Well water hardness in Banner County, Nebraska
9.1 gpg hard
Private wells in Banner County typically give hard water: the median well sampled by the U.S. Geological Survey has 9.1 gpg (156 mg/L as CaCO₃).
Wells differ a lot, even next door: one in ten sampled wells had less than 39 mg/L and one in ten more than 272 mg/L. The figure comes from 53 wells and 63 samples taken between 1991 and 2002 (half of them by 2000).
Most samples are older than ten years. Groundwater hardness comes from the rock the well is drilled into and changes slowly, but your own well can be quite different, so treat this as a regional indication and test your water.
What this hardness means for a well household
- Fast scale on taps, shower screens and kettle; white spots on glassware.
- Water heater: efficiency loss and element failures within years if unprotected.
- Dry skin and dull hair after showering are common.
- Softener recommended; jug or reverse osmosis for drinking.
How to test your well in Nebraska
Hardness is only one part of a well test. Federal health agencies advise every private well owner to test regularly:
- Test a private well every year for total coliform bacteria, nitrates, total dissolved solids and pH; test more often if young children, older adults or a pregnant or nursing person live in the home. (US EPA, Protect Your Home's Water)
- Test at least once a year and ask the local health department which other germs or chemicals matter where you live. (CDC, Guidelines for Testing Well Water)
- Sample your private well drinking water every year; nitrate test kits can be ordered from the state public health laboratory at any time. (Nebraska Department of Water, Energy, and Environment (2024-03-08))
Use a certified laboratory: Nebraska DHHS list of certified laboratories (certification numbers and certified analytes).
Testing is your own responsibility: no state agency samples existing private wells routinely.

If no local lab suits you, mail-in kits from certified labs test a wider panel at home; they cost more than a state or county lab.
Treating hard well water
Most households with hard well water install an ion-exchange softener. Test iron and manganese first: above about 0.3 mg/L iron a softener alone is not enough and an iron filter goes in front of it.

FAQ
How hard is well water in Banner County, Nebraska?
The median well sampled by the USGS in Banner County has 9.1 gpg (156 mg/L as CaCO₃), which is hard. One in ten wells had less than 39 mg/L and one in ten more than 272 mg/L.
Is my own well the same?
Not necessarily. Hardness depends on the rock layer your well draws from and on its depth, so neighbouring wells can differ by a factor of two or more. Only a test of your own water tells you.
How often should I test my well in Nebraska?
Every year for coliform bacteria, nitrate, total dissolved solids and pH (EPA and CDC advice), and after floods, repairs or a change in taste or smell. Hardness, iron and manganese once, and again before you buy a softener.
Do I need a water softener for my well?
Recommended if you have a water heater, boiler or tankless unit: it saves repairs and detergent.
Where does this figure come from?
From 63 samples of 53 wells measured by the U.S. Geological Survey between 1991 and 2002, retrieved from the Water Quality Portal. We publish a county only when at least 10 wells were sampled.
Source and method
Computed by Water Hardness Atlas from USGS National Water Information System samples (characteristic "Hardness, Ca, Mg", sites of type well, samples since 1980), retrieved 2026-10-29 through the Water Quality Portal. For each well we take the median of its samples, then the median of all wells in the county; wells above 1,000 mg/L (oil, gas or mine brines) are left out. USGS data are in the U.S. public domain.
