In-situ Technology for Clean up of Halogen Contaminated Sites - Process West case study
Halogenated volatile organic solvents are found in the soil or ground-water at many former and active industrial sites. Fortunately highly effective remediation technologies are available to restore these former brownfields to a healthy state. The range of technologies includes the traditional approach where the contaminated soil is excavated and the volatile halogenated contaminants are ...

The use of microbial gene abundance in the development of fuel remediation guidelines in polar soils
Terrestrial fuel spills in Antarctica commonly occur on ice‐free land around research stations as the result of human activities. Successful clean‐up of spills requires appropriate targets that enable contaminated sites to be signed off as no longer posing environmental risk following remediation. These targets are based on knowledge of the impacts of contaminants on the soil ecosystem and on ...

Using expectations of gain to bound the benefits from contaminated land remediation
Current risk-based decision-making techniques for prioritising contaminated land for clean-up have been criticized within Hungary for their failure to consider remediation benefits. A cost-benefit or risk-benefit approach is required to ensure that scarce resources for remediation are used efficiently. Problems arise because the credibility of non-market valuation information in Hungary is low, ...

Another step towards making mercury history
econ industries is proud to announce the next project towards making mercury history: a delivery contract for a VacuDry® Unit going to India. A VacuDry® 3 000 plant will be deployed to clean-up mercury contaminated soil from a former factory. Due to the location of the factory and strict environmental regulations, an on-site remediation with highest cleaning efficiency was requested. The ...

Case Study: Basford Gasworks Remediation Project, Nottingham
The soils washing installation now owned and operated by HBR was formerly used by Kinatex Heijmans Joint Venture to process contaminated soil at the Basford Gasworks site. The project was the first major land based application of soils washing technology in the UK with in excess of 150,000 tonnes of soil successfully processed. Treatability Phase In the autumn of 1996, LHJV were contracted by ...

London 2012: Legacy or Liability?
After spending hundreds of millions of tax payers’ money on a high profile ‘clean-up’, it has become clear that the 2012 Olympic Park actually remains classified as a contaminated brownfield site. Documents show that the whole area is to have as little as 2 feet (60cm) of “clean” material placed on top of a warning marker layer of orange plastic fabric sheeting, of a type called Terram 1000, ...

Chlorinated VOC Groundwater & Soil Remediation - Case Study
Summary Burns & McDonnell was retained to perform soil and groundwater remediation of chlorinated volatile organic compounds (VOCs) such as perchloroethylene and trichloroethylene (PCE and TCE) at a warehouse facility in Dallas. A historical spill of the chlorinated VOCs behind the warehouse building resulted in the contamination of soil in the immediate area and shallow groundwater leading ...

Enhanced Bioremediation
Introduction Enhanced bioremediation is a process in which indigenous or inoculated micro-organisms (e.g., fungi, bacteria, and other microbes) degrade (metabolize) organic contaminants found in soil and/or ground water, converting them to innocuous end products. Nutrients, oxygen, or other amendments may be used to enhance bioremediation and contaminant desorption from subsurface materials. ...
