The Great Lakes
The Great Lakes form the largest surface freshwater system on Earth. More than 30 million people live in the Great Lakes basin, and the impact of their daily activities, from the water consumed to the waste returned, directly affects the Great Lakes environment. EPA leads U.S. efforts to restore and maintain the quality and ecosystems of the Great Lakes watershed.
