CT Radon and Well Water Solutions Before & After Photos

CT Radon and Well Water Solutions was called out to a home in Norwalk CT to investigate a house that was built entirely on a dirt crawl space. Elevated radon levels of 10+ pCi/l were recorded in multiple living areas over the crawl space.

We went out to the home and found that the house was built entirely over exposed dirt crawl spaces.

CT Radon and Well Water Solutions was hired to mitigate the property. We installed a cross-laminated poly vapor barrier over the entire dirt floor footprint. We then installed suction pipes through the barrier and routed them to the home's exterior where we connected an in-line fan to the pipe network to create suction under the barrier and expel the soil gas outdoors above the roofline. Post-mitigation testing revealed results of < 1.0 pCi/l in all living areas.

Customer had a well tank and plumbing connections that showed signs of severe corrosion. He also had an old aeration system for waterborne radon removal that had been in bypass for years due to constant malfunctions. We removed the old pressure tank and aeration system and installed a new pressure tank, along with a neutralizer to reduce corrosion, and a GAC system for waterborne radon removal. Customer now has a neutral pH, low radon levels, and better water pressure, and no fear of the corroded fittings letting go.

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.
