Isotope fractionation due to diffusion and sorption of chlorinated hydrocarbons and its implications for identifying reactive processes in aquifer - aquitard systems

Wanner, Philipp ; Hunkeler, Daniel (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2016.

Chlorinated hydrocarbons are anthropogenic contaminants, which are known to be possibly carcinogenic to humans. Although the peak production of chlorinated hydrocarbons in the 1970ties was followed by a dramatic decrease in the subsequent decades, chlorinated hydrocarbons are still frequently detected in aquifer systems demonstrating their long-term persistence. When chlorinated hydrocarbons are...

Assessment of in situ biodegradation of chlorinated solvents in aquifers and constructed wetlands using an integrative approach

Imfeld, Gwenaël ; Hunkeler, Daniel (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2008 ; Th.2069.

Knowledge about biogeochemical processes associated with natural attenuation of chlorinated solvents in the environment is currently limited. Though processes such as sorption, volatilization or dilution may contribute to contaminant natural attenuation, in situ biodegradation is the only process leading to destructive removal of contaminants. However, the distribution of hydrological and...
