Radon Mitigation Before & After Photos

Cambridge Aeration System install.

Customer had 24,000 pCi/l of radon in their well water. We installed a Cambridge aeration system capable of up to 99% of waterborne radon removal. The install included pre and post clear "big blue" filters to ensure high flow and minimize pressure loss. Post sediment filters are not always installed with aeration systems. But the water supply in this house had some iron in it. The owner didn't want a softener or iron filter, so we installed the post filter to capture any iron that might get oxidized in the aeration process.

Active Soil Depressurization (ASD) system installed to reduce elevated radon in air concentrations as low as possible. This home had a heavy bed of gravel and sub slab pipe which required the use of 4" PVC and a high volume radon mitigation fan. Because of the porous gravel bed under the slab, one suction point was all that was needed to successfully establish a negative sub slab pressure field.
