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 Upstream 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, DH 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-l. 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-1. <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 30 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 />• <br />Page 8 <br />
