Groundwater in Jackson County contains sulfate, iron, and manganese--all three contaminants exceed EPA health standards. These levels are concerning enough to warrant your attention and testing.
The Mississippian rock layers beneath Jackson County naturally contain sulfide minerals and iron-bearing compounds. As groundwater moves slowly through cracks and fractures in these dense rocks, water dissolves sulfate and iron over time. This is a natural process driven by the county's geology, not pollution from the surface.
Groundwater in this county is soft but notably sulfur-bearing, characterized by very high sulfate alongside moderate iron levels. Sulfate forms when water contacts sulfide minerals in the bedrock, and the slow movement through rock allows this mineral to concentrate. These characteristics are widespread across wells in Jackson County.
Wells in Jackson County commonly contain iron, manganese, and sulfate at levels that exceed EPA health standards. Iron and manganese can affect how your blood carries oxygen and may harm brain development in children over time. Sulfate at elevated levels can cause digestive issues with long-term exposure.
The mineral content in county wells creates noticeable quality-of-life impacts. Iron leaves orange-brown or rust-colored stains on sinks, toilets, and laundry. Sulfate can give the water a bitter or unpleasant taste and odor. While the water is relatively soft, these staining and taste problems are common complaints from well owners in this area.
We recommend testing your well 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 it can be properly treated. We suggest a comprehensive metals and minerals panel, which typically costs $200-400. Iron removal systems or water softeners combined with filtration 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.
