Well Water in Montmorency County: What to Test and Why

Your well water sits in old limestone and related rock layers deep underground. These rock formations have tiny cracks and spaces that hold water. The same type of rock stretches across several counties in this part of Michigan.

Iron comes from the rock itself as groundwater slowly passes through it over many years. Arsenic occurs naturally in certain spots within these old rock layers. Chloride and sulfate also enter the water as it moves through the rock, picking up minerals along the way. The rock structure here protects the water from surface pollution.

The water here is extremely mineral-rich, which means it is very hard. Iron at 250 parts per million will stain sinks, toilets, and laundry orange or reddish-brown. Sodium at 3200 and sulfate at 5500 parts per million mean the water tastes salty and can cause scale buildup on pipes and fixtures that shortens their lifespan.

Iron in Montmorency County well water exceeds EPA health standards. This is a concern that warrants action, though it is not an emergency. Arsenic and chloride are also present in local groundwater but at levels that need monitoring. Getting your water tested through a certified lab will tell you exactly what you are dealing with.

Long-term exposure to iron can harm your health, but the biggest problem you will notice first is staining. Iron leaves orange or reddish-brown marks on sinks, toilets, and laundry. Your water may taste metallic or have a strange odor. The extremely high sodium and sulfate levels mean your water is also very hard, which causes white, crusty buildup on pipes and faucets that can shorten their lifespan.

Get your well tested by a state-certified lab. A basic health screen for bacteria and nitrate costs around fifty to one hundred dollars. A comprehensive mineral and metals panel typically runs two hundred to four hundred dollars. A whole-house iron filtration system paired with a water softener can treat multiple problems at once.
