Groundwater in Fulton County contains manganese, radon, PFOS, and PFOA at levels exceeding EPA health standards. These contaminant levels are concerning and warrant your attention.
Manganese and radon come naturally from the crystalline rock beneath the county. PFOS and PFOA are human-made chemicals that enter groundwater from industrial sites, landfills, and other sources and persist in the environment. The rock's fractures allow both natural minerals and contamination to reach well water.
Groundwater in this county is soft with low iron and low minerals overall. The hard crystalline rock here breaks down slowly, releasing few dissolved minerals into the water. Most wells in Fulton County show this soft-water pattern.
Fulton County wells contain manganese, PFOA, PFOS, and radon at levels that exceed EPA health standards. Manganese can affect your nervous system and brain development, especially in children. PFOA and PFOS are human-made chemicals that can harm your liver, immune system, and thyroid over time. Radon is a radioactive gas that increases lung cancer risk when you breathe it in.
The mineral content in county wells is soft and low in iron, sodium, and sulfate. This means you should not experience staining on fixtures or clothes, buildup of scale in pipes, or unpleasant tastes and odors. Your water heater and dishwasher should have a normal lifespan.
Testing your well is the only way to know what is actually in your water, since every well is different and your levels could be higher or lower than what is common in the county. We recommend a comprehensive panel that checks for metals, minerals, and chemicals, which typically costs $200-400. Depending on your results, treatment options like activated carbon filters or radon mitigation systems can address what you find.

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.
