Well Water in Morrison County: What to Test and Why

Iron stands out as the main contaminant in Morrison County groundwater that exceeds EPA health standards. The iron level is at a moderate concentration, making it the primary concern for well owners in this area.

Iron comes from the bedrock and soil layers beneath the county. The underlying rocks naturally contain iron minerals that dissolve into groundwater as water moves through them over time. This is a common problem across much of central Minnesota where similar rock types are found.

Groundwater in this county is hard, driven by elevated calcium and magnesium that come from the rock layers below. These minerals accumulate as water percolates down through the soil and bedrock, dissolving them slowly along the way. Hard water and moderate iron levels are found in most wells throughout Morrison County.

Wells in Morrison County commonly have elevated iron levels that exceed EPA health standards. Iron in drinking water can cause problems in your body over time, affecting how your organs work and how your body uses oxygen. Children and people with certain health conditions may be more at risk from these elevated levels.

The hard water in county wells leaves visible stains on sinks, tubs, and laundry. You might see orange or brown discoloration from iron buildup. Hard water also creates scale inside pipes and can shorten the lifespan of water heaters and dishwashers. You may notice a metallic taste in the water.

We recommend testing your well to find out what is actually in your water, since every well in the county is different and yours could have higher or lower levels than what is common here. Testing is the only way to know if treatment is needed for your family. A comprehensive metals and minerals panel typically costs between $200 and $400 and will show you exactly what you are dealing with. Iron can be removed with filtration or oxidation systems.
