The heavy metals with a "t" subscript by their symbol represent total measurements, while <br />the others are dissolved concentrations. The "tr" subscript for iron indicates total recoverable iron. <br />Dissolved and total concentrations are similar for most of the heavy metals, except for iron <br />concentrations in some wells where the total values are significantly greater. <br />Iron concentrations have varied over large ranges near the mine pits and at distant wells but <br />no consistent trends have been observed. Levels of aluminum, barium, boron, phosphate and <br />manganese have also varied over significant ranges but no consistent trends have been observed. <br />Arsenic, cadmium, chromium, copper and lead concentrations have been low with a few exceptions. <br />Molybdenum, nickel and selenium concentrations have stayed low. The recent radium 226 values <br />have been low, except for a value of 5.5 pCi/1 for well GF -6. The variability of laboratory analysis is <br />greater for this parameter and this result should not be given any significance until it is supported by <br />future monitoring. <br />3.6 SPRING AND SEEP WATER QUALITY <br />Table B-2 in Appendix B presents the 2007-2016 water -quality data for the springs and seeps <br />at the Trapper Mine. The locations of the springs and seeps that were monitored in 2016 are shown <br />on Maps 2-1, 2-2 and 2-3. Flow from the springs and seeps are shown on Table B-2, which shows <br />that only the East Pyeatt and East Pyeatt South springs exceeded 5 gpm in its discharge rate in 2016. <br />Water quality from the springs and seeps are similar to the ground -water quality for the site. An <br />increase in TDS concentrations was observed in the East Pyeatt Spring in 2000 with fairly similar <br />values in 2016. East Pyeatt South Spring has similar TDS values to those observed in East Pyeatt <br />Spring. The TDS for Coyote for 2016 was similar to values measured historically for this site. <br />Trapper Mining Company 3-10 <br />2016 Annual Report <br />
