Dureté de l’eau par comté — Vermont
Médianes des mesures relevées dans chaque comté. La dureté varie beaucoup plus à l’intérieur d’un État qu’entre États voisins : c’est de là que vient réellement votre valeur.
| Comté | gpg | mg/L | Fourchette (mg/L) | Classification |
|---|---|---|---|---|
| Orange County | 6 | 103 | 59–183 | Soft water |
| Caledonia County | 8.2 | 140 | 98–166 | Soft water |
| Chittenden County | 4.9 | 83 | 23–221 | Soft water |
| Rutland County | 0.9 | 15 | 5–40 | Soft water |
| Windsor County | 0.9 | 16 | 4–72 | Soft water |
| Bennington County | 0.2 | 3 | 1–5 | Soft water |
| Windham County | 0.2 | 3 | 1–31 | Soft water |
La fourchette correspond aux 10e-90e centiles des mesures locales. Les comtés comptant moins de cinq mesures sont omis plutôt qu’estimés.
What 2.4 gpg means in Vermont
Soft water like this leaves little to no scale. Soap lathers easily, appliances stay clean and your water heater keeps its efficiency. Protection is optional — mostly useful if your utility occasionally blends in harder sources.
What it does to your home
Water heater: even a thin layer of scale insulates the heating element and drives energy use up.
Appliances: dishwashers, washing machines and coffee makers scale up and fail years early.
Fixtures and skin: white spots on faucets and glass, dry skin and dull hair after every shower.
Comment cette valeur a été obtenue
Median of the site-level medians at 60 ambient monitoring sites in the USGS National Water Information System (295 individual measurements, 2005-01 → 2023-07). Each site is collapsed to one value first so that a heavily sampled location cannot skew the state figure; the range shown is the 10th-90th percentile across sites. This describes the raw water resource, not a specific municipal tap after treatment.

Frequently asked questions — Vermont
Is 2.4 gpg considered hard water?
On the US scale, 0–3.5 gpg is soft, 3.5–7 gpg moderately hard, 7–10.5 gpg hard and above 10.5 gpg very hard. At 2.4 gpg (41 ppm), water in Vermont is classified as Soft water.
Does Vermont have a limescale problem?
Water in Vermont averages 2.4 gpg — Soft water. The harder the water, the faster calcium carbonate deposits build up in water heaters, appliances and pipes. Below 3.5 gpg the risk is minimal; above 7 gpg scale becomes a running cost.
How do I find the exact water hardness at my address in Vermont?
Check your utility's annual water quality report (Consumer Confidence Report) or your water bill, or use our free interactive hardness map. Hardness can vary widely between neighboring utilities in Vermont.
Do I need a salt-based water softener at 2.4 gpg?
Not necessarily. Salt softeners add sodium to your water and need constant refills. LIMPEO treats limescale with an electromagnetic field — no salt, no chemicals, no maintenance — and keeps healthy minerals in your drinking water.
