Groundwater in Traverse County contains arsenic, radon, nitrate, and chloride along with high levels of iron, manganese, and sulfate. Multiple contaminants exceed EPA health standards, making testing and treatment important for well owners here.
The rock beneath Traverse County naturally holds these substances. Iron and manganese leach from the surrounding stone into the water as it flows underground. Nitrate and chloride seep down from fertilizers and road salt used above ground. Radon comes from the decay of uranium in the rock itself.
Traverse County water is very hard and high in iron and sulfate. The local rock dissolves as water passes through it, releasing calcium, magnesium, and sulfate into the groundwater. Iron and manganese are especially common across wells throughout the county due to the composition of the rock layer that supplies drinking water.
Wells in Traverse County commonly contain arsenic, chloride, fluoride, nitrate, and radon at levels above EPA health standards. Arsenic is a poison that builds up in your body over time and increases cancer risk. Nitrate is especially dangerous for babies and can cause serious illness. Radon is a radioactive gas that increases lung cancer risk. Fluoride at high levels can damage tooth enamel and bone. Manganese can harm your nervous system with long-term exposure.
The very hard water in this county causes stubborn staining from iron and leaves deposits on fixtures and inside pipes. You may notice rust-colored stains on sinks and laundry. High sulfate and sodium levels can make water taste metallic or bitter. Hard water reduces how well soap works and shortens the lifespan of water heaters and dishwashers. Your appliances will wear out faster than normal.
We recommend a comprehensive water test since your well may differ from what is common in the county. Your well could have higher or lower levels of these contaminants. Testing is the only way to know what is actually in your water so you can treat it properly. A comprehensive metals and minerals panel costs between two hundred and four hundred dollars. Treatment options like reverse osmosis filters or water softeners can address multiple concerns.

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.
