Iron, arsenic, and chloride are present in Vernon County groundwater. Iron exceeds EPA health standards at moderate levels, while arsenic and chloride are detected but at lower concern levels.
These contaminants come from the deep rock layers beneath the county. Iron dissolves naturally as water moves slowly through the rock over many years. Arsenic and chloride occur naturally in the minerals that make up these old rock formations.
Groundwater in this county is very hard, driven by elevated calcium and magnesium from the bedrock. The slow movement of water through limestone and other rock layers allows these minerals to dissolve and accumulate in the water. Very hard water is widespread across wells in Vernon County.
Iron exceeds EPA health standards in wells across Vernon County. Drinking water with elevated iron can cause problems in your body over time, including effects on your organs and how your body processes nutrients. Children may be more sensitive to these effects than adults. Testing your well is the only way to know if iron is a concern for your family.
Vernon County has very hard water, which means mineral buildup happens fast. You will see white or chalky scale on faucets, showerheads, and inside pipes. Hard water makes soap less effective and can leave spots on dishes and glassware. Very hard water also shortens the lifespan of water heaters, dishwashers, and washing machines because scale clogs them up inside.
We recommend testing your well water since every well is different and your water may have higher or lower levels than what is common in the county. A comprehensive metals and minerals panel costs between two hundred and four hundred dollars and will show exactly what is in your water. Iron removal systems and water softeners can treat these problems once you know what you are dealing with.

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.
Data shows potential risk — a certified test confirms whether your water is affected.
