Groundwater in Chippewa County contains arsenic, chloride, and E. coli, but none exceed EPA health standards, meaning contaminant levels here are low. Well owners should be aware of these substances, though they are not a health concern at the concentrations detected in this county.
The rock and soil in this area naturally release small amounts of arsenic into groundwater. Chloride enters from road salt and everyday sources like septic systems, and E. coli bacteria can seep in from surface contamination near wells. The low levels here reflect the county's mixed rock types, which do not strongly concentrate these contaminants the way other geological settings can.
Groundwater in this county is soft, with low sodium and sulfate levels. The soft water comes from rock that does not dissolve minerals like calcium and magnesium easily. Most wells here produce water with similar gentle mineral content.
Wells in Chippewa County do not show analytes exceeding EPA health standards at the county level. However, arsenic, chloride, and E. coli appear in some wells across the area. Arsenic can cause skin changes and increase cancer risk over many years. Chloride at high levels can harm people on low-sodium diets. E. coli bacteria indicate contamination and can cause serious stomach illness.
The mineral content in county wells is quite low and soft. This means you won't deal with crusty buildup on faucets, showerheads, or inside pipes. Your appliances like water heaters should not wear out faster from mineral scale. The water should feel pleasant to use and won't create stubborn stains on laundry or sinks.
Testing is the only way to know what is actually in your specific well, since every well is different and your water could be higher or lower than what is common in the county. We recommend a basic screening test for bacteria and nitrate, which costs around fifty to one hundred dollars. If you want more information about metals and minerals, a comprehensive panel runs two hundred to four hundred dollars. Treatment options like chlorine disinfection or activated carbon filters can address contaminants that show up in your 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.
