“…The United States Army Corps 2021 Project Delivery Team (PDT) of the Year Award for Excellence for the DuPont Chambers Works FUSRAP Project, is truly a testament to the outstanding support and collaborative efforts of the Sevenson team. This award and the achievements that led to it have enhanced the reputation of Sevenson, the Philadelphia District, North Atlantic Division and the FUSRAP program.”

“…As the United States Environmental Protection Agency project manager, it is my responsibility to task the Army Corps of Engineers to perform environmental response activities at the Cornell-Dubilier Electronics Superfund (CDE) site.  The Army Corps of Engineers then directs the contractor (Sevenson Environmental Services) to execute the work.  Within the context of this working relationship, I provide the following recommendation for Sevenson at the CDE site.”

“I have had the pleasure of interacting with Sevenson since January 2011.  The intrusive nature of the remediation at the CDE site has been a concern for EPA, local residents, commercial property owners and tenants, as well as elected officials.”

“…has demonstrated an outstanding ability to work in a positive and constructive manner with all interested parties which has been critical to the success of this project.”

“…has employed strong leadership and communication skills necessary to provide effective direction to multiple remediation crews deployed throughout the community.”

“…the high quality results of the environmental remediation and restoration work performed at the site.”

“On repeated occasions, EPA personnel have received positive comments and praise from residents within the affected community concerning the high quality of Sevenson’s work.”
