Soil & Terrain Characteristics

Lebanon County lies within the Great Valley (Lebanon Valley) with predominantly deep limestone-derived soils. The fertile valley soils provide good drainage for conventional systems but are susceptible to karst sinkholes. The northern portion along Blue Mountain has thin, rocky soils over Tuscarora sandstone. Cornwall Hills feature iron-rich soils from historic ore deposits.

County-Specific Considerations

The Lebanon Valley's limestone karst terrain presents significant challenges for septic system siting. Cornwall and the surrounding area have a legacy of iron ore mining that affects soil chemistry and groundwater quality. Fort Indiantown Gap Military Reservation in the northern part of the county represents a large area of restricted development. The county's agricultural base adds nitrogen loading pressure to groundwater resources.
