Newaygo County sits on mixed rock and sediment layers left behind by ancient glaciers. These underground layers—a jumble of sand, gravel, clay, and bits of older rock—hold the water that fills private wells in the area. The same mixed geology appears in all the neighboring counties around you.
Iron reaches high levels here because it naturally sits inside the sandy and rocky layers underground. As groundwater slowly moves through these materials over months and years, the water dissolves iron from the rock. Arsenic also comes from certain minerals locked in the bedrock. Chloride appears partly from road salt spread on winter roads, and partly from natural salt deposits deeper down. Sulfate leaches from minerals in the glacial sediment as water passes through.
The water in this area is extremely hard and mineral-heavy. Iron reaches 125 milligrams per liter—high enough to stain sinks, toilets, and laundry orange-brown. Sulfate at 14,000 milligrams per liter and sodium at 6,200 milligrams per liter make the water taste salty and bitter, cause scale buildup on pipes and water heaters, and can bother people watching their salt intake. These mineral levels mean most well owners here benefit from treatment systems.
Iron in Newaygo County well water exceeds EPA health standards. Arsenic and chloride are also detected in the area's groundwater. Testing your well is important to understand what's in your water and whether treatment is needed.
Long-term exposure to iron at these levels can stain sinks, toilets, and laundry orange or brown. The high sodium and sulfate in this area's water creates crusty white buildup on pipes, faucets, and inside water heaters. You may notice a metallic taste or salty flavor. These mineral levels wear out appliances faster and make cleaning harder.
Get your well tested by a state-certified lab. A basic health screen runs $50–100, while a comprehensive mineral and metals panel costs $200–400. Ask the lab to test for iron, arsenic, sodium, and sulfate. An iron filter system can remove staining and protect your pipes and appliances.
