  • 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 ...

  • Potable Water Storage Tanks Need Mixing

    There are more than 50,000 municipal water systems in the United States and most of these systems rely on water towers, above-ground, and below-ground tanks to store their treated potable water. Many operators rely on mixing via normal cycling of water in and out of the tank to limit water age and deterioration of disinfectant chemicals. This reliance on "passive mixing" is not enough in most ...

  • 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 ...

  • 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 ...

  • WPL’s easy to install diamond sewage treatment plant case study

    If you are lucky enough to be involved with a building project in the beautiful countryside of Great Britain, one thing you will find most properties have in common here is that they are likely to be off-mains drainage. When involved with an off-mains building project, it is important that you do know where your wastewater goes and what happens to it, usually by means of a domestic sewage ...

  • CH#955 - Fuel Remediation, Difficult Location

    SITE OWNER: A Petroleum Jobber SITE SURVEY: Site and geological surveys had revealed a contaminated area down a gradient from the existing fuel tanks. If was further determined that the contamination was not from the existing tanks through precision testing. The borings described the contamination as resting between the 14 and 20 foot level below the ...

  • 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 ...

  • Risk 101 & Remediation Design

    Risk Assessment is the basis for almost all of our designs. Perceived risk is the basis for the rest of the designs. A good remediation design must incorporate the concentration goals for that site and the designer must know how those goals were set. In order to know how those goals were set, we all must have a basic understanding of Risk Assessment. Not just the numbers, but the methodology that ...
