Banta. <br />Division Director <br />RE: Water Monitoring Plan portion of 1990 Annual Reclamation Plan <br />Colowyo Mine, Permit No. C-81-019 <br />Dear Mr. Kiger: <br />The Division has reviewed the Water Monitoring Plan portion of the <br />1990 Annual Reclamation Report and generally find it to be <br />acceptable. <br />We are concerned that analysis of trends in water quality is <br />hampered by changes in well locations and by the fact that various <br />water constituents have not been analyzed consistently over the <br />years. Specifically, on the tables provided, could you give the <br />reasons for gaps found in the data. For instance, in some cases <br />field parameters were measured while no flow was noted. In other <br />cases, no measurements were apparently taken. A full suite of <br />water monitoring measurements are required according to the terms <br />of both the Division and Colorado Health Department permits. <br />In the future, should beavers dam a stream at an existing <br />monitoring site, Colowyo might consider sampling above the area of <br />ponded water, after obtaining Division approval for a change in the <br />monitoring plan. <br />The Gossard Well No. 1 continues to display high levels of iron. <br />Colowyo might consider procedures to insure accuracy in sampling <br />and, if it appears that sampling is accurate, to try and explain <br />the high iron levels found in Gossard Well No. 1. <br />If you have any questions, please contact either myself or Larry <br />Routten. <br />Sincerely, <br />Stephen F. Wathen <br />Reclamation Specialist <br />
