  • ENVIRONMENTAL MANAGEMENT: Algae recruited for waterways clean-up

    Most people have heard about the canary in the cage; the hapless sentinel that warns miners of lethal build-ups of poisonous gas by falling off its perch, dead. Researchers have applied a similar principle to their development of a procedure for identifying and removing toxicants from estuarine and coastal waters, using highly sensitive algae as toxicity test subjects. The use of such ‘lower ...

  • Geotube Dewatering Technology A Key Component In Hylebos Waterway Cleanup - Case Study

    The Hylebos Waterway was named after a 19th century priest who served parishes in Tacoma and Steliacoom, WA. For years, however, the name was associated with one of the largest Superfund sites in the nation. The Hylebos Waterway contains a toxic layer of sediment contaminated with PCBs, PAHs, arsenic, hexachlorobenzene, hexachloro-butadiene, and other organics and metals. The contamination comes ...

  • Waterways and ponds contaminated with pulp & paper PCBs are contained & dewatered using Geotube container, providing an economical environmental solution - Case Study

    Abstract: Polychlorinaled biphenyls (PCBs) were unknowingly generated in ihe waste of some of the pulp and paper systems, a known carcinogen in animals and a probable carcinogen in humans. PCBs are stable, man-made compounds. They absorb heat and do not easily break down. Because of these properties, they have been widely used in electrical equipment, hydraulic fluids, fire retardants, ...

  • The natural way to clean wastewater

    John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...

  • Piedroba Dewaters Slurry, Returns Clean Water to Holmes Beach Canals

    This project was a successful application of a total cleaning system (TCS), where the particular type of solids of the sediments permitted the dredger to avoid the costly construction of a dredged material maintenance area (DMMA), or the transportation and tipping fees for a municipal landfill. The surface waters were cleaned in tandem, and contributed to a higher quality benthic environment in ...

  • Geotube Dewatering Technology Provides Expertise in the Clean-Up of Contaminated Sediments - Case Study

  • RCAP and small systems can be a winning team

    The environmental regulatory community continues to clean up our waterways by requiring ever smaller communities to construct and operate wastewater collection and treatment systems. Many of these systems serve less than 100 homes, making affordability and management very difficult. In Ohio, the regulatory agency, the Ohio Environmental Protection Agency (OEPA), has realized this and has ...

  • Spill prevention, control and countermeasure

    Background One of the EPA’s mandates is to prevent oil spills from polluting our nation’s navigable waterways which are defined under the Clean Water Act and Oil Pollution Act as any waterway or body of water that is used for ...

Atlanta is faced with many obstacles on the way to meeting this challenge; a few of these include: Ongoing ...

  • Climate adaptive urban planning and design with water in Dutch polders

    The existing water management in Dutch polders is based on independent water systems for each polder. These are featuring artificial stabilized ground and surface water levels. As a result of the local climate the water levels in the polders are not continuously at a constant level. To maintain a stable water table in the polders, the surplus of relatively clean rainwater has to be pumped away ...
