Well Water in Kalamazoo County: What to Test and Why

The water here comes from the Marshall sandstone, an old layer of sand and rock buried underground. This layer sits deep below the surface and holds water in the spaces between the grains of sand. Groundwater moves slowly through this sandstone, picking up minerals as it goes.

Manganese, chloride, and sulfate all come from the rock itself. As water sits in the sandstone for a long time, these minerals dissolve out and mix into the groundwater. The deeper parts of this rock layer have very little oxygen, which helps manganese and other metals dissolve more easily into the water.

The water here is very salty and full of minerals. The sodium level is extremely high at 10,500 parts per million, and sulfate is at 27,000 parts per million. This means the water will taste salty and bitter, and minerals will build up quickly on pipes and faucets, causing scale and damage over time.

Manganese, chloride, and sulfate are found at levels that warrant testing in Kalamazoo County well water. All three exceed EPA health standards. The manganese is the biggest health concern for your family, especially young children.

Manganese at these levels can harm brain development in children and cause memory problems in adults over time. Your water will also likely taste salty or bitter from the chloride and sulfate. You may see staining on fixtures and scaling inside pipes from the high mineral content.

Get your well tested by a certified lab—a basic health screen runs $50–100, but a comprehensive panel runs $200–400 and will show exactly what you're dealing with. If testing confirms elevated manganese, a whole-house treatment system with oxidation filters can remove it effectively.
