Understanding Reno County’s Water

Drinking Water Quality Overview

EPA SDWIS

Reno County's water systems carry a failing grade, scoring 15.8 out of 100. Over the past five years, EPA SDWIS records 92 health-based violations — a pattern that public water utilities are required to disclose and correct.

River & Streamflow Status

USGS NWIS

USGS NWIS gauge data (as of 2026-05-14T13:30:00.000-05:00) puts ARKANSAS R at 101.0 cfs — well below its long-term average at 21% 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. Reno County has limited coverage with 3 active monitoring sites with 5,236 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 Reno County

Water Verdict

Reno County receives a poor water quality assessment with a grade of F and a score of 15.8 out of 100. The water supply has documented quality issues. Residents are strongly encouraged to use filtered or bottled water for drinking and to stay informed about utility improvement plans.

Violation Context

Reno County has recorded 92 health-based violations, indicating multiple instances where federal contaminant limits or treatment requirements were not met. At 187.1 violations per 100,000 people served, this rate is high and signals significant water quality management issues.

Consumer Guidance

Reno County has a Grade F compliance record with 92 health-based violations — among the highest levels in the country. Reno County's drinking-water compliance score is 15.8 out of 100. Residents are strongly advised to use a certified NSF 58 reverse-osmosis filter or bottled water for all drinking and cooking until violations are corrected. Contacting the Kansas Department of Environmental Quality or Health can expedite utility compliance action. There are 3 active water-quality monitoring sites in Reno County. A pipeline streamflow snapshot from the ARKANSAS R gauge is also available on this page.

Regional Context

Reno County has poorer water quality than the average county in Kansas. Its water score is 26.8 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 Reno County, Kansas?
Reno County, Kansas has a drinking-water quality grade of F with a score of 15.8/100, based on EPA SDWIS compliance data. The county has 92 health-based drinking water violations over the past 5 years. Watershed health, monitoring records, and streamflow snapshots are reported separately on this page.
Are there any water violations in Reno County?
Reno County has 92 health-based drinking water violations recorded by the EPA over the past 5 years. Health-based violations indicate instances where contaminant levels exceeded EPA Maximum Contaminant Levels (MCLs). Violations may have been resolved — check with your local water utility for current status.
How much water-quality monitoring happens in Reno County?
EPA's Water Quality Portal records 5,236 measurements from 3 monitoring sites in Reno County over the past five years. The most frequently measured characteristic groups are Physical, Nutrient, Inorganics, Minor, Metals. 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 Reno County right now?
Reno County's primary USGS streamgage on the ARKANSAS R has a pipeline snapshot of 101 cubic feet per second — 21% of the long-term mean of 486.61 cfs. This is well below typical — often a signal of drought stress on source water. For the latest gauge feed, visit waterdata.usgs.gov.
How does Reno County water compare to the Kansas average?
Reno County's SDWIS water quality score of 15.8/100 is lower than the Kansas state average of 42.6. The average water quality grade across Kansas is D, based on data from 105 counties with available SDWIS data.
Is tap water safe to drink in Reno County?
Based on EPA SDWIS data, Reno County has a water quality grade of F (15.8/100). This indicates below-average compliance with significant violations. Residents may want to consider home water filtration or independent testing. The grade speaks to the public water system, not the watershed — for watershed-level concerns, see the Watershed Health zone. For the most up-to-date information, contact your local water utility or review your Consumer Confidence Report (CCR).
Why does Reno County have so many water violations?
Reno County has 92 health-based drinking water violations on record from the EPA SDWIS database. A higher violation count can result from aging infrastructure, underfunded water utilities, agricultural runoff contamination, or industrial pollution. Counties with more water systems may also see more violations simply due to scale. Residents concerned about water quality should consider independent water testing and home filtration systems.
How does Reno County rank for water quality in Kansas?
Reno County ranks #72 out of 105 counties in Kansas by SDWIS water quality score (1 = best). With a score of 15.8/100, it falls in the bottom third of counties statewide. The ranking reflects EPA SDWIS compliance only — not watershed impairment, monitoring density, or streamflow, which are tracked separately on this page.
