ARCADIS to clean up river systems in the U.S.

ARCADIS, the international consultancy, design, engineering and management services company, announced today that it has been awarded a $54 million contract to manage an environmental sediment remediation project in the tidal Lower Passaic River in Newark, N.J, one of the most complex and industrial river systems in the U.S.

The project involves dredging, dewatering and off-site disposal of approximately 40,000 cubic yards of the most heavily contaminated sediment from the river. These actions will help create and maintain a more healthy and sustainable river environment.

The project is anticipated to start this July and continue through late 2012. The team will install an enclosure around the work area prior to removing any sediment, which will support existing shoreline structures and minimize movement of any re-suspended sediment. After removal, the sediment will go through a dewatering process with subsequent treatment of the effluent, and the sediments will then be transported out-of-state for ultimate disposal.
