The Clean Water Act (CWA) is primarily focused on what aspect of environmental protection?

The Clean Water Act (CWA) is primarily focused on regulating the discharge of pollutants into navigable waters. This act plays a critical role in protecting water resources in the United States by establishing the framework for regulating discharges of various pollutants directly into lakes, rivers, and coastal waters. The CWA aims to maintain and restore the integrity of the nation's waters, ensuring they are safe for recreational activities, wildlife, and ecosystems.

Under the CWA, pollution control programs and standards are implemented to manage water quality, thereby addressing a range of contaminants that may negatively affect water bodies and their surrounding environments. By concentrating on navigable waters, the CWA serves as a vital tool for safeguarding aquatic ecosystems and ensuring public health through clean water access.

The other areas mentioned, such as air quality management, solid waste management, and wildlife habitat preservation, are typically addressed by different environmental laws and regulations, highlighting the specific focus of the Clean Water Act on water quality and pollution control.
