~~• E1IPIRE ENERGY CORPORATION No. 5 dine Sump Water Qua ity III IIIIIIIIIIIII III As stipulated in the permit for Empire Energy's Eagle No. 5 and Cdo. 9 Clines, an analysis of the water pumped from the new sump in the No. 5 Clines was to be performed. This report summarizes the results of the testing and includes a comparison of this water (which was in the sump up to 54 days) to fresh mine inflow water, a copy of the results (Tables 1 and 2), and Stiff diagrams (Tables 3 and 4). The sump water and the fresh water inflow water are of approximately the same water quality. They are both strongly sodium-bicarbonate waters. The sump water has slightly higher sulphate and lower alkalinity and sodium levels. The dissolved solids values are similar with the fresh ~(~, I~ mine inflow having a higher value. There is no significant -di-fference in ~4 °~ the pH values. The metals are very close; many of the trace metals are ~~ ,~ below the detection limit in the sump sample; 1.30 mg/L in the sumyversus~ ~'',~", ~ 0.40 in the fresh water for total and 0.29 mg/L in the sump and X0.02 mg/L r 1,, a in the fresh water for dissolved. ~~,~~h` ~ The comparison indicates that both waters would be suitable for agricultural use and that there is no significant deterioration in water ~ quality with residence time in the sump. In fact, the sump water appears to be slightly better in quality. This might be explained by the alkaline pH which provides a favorable environment for the precipitation of petals as well as for their adsorption by the wall rock.
