PtichkaEL [24]

Answer: Option C) "excludes agricultural runoff"

Explanation:

The Clean Water Act (CWA) established in 1972 is a federal law made in United States to address the adverse effect of water pollution. The act was aimed to maintain the physical, chemical, and biological integrity of the nation's waters.

The federal CWA establish water quality standards and total  maximum daily loads (TMDLs) to asses the pollution caused by agricultural water with the help of regulatory mechanisms.

Hence, the correct option C.
