What Freeport's Water Means for Your Home
Hardness: 35 PPM - Low Concern
Freeport'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. Freeport 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, Freeport's water is within EPA guidelines for regulated contaminants. Chlorine sits at 1.1 mg/L — normal for municipal systems, but enough to notice. 4 contaminants exceed EWG's stricter health guidelines, though all are within legal limits. If your water tastes like a pool or your skin feels dry after showers, a whole-house carbon filter is the simplest fix. A shower filter is a quick, affordable starting point that most people notice immediately. Want the full picture? Request your utility's annual Consumer Confidence Report for neighborhood-level data.
What's in the Treatment Process
Even though Freeport draws from groundwater, the treatment process still generates disinfection byproducts: TTHMs at 0.193 ppb and HAA5 at 5.56 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. 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 | 1.1 mg/L | Taste threshold ~1.0 | 4.0 mg/L | ✓ Normal |
| Nitrate | Not reported | 5 mg/L | 10 mg/L | N/A |
Good news for Freeport 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.
Quick Fix for Chlorine: Shower Filter
At 1.1 mg/L chlorine, many Freeport residents notice dry skin, brittle hair, and that "pool smell" in the shower. A shower filter installs in 5 minutes, no tools needed.

About Freeport's Water Supply
Water Utility: Freeport Water Department
Water Source: Long Island Aquifer (Groundwater)
Population Served: 45,000
Hardness: 35 PPM (2 grains per gallon)
Freeport 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 45,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request Freeport Water Department's Consumer Confidence Report (CCR) or test your own tap.
