Well Water in Clinton County: What to Test and Why

Your well water comes from a rock layer made of shale and sandstone buried deep underground. This Pennsylvanian-age bedrock holds water in its cracks and tiny spaces. The rock is old and has been folded and broken over millions of years.

Iron, manganese, and radon all come from the rock itself. As water sits in the deep cracks with low oxygen, it pulls these metals and gases out of the stone. Sulfate forms when water touches certain minerals in the shale that contain sulfur. These contaminants are not from pollution but from the natural breakdown of the bedrock.

Your water is very hard and mineral-heavy. Iron will stain your sinks and laundry orange-brown. Sulfate and sodium give the water a bitter or salty taste. You need to test your well and talk to a water treatment specialist about filters or softeners to handle these mineral levels.

Your well water in Clinton County exceeds EPA health standards for radon, manganese, and iron. These contaminants are found at levels that require immediate attention. Radon is a radioactive gas that dissolves into groundwater and poses the highest health risk to your family.

Long-term exposure to radon increases lung cancer risk, especially for children and people who spend time at home. High manganese can affect brain development and cause nervous system problems. Iron causes orange-brown staining on sinks, toilets, and laundry. The water is extremely hard, leaving thick white scale on pipes and fixtures.

Get your well tested by a state-certified lab right away—a comprehensive metals and radon panel costs $200–400. Ask the lab to test for radon, manganese, iron, and uranium. A whole-house radon removal system combined with iron and manganese filtration will address your main concerns.
