Well owners in Kanabec County need to be aware of radon, manganese, iron, lead, arsenic, and nitrate in their groundwater. Several of these contaminants exceed EPA health standards, making testing and treatment important steps for your household.
These contaminants come from the rock beneath the county. Radon seeps naturally from radioactive elements in the rock. Iron and manganese dissolve into water as it moves through the subsurface. Lead and arsenic can leach from rock layers, while nitrate enters from soil and land use above.
Groundwater in this county is very hard, with elevated calcium and magnesium that come from the bedrock composition. The rock here naturally releases these minerals into the water as it flows through. Very hard water is common across wells throughout the county.
Wells in Kanabec County commonly exceed EPA health standards for lead, arsenic, nitrate, radon, and manganese. Lead damages children's brain development and nervous system function. Arsenic builds up in your body over time and increases cancer risk. Nitrate harms infants and can reduce oxygen in the blood. Radon is a radioactive gas that causes lung cancer when breathed over many years. Manganese at high levels can harm brain development in children.
The very hard water in county wells creates stubborn staining on sinks, toilets, and laundry. You may notice a metallic or unpleasant taste. Mineral buildup creates crusty scale on faucets and shower heads. Hard water shortens the lifespan of water heaters, dishwashers, and washing machines. These quality-of-life issues affect daily living even when health standards are not exceeded.
Every well in this county is different, and your well could have higher or lower levels than what is common here. Testing is the only way to know what is actually in your water so you can treat it properly. We recommend a comprehensive metals and minerals panel, which costs between $200 and $400. Treatment options like whole-house filters, ion exchange softeners, and radon mitigation systems can address these concerns based on your specific 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.
