Is Suffern, NY Tap Water Safe to Drink?
Suffern tap water is legally compliant, but one contaminant exceeds health guidelines. Specifically: PFAS above EPA limits (PFOA: 7.4 ppt, PFOS: 5.8 ppt — limit is 4 ppt each). A point-of-use filter is recommended for drinking and cooking water.

How Suffern Compares
Suffern's water is 57% 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 York, it ranks #12 of 37 cities (3% below the state average of 62 PPM). Among smaller cities, Suffern ranks #155 of 288 for hardness.
What Suffern's Water Means for Your Home
Hardness: 60 PPM - Low Concern
Suffern's water is moderately hard at 60 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. The minerals come from the local aquifer geology. 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. Suffern has PFOA at 7.4 ppt and PFOS at 5.8 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
Even though Suffern draws from groundwater, the treatment process still generates disinfection byproducts: TTHMs at 9.65 ppb and HAA5 at 2.75 ppb. Groundwater typically needs less treatment than surface water, but when organic compounds are present in the aquifer, chlorination creates the same byproducts. All levels are within legal limits, though above the stricter EWG health guidelines.
Chromium-6 is naturally present in Suffern's aquifer geology at 0.0948 ppb — 4.7x the EWG health guideline. There's no federal legal limit for chromium-6 specifically (only total chromium), which is why EWG tracks it separately. 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) | 60 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 100 PPM | < 300 PPM | 500 PPM | ✓ OK |
| PFAS (total) | 23.55 ppt | — | No total limit | Detected |
| ↳ PFOA | 7.4 ppt | 0 ppt | 4 ppt (2024) | ⚠ Exceeds |
| ↳ PFOS | 5.8 ppt | 0 ppt | 4 ppt (2024) | ⚠ Exceeds |
| Lead | 2 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ✓ Low |
| Chlorine / Chloramine | 0.9 mg/L | Taste threshold ~1.0 | 4.0 mg/L | ✓ Normal |
| Nitrate | 1.44 mg/L | 5 mg/L | 10 mg/L | ✓ OK |

About Suffern's Water Supply
Water Utility: Suez Water New York
Water Source: Ramapo River watershed (Groundwater)
Population Served: 12,000
Hardness: 60 PPM (3.5 grains per gallon)
Suffern draws its drinking water from groundwater sources — Ramapo River watershed. Groundwater typically requires less treatment than surface water because the earth acts as a natural filter. The tradeoff: dissolved minerals from underground rock formations, which is why mineral content varies by aquifer depth and geology. The geological profile determines hardness, iron, and trace mineral levels. The system serves 12,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Suez Water New York's Consumer Confidence Report (CCR) or test your own tap.
