the undisturbed eastern portion of the permit area generally showed <br />elevated concentrations of NHa and NOs in 1992, is indicative that •' <br />the observed changes in these constituents are a natural variation <br />and not related to mine activities. <br />3.6 OTHBE CONSTITDSNTS <br />The major constituents other than the carbonates are presented <br />on pages B-80 through B-99. The heavy metals with a "t" subscript <br />by their symbol represent total measurements, while the others are <br />dissolved concentrations. Dissolved and total concentrations are <br />similar for most of the heavy metals, except for iron <br />concentrations in some wells where the total values are <br />significantly greater in some wells. <br /> <br /> <br />3-14 <br />
