Understanding Carroll County’s Water

Drinking Water Quality Overview

EPA SDWIS

Carroll County earns a B grade for drinking water quality, scoring 68.0 out of 100. Over the past five years, EPA SDWIS records 2 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 substantial 50.8% of assessed waterways are impaired (31 of 61 water bodies) across Carroll County's watersheds. The leading impairment causes are fecal coliform and fish bioassessments. 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 2026-05-14T14:15:00.000-04:00) puts CHATTAHOOCHEE RIVER at 1.4k cfs — well below its long-term average at 35% 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. Carroll County has limited coverage with 9 active monitoring sites with 20,908 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 Carroll County

Water Verdict

Carroll County receives a fair water quality assessment with a grade of B and a score of 68.0 out of 100. The water supply meets baseline federal standards, but there may be periods of elevated contaminant levels or infrastructure concerns worth monitoring.

Carroll County has recorded 2 health-based violations, indicating multiple instances where federal contaminant limits or treatment requirements were not met. At 1.9 violations per 100,000 people served, this rate is relatively low compared to many U.S. counties.

Consumer Guidance

Tap water in Carroll County scores well above average for drinking-water safety. Carroll County's drinking-water compliance score is 68.0 out of 100. With 2 recorded health violations, the water supply is generally reliable. The violation rate for Carroll County is 1.9 per 100,000 people served. Households with infants, pregnant individuals, or immunocompromised members may want to use an NSF 53-certified pitcher filter as a low-cost precaution. Fecal Coliform is the leading impairment cause in Carroll County's watershed. There are 9 active water-quality monitoring sites in Carroll County. A pipeline streamflow snapshot from the CHATTAHOOCHEE RIVER gauge is also available on this page.

Regional Context

Carroll County has water quality close to the average county in Georgia. Its water score is within 3.6 points of the state average, meaning its overall water system performance is broadly representative of Georgia as a whole.

Frequently Asked Questions

What is the water quality in Carroll County, Georgia?
Carroll County, Georgia has a drinking-water quality grade of B with a score of 68.0/100, based on EPA SDWIS compliance data. The county has 2 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 Carroll County?
Carroll County has 2 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).

How healthy are the watersheds in Carroll County?
EPA ATTAINS assessments under Clean Water Act §303(d) indicate 50.8% of Carroll County's 61 assessed water bodies are classified as impaired (31 impaired). The top reported causes are FECAL COLIFORM, FISH BIOASSESSMENTS, PCBS IN FISH TISSUE. 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 Carroll County?
EPA's Water Quality Portal records 20,908 measurements from 9 monitoring sites in Carroll 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 Carroll County right now?
Carroll County's primary USGS streamgage on the CHATTAHOOCHEE RIVER has a pipeline snapshot of 1,400 cubic feet per second — 35% of the long-term mean of 3,966.77 cfs. This is well below typical — often a signal of drought stress on source water. For the latest gauge feed, visit waterdata.usgs.gov.
