Well Water in Barron County: What to Test and Why

Groundwater in Barron County contains arsenic, iron, and radon, and all three are present at levels that exceed EPA health standards. These contaminants deserve attention from well owners in this area.

These metals and radon come from the rock itself. The mixed rock types underlying the county naturally contain these elements, and as groundwater moves through the rock over time, it dissolves them and carries them into wells.

Groundwater in this county is soft, with moderate iron being the main aesthetic characteristic. The soft water reflects a lack of calcium and magnesium in the local rocks, while iron concentrates in the water as it passes through iron-bearing layers. Moderate iron is common across wells in this county.

Arsenic, iron, and radon are found at levels exceeding EPA health standards in wells across Barron County. Arsenic can damage organs and increase cancer risk with long-term exposure. Radon is a radioactive gas that builds up in lungs over time and raises the chance of lung cancer. Iron itself does not pose a direct health threat at the levels found here.

The iron in county well water can leave rust-colored stains on fixtures, laundry, and dishes. You may also notice a metallic or bitter taste. The good news is that wells in this county are soft, so you won't experience the scale buildup and appliance damage that comes with hard water.

We recommend testing your well to find out what is actually in your water, since every well is different and yours may have higher or lower levels than what is common in the county. A comprehensive metals and radon panel typically costs between $200 and $400. Testing is the only way to know what treatment you need, whether that is an arsenic filter, iron removal system, or radon reduction approach.
