The 1974 congressional safe drinking water act -empowered congress to protect groundwater in the us -empowered the epa to protect groundwater in the us -gave congress the authority to regulate water quality in navigable waterways -gave the epa the authority to regulate water quality in navigable waterways

The correct alternative is -empowered the EPA to protect groundwater in the US.

The original Safe Drinking Water Act (SDWA), passed in 1974 by Congress meant to address public health by regulating public drinking water supplies. This law addresses all waters designed for drinking, being those above ground or underground sources. The Act authorizes the EPA to establish minimum standards for tap water and demands public water systems to comply with these standards. Even though the original act was target of a lot of controversy and inefficiency, posterior amendments and adaptations led to a successful application of the act and an increase on the quality and safety of water in the U.S.

The correct answer on Edgen is:

(B.) empowered the EPA to protect groundwater in the United States.

I just took the test and this is the right answer.
