What Charlotte's Water Means for Your Home
Hardness: 50 PPM - Low Concern
Charlotte'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
Lead levels deserve attention. At 6 ppb, Charlotte is above the ideal of zero, though below the EPA action level of 15 ppb (dropping to 10 ppb in November 2027 under the Lead and Copper Rule Improvements). The lead typically comes from aging service lines or interior plumbing, not the treatment plant. A point-of-use filter certified for lead at the kitchen faucet is a practical safeguard, especially in older homes.
What's in the Treatment Process
Charlotte's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 40.8 ppb (51% of the legal limit, but 272x the EWG guideline) and HAA5 at 15.3 ppb (26% of the legal limit, but 153x 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 0.0668 ppb, which is 3.3x 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 | 80 PPM | < 300 PPM | 500 PPM | ✓ OK |
| PFAS (total) | 10.85 ppt | — | No total limit | Detected |
| ↳ PFOA | 0 ppt | 0 ppt | 4 ppt (2024) | ✓ OK |
| ↳ PFOS | 0 ppt | 0 ppt | 4 ppt (2024) | ✓ OK |
| Lead | 6 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ⚠ Elevated |
| Chlorine / Chloramine | 1.3 mg/L | Taste threshold ~1.0 | 4.0 mg/L | ✓ Normal |
| Nitrate | Not reported | 5 mg/L | 10 mg/L | N/A |
Quick Fix for Chlorine: Shower Filter
At 1.3 mg/L chlorine, many Charlotte 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 Charlotte
Lead enters water from your home's plumbing, not the treatment plant — so Charlotte's city-wide average of 6 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 Charlotte's Water Supply
Water Utility: Charlotte Water
Water Source: Mountain Island Lake + Catawba River (Surface Water)
Population Served: 1,163,701
Hardness: 50 PPM (2.9 grains per gallon)
Charlotte's drinking water comes from surface sources — Mountain Island Lake + Catawba River. 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 1.2 million residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Charlotte Water's Consumer Confidence Report (CCR) or test your own tap.
