Questions

Frequently asked

How does Salem County tap water compare across cities?

PurityMap ranks 1 city in Salem 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 Pennsville's main water system: PENNSVILLE TWSP. WATER DEPART. · PWSID NJ1708001 · Purity Score 57 (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 Salem 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 Pennsville (PFOA 19 ng/L). PFAS were detected at any level in 1.

Is there lead in Salem County tap water?
