Mining and Water Pollution — Safe Drinking

Mining affects fresh water through heavy use of water in processing ore, and through water pollution from discharged mine effluent and seepage from tailings and waste rock impoundments. Increasingly, human activities such as mining threaten the water sources on which we all depend. Water has been called "mining's most common casualty" (James Lyon, interview, Mineral Policy Center

Mining's Impact on Water Polliution | Business

Mining operations use large amounts of fresh water to process recovered ore; the resulting mine effluent is typically a stew of hazardous acid-generating sulphides, toxic heavy metals, waste rock impoundments and water—and it is often deposited nearby in large free-draining piles where it can pollute land and water supplies for decades to come. When this waste water drains into local streams
