<br />in March 1995 from the Refuse Area ponds and a flow was measured and sampled at Station <br />SW23-1. This sample had a TDS of 656 mgA. <br />' 2.2.2 Ground Water fiAonltorlnq Data Groundwater monitoring data consists of water levels <br />' measurements. Tabulation of the raw data is included in Appendix C. Hydrographs for the 15 <br />stations (monitor holes) from which water level data was collected are included in Appendix D. <br />Table 2-2 is a statistical summary of the water level data. <br />2.2.2.1 Alluvial Water Level Data Water level data has been collected from the one remaining <br />' original alluvial aquifer monitoring hole (QAL-5) and the Refuse Disposal Area alluvial monitoring <br />hole (RM-1). Five other alluvial monitoring holes were inundated by Kenney Reservoir. Ahydro- <br />graph of the water level data for QAL-5 is contained in Appendix E. The statistical summary of the <br />water level data for QAL-5 is also included in Table 2-2. No water has yet been detected in RM-1. <br />The locations of these monitoring holes are shown on Plate 1 in the pocket of this report. The dal-5 <br />hydrograph shows the major increase in the alluvial water level of the White River during the first <br />haH of 1985. This rise was due to the filling of Kenney Reservoir. Since that Ume, fluctuations <br />reflect the rise and fall of the reservoir level. <br />' 2.2.2.2 Alluvial Water Quality Data The water quality data for QAL-5 is contained in Appendix <br />E. The statistical summary of the data is also contained in Appendix E. A statistical summary of <br />depths for QAL-5 is also included in Table 2-2. The fifth annual hydrology report noted that the <br />general increase in the average TDS that started when Kenney Reservoir was filled was beginning <br />to slow down. Based on the data collected during the present water year, the TDS continues to <br />decrease. The TDS ranged from 5280 mgA to 3760 mg/I with an average of 4708. This compares <br />to an average during the previous reporting period of 5637 mgA. A graph showing the magnesium, <br />' chloride and TDS levels for QAL-5 is also incuded in Appendix E. <br />The water quality of the White River is considerably better than that in the alluvium indicating that <br />permeability in the alluvium is restricted resulting in a relativey low degree of communication <br />between the river water and the water in the alluvium. The existence of Kenney Reservoir <br />' decreases the groundwater gradient which may inhibit any natural tendency for the alluvium to flush <br />itself of the higher dissolved solids content. The potential effects, therefore, were projected that the <br />dissolved solids of the White River alluvium in the vicinity of Scullion Gulch would continue to <br />increase to a higher level and stabilize on an average basis. Apparently this more or less stable <br />level was reached and a decreasing trend continues. <br />1 <br />6 <br />
