Is Jersey City, NJ Tap Water Safe to Drink?
Jersey City tap water is legally compliant, but one contaminant exceeds health guidelines. Specifically: PFAS above EPA limits (PFOA: 7.9 ppt, PFOS: 6.87 ppt — limit is 4 ppt each). A point-of-use filter is recommended for drinking and cooking water.

How Jersey City Compares
Jersey City's water is 72% softer than the national average of 138 PPM - ranking in the bottom 76% for hardness nationwide. Most homes here do not need a softener. Within New Jersey, it ranks #15 of 22 cities (13% below the state average of 45 PPM). Among large cities (200k-500k), Jersey City ranks #129 of 165 for hardness.
What Jersey City's Water Means for Your Home
Hardness: 39 PPM - Low Concern
Jersey City's water is slightly hard at 39 PPM. Most households won't notice any issues at this level. Scale buildup is minimal, and a water softener would be overkill. Jersey City is softer than 76% of US cities. If you're thinking about water treatment, contaminant filtration is where to focus your money, not softening.
Contaminants & Safety
Forever chemicals (PFAS) are worth watching here. Jersey City has PFOA at 7.9 ppt and PFOS at 6.87 ppt, exceeding the EPA's 2024 limit of 4 ppt per compound. PFAS are synthetic compounds that accumulate in your body over time. A certified carbon filter or reverse osmosis system with NSF P473 certification is the most effective protection. See the regulatory timeline.
What's in the Treatment Process
Jersey City's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 48.2 ppb (60% of the legal limit, but 321x the EWG guideline) and HAA5 at 29.5 ppb (49% of the legal limit, but 295x the EWG guideline). These are within legal limits, but the EWG sets much tighter thresholds based on cancer-risk research. A whole-house activated carbon filter reduces both chlorine and byproducts.
Chromium-6 was detected at 0.0468 ppb, which is 2.3x the EWG health guideline. There's no separate federal limit for chromium-6, only total chromium. A reverse osmosis system is the most effective removal method. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.

About Jersey City's Water Supply
Water Utility: SUEZ
Water Source: Boonton Reservoir (Surface Water)
Population Served: 262,000
Hardness: 39 PPM (2.3 grains per gallon)
Jersey City's drinking water comes from surface sources — Boonton Reservoir. Surface water requires more extensive treatment than groundwater, including coagulation, filtration, and disinfection. This heavier chlorination is why disinfection byproducts tend to be higher in surface-supplied systems. On the upside, surface sources often deliver softer water than deep aquifers. The system serves 262,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request SUEZ's Consumer Confidence Report (CCR) or test your own tap.
