Groundwater in Clare County contains iron, manganese, and sulfate that well owners should monitor. These contaminants exceed EPA health standards, making testing and treatment important for your household.
The rock layers beneath Clare County naturally release iron and manganese as groundwater moves slowly through them over time. Sulfate also dissolves from minerals in these rock formations. These are not pollution problems from surface activities but rather minerals that come directly from the bedrock itself.
Groundwater in this county is high in iron, which drives its character along with measurable sulfate. Iron dissolves naturally from the rock as water sits in contact with it underground. These characteristics are common across wells throughout the county.
Wells in Clare County commonly contain chloride, iron, manganese, and sulfate at levels above EPA health standards. Chloride at elevated levels can affect kidney function and blood pressure over time. Iron and manganese are metals that dissolve from rocks underground and can damage your organs with long-term exposure. Sulfate in drinking water can cause digestive problems.
High iron in county wells leaves orange or brown stains on sinks, toilets, and laundry. Manganese can darken stains and create buildup inside pipes and appliances. Over time, these mineral deposits can shorten the lifespan of water heaters and dishwashers. The water may also taste metallic or have an unpleasant odor.
We recommend testing your well with a comprehensive metals and minerals panel because every well is different and your water may have higher or lower levels than what is common in the county. Testing is the only way to know what is actually in your well so you can treat it properly. A comprehensive panel typically costs $200-400. Iron removal systems and water softeners can help address these concerns.

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.
