What Hickory's Water Means for Your Home
Hardness: 45 PPM - Low Concern
Hickory's water is slightly hard at 45 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 is the main concern here. At 10 ppb, Hickory'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
Hickory's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 43.8 ppb (55% of the legal limit, but 292x the EWG guideline) and HAA5 at 23.1 ppb (39% of the legal limit, but 231x 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 0.119 ppb, which is 6x 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) | 45 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 62 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 | 10 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ⚠ Elevated |
| Chlorine / Chloramine | 1.4 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 1.4 mg/L chlorine, many Hickory 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 Hickory
Lead enters water from your home's plumbing, not the treatment plant — so Hickory's city-wide average of 10 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 Hickory's Water Supply
Water Utility: City of Hickory Water
Water Source: Lake Hickory & Henry Fork River (Surface Water)
Population Served: 75,654
Hardness: 45 PPM (2.6 grains per gallon)
Hickory's drinking water comes from surface sources — Lake Hickory & Henry Fork 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 76,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Hickory Water's Consumer Confidence Report (CCR) or test your own tap.
