Understanding Monroe County’s Water

Drinking Water Quality Overview

EPA SDWIS

Monroe County's drinking water earned a C grade, scoring 54.8 out of 100. Over the past five years, EPA SDWIS records 3 health-based violations — a small cluster that warrants attention.

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 small share — 7.4% — of assessed waterways are impaired (2 of 27 water bodies) across Monroe County's watersheds. The leading impairment cause is mercury. 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 2026-05-14T13:00:00.000-05:00) puts ALABAMA RIVER at 8.8k cfs — well below its long-term average at 29% 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. Monroe County has limited coverage with 3 active monitoring sites with 13,101 recent measurements on record. Predominant monitoring categories include organics, pesticide and physical. 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 Monroe County

Water Verdict

Monroe County receives a below-average water quality assessment with a grade of C and a score of 54.8 out of 100. Residents should review their utility's Consumer Confidence Report and may want to consider additional water filtration for drinking.

Monroe County has recorded 3 health-based violations, indicating multiple instances where federal contaminant limits or treatment requirements were not met. At 10.6 violations per 100,000 people served, this rate is high and signals significant water quality management issues.

Consumer Guidance

Tap water in Monroe County meets baseline standards but the compliance record shows room for improvement, with a Grade C rating. Monroe County's drinking-water compliance score is 54.8 out of 100. The violation rate for Monroe County is 10.6 per 100,000 people served. Residents who are immunocompromised, pregnant, or have young children may benefit from using an NSF 53-certified filter. Contacting your local utility for the current Consumer Confidence Report will confirm which specific violations were recorded and whether they have been resolved. Mercury is the leading impairment cause in Monroe County's watershed. There are 3 active water-quality monitoring sites in Monroe County. A pipeline streamflow snapshot from the ALABAMA RIVER gauge is also available on this page.

Regional Context

Impairment is determined under the Clean Water Act §303(d): a water body is impaired when it fails to meet state-defined quality standards for designated uses (drinking, recreation, aquatic life). Assessment coverage varies by state; counties without assessed water bodies are not shown.

Frequently Asked Questions

What is the water quality in Monroe County, Alabama?
Monroe County, Alabama has a drinking-water quality grade of C with a score of 54.8/100, based on EPA SDWIS compliance data. The county has 3 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 Monroe County?
Monroe County has 3 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 Monroe County?
EPA ATTAINS assessments under Clean Water Act §303(d) indicate 7.4% of Monroe County's 27 assessed water bodies are classified as impaired (2 impaired). The top reported causes are MERCURY. 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 Monroe County?
EPA's Water Quality Portal records 13,101 measurements from 3 monitoring sites in Monroe County over the past five years. The most frequently measured characteristic groups are Organics, Pesticide, Physical, Nutrient. 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 Monroe County right now?
Monroe County's primary USGS streamgage on the ALABAMA RIVER has a pipeline snapshot of 8,850 cubic feet per second — 29% of the long-term mean of 30,748.66 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 Monroe County water compare to the Alabama average?
