Iron, arsenic, and chloride are present in groundwater across Hutchinson County. Iron exceeds EPA health standards at moderate levels, while arsenic and chloride remain below concerning thresholds.
Iron and arsenic occur naturally in the rock layers that make up the High Plains aquifer in this region. As groundwater moves slowly through these sandy and gravelly underground layers, it dissolves iron from the rock. Chloride accumulates in the water from the natural minerals present in these ancient sediments. All three contaminants reflect the composition of the aquifer itself rather than pollution from human activity.
Groundwater in this county is very hard, driven by elevated calcium and magnesium from the rock materials in the High Plains aquifer. The sandy and gravelly layers that hold water here contain minerals that dissolve easily as water passes through, adding these hardness-causing elements to wells throughout the area. Very hard water is widespread across wells in Hutchinson County.
Iron appears in wells across Hutchinson County at levels that exceed EPA health standards. Long-term exposure to elevated iron can cause problems with your liver and heart. Arsenic is another contaminant found in county groundwater and poses serious health risks with exposure over time, affecting multiple organs in your body.
The very hard water in this county creates real problems for everyday life. You will see white scale buildup on faucets, shower heads, and inside pipes. Hard water makes it difficult for soap to work well and can leave your skin and hair feeling dry. The extreme hardness shortens the lifespan of water heaters, dishwashers, and other appliances that use hot water.
We recommend testing your well water to find out exactly what you are dealing with. Every well in this county is different, and yours could have higher or lower levels than what is common here. A comprehensive metals and minerals panel costs between $200 and $400 and is the only way to know what treatment your family actually needs. Iron filters and water softeners are two options that address the main concerns in your area.

MCL = Maximum Contaminant Level (EPA limit for public water; used as benchmark for private wells). Distribution shows % of sampled wells in each concentration band. Methodology.
* Microbial contaminants (E. coli, coliform) reflect only samples from the last 10 years.
