Is Harrison Township tap water safe?
We don't say whether Harrison Township's tap water is safe to drink: that's a health question, for your doctor or your utility. What we show is what the utility reported next to New Jersey's and EPA's legal limits, starting with PFAS here; hardness and lead follow below.
For PFAS, the Harrison system's 2025 water quality report lists the highest compliance result: 2.5 ppt of PFOA and 2.45 ppt of PFOS. The report doesn't say whether that figure is a single result or a running annual average. These were below both New Jersey's limits (14 ppt for PFOA and 13 ppt for PFOS) and EPA's national limits (4 ppt each). These values cover only part of the supply; the Harrison system page explains which part. The statewide PFAS table puts these figures next to the other water systems on this site.
