Radon testing & mitigation in Phoenixville, PA

Phoenixville sits in Chester County. In the PA DEP test dataset, 16,364 basement radon tests carry a Phoenixville address. Their median was 2.2 pCi/L, and 27% came in at or above EPA's 4 pCi/L action level. Across all of Chester County it was 31%, and statewide 37%. Even where the average is lower, neighboring houses can test very differently, so every home should be tested.
