Is Hoboken, NJ Tap Water Safe to Drink?
Hoboken tap water is legally compliant, but one contaminant exceeds health guidelines. Specifically: PFAS above EPA limits (PFOA: 6.7 ppt, PFOS: 4.6 ppt — limit is 4 ppt each). A point-of-use filter is recommended for drinking and cooking water.

How Hoboken Compares
Hoboken's water is 56% softer than the national average of 138 PPM - ranking in the bottom 66% for hardness nationwide. Most homes here do not need a softener. Within New Jersey, Hoboken has the 3rd hardest water out of 22 cities - 36% above the state average of 45 PPM. Among cities (50k-100k), Hoboken ranks #188 of 258 for hardness.
What Hoboken's Water Means for Your Home
Hardness: 61 PPM - Low Concern
Hoboken's water is moderately hard at 61 PPM. You'll see some spotting on glassware and a film on shower doors over time, but it's not the kind of hardness that demands a full softener. A salt-free conditioner is worth considering if you have a tankless water heater or high-end fixtures.
Contaminants & Safety
Forever chemicals (PFAS) are worth watching here. Hoboken has PFOA at 6.7 ppt and PFOS at 4.6 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
Hoboken's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 45 ppb (56% of the legal limit, but 300x 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 0.0633 ppb, which is 3.2x 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.
| Contaminant | Detected | Health Guideline | Legal Limit | Status |
|---|---|---|---|---|
| Hardness (as CaCO₃) | 61 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 98 PPM | < 300 PPM | 500 PPM | ✓ OK |
| PFAS (total) | 11.3 ppt | — | No total limit | Detected |
| ↳ PFOA | 6.7 ppt | 0 ppt | 4 ppt (2024) | ⚠ Exceeds |
| ↳ PFOS | 4.6 ppt | 0 ppt | 4 ppt (2024) | ⚠ Exceeds |
| Lead | 2.2 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ✓ Low |
| Chlorine / Chloramine | 1.2 mg/L | Taste threshold ~1.0 | 4.0 mg/L | ✓ Normal |
| Nitrate | 0.338 mg/L | 5 mg/L | 10 mg/L | ✓ OK |
Recommendations for Hoboken Homes
Recommended Filter for Hoboken
PFAS exceed EPA limits (PFOA: 6.7 ppt, PFOS: 4.6 ppt — limit: 4 ppt each). A certified filter reduces these contaminants effectively.
Quick Fix for Chlorine: Shower Filter
At 1.2 mg/L chlorine, many Hoboken residents notice dry skin, brittle hair, and that "pool smell" in the shower. A shower filter installs in 5 minutes, no tools needed.

About Hoboken's Water Supply
Water Utility: Suez Water NJ
Water Source: Passaic River, Hackensack River (Surface Water)
Population Served: 52,000
Hardness: 61 PPM (3.6 grains per gallon)
Hoboken's drinking water comes from surface sources — Passaic River, Hackensack River. 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 52,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Suez Water NJ's Consumer Confidence Report (CCR) or test your own tap.
