Nebraska Water Quality (2026)
Last updated: June 2026
Agricultural runoff drives nitrate concerns in many Nebraska utilities; some surface systems also see elevated TTHM.
Our Nebraska coverage focuses on the 4 metros below. Each city page lists the utility's water source, hardness in grains per gallon, contaminants flagged above EWG's stricter health guideline, and the whole-house system that fits that specific profile, not a generic recommendation copied across the state.
Common contaminants flagged across Nebraska
Across the Nebraska cities we cover, these are the contaminants most often reported above EWG's health guideline. None exceed federal EPA legal limits.
- nitrate
- nitrate (agriculture)
- atrazine (agriculture)
- TTHM reported far above EWG guideline (~241x in some samples)
Cities we cover in Nebraska
| City | Hardness | Flagged above EWG guideline | Best fit |
|---|---|---|---|
| Bellevue | - | nitrate | Softener + POU RO |
| Grand Island | - | nitrate (agriculture) | Softener + POU RO |
| Lincoln | - | nitrate, atrazine (agriculture) | Softener + POU RO |
| Omaha | Moderate | TTHM reported far above EWG guideline (~241x in some samples) | Catalytic carbon filter |
Recommended systems for Nebraska
Most Nebraska homes benefit from a layered setup: whole-house carbon for chlorine and taste, a softener if your CCR shows hardness above 7 gpg, and a certified under-sink RO at the kitchen tap if lead, PFAS, nitrate or arsenic are flagged.

+Is Nebraska tap water safe to drink?
Yes, by federal standards: the cities on this page all meet every EPA legal limit. The contaminants we flag sit above EWG's stricter, non-enforceable health guideline, which is the benchmark most homeowners use when deciding whether to filter further at home.
+Why is Nebraska water hard?
Hardness comes from calcium and magnesium picked up as water moves through local geology. In Nebraska, the values vary city by city, see the table above for your metro. Anything above 7 grains per gallon is considered hard and is where a softener starts to make a noticeable difference.
+Do I need a softener or a filter in Nebraska?
Different problems, different tools. A whole-house carbon filter handles chlorine, chloramine and taste. A softener handles scale from hard water. Many Nebraska homes benefit from both, and a kitchen-tap RO if lead, PFAS or nitrate appear on your CCR.
