Lothhead <br />E.ecutrve Direcrnr <br />Hal D. Simpson <br />Division of Minerals B Geobgy Stale Engineer <br />Steven J. Wine. P.E. <br />Division Engineer <br />I am responding to your letter to me concerning the Agile Stone project near <br />Parkdale and your concern that potential blasting of stone by Agile Stone may <br />cause turbidity problems in your well. <br />Depending on the magnitude of the blasting, and it's proximity to your well, <br />it may be possible that the blasting could cause some temporary discoloration <br />in the your well water. However, I do not believe that this situation would <br />exist very long or have any adverse health effects. Turbidity is also fairly <br />easy to filter out should any occur. <br />Impacts on well production is very difficult to predict. One of the best <br />ways to determine any changes in water quality or well production is to have <br />a monitoring program. Ideally, you should have as much data as possible <br />prior to any mining activity. If no information has been gathered on water <br />quality and well production yet (water levels, pumping rates, water quality, <br />etc.) you should begin gathering this information as soon as possible. This <br />information ideally needs to be obtained for as many of the existing wells in <br />the area as possible. Testing wells before, during, and after blasting is <br />the best way to be able to detect changes to the groundwater and to prove <br />damages legally. <br />As a referral agency for the Division of Minerals and Geology I am however <br />for.:ar'ing year letter tc ahem and to our main office in Denver. <br />Sincerely, <br />Steven J. attne <br />Assistant Division Engineer <br />c-re-rr ~F <br />999 <br />COLORADO <br />Cc: Dick Wolfe <br />Division of Mining and Geology <br />
