Groundwater in Whitfield County contains PFOA and PFOS, which are human-made chemicals that exceed EPA health standards. These contaminants are present at levels the EPA considers concerning for drinking water.
PFOA and PFOS enter groundwater through industrial and commercial activities, firefighting foam use, and contaminated sites. These chemicals don't break down easily in soil and can move through the limestone and rock layers to reach well water, especially where the rock is fractured or where past industrial use was common.
Groundwater in this county is moderately hard, driven by calcium and magnesium released as water moves through the limestone bedrock. The carbonate rocks dissolve slowly in acidic groundwater, releasing these minerals into the water supply. Moderate hardness is a widespread characteristic across wells in this county due to the limestone aquifer present throughout the Valley and Ridge.
Wells in Whitfield County have been found to contain PFOA and PFOS at levels exceeding EPA health standards. These human-made chemicals can accumulate in your body over time and have been linked to serious health effects including kidney and liver damage, thyroid problems, and immune system weakening. Exposure through drinking water is a real concern for families in this area.
Whitfield County wells are moderately hard, which means you might see white scale buildup on faucets and fixtures, spotting on dishes and glassware, and reduced effectiveness of soap and shampoo. Hard water can also shorten the lifespan of water heaters and dishwashers by several years. Your sodium and sulfate levels are low, so taste and odor issues are not a major concern in county wells.
We recommend a comprehensive water quality test to find out what is actually in your well, since every well is different and yours could have higher or lower levels than what is common countywide. Testing is the only way to know if treatment is needed for your family. A comprehensive panel typically costs between two hundred and four hundred dollars. Treatment options like activated carbon filters or ion exchange systems can address PFOA and PFOS contamination.

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.
