Groundwater in Ingham County contains iron, arsenic, and sulfate that well owners should monitor. Arsenic and iron exceed EPA health standards, while sulfate levels are low and not a health concern.
These contaminants come from the bedrock beneath the county. Iron and arsenic occur naturally in the rock layers here and dissolve into groundwater as it moves slowly through them. Sulfate also appears from minerals in the same rock formations.
Groundwater in this county is moderately high in iron. Iron concentrations come from the rock formations that supply water to private wells in this area. Iron at these levels is commonly detected across wells throughout the county.
Wells in Ingham County contain arsenic at levels that exceed EPA health standards. Arsenic builds up in your body over time and can increase the risk of cancer and harm your heart, kidneys, and nervous system. You cannot taste, smell, or see arsenic in water, so testing is the only way to know if it is present.
Iron and sulfate in county wells can create noticeable quality-of-life issues. Iron causes orange or brown staining on sinks, toilets, and laundry. Sulfate can give water a bitter taste or rotten-egg smell. These minerals also build up as scale inside pipes and water heaters over time.
We recommend testing your well water through a 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. A comprehensive metals and minerals panel typically costs $200-400 and can identify all three contaminants at once. Treatment options like reverse osmosis or specialized arsenic-removal systems 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.
