Minimums also occurred at GW -N37 for laboratory conductivity, <br />TDSA, sulfate,'calcium, and magnesium. As shown on the graphs for indicator parameters, also <br />three wells are trending downward for all indicator parameters. All three of these wells are not <br />influenced by the mining and express the up gradient condition. <br />111 Page <br />
