plot of pH is provided in Figures 58AB, 58AC and 58AD for these wells. One trend apparent in the plots is an
increase in the conductivity levels in well AVF -3. Review of water chemistry data indicates that this increase in
conductivity is primarily due to increases in the concentrations of calcium, chloride and sulfate. The source of this
increase in major ions in well AVF -3 is not known. However, it is unlikely due to mine discharge because its location
and the dissimilar chemical composition of mine discharge.
