Well Water in Bedford County: What to Test and Why

Iron, radon, and sulfate are present in Bedford County's groundwater at levels that exceed EPA health standards. These contaminants are a serious concern that demands testing and treatment.

The Mississippian rock layers beneath this county contain iron-rich minerals and natural uranium. As groundwater moves slowly through cracks in these rocks, it dissolves iron and picks up radon gas released from radioactive decay in the stone. Sulfate enters the water from minerals within the same bedrock.

Groundwater in this county is hard, driven by elevated calcium and magnesium from the rock below. The slow movement of water through these mineral-bearing rocks allows iron and hardness to build up. These characteristics show up across wells throughout the county.

Wells in Bedford County commonly contain iron, radon, and sulfate at levels above EPA health standards. Radon is a radioactive gas that can increase lung cancer risk when breathed in from shower steam and other water uses over time. Iron and sulfate themselves are not health risks at the levels found here, but radon exposure is a serious concern that deserves attention.

Wells in this county produce very hard water along with high iron, which creates visible problems in your home. You will see orange-brown stains on sinks, toilets, and laundry. Hard water leaves white crusty buildup on pipes and fixtures, and over time can shorten the lifespan of water heaters and dishwashers.

We recommend testing your well through a certified lab because every well is different and yours may have higher or lower levels than what is common in the county. A comprehensive metals and radon panel typically costs between $200 and $400 and is the only way to know what is actually in your water so it can be properly treated. Aeration systems combined with iron filters and radon removal can address these concerns.
