Why This Happens Here

Groundwater in Morrow County contains iron, manganese, chloride, and sulfate at levels that exceed EPA health standards. These contaminant levels are concerning and require your attention.

The rock layers beneath Morrow County naturally contain these metals and minerals. As groundwater moves slowly through cracks in the rock, iron and manganese dissolve into the water. Sulfate and chloride come from the same source--minerals naturally present in the bedrock that release into water over time.

Groundwater in this county is very hard, with elevated calcium and magnesium from the limestone below. Iron also contributes to the water's character. These characteristics are widespread across wells throughout the county.

What This Means for You

Wells in Morrow County commonly contain iron, manganese, chloride, and sulfate at levels that exceed EPA health standards. Iron and manganese can build up in your body over time and damage your nervous system and organs. Chloride and sulfate at these levels can affect kidney function and cause digestive problems with long-term exposure.

The water in this county is extremely hard, which means mineral buildup will coat your pipes, water heaters, and dishwashers and shorten their lifespan. Iron causes orange-brown stains on sinks, toilets, and laundry. You may also notice a bitter or metallic taste in your water, and the high sulfate can give it an unpleasant smell.

We recommend testing your well water with a comprehensive metals and minerals panel, since multiple contaminants exceed health standards. Every well is different, and your well 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 water so it can be properly treated. A comprehensive panel typically costs $200-400, and treatment options like a water softener combined with an iron filter can help address these concerns.
