Groundwater in Henry County contains arsenic, PFOA, and PFOS at levels that exceed EPA health standards. These contaminants are present at concentrations serious enough to warrant attention from well owners.
Arsenic occurs naturally in the crystalline rock beneath Henry County and dissolves into groundwater over time. PFOA and PFOS are human-made chemicals that enter groundwater through industrial or commercial activities and contaminated sites. Once these chemicals reach the water table, they persist in the environment and move slowly through the rock layers.
Groundwater in Henry County is soft with moderate iron content. The crystalline rock here naturally releases small amounts of iron as water flows through it, while the rock's composition keeps hardness low. Most wells in this county show similar soft water conditions, though iron levels vary from well to well.
Wells in Henry County contain arsenic, PFOA, and PFOS at levels that exceed EPA health standards. Arsenic exposure can cause skin problems, increase cancer risk, and damage the nervous system and kidneys over time. PFOA and PFOS are chemicals that build up in your body and have been linked to health problems including liver damage, thyroid disease, and immune system issues.
The mineral content in county wells is generally light. Iron is present at moderate levels, which can cause reddish or brownish staining on fixtures, dishes, and laundry. Overall, the water is soft, so you probably won't experience the scale buildup and appliance damage that happens in harder water areas.
Testing is the only way to know what is actually in your well, since every well is different and your water may have higher or lower levels than the county average. We recommend a comprehensive testing panel that checks for metals and chemicals, which typically costs $200 to $400. Treatment options like activated carbon filters or ion exchange systems can remove these contaminants from your water.

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.
