Well Water in Putnam County: What to Test and Why

Groundwater in Putnam County contains radon, chloride, and manganese. These contaminants exceed EPA health standards and require your attention.

The limestone and carbonate rock below this county naturally releases radon into the groundwater as radioactive elements in the stone break down over time. Chloride enters the water from road salt and other sources above ground that seep down into the aquifer. Manganese dissolves from the minerals in the limestone as groundwater moves slowly through the rock.

Groundwater in this county is moderately hard, with moderate iron content and moderate sodium from the carbonate and iron-bearing minerals in the bedrock. Water dissolves these minerals as it passes through limestone and iron-rich rock layers underground. Most wells across the county show these mineral characteristics to varying degrees.

Putnam County wells commonly exceed EPA health standards for chloride, iron, manganese, and radon. Chloride at elevated levels can harm people with high blood pressure or heart conditions. Iron and manganese can affect the nervous system, especially in children and developing fetuses. Radon is a radioactive gas that increases the risk of lung cancer over time.

Iron in county wells leaves reddish-brown staining on fixtures, laundry, and sinks. Manganese can cause brown or black discoloration. You may notice a metallic or bitter taste in your water. The moderate hardness can leave scale buildup on pipes and inside water heaters and dishwashers, shortening their lifespan.

Testing your well is the only way to know what is actually in your water, since every well is different and yours could have higher or lower levels than what is common here. We recommend a comprehensive metals and minerals panel that tests for all these concerns, which typically costs between $200 and $400. Treatment options like water softeners, filtration systems, and radon mitigation can address these issues once you know your results.
