An independent consumer guide for home water decisions.
Home Water Compass helps homeowners identify their likely water source, understand what is actually known about it, and choose one honest next step: learn more, get an appropriate test, compare technically suitable products, or talk to one named local professional.
We are not a utility, a laboratory, a regulator or a government program — and we cannot test the water at your tap. What we can do is make the decision in front of you clearer.
