Well Water in Carbon County: What to Test and Why

Your well draws water from old limestone bedrock full of cracks and fractures. This rock sits deep underground and holds water in the spaces between pieces. The same type of limestone stretches across much of this region and neighboring counties too.

Three contaminants stand out here: radon, arsenic, and sulfate. Radon is a radioactive gas that forms naturally inside the limestone and seeps into groundwater through the rock's many cracks. Arsenic sits naturally in the rock itself. Sulfate appears when rainwater dissolves minerals as it moves slowly through the fractured bedrock on its way down to the water table.

Your water is extremely hard and loaded with minerals. The high sodium and sulfate levels—along with iron—mean you'll see white crusty buildup on faucets and pipes, orange stains in sinks and toilets, and a salty taste in the water. These mineral levels affect everything from laundry to appliances and make treatment a practical consideration for most households here.

Arsenic, radon, and sulfate all exceed EPA health standards in Carbon County wells. This combination of concerns makes testing important for your family's health. The sulfate level here is especially high and exceeds what the EPA recommends for drinking water.

Long-term exposure to arsenic increases cancer risk and can harm your kidneys and nervous system. Radon exposure over years raises your risk of lung cancer. The extremely high sulfate and sodium in your water will cause diarrhea and may be problematic if anyone in your household has heart or kidney disease. You'll also notice white crusty buildup on pipes and fixtures, rust-colored stains on sinks and laundry from the iron, and a bitter or salty taste.

Get your well tested by a state-certified lab right away with a comprehensive metals and minerals panel, which typically costs $200–400. A basic bacteria and nitrate screen runs $50–100 if you want to start there. A whole-house treatment system combining arsenic removal and radon aeration can address your main health risks.
