Soil & Terrain Characteristics

Northumberland County features Ridge and Valley terrain with limestone valleys and sandstone ridges. The Susquehanna River confluence area (Sunbury) has deep alluvial soils. The Shamokin area has been significantly impacted by anthracite coal mining, with disturbed soils and mine spoil. Limestone valley soils have karst features in some areas.

County-Specific Considerations

Northumberland County has a dual character: the southern portion around Shamokin has extensive anthracite coal mining legacy issues including mine subsidence, acid drainage, and contaminated soils. The northern portion is more agricultural with better soil conditions. The Susquehanna River and its North and West branches converge at Sunbury, creating flood risk. Well water in mining areas requires careful testing.
