Understanding Baldwin County’s Water

Drinking Water Quality Overview

EPA SDWIS

Baldwin County earns a B grade for drinking water quality, scoring 65.3 out of 100. Over the past five years, EPA SDWIS records 10 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 substantial 38.2% of assessed waterways are impaired (34 of 89 water bodies) across Baldwin County's watersheds. The leading impairment causes are mercury and enterococcus. 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 2026-05-14T14:00:00.000-05:00) puts STYX RIVER at 580.0 cfs — flowing above its historical average at 134% of mean. 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. Baldwin County has extensive coverage with 144 active monitoring sites with 55,050 recent measurements on record. Predominant monitoring categories include physical and inorganics, minor, metals. 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 Baldwin County

Water Verdict

Baldwin County receives a fair water quality assessment with a grade of B and a score of 65.3 out of 100. The water supply meets baseline federal standards, but there may be periods of elevated contaminant levels or infrastructure concerns worth monitoring.

Violation Context

Baldwin County has recorded 10 health-based violations, indicating multiple instances where federal contaminant limits or treatment requirements were not met. At 3.3 violations per 100,000 people served, this rate is moderate and suggests recurring water quality challenges.

Consumer Guidance

Tap water in Baldwin County meets baseline safety standards, though the compliance record shows some violations worth watching. Baldwin County's drinking-water compliance score is 65.3 out of 100. The violation rate for Baldwin County is 3.3 per 100,000 people served. Running tap water for 30 seconds before drinking can reduce any localized lead exposure from household plumbing. Requesting your utility's most recent Consumer Confidence Report is the fastest way to identify which specific contaminants were flagged. Mercury is the leading impairment cause in Baldwin County's watershed. With 144 active water-quality monitoring sites in Baldwin County, data coverage is strong. A pipeline streamflow snapshot from the STYX RIVER gauge is also available on this page.

Regional Context

Baldwin County has water quality close to the average county in Alabama. Its water score is within 3.5 points of the state average, meaning its overall water system performance is broadly representative of Alabama as a whole.

Advisory text summarizes county-level public records and is not a replacement for your utility's current Consumer Confidence Report or direct local notices.

Frequently Asked Questions

What is the water quality in Baldwin County, Alabama?
Baldwin County, Alabama has a drinking-water quality grade of B with a score of 65.3/100, based on EPA SDWIS compliance data. The county has 10 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 Baldwin County?
Baldwin County has 10 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 Baldwin County?

The top reported causes are MERCURY, ENTEROCOCCUS, ESCHERICHIA COLI (E. COLI). 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 Baldwin County?
EPA's Water Quality Portal records 55,050 measurements from 144 monitoring sites in Baldwin County over the past five years. The most frequently measured characteristic groups are Physical, Inorganics, Minor, Metals, 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 Baldwin County right now?
Baldwin County's primary USGS streamgage on the STYX RIVER has a pipeline snapshot of 580 cubic feet per second — 134% of the long-term mean of 432.05 cfs. This is well above typical — often a signal of recent precipitation or storm runoff. For the latest gauge feed, visit waterdata.usgs.gov.
How does Baldwin County water compare to the Alabama average?
Baldwin County's SDWIS water quality score of 65.3/100 is lower than the Alabama state average of 68.8. The average water quality grade across Alabama is C, based on data from 67 counties with available SDWIS data.
Is tap water safe to drink in Baldwin County?
Based on EPA SDWIS data, Baldwin County has a water quality grade of B (65.3/100). This indicates good to excellent water quality with strong SDWIS compliance.

Why does Baldwin County have so many water violations?
Baldwin County has 10 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 Baldwin County rank for water quality in Alabama?
Baldwin County ranks #45 out of 67 counties in Alabama by SDWIS water quality score (1 = best). With a score of 65.3/100, it falls in the middle 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.
