Understanding Bedford County’s Water

Drinking Water Quality Overview

EPA SDWIS

Bedford County's water systems carry a failing grade, scoring 37.5 out of 100. Over the past five years, EPA SDWIS records 25 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 notable 23.6% of assessed waterways carry an impairment designation (21 of 89 water bodies) across Bedford County's watersheds. The leading impairment causes are escherichia coli (e. coli) and sedimentation/siltation. Impairment does not mean tap water is unsafe — it measures ambient waterway conditions upstream of treatment, not finished drinking water.

Monitoring Network

EPA WQP

EPA's Water Quality Portal (WQP) aggregates monitoring data from federal, state, and tribal agencies. Bedford County has moderate coverage with 42 active monitoring sites with 4,399 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.

Frequently Asked Questions

What is the water quality in Bedford County, Tennessee?
Bedford County, Tennessee has a drinking-water quality grade of F with a score of 37.5/100, based on EPA SDWIS compliance data. The county has 25 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 Bedford County?
Bedford County has 25 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 Bedford County?
EPA ATTAINS assessments under Clean Water Act §303(d) indicate 23.6% of Bedford County's 89 assessed water bodies are classified as impaired (21 impaired). The top reported causes are ESCHERICHIA COLI (E. COLI), SEDIMENTATION/SILTATION, ALTERATION IN STREAM-SIDE OR LITTORAL VEGETATIVE COVERS. 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 Bedford County?
EPA's Water Quality Portal records 4,399 measurements from 42 monitoring sites in Bedford 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 Bedford County right now?
Bedford County's primary USGS streamgage on the DUCK RIVER has a pipeline snapshot of 162 cubic feet per second. Flow is within typical range for this gauge. For the latest gauge feed, visit waterdata.usgs.gov.
How does Bedford County water compare to the Tennessee average?
Bedford County's SDWIS water quality score of 37.5/100 is lower than the Tennessee state average of 71.3. The average water quality grade across Tennessee is C, based on data from 95 counties with available SDWIS data.
Is tap water safe to drink in Bedford County?
Based on EPA SDWIS data, Bedford County has a water quality grade of F (37.5/100). 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 Bedford County have so many water violations?
Bedford County has 25 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 Bedford County rank for water quality in Tennessee?
Bedford County ranks #82 out of 95 counties in Tennessee by SDWIS water quality score (1 = best). With a score of 37.5/100, 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.
