What is the water quality in Newton County, Georgia?
Newton County, Georgia has a drinking-water quality grade of C with a score of 60.1/100, based on EPA SDWIS compliance data. The county has 6 health-based drinking water violations over the past 5 years. Watershed health, monitoring records, and live streamflow are reported separately on this page.
Are there any water violations in Newton County?
Newton County has 6 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 Newton County?
EPA ATTAINS assessments under Clean Water Act §303(d) indicate 64.3% of Newton County's 28 assessed water bodies are classified as impaired (18 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 Newton County?
EPA's Water Quality Portal records 9,724 measurements from 8 monitoring sites in Newton County over the past five years. The most frequently measured characteristic groups are Physical, Nutrient, Inorganics, Major, Non-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 Newton County right now?
Newton County's primary USGS streamgage on the SOUTH RIVER is currently reading 178 cubic feet per second — 29% of the long-term mean of 620.12 cfs. This is well below typical — often a signal of drought stress on source water. For genuine real-time data, visit waterdata.usgs.gov.
How does Newton County water compare to the Georgia average?
