The primary purpose of the Clean Water Act for mining is to prevent pollutants from entering waterways and affecting water quality.

Established in 1972, the Clean Water Act (CWA) is essential for safeguarding American rivers against pollution, especially those caused by mining operations. To enhance water quality and stop dangerous materials from contaminating rivers, lakes, and streams, it establishes guidelines for the discharge of pollutants into navigable waters. The CWA protects aquatic life and public health by ensuring that waste runoff from mining, including chemicals and metals, does not end up in water bodies. To lessen the negative environmental effects of mining on water resources and to encourage sustainable water management techniques, the law mandates that mining enterprises manage water outputs appropriately.
