Cities ranked by the records

Showing 6 of 7 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 Ocean County tap water compare across cities?

PurityMap ranks 7 cities in Ocean 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 Lavallette's main water system: LAVALLETTE WATER DEPT · PWSID NJ1515001 · Purity Score 99 (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 Ocean County cities had a PFAS sample above a 2024 EPA limit?

3 of 7 Ocean County city reports had a PFAS sample above a 2024 EPA limit in EPA's UCMR 5 testing, including Toms River (PFOA 9.8 ng/L), Lakewood (PFOA 7.5 ng/L), Point Pleasant Beach (PFOA 7.3 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 3.

Is there lead in Ocean County tap water?

Utilities report lead as a 90th-percentile result from home taps. 7 of 7 Ocean 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.
