Hello!

The correct answer is A. gave the EPA the authority to regulate water quality in navigable waterways.

The Clean Water Act is a federal law which governs water pollution. Its main objectve is to mantain the integrity of the United States waters; it is administered by state governments and the U.S Environmental Protection Agency (EPA). Navigable waters are protected by the CWA but it does not protect groundwater since groundwater protection is included in the Safe Drinking Water Act.

Hope this helps
