Groundwater in Fayette County contains iron, manganese, and lead at levels that exceed EPA health standards. These contaminant levels are concerning and require attention from well owners.
Iron and manganese dissolve naturally from the rock layers beneath the county as groundwater sits in low-oxygen conditions deep underground. Lead can enter groundwater from older well components and natural mineral deposits in the bedrock. These metals are part of the county's natural geology, not pollution from surface sources.
Groundwater in Fayette County is very hard, driven by elevated calcium and magnesium from the limestone and dolomite rock below. Iron concentration is very high, and the water also carries moderate sulfate. These mineral characteristics are widespread across wells in this county.
Wells in Fayette County commonly contain iron, lead, and manganese at levels that exceed EPA health standards. Iron at high levels can cause damage to organs over time. Lead is particularly harmful to children's brain development and nervous system function. Manganese exposure in children can affect learning and behavior.
Beyond health concerns, the extremely high iron in county wells causes orange-brown staining on sinks, toilets, and laundry. The very hard water leaves thick white crusty buildup on pipes and fixtures. Hard water this severe can shorten the lifespan of water heaters and dishwashers. You may notice a metallic taste in your water.
We recommend testing your well with a comprehensive metals and minerals panel, since multiple contaminants exceed health standards. Every well is different, and your well may have higher or lower levels than what is common in the county. Testing is the only way to know what is actually in your water so it can be properly treated. Treatment options include water softeners combined with iron removal systems and lead-specific filtration.

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.
