Groundwater in Fisher County contains nitrate, arsenic, iron, and manganese. Several of these contaminants exceed EPA health standards and warrant attention from well owners.
These contaminants come from the local rock and from human activities on the land. The other rock types beneath the county naturally release iron and manganese as water passes through them over time. Nitrate enters groundwater from fertilizers and septic systems, while arsenic occurs naturally in certain rock layers and can also be mobilized by natural processes in the subsurface.
Groundwater in this county is marked by moderate iron content. Iron dissolves from the rock as water moves slowly underground, and this pattern is widespread across wells in the area.
Wells in Fisher County commonly contain arsenic, iron, manganese, and nitrate at levels above EPA health standards. Arsenic exposure raises the risk of cancer and can harm organs over time. Nitrate is especially dangerous for babies and young children, affecting how blood carries oxygen. Iron and manganese at elevated levels can cause nervous system problems with long-term exposure.
Iron in county wells creates reddish-brown staining on sinks, toilets, and laundry. You may notice a metallic or bitter taste in the water. These stains are stubborn and hard to remove from fixtures and clothes.
Every well in your county is different, and yours could have higher or lower levels than what is common here. Testing is the only way to know what is actually in your well so you can treat it properly. We recommend a comprehensive metals and minerals panel, which typically costs $200-400. Treatment options like reverse osmosis or activated carbon filters can address multiple contaminants.

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.
