Your well water in Holmes County comes from old shale and sandstone rock buried deep underground. These rocks formed millions of years ago from mud and sand. Water fills tiny cracks and spaces between the rock layers. The rock sits at depths that take a long time for water to move through.
Radon, manganese, and iron come straight from the rock itself. These metals and the radioactive radon are locked inside the shale and sandstone. The rock naturally contains these elements. As groundwater slowly moves through the rock over many years, it picks up these contaminants. This is not a problem with your land or septic system—it is what the geology delivers.
Your water is very hard and loaded with minerals. Iron will stain your sinks and laundry orange-brown. Sulfate is high enough to affect taste and smell. You need a water softener and likely an iron filter to make this water work for your home. Testing by a state lab will show exactly what you are dealing with. Treatment is not optional here.
Radon exceeds EPA health standards in Holmes County groundwater. Iron and manganese also exceed health standards. Sulfate and chloride are found at levels that warrant testing. This is a serious situation with multiple contaminants that need your attention right away.
Long-term exposure to radon increases the risk of lung cancer. Manganese at high levels can affect brain development and nervous system health. Iron will stain your sinks, tubs, and laundry orange or brown. The water is extremely hard, leaving white crusty buildup on fixtures and inside pipes. High sulfate can give water a bitter taste or rotten egg smell.
Get your well tested by a state-certified lab immediately. A basic health screen runs fifty to one hundred dollars. A comprehensive mineral and metals panel runs two hundred to four hundred dollars. A whole-house treatment system combining water softening, iron removal, and radon mitigation will address these problems.
