Your well water comes from cracks and tiny spaces in old sandstone and shale rock deep underground. These Pennsylvanian rocks formed millions of years ago and hold water where the stone has fractured over time. Water moves slowly through these tight spaces, which means it stays in contact with the rock for a long time.
Radon, manganese, and sulfate come straight from the rock itself. As water sits against the sandstone and shale, these minerals and radioactive elements dissolve into it. The area's history of coal mining has exposed more of these sulfur-rich minerals to water, making the problem worse. Your groundwater has no thick protective layer of gravel or sand to filter out contaminants.
Your water is extremely hard and salty. Iron stains fixtures orange-brown, and the high sulfate gives water a bitter taste and rough feel. You will see white crusty buildup on fixtures and inside pipes.
Radon, manganese, and sulfate exceed EPA health standards in Morgan County wells. Radon is a radioactive gas that comes from natural rock breakdown. Manganese is a metal that dissolves into groundwater. All three of these contaminants need your attention because they appear together in your area's water.
Long-term exposure to manganese can affect your nervous system and brain function. Radon in water releases gas into the air you breathe indoors, which is a lung cancer risk. High sulfate levels cause digestive problems and give water a bitter, salty taste. Your water also has extremely high hardness, iron, and sodium that will stain your sinks and laundry orange-brown and leave thick white scale on pipes and fixtures.
Contact a state-certified lab for a comprehensive mineral and metals panel, which costs around $200 to $400. Ask them to test for all four main concerns: radon, manganese, sulfate, and bacteria. A whole-house treatment system combining radon removal, manganese filtration, and sediment filters can address multiple problems at once.
