Source: mlive.com COMSTOCK TOWNSHIP, MI — This is the last summer the Kalamazoo River will be the scene of heavy dredging activity, as Enbridge Inc. cleans up the mess from a pipeline leak that sent an estimated 800,000 gallons of crude oil into Talmadge Creek and the river. Nearly four years later since the spill was discovered July 26, 2010 near Marshall, the Canadian pipeline company is wrapping up the cleanup. Comstock Township Supervisor Ann Nieuwenhuis said the work in her eastern Kalamazoo County township has carried on pretty much out of public view and apparently without a hitch. “Every...Continue Reading

The Initial Project At one time, over 4 million gallons (1,514 million liters) of toxic semi-treated sewage flowed into Palm Bay Florida’s Turkey Creek. As a result, Turkey Creek contained extremely high levels of harmful toxins and nutrients. During the spring of 2017, the team from Gator Dredging spent most of their time focused on cleaning up the mess that once occupied Turkey Creek, removing over 236,000 yd3 (180,435 m3) of muck, nitrogen, and phosphorus contamination. The Right Kind of Equipment When working on a project the size of Turkey Creek, you need the right kind of equipment. For this...Continue Reading

DNREC’s Divisions of Watershed Stewardship and Fish & Wildlife have announced plans for a cooperative dredging project on the Little River near Dover, from the Route 9/Bayside Drive bridge in Little Creek east into the Delaware Bay. Dredging is scheduled to begin in the second week of this month. Southwind Construction of Evansville, Ind., was awarded the contract for the project and will be using their 14″ Ellicott®  Brand 970 dredge. The channel is approximately 12,400 feet long and will be dredged to widths of 40 feet in the river portion and 60 feet in the Delaware Bay portion, and...Continue Reading

The Lake Hermitage Marsh Creation – NRDA Early Restoration Project involves the creation of marsh within a project footprint known as the “Lake Hermitage Marsh Creation Project” developed for and funded through the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) Program. This project substitutes approximately 104 acres of created brackish marsh for approximately 5-6 acres of earthen terraces that would otherwise have been constructed within the CWPPRA project boundary. The Lake Hermitage Marsh Creation – NRDA Early Restoration Project will create approximately 104 acres of brackish marsh in lieu of the 7,300 linear feet of earthen terraces that was...Continue Reading

Buenaventura Bay, Colombia Source: World Dredging Mining & Construction Introduction One of the first geotextile tube applications in Colombia was for the construction of confined disposal area islands that will be used for containment and dewatering of fine-grained maintenance dredged materials. The project is located on the San Antonio Inlet, Buenaventura, Colombia. The dredged material containment area is the first of two oval-shaped islands planned in this riverine and tidal environment. This new and innovative construction methodology involved hydraulically filled geotextile tubes with a sandy fill material. The geotextile tubes were positioned end to end to provide a perimeter dike for...Continue Reading

August 2001 FOR IMMEDIATE RELEASE The most maneuverable dredge ever built. New 8-inch (203 mm) discharge, electric swinging ladder dredge (SLD) for tailings reclamation and pond maintenance with three (3) traveling spud carriages, using no cables. Ellicott® International, a leading dredge manufacturer of environmental dredges, announces a new type of dredge which actually walks by itself. The dredge moves on three moving spuds or traveling carriages enabling it to remain in the exact position at all times because there are always two spuds firmly anchored in the bottom. It walks with the spuds while floating on the surface. This positioning...Continue Reading

Source: Jim Gordon Clearwater News & Bulletins The completion of a PCB dredging project along Lake Champlain in Plattsburgh, NY, has demonstrated that PCBs can be safely dredged from the Hudson River. Along the Lake Champlain shoreline waterfront homes were undisturbed, swimming beaches and motels stayed open during the three-year process, and former skeptics of dredging are now praising the operation. ‘I was not in favor of it initially. I was concerned about stirring stuff up. It did not make a lot of sense to me,’ said Dr. Djell Dahlen, an eye surgeon whose expensive home is immediately adjacent to...Continue Reading

Source: by March A. Torre – CE News for The Business Of Civil Engineering Large tubes filled with dredged material have been used in a variety of coastal and inland projects. The tubes, manufactured of high strength polyester or polypropylene geotextile, are hydraulically filled with a dredge, such as an Ellicott® brand Series 370 or larger Ellicott® brand”Dragon®” cutter dredge. The geotextile tubes are typically filled with on-site material; however, alternate materials can be imported and used. Typical applications would include: sand dune restoration, dike construction, groin construction, artificial reefs, and simple waste containment. The tubes are filled in-place and...Continue Reading

16 March 1999 Source: Eric Staats, Naples Daily News Crews from Ludlum Construction Company are scheduled to start pumping sand out of Clam Pass today as part of the effort to restore a dying mangrove forest in northern Collier County, the director of the country division overseeing the project said Monday. The restoration plan is aimed at increasing water flows in and out of Clam Bay, where flooding has killed more than 50 acres of mangroves since 1992 below the balconies of Pelican Bay’s high-rise condominiums. The Clam Pass work is the second piece of the restoration to get under way. Crews...Continue Reading

2 January 1999 Source: Baltimore Sun In an unusual partnership, environmentalists, polluters, local municipalities and the Environmental Protection Agency are working together to clear out the toxic gunk that’s clogging the Ashtabula River near Lake Erie. Their common goal is to start dredging the river without the years of lawsuits and studies typical of cleanups done under the Superfund law. Layers of heavy metals and cancer-causing PCBs have contaminated the river-bottom silt. Dredging would not only clean up the pollution but would accommodate more boat traffic on a channel that flows into Lake Erie at Ashtabula, in Ohio’s northeast corner....Continue Reading
