Where We Work

Radon Mitigation Across the Twin Cities metro

Serving Hennepin, Ramsey, Dakota, Washington and Anoka counties. The EPA maps Hennepin, Ramsey, Dakota and Washington as Zone 1 and Anoka as Zone 2 — and houses above the action level turn up in both. What changes across the metro is the ground: glacial till to the west and south, outwash sand across the Anoka Sand Plain, limestone and sandstone under the river bluffs in St. Paul and Minneapolis. Each one moves soil gas differently.
