Well Water in Henderson County: What to Test and Why

Groundwater in Henderson County contains radon, manganese, and arsenic. Manganese and radon are present at levels that exceed EPA health standards and warrant attention from well owners.

These contaminants come from the rock itself. The crystalline bedrock in this region naturally contains uranium that breaks down into radon gas, and manganese is released into groundwater as water moves through cracks and layers in the rock. Arsenic also occurs naturally in these rock formations. All three travel into well water over time as groundwater sits in contact with the stone.

Groundwater in Henderson County is soft and low in iron, sodium, and sulfate. The crystalline rock here does not contain the limestone or mineral-rich layers that would dissolve into water and add hardness or metals. This soft water character is consistent across most wells in the county.

Wells in Henderson County commonly have manganese and radon at levels above EPA health standards. Manganese can affect the nervous system with long-term exposure, especially in children. Radon is a radioactive gas that increases the risk of lung cancer when breathed in over many years.

The good news is that mineral levels in county wells are generally low, so you probably won't see staining from iron, taste problems from sodium, or the scale buildup that comes with very hard water. Your water should feel and taste pretty normal without those common quality-of-life problems.

We recommend testing your well to find out exactly what you're dealing with, since every well is different and yours could have higher or lower levels than the county average. A comprehensive testing panel that checks for metals and minerals runs between two hundred and four hundred dollars and is the only way to know what treatment your well actually needs. Radon can be removed with aeration systems, and manganese can be filtered out with specialized filters.
