Radon mitigation in East Helena
Radon help for the small city about five miles east of downtown Helena, near Prickly Pear Creek.
East Helena is its own incorporated city, with 1,944 residents and 915 housing units at the 2020 census. It grew up around a smelter that was built in 1888 and processed silver-lead ore until 2001, and an Anaconda Company zinc plant operated there from 1927 to 1972. The town has its own K-12 school district, East Helena Public Schools.
Is the smelter connected to radon?
No. The EPA designated East Helena a Superfund cleanup site in 1984 because smelting left heavy metals and arsenic in soil and water. Radon is a separate issue: a natural gas that comes from uranium decaying in the ground, found in every state. Living in East Helena doesn't make your radon higher or lower than a house in Helena, and the only way to know your level is a test.
Digging a suction pit near cleanup areas
A sub-slab system involves coring the floor and removing a small amount of fill, and an exterior pipe may mean a little digging along the foundation. If your property had soil work done as part of the cleanup, tell the radon company when you call so they can plan how to handle anything they remove.
