What 11.9 gpg means in Nevada
At this level limescale builds up slowly but steadily. White traces appear on faucets and shower glass within months, and the water heater loses a little efficiency every year. Light protection already pays off.
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.
Como este valor foi obtido
Median of the site-level medians at 94 groundwater monitoring sites (wells and springs — the sources most US public systems draw from) in the USGS National Water Information System (252 individual measurements, 2018-02 → 2023-10). 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 — Nevada
Is 11.9 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 11.9 gpg (203 ppm), water in Nevada is classified as Moderately hard water.
Does Nevada have a limescale problem?
Water in Nevada averages 11.9 gpg — Moderately hard 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 Nevada?
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 Nevada.
Do I need a salt-based water softener at 11.9 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.
