Groundwater in Chippewa County contains iron, manganese, and nitrite at levels that exceed EPA health standards. These contaminants warrant attention from well owners, though they are not uncommon in this region.
Iron and manganese dissolve naturally into groundwater as water moves through the mixed rock layers beneath the county. Nitrite enters from fertilizer and septic systems in agricultural and residential areas. The local geology is the primary source for the metals, while land use drives nitrite contamination.
Groundwater in this county is moderately hard, primarily from calcium and magnesium dissolved from the rock below. Iron and manganese concentrations contribute to the water's character, though iron levels measured in wells here are low overall. Moderately hard water with iron and manganese is common across many wells in the county.
Wells in Chippewa County commonly have iron, manganese, nitrate, and nitrite at levels above EPA health standards. Iron and manganese can harm your organs and nervous system if you drink contaminated water over time. Nitrate and nitrite are especially dangerous for babies and young children, as they can interfere with how the body carries oxygen in the blood.
The moderate hardness in county wells means you may see some staining on fixtures and laundry from iron and manganese. The water might have a metallic taste or slight odor. You probably won't experience severe scaling in your pipes or major appliance problems, since the hardness level here is not extreme.
Testing is the only way to know what is actually in your well, since every well is different and your water could have higher or lower levels than what is common in the county. We recommend a comprehensive metals and minerals panel, which typically costs between $200 and $400. Treatment options like iron and manganese removal systems can help address these concerns once you know 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.
