Well Water in Dodge County: What to Test and Why

Groundwater in Dodge County contains iron, sulfate, and arsenic. Iron and sulfate exceed EPA health standards, which makes them concerns that deserve attention.

The deep rock layers beneath this county naturally contain iron and sulfate minerals. As groundwater moves slowly through these rock formations over many years, it dissolves these minerals and carries them into wells. Arsenic also occurs naturally in these deep layers.

Groundwater in Dodge County is very hard, driven by elevated calcium and magnesium from the rock below. These minerals dissolve into water as it passes through the limestone and other rock layers over time. Very hard water is widespread across wells throughout the county.

Iron and sulfate in wells throughout this county exceed EPA health standards. Iron at elevated levels can cause stomach problems and affect how your body absorbs nutrients. Sulfate at high levels can cause digestive issues, especially in infants and people with certain health conditions.

The very hard water in this county creates visible problems around your home. You will see rust-colored stains on sinks, toilets, and laundry. Hard water leaves chalky white scale inside pipes and on fixtures. This very hard water can shorten the lifespan of water heaters and dishwashers. Soap becomes less effective, making cleaning harder.

We recommend testing your well water, since 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. A comprehensive metals and minerals panel typically costs between $200 and $400. Water softeners can reduce hardness, and iron removal systems can address elevated iron levels.
