Soil & Terrain Characteristics

Dauphin County spans multiple physiographic regions from the Great Valley limestone lowlands around Harrisburg to the Ridge and Valley sandstone and shale ridges in the north. The Susquehanna River corridor has alluvial and flood plain soils. Northern Dauphin (Lykens Valley area) has rocky, mountain soils over folded Appalachian sedimentary bedrock. Coal measures in the northeastern portion have been mined.

County-Specific Considerations

Dauphin County includes the state capital Harrisburg, which is fully sewered, but the northern half of the county is rural and heavily dependent on on-lot systems. The Lykens Valley area has a legacy of anthracite coal mining that affects soil conditions and well water quality. Three Mile Island is located in the Susquehanna River within the county, though its environmental impact on septic and well systems is minimal.
