New report shows treatment costs as much as $67 billion/year, with new mines polluting and costing billions more

 A new report released today shows existing U.S. hardrock mines (e.g. gold, copper, uranium) will pollute up to 27 billion gallons of fresh water per year, and cost as much as $67 billion per year to clean, in perpetuity. Based on government data, the report also reveals that four proposed mines could annually pollute an additional 16 billion gallons.
