Wyandot County groundwater contains iron, manganese, and sulfate at levels that exceed EPA health standards. These contaminant levels are high enough to require attention.
The bedrock beneath this county is made of ancient rock layers containing iron-bearing minerals and sulfate-rich deposits. As groundwater moves slowly through cracks and fractures in this rock, water dissolves these minerals naturally, releasing them into the water that feeds your well.
Groundwater in this county is very hard, driven by elevated calcium and magnesium from the limestone below, along with high iron and sulfate concentrations. The slow contact between water and these mineral-rich rock layers causes these characteristics to develop. Hard water and elevated iron are widespread across wells throughout the county.
Iron, manganese, and sulfate all exceed EPA health standards in wells throughout Wyandot County. Iron and manganese can harm your brain and nervous system over time with long-term exposure. Sulfate at high levels can cause digestive problems, especially for infants and people with certain health conditions.
The water in this county is extremely hard, which means you will see thick white crusty buildup on faucets, showerheads, and inside pipes. Iron stains sinks, toilets, and laundry orange-brown. The extreme hardness can shorten the lifespan of water heaters, dishwashers, and other appliances. Sulfate can give the water a bitter taste or rotten-egg smell.
We recommend testing your well 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 water so it can be properly treated. A comprehensive metals and minerals panel typically costs $200-400. Treatment options include a water softener paired with an iron filter.

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.
