Questions

Frequently asked

How does Marion County tap water compare across cities?

PurityMap ranks 1 city in Marion 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 Ocala's main water system: OCALA, CITY OF (2 WTPS) · PWSID FL3420922 · 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 Marion 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 Ocala (PFOS 39 ng/L). PFAS were detected at any level in 1.

Is there lead in Marion County tap water?

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