Innovative reactive barrier technologies for regional contaminated groundwater

At many industrial sites inadequate waste disposal, leakages and war damages have led to severe groundwater contamination on a regional scale. Standard hydraulic groundwater remediation methods, such as pump-and-treat, in most cases do not lead to satisfactory results, due to the persistence of organic contaminants and the resulting very long...

On diffusive mass-transfer limitations in relation to remediation of polluted groundwater systems

Limited diffusive mass transfer is one cause for stagnant groundwater remediations. We characterise the diffusive mass transfer process as a three stage cyclic process of mass transfer into and out of stagnant or immobile zones. The first stage is the contamination stage, where net inward diffusive mass transfer happens and the last stage is the...
