Why This Happens Here

Your well taps into old rock layers made of sandstone and shale that formed millions of years ago. These rocks have cracks and tiny spaces where water sits and moves very slowly. The rock itself holds minerals and gases that dissolve into the water over time.

Manganese, radon, and sulfate show up because they come straight from the rock. Iron sulfide minerals in the shale break down when water touches them, releasing both iron and sulfate. Radon is a radioactive gas that seeps out of the rock naturally. Chloride also appears because salty water moves through certain rock layers. The slow movement of water through these tight spaces gives minerals extra time to dissolve.

Your water is extremely hard with high amounts of sodium and sulfate. This means you will see thick white or gray crusty buildup on pipes and fixtures. Stains from iron will appear orange-brown on sinks and laundry. The salty taste and mineral content make this water difficult to use without treatment, and the high sodium makes it unsuitable for people on salt-restricted diets.

What This Means for You

Radon, manganese, and sulfate in Athens County wells exceed EPA health standards. Radon is a radioactive gas that comes from the bedrock. Manganese is a metal trapped in the rock layers. Your well water shows all three at levels that warrant action.

Breathing radon released from shower steam increases lung cancer risk over many years. Manganese exposure can affect how your brain and nervous system work in children and adults. You'll also notice orange-brown stains from iron on sinks and laundry, a rotten-egg smell from sulfate, and thick white scale buildup from extremely high hardness and sodium.

Get your well tested by a state-certified lab for a comprehensive mineral and metals panel, which costs $200–400. A basic bacteria and nitrate screen runs $50–100. Install a treatment system that removes radon, manganese, and hardness to address the main health and quality-of-life concerns.
