Cities ranked by the records

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.

Frequently asked

How does Hancock County tap water compare across cities?

PurityMap ranks 1 city in Hancock 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 Weirton's main water system: WEIRTON AREA WATER BOARD · PWSID WV3300516 · Purity Score 50 (Poor) · 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 Hancock County cities have PFAS above the federal limit?

1 city of 1 had at least one regulated PFAS (PFOA, PFOS or PFHxS) measured above the 2024 federal limit in EPA's UCMR 5 testing, including Weirton (PFOS 8.2 ng/L). PFAS were detected at any level in 1.

Is there lead in Hancock County tap water?

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