Is Perth Amboy, NJ Tap Water Safe to Drink?
Perth Amboy tap water is legally compliant, but one contaminant exceeds health guidelines. Specifically: PFAS above EPA limits (PFOA: 15.33 ppt, PFOS: 4.63 ppt — limit is 4 ppt each). A point-of-use filter is recommended for drinking and cooking water.

Within New Jersey, it ranks #10 of 22 cities (11% above the state average of 45 PPM). Among cities (50k-100k), Perth Amboy ranks #198 of 258 for hardness.
What Perth Amboy's Water Means for Your Home
Hardness: 50 PPM - Low Concern
Perth Amboy's water is slightly hard at 50 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 a serious concern here. Perth Amboy has PFOA at 15.33 ppt and PFOS at 4.63 ppt — the EPA's 2024 limit is 4 ppt for PFOA and PFOS individually. PFAS don't break down in your body or the environment. Research links long-term exposure to increased cancer risk, thyroid issues, and immune system problems. The fix: a whole-house activated carbon filter or a point-of-use reverse osmosis system. Look for NSF P473 certification — that's the standard that specifically tests for PFAS removal.
What's in the Treatment Process
Perth Amboy's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 62.9 ppb (79% of the legal limit, but 420x the EWG guideline) and HAA5 at 19.7 ppb (33% of the legal limit, but 197x 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 0.156 ppb, which is 7.8x 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) | 50 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 65 PPM | < 300 PPM | 500 PPM | ✓ OK |
| PFAS (total) | 48.85 ppt | — | No total limit | Detected |
| ↳ PFOA | 15.33 ppt | 0 ppt | 4 ppt (2024) | ⚠ Exceeds |
| ↳ PFOS | 4.63 ppt | 0 ppt | 4 ppt (2024) | ⚠ Exceeds |
| Lead | 1.8 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ✓ Low |
| Chlorine / Chloramine | 0.4 mg/L | Taste threshold ~1.0 | 4.0 mg/L | ✓ Normal |

About Perth Amboy's Water Supply
Water Utility: Middlesex Water Company
Water Source: Runyon Watershed & Farrington Lake (Surface Water)
Population Served: 52,328
Hardness: 50 PPM (2.9 grains per gallon)
Perth Amboy's drinking water comes from surface sources — Runyon Watershed & Farrington Lake. 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 Middlesex Water Company's Consumer Confidence Report (CCR) or test your own tap.
