Ranked by the Purity Score of each city's main water system, highest first. Scores belong to water systems; there is no state score. The score is computed only from contaminants measured in the published EPA record, so this ranks the record, not which city's water is safest. How the score works.

How does Georgia tap water compare across cities?

PurityMap ranks 120 cities in Georgia by the Purity Score of each city's main water system, computed only from contaminants measured in the published EPA record. Scores belong to water systems, not to cities. The highest published score is Gwinnett County's main water system: GWINNETT CO. DEPT. OF WATER RESOURCES · PWSID GA1350004 · Purity Score 100 (Excellent) · Confidence: moderate · Assessed at the water-system level. The ranking compares the records, not which city's water is safest, and your own tap can differ with household plumbing.

How many Georgia cities have PFAS above the federal limit?

30 cities of 120 had at least one regulated PFAS (PFOA, PFOS or PFHxS) measured above the 2024 federal limit in EPA's UCMR 5 testing, including LaFayette (PFOS 56 ng/L), Augusta (PFOS 51 ng/L), Columbus (PFOA 33.9 ng/L). PFAS were detected at any level in 55.

Is there lead in Georgia tap water?

Utilities report lead as a 90th-percentile result from home taps. 81 of 120 Georgia cities reported a value above zero, and none was above the 15 µg/L federal action level. Lead usually comes from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.

Have Georgia water systems had drinking-water violations?

3 cities in Georgia have a health-based violation in the federal SDWIS record within about the last ten years. Each city report lists the contaminant, year and whether it was resolved.

Limits, sources and corrections

A statewide page cannot tell you what reaches a specific address. Water quality varies by supplier, sampling period and household plumbing; open a city report for the evidence behind a local result.

Sources: EPA UCMR 5 (PFAS, 2024), SDWIS Lead and Copper Rule 90th-percentile results and health-based violations, and utility Consumer Confidence Reports where on file. Every city report links its dated source records.
