What does the Clean Water Act aim to protect?

The Clean Water Act aims to protect the integrity of the nation's waters by regulating pollutant discharges into navigable waters. This encompasses both natural waters, such as rivers, lakes, and wetlands, as well as drinking water sources that are vital for public health and environmental sustainability. The legislation focuses on maintaining and restoring the quality of water to ensure safe and clean water for all uses, including recreation, fishing, and drinking.

In contrast, the other options do not align with the specific objectives of the Clean Water Act. Air quality pertains to separate legislation focused on air pollution control, while industrial waste is often regulated through different frameworks that may intersect with water regulations but are not the main focus of the Clean Water Act. Land use practices are typically governed by zoning and land use laws rather than direct water quality regulations. Overall, the primary mission of the Clean Water Act is clearly oriented towards safeguarding water resources.
