changed much during the extended leaching period. There was not much change in sulfate concentration in <br />the leachate over time. <br />Geochemical Data for Individual Sites <br />In figures 4-16, plots are presented for selected leachate geochemical data for each site. Each <br />figure has three plots comparing leachate geochemistry for both the 5-minute and 18-hour leaches. Data <br />presented includes: A, selected major elements; B, selected trace metals; and C, pH, and specific <br />conductance. The plots provide a visual depiction of the data so that geochemical trends are more easily <br />seen. <br />Figure 4.

These <br />rankings were established after compiling and analyzing the leachate geochemical data. This simple <br />ranking scheme was devised in order to rank each mine-waste relative to one another, for their potential to <br />release acid, certain metals, and other constituents into the environment should runoff occur from the mine- <br />Hageman_SIR_2508.doc 8 7/21/20042:50 PM
