Groundwater in Hancock County contains sulfate, iron, and manganese at levels that exceed EPA health standards. These contaminant concentrations are serious concerns that require your attention.
The rock beneath Hancock County naturally contains these metals and minerals. As groundwater moves slowly through cracks and tiny spaces in the limestone and shale layers below, sulfate, iron, and manganese dissolve into the water. This is not pollution--it is how the local geology affects your water.
Groundwater in this county is very hard, driven by elevated calcium and magnesium dissolved from the limestone below, and it also carries high sulfate. The slow movement of water through mineral-rich rock layers allows these elements to build up in your water. These characteristics are widespread across wells in this county.
Hancock County well water commonly contains iron, lead, manganese, and sulfate at levels above EPA health standards. Lead exposure harms children's brain development and can affect learning and behavior. Manganese at elevated levels can damage the nervous system over time. Iron and sulfate in drinking water contribute to other health concerns. These contaminants have no color, taste, or smell, so testing is the only way to know if they are in your well.
Wells in this county are extremely hard, and the mineral content creates significant quality-of-life problems. Iron causes orange or rust-colored stains on sinks, toilets, and laundry. High sulfate can give water a bitter or unpleasant taste. The extreme hardness causes thick white, crusty buildup on fixtures and inside pipes, and it can shorten the lifespan of water heaters and dishwashers. Soap will not lather well.
We recommend testing your well with a comprehensive metals and minerals panel, since multiple analytes exceed standards here. Every well is different--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 panel typically costs $200-400. Treatment options like water softeners paired with iron filters can address both hardness and iron contamination.

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.
