What Huntington's Water Means for Your Home
Hardness: 35 PPM - Low Concern
Huntington's water is slightly hard at 35 PPM. Most households won't notice any issues at this level. Scale buildup is minimal, and a water softener would be overkill. Huntington is softer than 79% of US cities. If you're thinking about water treatment, contaminant filtration is where to focus your money, not softening.
Contaminants & Safety
Beyond hardness, Huntington's water is within EPA guidelines for regulated contaminants. Chlorine is relatively low at 0.9 mg/L. That said, 9 contaminants exceed EWG's stricter health guidelines — these are legal but worth understanding.. Want the full picture?

What's in the Treatment Process
Even though Huntington draws from groundwater, the treatment process still generates disinfection byproducts: TTHMs at 2.68 ppb and HAA5 at 10 ppb. Groundwater typically needs less treatment than surface water, but when organic compounds are present in the aquifer, chlorination creates the same byproducts. All levels are within legal limits, though above the stricter EWG health guidelines.
Chromium-6 is naturally present in Huntington's aquifer geology at 0.592 ppb — 30x the EWG health guideline. There's no federal legal limit for chromium-6 specifically (only total chromium), which is why EWG tracks it separately. 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) | 35 PPM | < 60 PPM | No federal limit | ✓ OK |
| Total Dissolved Solids | 60 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 | 1.3 ppb | 0 ppb (no safe level) | 15 ppb (10 ppb in 2027) | ✓ Low |
| Chlorine / Chloramine | 0.9 mg/L | Taste threshold ~1.0 | 4.0 mg/L | ✓ Normal |
| Nitrate | 3.33 mg/L | 5 mg/L | 10 mg/L | ✓ OK |
Good news for Huntington residents. Your water quality is generally good. Most homes in this area do not need a water softener. If you have concerns about lead (especially in buildings constructed before 1986) or chlorine taste, a point-of-use filter is the most practical and cost-effective solution.

About Huntington's Water Supply
Water Utility: Huntington Water District
Water Source: Long Island Aquifer (Groundwater)
Population Served: 81,760
Hardness: 35 PPM (2 grains per gallon)
Huntington draws its drinking water from groundwater sources — Long Island Aquifer. Groundwater typically requires less treatment than surface water because the earth acts as a natural filter. The tradeoff: dissolved minerals from underground rock formations, which is why mineral content varies by aquifer depth and geology. The geological profile determines hardness, iron, and trace mineral levels. The system serves 82,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Huntington Water District's Consumer Confidence Report (CCR) or test your own tap.
