Is Lawrence Township, NJ Tap Water Safe to Drink?
Lawrence Township tap water is legally compliant, but one contaminant exceeds health guidelines. Specifically: PFAS above EPA limits (PFOA: 8 ppt, PFOS: 4.3 ppt — limit is 4 ppt each). A point-of-use filter is recommended for drinking and cooking water.

What Lawrence Township's Water Means for Your Home
Hardness: 55 PPM - Low Concern
Lawrence Township's water is slightly hard at 55 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. Lawrence Township has PFOA at 8 ppt and PFOS at 4.3 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
Lawrence Township's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 22 ppb (28% of the legal limit, but 147x the EWG guideline) and HAA5 at 7.51 ppb (13% of the legal limit, but 75x 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. 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) | 55 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 95 PPM | < 300 PPM | 500 PPM | ✓ OK |
| PFAS (total) | 30.7 ppt | — | No total limit | Detected |
| ↳ PFOA | 8 ppt | 0 ppt | 4 ppt (2024) | ⚠ Exceeds |
| ↳ PFOS | 4.3 ppt | 0 ppt | 4 ppt (2024) | ⚠ Exceeds |
| Lead | 0.7 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ✓ Low |
| Chlorine / Chloramine | 1.1 mg/L | Taste threshold ~1.0 | 4.0 mg/L | ✓ Normal |
| Nitrate | 1.83 mg/L | 5 mg/L | 10 mg/L | ✓ OK |
Recommended Filter for Lawrence Township
PFAS exceed EPA limits (PFOA: 8 ppt, PFOS: 4.3 ppt — limit: 4 ppt each). A certified filter reduces these contaminants effectively.
Quick Fix for Chlorine: Shower Filter
At 1.1 mg/L chlorine, many Lawrence Township residents notice dry skin, brittle hair, and that "pool smell" in the shower. A shower filter installs in 5 minutes, no tools needed.

About Lawrence Township's Water Supply
Water Utility: Trenton Water Works
Water Source: Delaware River + wells (Surface Water)
Population Served: 8,655
Hardness: 55 PPM (3.2 grains per gallon)
Lawrence Township's drinking water comes from surface sources — Delaware River + wells. 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 9,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Trenton Water Works's Consumer Confidence Report (CCR) or test your own tap.
