  • 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 ...

  • How to identify issues in water quality

    Water quality can mean different things to different people and therefore depends on what standard of quality one is looking for, for example, water may be fine for fish to live in but lack the quality required for human consumption. To measure the quality of water accurately, tests are carried out to identify several key indicators. These characteristics are then compared ...

  • 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 ...

  • Geotube Dewatering Technology Unclogs Queen’s Creek and the Queens Lake Marina Waterways - Case Study

    Dredging contractor uses cost effective and innovative dewatenng technology to contain and dewater marine sediments. A build-up of organics, sediments, very fine silt and clay created a major navigational problem for members of the Queens Lake Marina Association, in York County, VA. A contract was issued to dredge and dewater sediments in the boat slips and outside the enclosed slip area. Site ...

  • Effects of hydrodynamically rough grassed waterways on dissolved reactive phosphorus loads coming from agricultural watersheds

    Received for publication October 5, 2007. A modified type of grassed waterway (GWW) with large hydrodynamic roughness has proven ability to reduce sediment load and surface runoff under conditions where best management practices on the delivering fields reduce sediment inputs that could otherwise damage the grass cover. It is unknown how such a GWW affects the loading of surface runoff with ...

  • 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, ...

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

    Geotube units offer an effective solution for contaminated sites to manage the recovery and containment of PCBs, heavy metals, BTEX, PAHs, PACs, and other hazardous materials. Contaminated sediments are a common problem for communities and industries around the world. Past spills, leaks, discharges, and improper disposal or management of hazardous materials and wastes often result in ...

  • 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 ...

  • NAUE shores up Schwarze Elster´s detour case study

    Lusatia is a region in Germany and Poland. The original  meaning of Lusatia is something along the line of “swampy, wet  meadows.” Lusatia is separated into two parts that, in terms of the landscape, are completely different: Upper Lusatia and Lower Lusatia. In the Northwest, Lower Lusatia is bordered by the Fläming ridge; and in the West it’s bordered by the ...

  • Urban Stream Restoration: Standing Up to the Toughest Weather Conditions

    Project In 2008, the City of Altanta faced a large problem: the single-lane road that provides the only entry point to its SWAT team training center was likely to be lost completely to erosion. Although the road had been lined with concrete barriers as a stop-gap measure, it was clear that more substantial action was required to save it. Because the road is situated on a narrow ...

  • ASTM Standards Help Meet Need for Clean Water

    The new ASTM Water Portal provides a single access point to standards and related information about ASTM International’s diverse committees working to protect and monitor this vital global resource. Clean and safe water is the underpinning of the quality of life for people around the world. Global economies depend on water, whether it’s to support the manufacturing of goods ...

  • 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 ...

  • Groundwater & Wastewater applications notes

    The Clean Water Act (CWA) and Resource Conservation and Recovery Act (RCRA) were designed to limit the amount of contaminants that are discharged into waterways and combat the level of organic pollution in the environment. Horizon Technology takes a strong stand on these topics and offers many Application Notes regarding the ...

  • 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 ...

  • Raising Dead Ships: Derelict Vessel Removal

    One of Global’s specialties is vessel salvage – if your vessel runs aground or sinks, we’ll raise it and hopefully refloat it for you. But what happens to the thousands of old, worn out vessels that sit abandoned along the coasts and harbors? Often they sink, where they pose an environmental and navigational hazard. That’s why Washington, Oregon, California and Alaska have ...

  • 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 ...

  • What is stormwater?

    Stormwater runoff, water that isn’t absorbed into the ground after a weather event, is a potential water source that cities across the world have struggled with for decades. Why is coping with it such a challenge? Whether the precipitation is water or ice, its addition to the environment can be a problem, especially when a lot of it falls in a short amount of time. When this occurs in ...
