Well Water in Jackson County: What to Test and Why

Manganese, iron, and sulfate are present in Jackson County's groundwater and well owners should be aware of them. These contaminant levels are concerning enough that they exceed EPA health standards.

The Mississippian bedrock beneath Jackson County contains iron and manganese minerals that dissolve slowly as groundwater moves through cracks in the rock. Sulfate comes from sulfide minerals in these same rock layers that break down over time as water passes through them.

Groundwater in Jackson County is high in iron and sulfur-bearing, driven by iron and sulfate dissolving from the bedrock as water sits in contact with it. The slow movement of water through tight fractures in the rock allows more minerals to dissolve into the water. These characteristics show up across wells throughout the county.

Wells in Jackson County commonly contain iron, manganese, and sulfate at levels that exceed EPA health standards. Iron can cause problems with the nervous system and organs over time. Manganese at elevated levels can affect how the brain develops and functions. Sulfate exposure over long periods can cause digestive issues including diarrhea and stomach pain.

Wells in this county often have high iron content that leaves rust-colored or orange-brown stains on sinks, tubs, and laundry. You may notice a metallic or bitter taste in the water, or a sulfur-like odor. The minerals can also create scale buildup on pipes and inside appliances, which can shorten the lifespan of water heaters and dishwashers.

We recommend testing your well water because every well is different and yours 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 $200-400 and will show you exactly what you are dealing with. Iron removal systems and water softeners can help address the mineral concerns once you know your levels.
