Saginaw Aquifer

The Saginaw Aquifer is a bedrock aquifer located in central Michigan in the United States. It is part of an aquifer system found in Mississippian or younger stratigraphic units in the Michigan Basin.[1] The aquifer covers approximately 11,000 square miles (28,000 km2)[2] and is estimated to contain 4 cubic miles (17 km3) of water, approximately 50 feet (15 m) to 400 feet (120 m) underground.[3]

The aquifer contains both fresh water and salt water. In areas of the aquifer where fresh water is present, it is a primary source of municipal water, including in Clinton, Ingham and Eaton counties, encompassing the Lansing-East Lansing Metropolitan Area.[4] Only about 0.03 percent of the aquifer is used for drinking, while the rest is for domestic and industrial use.[5]
