<br />-lo- <br />Water in Oak Creek is of a poorer quality than that of Trout Creek, Oak Creek <br />is not within the active mine area and as predicted, has not shown any mine <br />related degradation of water quality. Substantial disturbance along Oak <br />Creek, including several abandoned underground mines which drain water <br />directly into Oak Creek, and the lower flows of this drainage cause the poorer <br />water quality. <br />Alluvial water quality along the Trout Creek is variable and dependent on the <br />system's interconnection with the surface water system. Some wells monitored <br />(TR1 and TR2) exhibit poor water quality similar to that of the spoils water <br />tested. Other wells (TR1.5, TR3 and TR4) show water quality similar that of <br />the downstream surface water site on Trout Creek. TRI, located adjacent to <br />active mining, has shown an increase in many chemical parameters indicating <br />that present mining is having some effect on the alluvial waters in this area, <br />however, it does not appear that this is not being transmitted to the surface <br />water system or other adjacent alluvial wells. <br />Mining in the Moffat area, a previously undisturbed area, will begin within <br />this term of permit. This area is of particular concern because it is <br />undisturbed and while mining is not predicted to have a significant impact on <br />water quality, these predictions have yet to be substantiated. This area <br />needs to be closely watched by P8d~1 in order to facilitate their permit renewal <br />request for the next term of permit through predictions made based upon actual <br />data collected. <br />/th <br />Doc.
