New Jersey American Water, Harrison system: 2025 water quality report results
In its 2025 water quality report, the New Jersey American Water, Harrison system reported PFOA at 2.5 ppt and PFOS at 2.45 ppt (highest compliance result). PFOA and PFOS are below both the New Jersey and federal limits. Lead at the 90th percentile of home taps: 1 ppb. Hardness: 140 mg/L (hard).
2025 results against New Jersey and federal limits
Highest compliance result in the 2025 report; range in the report: not detected to 4.3 ppt
Below both limits
Highest compliance result in the 2025 report; range in the report: not detected to 3.9 ppt
Below both limits
Each bar shows the highest compliance result reported for this system, in parts per trillion (ppt), against both limits. The darker band is the range of results the report lists; the status compares the reported value, not the top of the range, with the limits.

The report doesn't say whether that figure is a single result or a running annual average.
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.
These values cover part of the supply. These PFAS results come from the Delaware River Regional Water Treatment Plant section of the report. They describe the surface-water share of this system's supply only; the report gives no PFAS compliance result for the system's wells.
The same report also lists EPA's nationwide PFAS testing (UCMR 5), sampled at the point of entry in 2025: PFOA at 4.3 ppt and PFOS at 4.4 ppt. Those are separate test results, not the compliance figures the limits are judged on, so they aren't in the status column.
Other PFAS detected in EPA's nationwide testing (UCMR 5), not charted because the figure isn't a compliance result: PFBS, PFHxA, PFHxS and PFPeA.
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 PFAS compliance results were below the federal limits. If you still want a filter, or you're concerned about lead from your home's pipes, look for one certified to NSF/ANSI Standard 53 for the contaminant you care about.
