The Clean Water Act impacts mining by requiring the treatment of wastewater to prevent harmful pollutants from contaminating water bodies.

The Clean Water Act (CWA) significantly influences mining operations by mandating the treatment of wastewater before it is discharged into surface waters like rivers, lakes, and streams. This law ensures that pollutants, including heavy metals, sediment, and toxic chemicals, do not harm aquatic ecosystems or public health. Mining activities can generate large amounts of contaminated water, but under the CWA, operators must comply with strict water quality standards. This regulation protects waterways from pollution while promoting responsible mining practices. By focusing on water quality preservation, the CWA plays a crucial role in balancing industrial activities with environmental sustainability.
