  • Comparison of different approaches for odour impact assessment: dispersion modelling (CALPUFF) vs field inspection (CEN/TC 264)

    Odour impact assessment has become an important environmental issue. Different approaches can be used in order to evaluate the odour impact on receptors, and therefore to regulate it. Among the different possible regulation approaches, the use of dispersion modelling is suggested or required by several national or regional legislations. The wide diffusion of this approach is probably due to the ...

  • A Monster Pipe Demands Monster-Size Inspection Approach

    From a purely visual perspective, some pipeline inspections are more awe-inspiring than others. This is especially true when everyone involved describes the pipe diameter as “monster-size,” clocking in at 210 inches in diameter. A challenge of this magnitude requires fresh thinking from an inspection approach, especially when the subject pipe is so critical to the lifeblood of the ...

  • 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 ...
