Understanding Rogers County’s Water

Drinking Water Quality Overview

EPA SDWIS

Rogers County's water systems carry a failing grade, scoring 15.9 out of 100. Over the past five years, EPA SDWIS records 139 health-based violations — a pattern that public water utilities are required to disclose and correct.

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 large majority — 100.0% — of assessed waterways are impaired (2 of 2 water bodies) across Rogers County's watersheds. The leading impairment causes are chlorophyll-a and turbidity. 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 2026-05-14T13:30:00.000-05:00) puts Verdigris River at 472.0 cfs — well below its long-term average at 10% 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. Rogers County has limited coverage with 7 active monitoring sites with 10,602 recent measurements on record. Predominant monitoring categories include physical and not assigned. 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 Rogers County

Water Verdict

Rogers County, Oklahoma receives a poor water quality assessment with a grade of F and a score of 15.9 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. Separately, EPA ATTAINS assessments cover 2 water bodies in the county's watershed, with 100.0% listed as impaired under the Clean Water Act — a source-water measure that is tracked independently of tap-water compliance. At the most recent USGS reading, local streamflow was below its historical mean at 10.2% — worth watching in drier seasons.

Violation Context

EPA SDWIS records for Rogers County, Oklahoma show 139 health-based violations, indicating multiple instances where federal contaminant limits or treatment requirements were not met. At 184.8 violations per 100,000 people served, this rate is high and signals significant water quality management issues. This compliance record sits alongside an unusually deep monitoring archive: 10,602 water-quality results have been logged across the county in the EPA Water Quality Portal over the past five years.

Consumer Guidance

Rogers County has a Grade F compliance record with 139 health-based violations — among the highest levels in the country. Rogers County's drinking-water compliance score is 15.9 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 Oklahoma Department of Environmental Quality or Health can expedite utility compliance action. Chlorophyll-A is the leading impairment cause in Rogers County's watershed. There are 7 active water-quality monitoring sites in Rogers County. A pipeline streamflow snapshot from the Verdigris River gauge is also available on this page.

Regional Context

Rogers County has water quality close to the average county in Oklahoma. Its water score is within 0.1 points of the state average, meaning its overall water system performance is broadly representative of Oklahoma as a whole.

Frequently Asked Questions

What is the water quality in Rogers County, Oklahoma?
Rogers County, Oklahoma has a drinking-water quality grade of F with a score of 15.9/100, based on EPA SDWIS compliance data. The county has 139 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 Rogers County?
Rogers County has 139 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 healthy are the watersheds in Rogers County?
EPA ATTAINS assessments under Clean Water Act §303(d) indicate 100.0% of Rogers County's 2 assessed water bodies are classified as impaired (2 impaired). The top reported causes are CHLOROPHYLL-A, TURBIDITY, DISSOLVED OXYGEN. 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 Rogers County?
EPA's Water Quality Portal records 10,602 measurements from 7 monitoring sites in Rogers County over the past five years. The most frequently measured characteristic groups are Physical, Not Assigned, Biological, Algae, Phytoplankton. 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 Rogers County right now?
Rogers County's primary USGS streamgage on the Verdigris River has a pipeline snapshot of 472 cubic feet per second — 10% of the long-term mean of 4,617.02 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 Rogers County water compare to the Oklahoma average?
Rogers County's SDWIS water quality score of 15.9/100 is higher than the Oklahoma state average of 15.8. The average water quality grade across Oklahoma is F, based on data from 77 counties with available SDWIS data.
Is tap water safe to drink in Rogers County?
Based on EPA SDWIS data, Rogers County has a water quality grade of F (15.9/100). 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 Rogers County have so many water violations?
Rogers County has 139 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 Rogers County rank for water quality in Oklahoma?
Rogers County ranks #26 out of 77 counties in Oklahoma by SDWIS water quality score (1 = best). With a score of 15.9/100, it falls in the top 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.
