Radon Mitigation in Media
High radon risk from Wissahickon schist and associated Piedmont metamorphic rocks underlying Delaware County's upland plateau. Media, as the county seat, sits on Precambrian to early Paleozoic schist and gneiss with naturally elevated uranium content. The Wissahickon formation's foliated structure creates planar fracture pathways that channel radon gas efficiently toward the surface.
