Understanding Stanton County’s Water

Drinking Water Quality Overview

EPA SDWIS

Stanton County's drinking water received a D grade, scoring 43.9 out of 100. Over the past five years, EPA SDWIS records 1 health-based violation — a single incident worth monitoring.

Watershed Conditions

EPA ATTAINS

Under the Clean Water Act §303(d), EPA ATTAINS tracks whether waterways meet quality standards for drinking, recreation, and aquatic life (reporting cycle: 2022). A substantial 53.3% of assessed waterways are impaired (8 of 15 water bodies) across Stanton County's watersheds. The leading impairment causes are escherichia coli (e. coli) and cause unknown. Impairment does not mean tap water is unsafe — it measures ambient waterway conditions upstream of treatment, not finished drinking water.

River & Streamflow Status

USGS NWIS

USGS NWIS gauge data (as of 2026-05-14T13:45:00.000-05:00) puts Elkhorn River at 467.0 cfs — well below its long-term average at 46% of mean — low-flow conditions worth noting for water-dependent ecosystems. Streamflow is a leading indicator of drought stress, sediment load, and dilution capacity: low flows concentrate pollutants and warm water temperatures, stressing aquatic life and, in surface-water-dependent systems, the source water quality for treatment plants.

Monitoring Network

EPA WQP

EPA's Water Quality Portal (WQP) aggregates monitoring data from federal, state, and tribal agencies. Stanton County has limited coverage with 7 active monitoring sites with 1,189 recent measurements on record. Predominant monitoring categories include physical and nutrient. More monitoring sites generally indicate greater scientific attention to local water conditions — and provide the baseline data that regulators use to set future impairment listings.

Editorial advisory

What the data suggests for Stanton County

Water Verdict

Stanton County receives a below-average water quality assessment with a grade of D and a score of 43.9 out of 100. Residents should review their utility's Consumer Confidence Report and may want to consider additional water filtration for drinking.

Violation Context

Stanton County has recorded 1 health-based violation, meaning the water system experienced at least one exceedance of federal contaminant limits or treatment requirements. At 25.4 violations per 100,000 people served, this rate is high and signals significant water quality management issues.

Consumer Guidance

Stanton County's drinking-water compliance is below average with a Grade D, indicating repeated or unresolved violations in the recent record. Stanton County's drinking-water compliance score is 43.9 out of 100. The violation rate for Stanton County is 25.4 per 100,000 people served. Residents are encouraged to use an NSF 53 or NSF 58-certified filter for drinking and cooking water until the underlying violations are resolved. Running tap water for 30 seconds before use and avoiding older lead-pipe connections can also reduce exposure risk. The current Consumer Confidence Report from your utility will specify the contaminants of concern. E. coli is the leading impairment cause in Stanton County's watershed. There are 7 active water-quality monitoring sites in Stanton County. A pipeline streamflow snapshot from the Elkhorn River gauge is also available on this page.

Regional Context

Stanton County has poorer water quality than the average county in Nebraska. Its water score is 14.2 points lower than the state average, suggesting more challenges with contamination control or infrastructure than neighboring counties.

Frequently Asked Questions

What is the water quality in Stanton County, Nebraska?
Stanton County, Nebraska has a drinking-water quality grade of D with a score of 43.9/100, based on EPA SDWIS compliance data. The county has 1 health-based drinking water violation over the past 5 years. Watershed health, monitoring records, and streamflow snapshots are reported separately on this page.
Are there any water violations in Stanton County?
Stanton County has 1 health-based drinking water violation recorded by the EPA over the past 5 years. Health-based violations indicate instances where contaminant levels exceeded EPA Maximum Contaminant Levels (MCLs).

Impairment means the water body fails to meet state quality standards for at least one designated use — drinking water source, recreation, aquatic life, or fish consumption. Note: watershed impairment doesn't always translate to tap-water issues; treatment plants can remove most regulated contaminants.
How much water-quality monitoring happens in Stanton County?
EPA's Water Quality Portal records 1,189 measurements from 7 monitoring sites in Stanton County over the past five years. The most frequently measured characteristic groups are Physical, Nutrient, Microbiological. Each measurement is a single sample analyzed for one characteristic (E. coli, pH, dissolved oxygen, etc.). High monitoring density means more scientific evidence behind any reported signal — it does not by itself indicate water quality.
What's happening with rivers in Stanton County right now?
Stanton County's primary USGS streamgage on the Elkhorn River has a pipeline snapshot of 467 cubic feet per second — 46% of the long-term mean of 1,016.2 cfs. This is well below typical — often a signal of drought stress on source water. For the latest gauge feed, visit waterdata.usgs.gov.
