Well Water in Huntingdon County: What to Test and Why

Huntingdon County well water contains iron, radon, and sulfate at levels that exceed EPA health standards. These contaminants are present at concentrations serious enough to require testing and treatment.

The Valley and Ridge rock layers beneath this county contain iron-bearing minerals that dissolve into groundwater as water moves slowly through cracks and spaces in the bedrock. Radon forms naturally from radioactive elements trapped in these same rocks, and sulfate enters the water from minerals within the stone layers.

Groundwater in this county is moderately hard, with elevated iron as the most noticeable mineral character. Iron comes from the shale and other dark rock layers that make up the local aquifer, and these iron levels show up consistently across wells throughout the county. Radon and sulfate are also common findings in wells here.

Wells in Huntingdon County commonly contain iron, lead, PFOA, PFOS, radon, and sulfate at levels exceeding EPA health standards. Iron can cause digestive problems and affect the brain and organs over time. Lead damages brain development in children and harms the nervous system in adults. PFOA and PFOS are human-made chemicals that can affect immune function and increase disease risk with long-term exposure. Radon is a radioactive gas that increases lung cancer risk when breathed in from water vapor during showers and everyday use. Sulfate at high levels can cause stomach problems and digestive issues.

Wells in this county produce moderately hard water that leaves white crusty buildup on pipes and fixtures. The elevated iron causes orange-brown staining on sinks, toilets, and laundry. Hard water can shorten the lifespan of water heaters and dishwashers over time. You may notice unpleasant tastes or odors in your water.

We recommend testing your well because multiple contaminants exceed health standards. 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 well so it can be properly treated. A comprehensive metals and radon panel typically costs $200-400. Treatment options like aeration systems and activated carbon filters can address these concerns.
