The latest request for a new drinking water reservoir in Georgia isn't coming from Metro Atlanta, but from the coast. Savannah officials say, the city is going to need a new drinking water source when the Savannah harbor is deepened. The deepening project will push saltier water into the Savannah River, where the city gets much of its drinking water.
U-S Army Corp of Engineers officials are proposing treating Savannah drinking water with lime to offset potential effects of harbor deepening. The lime would prevent corrosion from saltier water the city expects to pump out of the Savannah River after the deepening. But using lime could have its own effects.
