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 Atlantic County tap water compare across cities?

PurityMap ranks 7 cities in Atlantic 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 Margate City's main water system: MARGATE CITY WATER DEPARTMENT · PWSID NJ0116001 · Purity Score 98 (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 Atlantic County cities had a PFAS sample above a 2024 EPA limit?

2 of 7 Atlantic County city reports had a PFAS sample above a 2024 EPA limit in EPA's UCMR 5 testing, including Pleasantville (PFOA 10.9 ng/L), Atlantic City (PFOA 4.7 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 Atlantic County tap water?

Utilities report lead as a 90th-percentile result from home taps. 6 of 7 Atlantic 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.
