Iron is present in McDuffie County's groundwater, along with chloride and fluoride. Iron levels are high enough to exceed EPA health standards, which is a concern for well owners in this area.
The rock beneath McDuffie County contains iron minerals that break down and dissolve into groundwater over time. This is natural wear on the crystalline rock that makes up the Piedmont region, and it happens slowly as water moves through fractures and spaces in the stone.
Groundwater in this county is high in iron, which comes directly from the breakdown of iron-rich minerals in the crystalline bedrock. The water is soft overall, meaning it does not have elevated calcium and magnesium the way water in limestone regions does. High iron is a common finding across wells throughout McDuffie County.
Wells in McDuffie County commonly have iron at levels that exceed EPA health standards. High iron in drinking water can cause problems with your blood's ability to carry oxygen and may affect your organs over time. Children and pregnant women are at greater risk from exposure to elevated iron.
Iron at high levels in county well water leaves rust-colored stains on sinks, toilets, and laundry. It can give water a metallic taste and create an unpleasant odor. These stains are hard to remove and build up over time on your fixtures and clothes.
We recommend testing your well water as soon as possible. Every well is different, and your water could have more or less iron than what is common here. Testing is the only way to know exactly what is in your well so you can treat it properly. A comprehensive panel costs between $200 and $400 and will show you what you are dealing with. Iron can be removed with filters or water softeners designed for iron reduction.

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.
