Aqua New Jersey, Phillipsburg system: 2025 water quality report results
In its 2025 water quality report, the Aqua New Jersey, Phillipsburg system reported no detections of HFPO-DA, PFBS, PFHxS, PFNA, PFOA and PFOS. Lead at the 90th percentile of home taps: 1.3 ppb. Hardness: 154 mg/L (hard).

The 2025 report doesn't list arsenic or 1,2,3-trichloropropane. New Jersey sets its own limits for arsenic (stricter than the federal one) and 1,2,3-trichloropropane (no federal limit); its sodium and chloride limits are recommended upper limits, not enforceable. Federal limits as of November 2026.
According to EPA, lead gets into drinking water when plumbing that contains lead corrodes, and where a home has a lead service line, that pipe is typically the largest source. So a home's own tap can differ from the system-wide 90th percentile.
EPA kept its 4 ppt limits for PFOA and PFOS. Utilities must meet them by 2029; EPA has proposed letting systems request until 2031. In May 2026, EPA proposed withdrawing its national limits for PFNA, PFHxS, GenX (HFPO-DA) and a combined limit for PFAS mixtures. The proposal isn't final yet; EPA plans to decide in 2026. New Jersey's own PFNA limit is unaffected. (Status as of November 2026.)

Choosing a water filter
The utility didn't detect the PFAS it tested for. If you're concerned about lead from your home's pipes, look for a filter certified to NSF/ANSI Standard 53 for lead.
