Radon

EPA maps Philadelphia as Zone 3, the lowest predicted indoor radon (under 2 pCi/L average). Radon and air quality are covered in depth on lung.com.

The record for one specific address

County figures blur what matters: distance. The Address Environmental Report runs these same federal datasets against one address and reports every site, tank, polluter and water result around it, with distances, in about a minute.
