  • Experimental and numerical investigation of interactions between above and below ground drainage systems

    This paper presents the results of the experimental and numerical investigation of interactions between surface flood flow in urban areas and the flow in below ground drainage systems (sewer pipes and manholes). An experimental rig has been set up at the Water Engineering Laboratory at the University of Sheffield. It consists of a full scale gully structure with inlet grating, which connects the ...

  • Behavior of energetic materials in ground water at an anti-tank range

    An environmental issue has arisen with M-72 malfunction on anti-tank ranges because many of these rockets break into pieces without exploding on impact, dispersing their energetic materials content on the ground surface and exposing them to transport by infiltration of rainfall and snowmelt. A case study (1998–2005) at Arnhem Anti-Tank Range (Garrison Valcartier, Canada, in operation since the ...

  • Common Treatment Technologies for Fuels in Ground Water, Surface Water, and Leachate

    It may be necessary to know other subsurface information to remediate fuels in ground water. Treatability testing to characterize contaminant biodegradability and nutrient content may be needed for any biodegradation technology. A subsurface geologic characterization would be particularly important to characterize the migration of NAPLs. Recovery tests are usually necessary to design a ...

  • Severe Drought and Collapsible Water Storage Tanks and Pillow Bladders

    The U.S. Department of Agriculture's Drought Monitor has recently published information indicating that up to 95 percent of Texas is experiencing either "severe" or "exceptional" drought conditions this year. According to the National Weather Service, Texas experienced the hottest period (June through August 2011) on record in the U.S. In addition, the Lower Colorado River Authority (LCRA) ...

  • Case study – benzene contamination - tank battery, Weld County, Colorado

    Introduction LTE was requested by Devon Energy Corporation (Devon) to remediate residual soil and groundwater impacts at an exploration and production site in Weld County, Colorado. Soil impacts were found from the surface to 24 feet below ground surface (bgs) and were a result of produced water sump and aboveground storage tank overfills. Benzene concentrations in the groundwater were up to ...

    This article is excerpted from 'Pure Water Handbook' published by Osmonics®, Inc. of Minnetonka, Minnesota USA and is printed with permission of Osmonics, Inc. Water treatment can be defined as any procedure or method used to alter the chemical composition or natural 'behavior' of a water supply. Water supplies are classified as either surface water or groundwater. The majority of public or ...

  • Mono provides safe drinking water to the sesemi museum

    In 1831 the Danish Government purchased a plantation in the Akwapim range north of Accra, Ghana. The plantation was named Frederiksgave in honour of the Danish King Frederik VI. In 1850 the site was abandoned and the local people settled in the village of Djabing, around 500 m down the hill. Until 2006, the closest safe drinking water source was a single hand pump -1.6 km further down the hill. ...

  • Residents of a Florida trailer park think their contaminated water made them sick

    Allan Payan lifts a photograph from a shelf inside his singlewide trailer home. The smiling woman in the image has full cheeks and long, thick, brown hair. Caroll Payan, who sits across the couch from him, can't bear to look at the old photo of herself. She has dropped 20 pounds in the past six months, and it shows in her tall, wiry frame. Her green eyes now bulge under heavy lids on a gaunt ...


  • Oil/water separator and oil skimmer companies work together to help power generation facilities

    Power generation facilities depend on oil/water separators to separate oil from its waste water. While oil/water separators are a helpful component to a plant’s wastewater system, oil/water separators traditionally do not provide an efficient method of removing oil once it has been separated from the waste stream. Knowing what his customers were faced with, Dave Goding, president, Mercer ...

  • Sustainable wastewater separation treatment systems coupled with nutrient and water reducing greywater reuse technologies

    Nationally and internationally, pressure is increasing to introduce nutrient reducing, water conserving and recycling measures for sustainable residential and small community water/wastewater systems. Reports of inadequate water quality and quantity are being reported daily. Over the past thirty years the federal government and State of Alaska have invested over 4 billion dollars installing piped ...

  • Site Characterisation in Support of Monitored Natural Attenuation of Fuel Hydrocarbons and MTBE in a Chalk Aquifer in Southern England

    This Case Study Bulletin describes a research project, which was carried out to determine whether monitored natural attenuation was a viable option for managing fuel hydrocarbon contamination in a chalk aquifer in southern England. The research, which was carried out from February 2000 to March 2001, was undertaken by the University of Sheffield on behalf of TotalFinaElf at a petrol filling ...

  • Residential system design

    Rainwater systems can be as simple as placing a rain barrel beneath a downspout or they can be complex – engineered multi-tank systems with pumping stations and automated computer controls for supplying commercial and industrial process applications. Consider that in one installation in the Sumo arena in Japan, rainwater is supplied for flushing toilets and the cistern’s excess ...

  • In situ bioremediation of pentachlorophenol by dissloved oxygen injection

    ABSTRACT: In September of 1982 a faulty valve on a railroad tank car resulted in the accidental release of a wood treating solution containing pentachlorophenol. Subsequent investigations indicated that the wood treatment dip tank had also been a source of soil and ground water contamination. A ground water and product extraction system was installed soon after the rail car release, but after 13 ...

  • Muller + Muller`s lakefront restrooms flush with rainwater

    A pair of highly sustainable comfort stations debuted on Chicago's lakefront over the summer, at 5800 North and 4000 South. Designed by Muller + Muller Architects, the seasonal-use brick structures use natural ventilation, daylighting and low-maintenance materials to minimize their ongoing use of resources. But prime among the pair of buildings' low-impact strategies is the use of captured ...
