Well Water in Augusta County: What to Test and Why

Radon, arsenic, and chloride are present in Augusta County groundwater that well owners should know about. Radon exceeds EPA health standards in this county, while arsenic and chloride are detected but at levels below those thresholds.

Radon enters groundwater naturally from radioactive minerals in the Valley and Ridge rock beneath the county. Arsenic also comes from the bedrock itself as water passes through certain rock layers. Chloride can come from the rock or from road salt and other surface sources that seep downward.

Groundwater in this county is very hard, driven by calcium and magnesium from the limestone and other carbonate-rich rocks in the Valley and Ridge. As water moves slowly through these rocks, it dissolves minerals that build up in the water. Very hard water is common across wells throughout Augusta County.

Radon is the main health concern found above EPA standards in wells across Augusta County. Radon is a radioactive gas that comes from natural decay in the bedrock and can accumulate in groundwater. Long-term exposure through drinking water increases the risk of stomach cancer. Arsenic and chloride also appear in county groundwater and warrant attention, though they are less commonly elevated to the same degree as radon.

Wells in this county have very hard water, which creates noticeable quality-of-life impacts. Hard water leaves white mineral scale on faucets, shower heads, and inside pipes. It reduces how well soap works for cleaning and can make your skin feel dry. The extreme hardness can shorten the lifespan of water heaters and dishwashers by causing buildup inside these appliances.

We recommend testing your well, since every well is different and yours may have higher or lower levels than what is common here. Testing is the only way to know exactly what is in your water so it can be properly treated if needed. A comprehensive panel checking for metals and radioactive elements typically costs between two hundred and four hundred dollars. Radon can be reduced through aeration or ventilation systems, and other contaminants respond to different treatment approaches.
