About this River Falls radon guide

An independent radon resource for homeowners in River Falls and the St. Croix Valley.

What it covers

Peak Radon River Falls explains radon for people living on the Wisconsin side of the state line. That means testing, what the results mean, how mitigation systems work, and how Wisconsin’s rules compare with Minnesota’s, which matters when contractors and advice come from both states.

Rules and figures on this site link back to Wisconsin DHS, the Minnesota Department of Health, Minnesota statutes, or the EPA.

What it doesn’t do

This site doesn’t test homes, install systems, or sell anything. When you need a professional, we show you how to check credentials so you can choose.

It also isn’t connected to the radon company that previously used this web address. If you’re looking for whoever installed your existing system, check your install paperwork or search the national certification lists for someone who can service it.

One more thing

Nothing on a website can tell you your radon level. A test can.
