Radon, manganese, and nitrate are the contaminants well owners in Appomattox County should know about. These three exceed EPA health standards in this area's groundwater, making them worth monitoring.
Radon seeps into groundwater from the rock below as naturally radioactive minerals decay over time. Manganese comes from the Early Mesozoic basin rock that underlies the county--a rock type that releases manganese into water. Nitrate usually enters from fertilizers and septic systems on the land surface and works its way down through soil into wells.
Groundwater in this county is soft, with low levels of calcium and magnesium from the basin rock. The water carries very little sodium and sulfate. These characteristics are fairly consistent across wells in the county because the underlying rock type is similar throughout the area.
Wells in Appomattox County show three contaminants that exceed EPA health standards: manganese, nitrate, and radon. Manganese at high levels can affect the nervous system and cause problems with movement and learning, especially in children. Nitrate is a concern for infants and can interfere with how blood carries oxygen. Radon is a radioactive gas that increases the risk of lung cancer when inhaled over time.
The good news is that the county's water is naturally soft with very low sodium and sulfate levels. This means wells here are unlikely to cause staining, scale buildup on fixtures, or the taste and odor problems that plague harder water areas. Your appliances should not wear out faster from mineral damage.
We recommend testing your well water because every well is different, and yours could have higher or lower levels than what is common in the county. A comprehensive panel that checks for metals, minerals, bacteria, and chemicals costs between $200 and $400 and is the only way to know what is actually in your water. Once you know what you are dealing with, you can decide on treatment options like aeration for radon or filtration for manganese and nitrate.
