McMahon & Mann’s engineers have been retained in a number of projects involving remediation and containment of soil and groundwater contaminated with petroleum products, PCBs, volatile organic compounds and nuclear wastes. Some of the most visible of those projects include work at the West Valley Demonstration Project, the Occidental Chemical Company “S-Area” along the Robert Moses Parkway in Niagara Falls, and at St. Bonaventure University near Olean, New York.
