Management Strategies to Protect Water Resources

Mitigating thee water resource impacts of strip mining requises a combination of incorporaering controls, regulatory compleance, and long-term stewardship. The following strategies are widely incorporan mining operations, specilarly in acquisitions with strong environmental oversight.
