Raton Creek Mine -Energy Fuels Mining Company <br />2002 AHR -Page 2 <br />Well levels for both monitoring wells are presented graphically on Figures 1 and 2 for the <br />Refuse and Iuppa Wells, respectively. A review of water levels data shows steadily declining, <br />levels in the Retuse Well during the reporting period. The lower water levels probably follow <br />from the prevailing drought conditions. The unusually low level at the end of the fourth quarter <br />is, however, under question. This level was monitored by a third party and may be in error. <br />Monitoring results from the following quarter indicated a water level consistent with the <br />historic average. <br />Water levels at the Iuppa Well remained relatively steady azound the 14-feet level, remaining <br />lower than the long-term average. The fluctuations are likely influenced by the landowner's use <br />of the well, and the lower levels may result from the continued low amount of precipitation <br />during recent reporting periods. <br />- - The approved ground- water monitoring program adequately-monitors potential- impacts of I <br />mining on the ground water system~'I'Ite ila~ta collected through the penod of this ~gpo~t ,.~.. - _ <br />- - - indicate tharno sigmfieant ground-wat'er impacts have occurred, as a result of_mming.- '- T---=- _ ~ I <br />Surface Water and NPDES Discharges <br />_,: T-: _ <br />~~. <br />-- _ __ ~-- :- ,- .. - -_w. -sue ~~:-~.: =-~.-- _ <br />Current and historic water quality data collected from the approved monitoring point on the <br />Starkville Diversion are shown on water quality Table 4.
