Is Paterson, NJ Tap Water Safe to Drink?
Paterson tap water is legally compliant, but one contaminant exceeds health guidelines. Specifically: PFAS above EPA limits (PFOA: 9.88 ppt, PFOS: 6.9 ppt — limit is 4 ppt each). A point-of-use filter is recommended for drinking and cooking water.

How Paterson Compares
Paterson's water is 70% softer than the national average of 138 PPM - ranking in the bottom 75% for hardness nationwide. Most homes here do not need a softener. Within New Jersey, it ranks #14 of 22 cities (9% below the state average of 45 PPM). Among large cities (200k-500k), Paterson ranks #128 of 165 for hardness.
What Paterson's Water Means for Your Home
Hardness: 41 PPM - Low Concern
Paterson's water is slightly hard at 41 PPM. Most households won't notice any issues at this level. Scale buildup is minimal, and a water softener would be overkill. 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. Paterson has PFOA at 9.88 ppt and PFOS at 6.9 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
Paterson's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 43.1 ppb (54% of the legal limit, but 287x the EWG guideline) and HAA5 at 25.2 ppb (42% of the legal limit, but 252x 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 0.0689 ppb, which is 3.4x 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) | 41 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 98 PPM | < 300 PPM | 500 PPM | ✓ OK |
| PFAS (total) | 51.59 ppt | — | No total limit | Detected |
| ↳ PFOA | 9.88 ppt | 0 ppt | 4 ppt (2024) | ⚠ Exceeds |
| ↳ PFOS | 6.9 ppt | 0 ppt | 4 ppt (2024) | ⚠ Exceeds |
| Lead | 4 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ✓ Low |
| Chlorine / Chloramine | 1 mg/L | Taste threshold ~1.0 | 4.0 mg/L | ✓ Normal |
| Nitrate | 1.14 mg/L | 5 mg/L | 10 mg/L | ✓ OK |
Recommended Filter for Paterson
PFAS exceed EPA limits (PFOA: 9.88 ppt, PFOS: 6.9 ppt — limit: 4 ppt each). A certified filter reduces these contaminants effectively.
Quick Fix for Chlorine: Shower Filter
At 1 mg/L chlorine, many Paterson residents notice dry skin, brittle hair, and that "pool smell" in the shower. A shower filter installs in 5 minutes, no tools needed.

About Paterson's Water Supply
Water Utility: Passaic Valley Water Commission
Water Source: Passaic River watershed (Surface Water)
Population Served: 310,483
Hardness: 41 PPM (2.4 grains per gallon)
Paterson's drinking water comes from surface sources — Passaic River watershed. 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 310,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Passaic Valley Water Commission's Consumer Confidence Report (CCR) or test your own tap.
