Shield Engineering

Featured Project

Appalachian State University contracted with Shield to assist the ASU Energy Center in evaluating the McDowell County Solid Waste Landfill as part of the development of community-based landfill gas utilization plans. Shield’s scope of work included obtaining required NCDENR permit approvals, establishment of a preliminary soil boring grid using Geoprobe technologies to map out existing methane concentrations, drilling of three extraction wells with 36-inch diameter borings, and conducting of a 48-hour methane extraction pilot test using a trailer-mounted 10-horsepower vacuum blower with generator. Methane concentrations, oxygen, carbon dioxide, and other specific field parameters, were field collected through out the duration of the pilot test.
