Well Water in Randolph County: What to Test and Why

Groundwater in Randolph County contains arsenic, manganese, pfoa, and pfos at levels that exceed EPA health standards, along with radon. These exceedances mean well owners in this county face real contamination risks that warrant testing and possible treatment.

Arsenic and manganese dissolve naturally from the crystalline rock beneath the county. Pfoa and pfos are human-made chemicals from industrial sites, firefighting foam, and wastewater that have entered groundwater and persist in the environment. Radon comes from the decay of radioactive minerals in the rock itself. These contaminants move downward through soil and reach wells over time.

Groundwater in Randolph County is soft with very low iron, sodium, and sulfate. The crystalline rock here does not release minerals into water the way limestone does, which keeps the water chemically simple and free of hardness. Most wells across the county show this soft-water pattern.

Wells in Randolph County contain arsenic, manganese, radon, and PFOA and PFOS at levels that exceed EPA health standards. Arsenic builds up in your body over time and can cause serious health problems including cancer and organ damage. Manganese at high levels can affect your nervous system and cause problems with movement and learning. Radon is a radioactive gas that increases your risk of lung cancer when you breathe it in through water vapors. PFOA and PFOS are human-made chemicals linked to kidney disease, thyroid problems, and other health effects.

The good news for your minerals is that county wells tend to be soft with low levels of iron and sodium, so you probably won't see staining, scale buildup, or taste problems from those minerals. Your appliances should not wear out faster than normal from hard water.

We recommend a comprehensive panel that tests for all the contaminants that exceed standards in this county, since your well could have higher or lower levels than what is common here. Testing is the only way to know what is actually in your water so you can treat it properly. A comprehensive metals and minerals panel typically costs between two hundred and four hundred dollars. Depending on what testing shows, treatment options like activated carbon filters and radon removal systems can address these concerns.
