Pittsburgh District geotechnical engineers and geologists study subsurface terrain to assess bedrock for construction projects. A marine drilling crew has been working at Emsworth Locks and Dams since July to drill more than 50 boreholes. The geotechnical team will send samples to a lab to identify the bedrock hardness, strength and permeability for construction. The district plans on constructing a newer, larger lock chamber at Emsworth as part of the Upper Ohio Navigation Project.
