Radon Mitigation in Clearfield
Moderate radon risk from Pennsylvanian sandstone and shale of the bituminous coal field on the Appalachian Plateau. Clearfield sits on the West Branch Susquehanna where Pennsylvanian coal measures and underlying Mississippian formations contain variable uranium concentrations. Unlike the anthracite fields of northeast PA, the bituminous coal region's broader geology and thicker soil cover generally moderate radon levels — but fractured zones and former surface mining areas create localized elevation.
High Radon Risk Area
Clearfield is in EPA Zone 1 — Moderate radon risk from Pennsylvanian sandstone and shale of the bituminous coal field on the Appalachian Plateau. Clearfield sits on the West Branch Susquehanna where Pennsylvanian coal measures and underlying Mississippian formations contain variable uranium concentrations.

Local Geology & Risk Factors
Clearfield is located in an area with Appalachian Plateau / Pennsylvanian Sandstone-Shale Coal Measures geology, which contributes to elevated radon levels. The Pennsylvania DEP identifies this region as having significant radon potential due to uranium-bearing rock formations.
Testing is essential because radon levels can vary significantly between neighboring homes based on construction, soil permeability, and ventilation.
