Well Water in McKean County: What to Test and Why

Groundwater in McKean County contains iron, radon, and chloride at levels that exceed EPA health standards. These contaminant levels are concerning enough to warrant testing and attention.

The bedrock beneath McKean County naturally releases radon gas into the water as it slowly moves through fractured rock layers. Iron dissolves from minerals in these same rocks, and chloride enters from road salt applied to county roads during winter.

Groundwater in this county is notable for high iron content. Iron dissolves naturally from the dark rock layers that underlie the area, and these conditions are widespread across wells in McKean County.

Wells in McKean County commonly contain chloride, iron, and radon at levels above EPA health standards. Radon is a radioactive gas that can increase lung cancer risk when it escapes from water into the air you breathe. Chloride at elevated levels can harm people with heart disease or high blood pressure. Iron itself poses no direct health threat, but it indicates your well draws from rock formations where other contaminants may also be present.

Iron in county wells causes orange-brown staining on sinks, toilets, and laundry. You may notice a metallic taste in your water or see rust-colored buildup in pipes and fixtures. The county's mineral levels are not extremely high, so you may not experience severe scaling or shortened appliance lifespan.

We recommend testing your well water with a comprehensive metals and minerals panel, since multiple analytes exceed health standards. 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 panel typically costs two hundred to four hundred dollars, and treatment options like radon mitigation systems or iron filters can address these concerns.
