Groundwater in Emmet County contains iron, arsenic, and chloride. Iron exceeds EPA health standards in this county's wells, though arsenic and chloride remain at low levels.
Iron dissolves naturally from minerals locked in the bedrock below. As groundwater sits in contact with these rock layers over time, iron seeps into the water. Arsenic also occurs naturally in the same rocks, while chloride appears from road salt that filters down through soil.
Groundwater in this county is hard, driven by elevated calcium and magnesium from the limestone and dolomite bedrock. The slow movement of water through cracks in this rock allows these minerals to dissolve and concentrate. Hard water is common across most wells in Emmet County.
Wells in this county contain iron at levels that exceed EPA health standards. Long-term exposure to elevated iron can affect how your body processes oxygen and may harm organs over time. Iron is not an immediate poison, but drinking water with high iron for years is a health concern worth addressing.
Wells in this county are also very hard. Hard water leaves white crusty buildup on faucets, showerheads, and pipes. Iron causes orange or rust-colored stains on sinks, toilets, and laundry. The water may taste metallic. Over time, mineral buildup can shorten the lifespan of water heaters and dishwashers.
We recommend testing your well to find out what is actually in your water. 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 needs treatment. A basic health screen runs around fifty to one hundred dollars. An iron filtration system can remove iron, and a water softener handles hardness.

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.
