Victory: groundwater covered by the Clean Water Act

The U.S. Supreme Court has ruled that polluted water that flows underground into nearby lakes, rivers, and bays is covered by the Clean Water Act. The law prohibits the unpermitted discharge of pollutants into navigable waters or at points where the water also reaches the same result by similar means.
