Groundwater in Coweta County contains radon, PFOA, and PFOS, all three at levels that exceed EPA health standards. These are serious contaminants that require your attention.
Radon seeps into groundwater naturally from radioactive elements in the crystalline rock beneath this county. PFOA and PFOS are human-made chemicals that enter groundwater through industrial discharge, manufacturing sites, and contaminated materials in the soil. These chemicals persist in the environment and move into wells over time.
Groundwater in this county is soft, with only moderate iron present. The crystalline bedrock here does not dissolve easily, so it contributes few minerals to the water. Iron at moderate levels appears in wells across this county because it comes from small amounts of iron-bearing minerals in the rock as groundwater slowly moves through cracks and fractures.
Coweta County wells contain PFOA, PFOS, and radon at levels that exceed EPA health standards. PFOA and PFOS are human-made chemicals that can build up in your body over time and affect your liver, thyroid, and immune system. Radon is a radioactive gas that enters groundwater naturally and increases the risk of lung cancer when you breathe it in or drink it over many years.
Coweta County's groundwater is soft, so you won't see heavy staining or scale buildup from minerals. Iron levels in the county are moderate but generally low enough that most wells don't cause the orange staining or metallic taste that comes with higher iron. Your appliances and plumbing should work normally without the wear that extremely hard water causes.
Since Coweta County has multiple contaminants above EPA standards, we recommend a comprehensive water test to know what is actually in your well. Your well could have much higher or lower levels than what is common here--testing is the only way to find out. A comprehensive panel runs $200-400 and checks for metals, minerals, and chemicals. Depending on your results, treatment options like activated carbon filters or radon ventilation systems can help.

MCL = Maximum Contaminant Level (EPA limit for public water; used as benchmark for private wells). Distribution shows % of sampled wells in each concentration band. Methodology.
* Microbial contaminants (E. coli, coliform) reflect only samples from the last 10 years.
