Radon Mitigation Photo Album: Sub Slab Depressurization

The apartment complex’s property management company conducted radon sampling in one ground-floor unit per building. One unit recorded radon levels exceeding the EPA action level of 4.0 pCi/L. Idaho Radon installed a sub-slab depressurization system, which successfully reduced the average radon concentration to 0.6 pCi/L.
