Well Water in Adams County: What to Test and Why

Groundwater in Adams County contains radon, manganese, and arsenic. Manganese and radon exceed EPA health standards and warrant your attention.

These contaminants come from the rock layers beneath the county. As groundwater moves slowly through cracks in the bedrock, it dissolves manganese naturally present in the stone. Radon seeps into the water from radioactive minerals in the rock itself.

Groundwater in this county is very hard, driven by elevated calcium and magnesium from the limestone and shale below. The slow movement of water through these rock layers allows minerals to dissolve and concentrate over time. Very hard water is common across wells in Adams County.

Manganese and radon in wells across Adams County exceed EPA health standards. Manganese can damage children's brain development and affect nervous system function in adults over time. Radon is a radioactive gas that increases the risk of lung cancer with long-term exposure in your home.

Wells in this county are very hard, which leaves white crusty buildup on fixtures and in pipes. Iron staining will appear as orange-brown marks on sinks, toilets, and laundry. The extreme hardness can shorten the lifespan of water heaters and dishwashers. You may also notice a metallic taste or sulfur odor in the water.

We recommend testing your well because every well is different and your water 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. Since multiple contaminants exceed health standards, a comprehensive metals and minerals panel is recommended, which typically costs $200-400. Treatment options like a water softener combined with radon and manganese removal systems can address these concerns.
