Will give a brainlest the clean water act does not ensure high water quality throughout the nation because it does not address interstate navigation apply to all states address drinking water have a means of enforcement

have a means of enforcement

Explanation:

The Clean Water Act is an American law whose primary purpose is to preserve the physical and chemical integrity of water by monitoring the discharge of polluting products. Since its inception, the primary concern of this standard has been in large point sources of pollutant discharge, such as industries and sewage treatment plants. These were the most obvious sources of pollution, easily identifiable and most easily controllable.

As you can see this law has a means of enforcement, which is to promote the integrity of water bodies that receive pollutants. As it is not a comprehensive law, it does not guarantee high water quality throughout the country.
