10, 11, 12 and 13) . <br /> Representative water quality of the inflow was measured. <br /> Table 5 presents the temperature, conductivity and pH of each <br /> source. Quality of those sources seeping from job or abandoned <br /> mine areas was higher in temperature and conductivity than those <br /> areas of current workings. Quality ranged from 135 to 326 umhos/cm <br /> conductivity, 11 to 16 degrees Celsius temperature and 6. 6 to 7 . 5 <br /> S.U. pH. <br /> Mine water inflow was collected in a sump and discharged <br /> from the mine by pumping. Table 3 presents average daily discharge <br /> from the mine (calculated from daily pump records and averaged for <br /> each month) . Figures 3 and 4 graphically display this hydrograph <br /> for 1988 and 1989. Average daily discharge ranged from 106, 300 gpd <br /> during June 1989 to 128,800 gpd during January 1989. The mine <br /> inflow study estimated 78. 5 gpm flowing into the mine which relates <br /> to 113 , 040 gpd. Calculated discharges were somewhat lower than <br /> estimated inflow (Table 3) . <br />
