Groundwater in Ionia County contains iron, manganese, sulfate, chloride, lead, and nitrate. Several of these contaminants exceed EPA health standards and require attention.
These contaminants come from the bedrock beneath the county and from land-use activities on the surface. Iron and manganese dissolve naturally as groundwater moves slowly through the mixed rock layers underground in low-oxygen conditions. Chloride seeps down from road salt applied to highways and driveways. Lead can enter water from old pipes or plumbing materials. Nitrate comes partly from agricultural fertilizer and septic systems in the area.
Groundwater in this county is notably high in iron. Iron dissolves from minerals in the rock as water passes through slowly underground. This characteristic shows up across many wells in Ionia County.
Wells in Ionia County commonly have chloride, iron, lead, manganese, and nitrate at levels exceeding EPA health standards. Lead damages the brain and kidneys, especially in children, and builds up over years of exposure. Nitrate is dangerous for infants and can cause serious illness. Chloride at elevated levels affects people with high blood pressure. Iron and manganese do not directly pose health risks at the levels found here, but they indicate your well's mineral character.
High iron will stain your sinks, toilets, and laundry orange-brown. Sulfate can give your water a bitter or rotten-egg taste. The mineral buildup from these elements will clog pipes and damage water heaters and dishwashers over time. You may also notice the water tastes metallic or unpleasant.
We recommend testing your well right away through a state-certified lab. Every well is different, and your well 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 water so it can be properly treated. Since multiple contaminants exceed standards, a comprehensive metals and minerals panel typically costs $200-400 and will give you the full picture. Iron removal systems and reverse osmosis can 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.
