Groundwater in Floyd County contains manganese, iron, and arsenic. Iron and manganese exceed EPA health standards at moderate levels in this county's wells.
The carbonate limestone rock beneath Floyd County naturally releases iron and manganese as groundwater flows through it over time. Arsenic also occurs naturally in these rock layers. These contaminants come from the bedrock itself, not from pollution or land use.
Groundwater in this county is soft, with iron as the main mineral character. The acidic water moving through carbonate rock dissolves iron-bearing minerals, releasing iron into the water supply. Iron is moderately present across wells in this county.
Iron and manganese show up at concerning levels in Floyd County wells. Both can affect your health over time. Manganese exposure can harm brain and nervous system development, especially in children and babies. Iron at elevated levels can cause problems for people with certain health conditions.
The water in county wells tends to be soft, which is good news for scale buildup and appliance lifespan. You probably won't see much staining or mineral deposits around your faucets or fixtures. The water should taste relatively clean without mineral flavors.
Every well is different, and your water could have higher or lower levels than what's common in the county. Testing is the only way to know what's actually in your well so you can treat it properly. We recommend a comprehensive metals and minerals panel to check all the contaminants of concern. Iron can be removed through filtration systems, and manganese requires specific treatment approaches.

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.
