Dredge Material Management Program
EEA has undertaken numerous dredge material management studies over the past fifteen years. Services included delineating contaminated sites, creation of wetlands using dredged material, landfill cover, and upland disposal. EEA maintains state-of-the-art vibratory coring equipment including Rossfelder P-1 electric vibratory corer, hand corers, split spoon augers, drop hammers, and a Geoprobe LT54 direct push corer sampler.
SOME OF OUR PROJECTS.....
NEW BEDFORD HARBOR PCB SUPERFUND SITE
As a subcontractor to Foster Wheeler, Inc., EEA completed over six hundred vibratory and gravity cores in the New Bedford Inner and Outer Harbors during the past two years to assist in delineating the PCB contamination hot zones and to map the vertical and horizontal PCB concentrations throughout the Harbor.
PORT AUTHORITY VIBRATORY CORING STUDIES
Client: Port Authority of New York and New Jersey/EA Science Engineering and Technology
EEA, Inc. has performed numerous vibratory coring surveys to assist the Port Authority in developing dredging plans in and around Howland Hook Marine Terminal, La Guardia Airport, and various other Port Authority owned/operated facilities along the Hudson and East Rivers.
FRESHWATER WETLAND CREATION USING DREDGED MATERIAL
Recently, under contract to a New York City agency, EEA developed a concept of using dredged sediment material as a substrate for the creation of a freshwater wetland. This plan would provide the client with a number of significant advantages, including a unique and beneficial dredge material disposal option, creation of a wetlands mitigation bank and the benefits of a "green project." EEA also developed a wetlands creation plan for stormwater control at an industrial facility in Newark, New Jersey.
BROOKLYN NAVY YARD
The Brooklyn Navy Yard requested a feasibility study to determine if dredge spoil material from their main basin could be used to fill in Wallabout Channel. This channel currently is not being used within the Navy Yard since the cessation of ship construciton and repair. Numerous water, ecology, sediment chemistry and fisheries programs were conducted by EEA scientists. A permit application has been submitted.
SCUFFLETOWN CREEK, NORFOLK VIRGINIA
Client: U.S. Army Corps of Engineers/Foster Wheeler, Inc.
EEA, Inc. has developed a portable vibratory coring system, which can be readily deployed on hired vessels throughout the United States. EEA recently mobilized a coring system and crew to assist Foster Wheeler to collect sediment samples, which were used to further define limits of contamination from a specific point source within Scuffletown Creek.
