Showing 1 of 1 cities · scores are system-level, not tap tests

Ranked by the Purity Score of each city's main water system, highest first. Scores belong to water systems; there is no county 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.

Questions

Frequently asked

How does Lamar County tap water compare across cities?

PurityMap ranks 1 city in Lamar County 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 Barnesville's main water system: BARNESVILLE · PWSID GA1710000 · Purity Score 74 (Fair) · 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 Lamar County cities had a PFAS sample above a 2024 EPA limit?

1 of 1 Lamar County city report had a PFAS sample above a 2024 EPA limit in EPA's UCMR 5 testing, including Barnesville (PFOS 4.5 ng/L). That limit is judged on a yearly average, and water systems have until 2029 to meet it, so a single sample is not a violation. PFAS were detected at any level in 1.

Is there lead in Lamar County tap water?

Utilities report lead as a 90th-percentile result from home taps. 1 of 1 Lamar County 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.
