Troy tap water is legally compliant, but one contaminant exceeds health guidelines. Specifically: lead at 34.7 ppb (above the EPA action level of 15 ppb). A point-of-use filter is recommended for drinking and cooking water.

How Troy Compares
Troy's water is 71% softer than the national average of 138 PPM - ranking in the bottom 76% for hardness nationwide. Most homes here do not need a softener. Within New York, it ranks #21 of 37 cities (35% below the state average of 62 PPM). Among cities (50k-100k), Troy ranks #214 of 258 for hardness.
What Troy's Water Means for Your Home
Hardness: 40 PPM - Low Concern
Troy's water is slightly hard at 40 PPM. Most households won't notice any issues at this level. Scale buildup is minimal, and a water softener would be overkill. Troy is softer than 76% of US cities. If you're thinking about water treatment, contaminant filtration is where to focus your money, not softening.
Contaminants & Safety
Lead is the main concern here. At 34.7 ppb, Troy's average is well above the health guideline of zero — there is no safe level of lead, especially for children. Lead typically enters your water from old pipes, not the source itself. Quick fix: run cold water for 30 seconds before drinking. Better fix: a certified lead-reduction filter (NSF/ANSI Standard 53) at your kitchen faucet. If your home was built before 1986, testing is strongly recommended.
What's in the Treatment Process
Troy's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 68.2 ppb (85% of the legal limit, but 455x the EWG guideline) and HAA5 at 34.1 ppb (57% of the legal limit, but 341x 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 0.118 ppb, which is 5.9x 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) | 40 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 65 PPM | < 300 PPM | 500 PPM | ✓ OK |
| PFAS (total) | 0 ppt | — | No total limit | ✓ ND |
| ↳ PFOA | 0 ppt | 0 ppt | 4 ppt (2024) | ✓ OK |
| ↳ PFOS | 0 ppt | 0 ppt | 4 ppt (2024) | ✓ OK |
| Lead | 34.7 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ⚠ Exceeds |
| Chlorine / Chloramine | 1.2 mg/L | Taste threshold ~1.0 | 4.0 mg/L | ✓ Normal |
| Nitrate | 0.123 mg/L | 5 mg/L | 10 mg/L | ✓ OK |
Recommended Filter for Troy
Lead at 34.7 ppb exceeds the 15 ppb action level. A certified filter reduces these contaminants effectively.
Quick Fix for Chlorine: Shower Filter
At 1.2 mg/L chlorine, many Troy residents notice dry skin, brittle hair, and that "pool smell" in the shower. A shower filter installs in 5 minutes, no tools needed.
How to Test Your Water in Troy
Lead enters water from your home's plumbing, not the treatment plant — so Troy's city-wide average of 34.7 ppb may not match your tap. Testing your specific faucet is the only way to know. Run cold water for 30 seconds before collecting a sample.

About Troy's Water Supply
Water Utility: City of Troy Water
Water Source: Tomhannock Reservoir (Surface Water)
Population Served: 51,401
Hardness: 40 PPM (2.3 grains per gallon)
Troy's drinking water comes from surface sources — Tomhannock Reservoir. 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 51,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Troy Water's Consumer Confidence Report (CCR) or test your own tap.
