Descriptions of projects related to Superfund site restoration and redevelopment are provided in the following:
Millcreek Superfund Site Restoration and Redevelopment
D’Appolonia was retained by the PRP Group for the Millcreek site to review the remedial design. The original design was found to have some deficiencies, and D'Appolonia prepared a revised design that addressed some technical problems and saved an estimated $1.3 million in construction costs. We then prepared a conceptual design for a 9-hole golf course and golf teaching center, which was subsequently constructed on the site. The implemented reuse option provided a recreational benefit to the community while maintaining the integrity of the landfill cap system.
Slope Stability Evaluation at New England Superfund Site
During a remedial investigation of a Superfund Site that was a former municipal disposal area, two large scarps were observed behind the crest of steep debris slopes on the flanks of the disposal area. Because the disposal area was on a hillside above a river, the steep slopes and scarps caused concern relative to the possibility of continued slope movements and eventual contamination of the river. D’Appolonia was retained to develop a geotechnical exploration program, to evaluate the stability of the debris mass, and to develop remedial design concepts to allow site closure.
