Well Water in Menominee County: What to Test and Why

Groundwater in Menominee County contains radon, iron, and manganese at levels that exceed EPA health standards. These three contaminants together pose health concerns that well owners need to address.

These metals and radon come from the bedrock beneath the county. The rock here is a mix of types that naturally contains iron, manganese, and uranium. As groundwater moves slowly through cracks and spaces in this rock, these materials dissolve into the water. Radon gas seeps into groundwater from tiny amounts of uranium in the stone.

Groundwater in this county is very hard, driven by elevated calcium and magnesium from the rock below. The same rock formations that release iron and manganese also contribute minerals that make water hard. Hard water is common across wells in Menominee County.

Manganese, radon, and iron all exceed EPA health standards in wells across Menominee County. Manganese can harm children's brain development and affect how the body processes certain nutrients. Radon is a radioactive gas that increases lung cancer risk over years of exposure. Iron itself is not a direct health threat, but these three together mean your water needs attention.

Wells in this county are extremely hard, which causes white, crusty scale buildup on pipes and fixtures. This scale can shorten the lifespan of water heaters and dishwashers. You may also see orange or rust-colored staining on sinks and laundry from the iron content. The mineral levels can affect how soap works and leave your dishes spotted.

We recommend testing your well water through a comprehensive metals and minerals panel, which typically costs $200-400. 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. Aeration systems and water softeners combined with iron filters can address multiple concerns.
