Groundwater in Wright County contains manganese, iron, arsenic, chloride, lead, nitrite, and uranium. Several of these contaminants exceed EPA health standards and warrant attention from well owners.
These contaminants come from natural sources in the rock beneath the county. Iron and manganese dissolve into groundwater where oxygen levels are low in the aquifer, a common process in buried rock layers. Arsenic, uranium, and lead occur naturally in the rock itself and leach into water over time. Nitrite and chloride can come from both natural sources and human activities like agriculture and road salt use.
Groundwater in Wright County is very hard, driven by elevated calcium and magnesium from the rock below, and contains very high iron. The carbonate and mineral-rich rocks in this area release these elements into water as it moves through the ground. These characteristics are widespread across wells in the county.
Wells in Wright County have been found with arsenic, chloride, iron, lead, manganese, nitrite, and uranium at levels above EPA health standards. Arsenic and uranium can increase cancer risk and damage kidneys and bones over time. Lead harms brain development in children and can affect kidney function and blood pressure in adults. Nitrite prevents blood from carrying oxygen properly, which is especially dangerous for infants. Manganese at high levels can affect the nervous system and learning.
The very hard water in county wells leaves stubborn stains on fixtures and dishes, builds up scale inside pipes and appliances, and shortens the lifespan of water heaters and dishwashers. The high iron content creates reddish staining on sinks, laundry, and fixtures. Hard water makes soap less effective and leaves a film on skin and hair.
We recommend testing your well water with a comprehensive panel, since several contaminants exceed health standards in this county. Your well may have higher or lower levels than what is common here, and testing is the only way to know what you actually need to treat. A comprehensive metals and minerals panel typically costs $200-400 and will show exactly what is in your water. Water softeners and iron filters or aeration systems can help address these concerns based on your specific test results.

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.
