Water in Baraga County comes from the Jacobsville aquifer, which is an old sandstone and similar rock buried underground. This rock sits in layers and cracks where groundwater collects and flows. Your well taps into these underground spaces to pull out drinking water.
Iron and manganese come directly from the rock itself. As water sits in contact with the sandstone for years, these metals dissolve into the water. Arsenic also appears naturally in small amounts locked inside the minerals. The geology here does not filter these out as water moves through.
Your water is very hard and carries high amounts of dissolved minerals. Iron at 154 mg/L will stain fixtures and laundry orange or brown. The sodium and sulfate levels are high enough to taste salty or bitter, and the extreme hardness means scale builds up on pipes and appliances. You need treatment to address these issues.
Iron and manganese are found at levels that exceed EPA health standards in Baraga County wells. Arsenic is also present in the water, though at lower levels. Testing your well is important to know what you're drinking and to protect your family's health.
Long-term exposure to iron and manganese can cause health problems over time. Iron will stain your sinks, toilets, and laundry bright orange or brown. The very high hardness and sulfate levels mean your water will leave scale buildup on pipes and fixtures, and it may taste bitter or metallic.
Get your well tested through a state-certified lab right away. A basic health screen for bacteria and nitrate runs about fifty to one hundred dollars, while a full metals and minerals panel costs two hundred to four hundred dollars. A water softener combined with an iron filter can treat both the hardness and iron problems in your water.
