Frequently asked

How does Etowah County tap water compare across cities?

PurityMap ranks 1 city in Etowah 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 Boaz's main water system: BOAZ WATER & SEWER BOARD · PWSID AL0000936 · Purity Score 56 (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 Etowah 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 Boaz (PFOA 10 ng/L). PFAS were detected at any level in 1.

Is there lead in Etowah County tap water?
