New Jersey American Water, Penns Grove system: 2025 water quality report results
The New Jersey American Water, Penns Grove system's 2025 water quality report doesn't include regulated PFAS results. Lead at the 90th percentile of home taps: 1 ppb. Hardness: 115 mg/L (moderately hard).
Correction, October 24, 2026. From October 22 to October 24, 2026, the pages for New Jersey American Water's Penns Grove system and the towns it serves (Penns Grove and Carneys Point) showed PFOA at 1.25 ppt and PFOS at 1.05 ppt. Those values are printed in the Penns Grove system's 2025 report, but in the section for the Logan system, which supplies water to it through an interconnection. We removed them. The report gives no PFAS compliance result for the Penns Grove system itself. All corrections.
2025 results against New Jersey and federal limits

The 2025 report doesn't list arsenic, 1,2,3-trichloropropane or chloride. 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.
The 2025 report doesn't include regulated PFAS results.
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's report doesn't include PFAS results, so we can't match a PFAS filter to this water. If you're concerned about lead from your home's pipes, look for a filter certified to NSF/ANSI Standard 53 for lead.

Water sources
Penns Grove System is a public community water system consisting of 6 wells that draw from the Potomac-Raritan-Magothy (PRM) Aquifer. This system may receive additional supply through an interconnection with our Logan System, which consists primarily of PRM groundwater, but may also include treated surface water from the Delaware River.
