  • Spolchemie site remediation and NanoRem field site application

    Site Remediation The Spolchemie site was chosen as one of the NanoRem case study sites, to test two types of nanoparticles (NPs) (zerovalent iron - nZVI and iron oxide NPs) for in situ remediation of BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) contamination. Nanoremediation was seen as an opportunity to enhance the in situ biodegradation of the BTEX contaminants and to reduce the ...

  • Geostatistical modelling of ground conditions to support the assessment of site contamination

    The pattern of ground contamination across a site depends on the historical pattern of contaminant releases at the surface and the redistribution and the fate of contaminants below the surface. Using these concepts a new site assessment approach (assessment modelling) is proposed based on the development of three stochastic models: a model of the physical structure of the ground materials beneath ...

  • Legionnaires’ disease (Legionella pneumophila)-sometimes deadly, sometimes not!

    More than 90% of Legionella cases are caused by Legionella pneumophila, a bacterium that thrives in warm to hot water.  Pipes, tanks, faucets, showerheads, and hot water heaters are ideal breeding grounds for L. pneumophila.  Since infection with Legionella occurs through inhaling the bacterium, any activity in which contaminated water can be misted and subsequently inhaled can lead to ...
