Why does water hardness vary across Georgia?

Water hardness varies across Georgia because utilities can use different groundwater wells, reservoirs, treatment plants, blends, and distribution zones. Private wells can also differ from nearby municipal water.

What city in Georgia has the hardest water?

Brunswick has the hardest water among higher-confidence Georgia city pages at 238 PPM. Check the city page for local systems and ZIP codes before making treatment decisions.

Does this include municipal water, well water, or both?

The state report combines public water system records, utility reports, and USGS monitoring where available. Municipal treated-water records are preferred when present. Private well hardness can vary at the address level and should be confirmed with a local test.

How many water systems are in Georgia?

Georgia has 1,739 active community water systems serving 539 cities.
