Groundwater in Buchanan County contains iron, manganese, sulfate, and chloride. These contaminants exceed EPA health standards, making them a concern for well owners in this area.
The rock beneath Buchanan County naturally releases these minerals into groundwater. Water moving slowly through the Pennsylvanian rock layers dissolves iron and manganese from the stone itself. Chloride and sulfate come from deep underground salt deposits that contact the water as it flows through cracks and spaces in the rock.
Groundwater in this county is moderately hard, with elevated iron as the most notable characteristic. Iron concentrates here because water sits in contact with iron-rich rock layers for long periods, allowing the mineral to dissolve into the water supply. These mineral levels are widespread across wells throughout Buchanan County.
Wells in Buchanan County contain chloride, iron, manganese, and sulfate at levels that exceed EPA health standards. Chloride at elevated levels can affect people with high blood pressure or heart conditions. Manganese can harm the nervous system, especially in children and infants whose brains are still developing. Iron and sulfate at these concentrations also pose health concerns for vulnerable people in your household.
The moderate hardness in wells here creates visible and annoying problems. Iron stains laundry, fixtures, and anything it touches with orange or brown marks. You may see white scale buildup on faucets and inside pipes. Hard water reduces how well soap works and leaves spots on dishes and glassware. Over time, mineral deposits can shorten the lifespan of water heaters and dishwashers.
We recommend testing your well water with a comprehensive metals and minerals panel, which costs between two hundred and four hundred dollars. Every well is different, and your water could have higher or lower levels than what is common in the county. Testing is the only way to know exactly what is in your well so you can treat it properly. Iron and manganese removal filters or water softeners can address many of 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.
