III. MONITORING WELLS <br /> The table below summarizes well designation, top of casing <br /> elevation and aquifer monitored during 1990. <br /> WELL ELEV. AQUIFER LOCATION <br /> FPW 4780 Ennis Draw Mine <br /> DH96 4764 Ennis Draw Downstream from Mine <br /> DH122 4814 Ennis Draw Upstr-am from Mine <br /> SMW-2 4803 Reclaimed Spoil Mine <br /> AMW-1 4804 Undisturbed Mine-Downstream/Ash <br /> Overburden <br /> AMW-2 4811 Reclaimed Spoil Mine-Downstream/Ash <br /> Dry at Bottom of Ash <br /> Elevation <br /> IV. ANALYSIS OF FIELD DATA <br /> A. Water Levels. <br /> Figures 1 through 5 in the Appendix show water levels measured for <br /> years 1986 thru 1990. The 2/3/89 piezometric map has been <br /> included in the Appendix. Water levels were checked in other wells <br /> including DH 133, DII 137, DH 162, DH 172, SMW-1, DH 97 <br /> and DH 116. The only significant change noted was a five foot <br /> rise in water level at SMW-1 . This would increase the water <br /> level in this hole to 4737 elevation, not enough to effect anything <br /> on the map except to bring the 4740 water level elevation contour <br /> closer to SMW-I . <br /> Caps on wellheads were improved after the Federal inspector found a <br /> number of caps rubbed off by grazing cattle. No more open wells <br /> have been found since the upgrading. <br /> B. pH. <br /> Please refer to Figures 6 through 10 in the Appendix which show <br /> field pH values for 1986 thru 1990. <br /> C. Specific Conductance. <br /> Figures 11 thru 15 in the Appendix show conductance field values <br /> collected from 1986 thru 1990. <br /> V. WATER QUALITY ANALYSIS <br /> Laboratory reports regarding the analysis of the water obtained at <br /> the same time as the field testing is in the Appendix following the <br /> field test results. <br /> Page 8 <br />
