Mariners are advised of sediment sampling collection activities in the channels of Patterson Lakes. Works will consist of collection of sediment samples from a moored barge. The barge will be stationary for periods of approximately 30 minutes before moving to the next sampling point. Samples will be collected from berthing areas adjacent to jetties or [...]
The Washington Department of Ecology (Ecology) has adopted changes to the state’s standards for cleaning up contaminated in-water sediments. The changes take effect Sept. 1, 2013. In 1991, Ecology first adopted the Sediment Management Standards (SMS) for guiding the management of sediments. The SMS rule is used to conduct environmental cleanup work, manage the dredging [...]
![Spain: Oceana Protests Over Sediment Dumping Plans]()
Oceana is protesting about Spanish plans to dump Mercury-rich sediment dredged from a Minorcan harbour into the open ocean. The organisation has requested the Spanish Institute of Oceanography (IEO) report on management of the material extracted in the dredging of Mahón harbour. This project involves the extraction of 200,000 m3 of sediment, with a mercury [...]
The Fox Waterway Agency has proposed constructing a 29-acre in-lake sediment storage and dewatering facility (SDF) using beneficially reused dredged sediment. The Fox Waterway Agency will improve navigation by hydraulically and mechanically dredging sediment from the Chain O’Lakes and Fox River and transporting the material via pumping or barge to the newly constructed island. The [...]
The Office of Acquisition Management has invited bidders to submit their offers for the sediment profile imaging contracts at the Mayport Harbor and Port Everglades areas. The Government intends to award a purchase order resulting from this solicitation to the responsible offeror whose offer best conforms to the specification, meets the Government’s delivery schedule and [...]
On Wednesday, the U.S. Environmental Protection Agency will hold a community meeting to discuss the final results of its radiological investigation at the Santa Susana Field Laboratory (SSFL). EPA has officially completed its field work and has collected a total of 3,735 soil and sediment samples and 215 groundwater and surface water samples which were [...]
Damen Dredging Equipment has commissioned the brand new sediment transport test circuit in the presence of the members of the Dutch Civil Engineering Society on the 24th of November last. The slurry test circuit is a part of the DDE innovation program, taking the search for better dredging components to the next level. The sediment [...]
