Radon Mitigation in Hanover
Radon potential varies house-to-house across Hanover's folded sedimentary bedrock — thin-bedded limestone, shale, and closely folded sedimentary rock of the Hanover-York district. Local bedrock structure and fracturing influence how soil gas moves into homes, so site conditions and foundation type often matter as much as zone-wide averages. Testing is the only way to know a specific property's level.

Local Geology & Risk Factors
Hanover is located in an area with Hanover-York District / Folded Sedimentary Belt 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.
