~. <br />Your notes asked whether further sampling would be necessary at Ute Ule. I <br />would have to look into the file to see what goes, but based on my last look, the <br />Henson Creek water quality was good and showed no signs of contamination <br />from the Ute Ule property. Provided the Division has been provided 5 quarters of <br />baseline water quality results, I would conclude that sampling there could cease <br />unless and until the mill re-activates under this permit. <br />On a related item, sampling at the Golden Wonder is another story. Your note <br />questioned whether continued sampling was necessary at the Golden Wonder <br />mine. Indeed, monitoring is required under DMG's groundwater authority at the <br />Golden Wonder mine and it should continue as long as the mine is active. <br />That we have not received any year 2000 sampling results is somewhat <br />disturbing. The purpose of monitoring at Golden Wonder is to assure that <br />groundwater is not being contaminated over and above the ambient condition. I <br />would say frankly, looking over the analytical results table that you sent, that the <br />huge range of values for metals and pH makes prescribing the ambient condition <br />a considerable challenge. When pH rests in the 2 to 3 range, as it apparently <br />does in most of the near-mine samples at the Golden Wonder mine, dissolved <br />metals concentrations typically show extreme fluctuations. Moreover, it would be <br />difficult to detect metal concentrations any higher than the existing data show <br />because some of the metals are near their saturation limits. <br />Thus, I would conclude that monitoring should continue at the site. While it is <br />feasible that monitoring could be limited to a lesser number of stations, given the <br />extreme variation in water quality results we currently have I would recommend <br />adding to the existing data to better define the ambient condition. <br />cc: Bruce Humphries <br />Tom Gillis <br />Attachment <br />
