Hinesville Water Hardness & Quality Report (2026)

Hinesville, Georgia, the Liberty County seat — a major southeast Georgia military city (Hinesville is the Liberty County seat and the primary community adjacent to Fort Stewart — one of the largest US Army installations in the eastern United States and the home of the 3rd Infantry Division, a major Army combat division; Hinesville's economy and community are almost entirely shaped by Fort Stewart), a diverse Liberty County community with a significant active-duty military, African-American, and Hispanic-American population, a community with a very young and transient population (military installation communities have high turnover rates typical of all US Army post communities), and one of the fastest-growing military communities in the southeastern US — draws its municipal water supply from the Upper Floridan Aquifer via the City of Hinesville Water Division. Water hardness in Hinesville measures 96 mg/L — classified as moderately hard.

Hinesville's moderate hardness reflects the southeast Georgia Coastal Plain's Upper Floridan Aquifer calcareous character. The Upper Floridan Aquifer at Hinesville–Liberty County draws from the Eocene Ocala Limestone and Oligocene Suwannee Limestone (calcareous-moderate marine carbonate of the southeast Georgia–Florida Coastal Plain). City of Hinesville treatment produces the moderate 96 mg/L.

With hardness at 96 mg/L, Hinesville residents encounter moderate scale accumulation. Monthly cleaning is recommended. City of Hinesville Water Division consistently delivers water meeting all Georgia EPD and EPA Safe Drinking Water Act requirements.
