Assessment of bioremediation potential and monitoring of biological reductive dechlorination in sites contaminated with chlorinated ethenes

Christof Holliger, Pierre Rossi, Sonia Estelle Tarnawski

Chlorinated ethenes (CEs), such as perchloroethene (PCE) and trichloroethene (TCE), are one of the most common class of groundwater contaminants. Aquifers are considered nowadays as dynamic ecosystems, showing multiple interactions between the physical, ch ...

Full-waveform GPR inversion to assess chloride gradients in concrete

Eugen Brühwiler, Alexis Kalogeropoulos

The spreading of deicing salt on roads during winter and the consequent migration of chloride ions within concrete exposes structures reinforcement to corrosion. Reinforcement corrosion is problematic because it reduces the structure's load carrying capaci ...

Multidisciplinary approach for evaluation of the complete removal of chloroethenes in contaminated aquifer

Christof Holliger, Pierre Rossi, Sonia Estelle Tarnawski, Martina Praveckova

Chlorinated ethenes (CEs) pose a long-lasting risk for humans and the environment. Nowadays, they are the major groundwater contaminant worldwide and are of particular concern since they form a dense non-aqueous phase liquid (DNAPL). Reductive dehalogenati ...

An advanced calibration process for a thermo-hydro-mechanical triaxial system

Lyesse Laloui, Alessio Ferrari, Ali Seiphoori

This paper presents an innovative double cell triaxial system developed for better understanding of the complex thermo-hydro-mechanical behaviour of soils. In addition to the conventional triaxial mechanical testing, the equipment is aimed to perform sucti ...

A colorimetric CO sensor for fire detection

Nico de Rooij, Danick Briand, Kay Severin, Jérôme Courbat, Mirela Pascu

We report on a colorimetric carbon monoxide (CO) sensor based on a rhodium complex. The sensor relies on changes in the light absorption properties of the chemochromic reagent when exposed to the gas. Its optical properties in solution and in a polymeric m ...

Anaerobic degradation of vinyl chloride in aquifer microcosms

Christof Holliger

The anaerobic degradation potential at a chloroethene-contaminated site was investigated by operating two anoxic column aquifer microcosms enriched in iron(III). One column was fed with vinyl chloride (VC) only (column A) and one with acetate in addition ( ...

Photo-Fenton degradation of resorcinol mediated by catalysts based on iron species supported on polymers

César Pulgarin, Félicien Mazille

Novel Fe supported catalysts were prepared by immobilizing iron species on commercial polyethylene via three different methods: (1) acidic pre-treatment of the polyethylene followed by impregnation in aqueous Fe(NO3)(3), (2) TiO2 photo-catalytic pre-treatm ...
