The water level in the old Apex II1 mine, which has been <br />abandoned for several years, has stabilized at about the 7355' <br />structural contour on the lower Pinnacle seam. <br />All future mining operations covered by this permit appli- <br />cation will be conducted at absolute elevations above 7300'. <br />A water sample was taken from the sump of the Apex lit <br />Mine on 28 August 1978, and analyzed by the Southeastern Colo- <br />rado Agricultural Laboratories. The results are as follows: <br />Alkalinity 476.01 ppm <br />Total solids 886.0 PPm <br />Vol. mat. (org.) 146.0 ppm <br />Organic matter light <br />Pg 7.8 PPm <br />Hardness 240.0 ppm <br />Sodium 231.1 ppm <br />Calcium 128.5 ppm <br />Hagnesium 111.5 ppm <br />Iron 0,1 PPm <br />Nitrates 0.0 PPm <br />Chlorides 10.6 pPm <br />Sulfates 237.0 PPm <br />Carbonates 0.0 PPm <br />Sulfides 0.0 PPm <br />Flourides 0.2 ppm <br />Arsenic 0.0 PPm <br />Copper 0.0 PPm <br />• <br />J <br />Rev: 4-22-81 <br />s9 <br />
