Well Water in Iron County: What to Test and Why

Groundwater in Iron County contains iron, radon, and arsenic. Iron and radon exceed EPA health standards at moderate to concerning levels, while arsenic is present at lower concentrations.

Iron seeps into groundwater from the rock formations beneath the county. Radon forms naturally from radioactive decay in these same rocks as water moves slowly through cracks and pores underground. Arsenic also occurs naturally in trace amounts within the mineral structure of the local bedrock.

Groundwater in this county is notable for elevated iron, which comes directly from the iron-bearing rocks in the aquifer system. As water sits in contact with these rocks over time, iron dissolves into the water. Elevated iron is common across many wells in this county.

Wells in Iron County commonly contain iron and radon at levels exceeding EPA health standards. Iron at elevated concentrations can affect your blood's ability to carry oxygen and may cause problems with organs over time. Radon is a radioactive gas that enters groundwater naturally and increases the risk of lung cancer with long-term exposure through drinking water.

Iron in county wells causes orange-brown staining on sinks, toilets, and laundry that is difficult to remove. You may notice a metallic or bitter taste in the water. The moderately hard water here can leave scale deposits on pipes and fixtures and may shorten the lifespan of water heaters and dishwashers.

We recommend testing your well water since every well is different and your well may have higher or lower levels than what is common in the county. Testing is the only way to know what is actually in your water so it can be properly treated. A comprehensive metals and minerals panel typically costs $200-400 and would identify iron, radon, and other contaminants. Iron removal systems and radon treatment using aeration can address these concerns.
