How does the savannah river impact georgia

The Savannah River supplies drinking water to Augusta and Savannah, Georgia, and Hilton Head, and Beaufort, SC, and many smaller municipalities in the basin. As salt water intrudes into the aquifers near the coast, the freshwater of the Savannah River becomes even more important as a source of drinking water.
