The low permiability of the refuse will reduce the <br />potential for minerals leaching out of the refuse. <br />• <br />-3- <br />
