Well Water in Clinton County: What to Test and Why

Groundwater in Clinton County contains manganese, radon, iron, and sulfate at levels that exceed EPA health standards. These are serious concerns that require testing and treatment to protect your family's health.

The rock beneath Clinton County naturally releases these contaminants into groundwater. Manganese and iron dissolve from the coal-bearing stone layers as water sits in contact with them over time. Radon seeps from natural radioactive elements trapped in the rock. Sulfate forms when water touches minerals containing sulfur in these same rock layers.

Groundwater in Clinton County is soft, but it carries elevated iron that gives it a notable mineral character. Iron dissolves directly from the bedrock as water moves slowly through fractured layers. This characteristic is widespread across wells in the county, though levels vary from well to well.

Wells in Clinton County commonly exceed EPA health standards for iron, manganese, radon, and sulfate. Radon is a radioactive gas that increases lung cancer risk with long-term exposure through inhalation and ingestion. Manganese at elevated levels can affect brain development and function, especially in children. Iron and sulfate at high concentrations can cause digestive problems and other health concerns over time.

Wells in this county tend to have moderate iron levels that cause orange-brown staining on sinks, toilets, and laundry. While the county's water is relatively soft, which limits scale buildup in pipes, iron still creates visible discoloration that is difficult to remove. You may notice a metallic or unpleasant taste in your water from these mineral levels.

We recommend testing your well water with a comprehensive metals and radon panel, since multiple contaminants exceed health standards in county wells. Every well is different, and your water may have higher or lower levels than what is common here. Testing is the only way to know what is actually in your well so it can be properly treated. A comprehensive panel typically costs $200-400, and treatment options like aeration systems and specialized filtration can address these concerns.
