Climax is saying it cost to much to treat the water. Cuts into there profits. What is there answer? Put the cost of clean up on the tax payers if they want something as silly as clean water. 
Note what The EPA says, "However, EPA regional officials said in the document filed Friday that they would not object if Colorado’s commission “chooses to be more conservative and adopts a more stringent table value standard of 9,000 ug/L (ppb) as proposed by Climax Molybdenum Company.”  Well bless there heart, this EPA thinks the mine is doing you a favor.
