Well Water in Goochland County: What to Test and Why

Groundwater in Goochland County contains manganese, radon, and iron at levels that exceed EPA health standards. Well owners need to be aware that these contaminants are present at concerning concentrations in this area.

These metals come from the rock layers beneath the county. The Early Mesozoic basin rocks that hold the groundwater naturally contain iron and manganese. Radon is a radioactive gas that forms when uranium in the rock breaks down over time, and it seeps into the water from the surrounding stone.

Groundwater in this county is soft but moderately high in iron. Iron concentrates in the water because it dissolves from the basin rocks as groundwater moves slowly through them. These characteristics are widespread across wells throughout Goochland County.

Wells in Goochland County have been found to exceed EPA health standards for iron, manganese, and radon. Iron and manganese at high levels can affect your organs over time with long-term exposure. Radon is a radioactive gas that comes from underground and can damage your lungs, especially with years of breathing it in your home.

The iron and manganese in county wells commonly cause orange or brown staining on sinks, toilets, and laundry. You might notice a metallic taste in your water or see colored particles when you turn on a tap. Since the county's water is relatively soft overall, scale buildup is not a major concern, but the staining from iron and manganese can be frustrating to clean.

We recommend having your well tested as soon as possible, since every well is different and yours could have higher or lower levels than what is common in the county. A comprehensive test for metals and minerals costs between $200 and $400 and is the only way to know what is actually in your water so you can treat it properly. Iron and manganese can be removed with filters or oxidation systems, and radon can be addressed with ventilation or aeration equipment.
