Iron, manganese, and arsenic are present in Scott County groundwater. Iron and manganese levels exceed EPA health standards and warrant attention.
The limestone and carbonate rock beneath Scott County naturally contains iron and manganese. As water moves slowly through these rock layers, it dissolves these metals and carries them into wells. Arsenic also occurs naturally in some areas where groundwater contacts certain rock types in the Valley and Ridge.
Groundwater in this county is hard, with elevated calcium and magnesium from the limestone bedrock combined with high iron content. The carbonate rock that fills this region releases these minerals as water percolates down and sits in contact with the stone. These mineral characteristics are widespread across Scott County wells.
Wells in Scott County commonly have iron and manganese at levels above EPA health standards. Iron can cause problems with the blood and organs over time. Manganese affects how the brain and nervous system work, especially in children and infants. Both metals come from the rock and soil around the well.
The high iron in county wells causes noticeable staining on fixtures, laundry, and surfaces where water sits. You may see orange or brown discoloration in sinks and toilets. The water can taste metallic or leave a bitter flavor. Hard water in this county also leaves scale buildup on pipes and appliances, and it shortens the lifespan of water heaters and dishwashers.
We recommend testing your well water to find out exactly what is in it, since every well is different and yours could have higher or lower levels than what is common in the county. Testing is the only way to know what needs treatment. A comprehensive metals and minerals panel costs between two hundred and four hundred dollars and will tell you what you are dealing with. Iron and manganese removal systems like filters or water softeners 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.
