Well Water in Fluvanna County: What to Test and Why

Groundwater in Fluvanna County contains radon, nitrate, and manganese that exceed EPA health standards. These contaminants are present at levels serious enough that well owners need to test and treat their water.

Radon comes from natural radioactive decay in the bedrock beneath the county. Nitrate and nitrite enter groundwater from fertilizers and septic systems in areas with sandy or permeable soil that lets contaminants seep down to the water table. Manganese occurs naturally in the local rock layers and dissolves into the water as it moves underground.

Groundwater in this county is soft and low in minerals overall, with very little iron or sulfate present. The water composition reflects the local underground rock, which does not contribute high levels of calcium, magnesium, or iron the way harder-rock areas do. Most wells here share this soft-water character, though radon, nitrate, and manganese levels vary from well to well.

Wells in Fluvanna County have been found with manganese, nitrate, nitrite, and radon at levels that exceed EPA health standards. Manganese can affect the nervous system, especially in children, and cause learning and behavior problems with long-term exposure. Nitrate and nitrite are dangerous for infants and can prevent their blood from carrying oxygen properly. Radon is a radioactive gas that increases lung cancer risk when breathed in over time.

The good news is that the minerals in county well water are at low levels, so you probably won't see staining, scale buildup, or strange tastes or smells from iron, sodium, or hardness. Your water should feel and look normal in everyday use.

We recommend that you test your well water for the contaminants found in this county. Every well is different, and your water could have higher or lower levels than what is typical here. Testing is the only way to know what is actually in your well so you can treat it correctly. A comprehensive panel that checks for metals, bacteria, and chemicals runs between $200 and $400. Treatment options like activated carbon filters or aeration can address many of these concerns, depending on what testing shows.
