What 17.4 gpg means in Dakota du Nord
This is hard water: visible scale on fixtures within weeks, clogged shower heads, stiff laundry and a water heater working overtime. Anti-scale protection is strongly recommended.
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 88 groundwater monitoring sites (wells and springs — the sources most US public systems draw from) in the USGS National Water Information System (110 individual measurements, 2018-07 → 2023-08). 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 — Dakota du Nord
Is 17.4 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 17.4 gpg (298 ppm), water in Dakota du Nord is classified as Hard water.
