Why This Happens Here

Groundwater in Cheboygan County contains iron, arsenic, and chloride. Iron exceeds EPA health standards at moderate levels, while arsenic and chloride remain at low concentrations.

Iron dissolves naturally from minerals locked in the rock layers beneath this county. As groundwater sits in contact with these rocks over time, iron seeps into the water. Arsenic also occurs naturally in the same rock formations, and chloride enters from road salt applied during winter months.

Groundwater in this county is moderately hard, driven by iron that accumulates as water moves through the bedrock. The slow passage of water through cracks in the rock allows iron to concentrate in the water supply. Most wells in Cheboygan County show these same characteristics.

What This Means for You

Iron exceeds health standards in wells across Cheboygan County. Long-term exposure to elevated iron can affect your blood and organs. Arsenic and chloride are also found in some wells in this county, though at lower levels that pose less immediate concern.

Wells in this county show moderate hardness and iron levels that create visible quality-of-life problems. Iron leaves orange or rust-colored stains on sinks, toilets, and laundry. Your water may taste metallic or have an unpleasant odor from the iron content.

We recommend testing your well water to know exactly what you're dealing with. 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 treated properly. A basic health screen runs around $50-100, while a comprehensive metals and minerals panel costs $200-400. Iron filtration systems or water softeners can help address these issues.
