<br />were inundated by Kenney Reservoir. A hydrograph of the water level data for QP,L-5 is <br />contained in Appendix E. The statistical summary of the water level data for QAL-5 is also <br />' included in Table 2-2. The location of QAL-5 is shown on Plate 1 in the pocket of this report. <br />The Qal-5 hydrograph shows a significant increase in the alluvial water level of the White River <br />since the second half of 1985. This rise was due to the filling of Kenney Reservoir. Since that <br />time, Fluctuations reflect the seasonal rise and fall of the reservoir level. <br />' awl ~C~~,~ <br />2.2.1.2 Alluvial Water Quality Data The water quality data for QAL-5 is contained in <br />Appendix E. The statistical summary of the data is also contained in Appendix E. A statistical <br />' summary of depths for QAL-5 is also included in Table 2-2. The fifth annual hydrology report <br />noted that the general increase in the average TDS that started when Kenney Reservoir was <br />filled was beginning to slow down. Based on the data collected during the present water year, <br />t the TDS value is 3170 mg/I. This compares to an average during the previous reporting period <br />of 3875 mg/I. A graph showing the magnesium, chloride and TDS levels for QAL-5 is also <br />' included in Appendix E. <br />The water quality of the White River is considerably better than that in the alluvium indicating <br />that permeability in the alluvium is restricted resulting in a relatively low degree of <br />communication between the river water and the water in the alluvium. The existence of Kenney <br />1 Reservoir decreases the groundwater gradient which may inhibit any natural tendency for the <br />alluvium to flush itself of the higher dissolved solids content. The potential effects, therefore, <br />were projected that the dissolved solids of the White River alluvium in the vicinity of Scullion <br />' Gulch would continue to increase to a higher level and stabilize on an average basis. There is a <br />18% decrease in the TDS during this water year compared to the previous year (average 3170 <br />' mg/I vs. 3875 mg/I). <br />2.2.1.3 Bedrock Water Level Data Hydrographs for the 16 bedrock monitoring holes are <br />' contained in Appendix D. Table 2-2 contains a statistical summary of the water level data <br />from the monitoring holes. The locations of the holes are shown on Plate 1 in the pocket of <br />' this report. As noted in the original Deserado Mine permit application, the three zones being <br />monitored (upper sandstone facies, siltstone and coal facies, and the lower sandstone) <br />identify three different stratigraphic zones which lack the characteristics of typical aquifers. <br />' The strata are tight as demonstrated by pumping tests. <br />' The "upper sandstone facies" hydrographs, designated by the hole name ending in "U" are <br />water level depths in feet over time. <br />' Monitor hole 2-17U, located immediately over the East Mains, was mined under during <br />November of 1985. There was an insignificant drop of 0.1 foot in the water level from the <br />5 <br />
