Numerical modeling of field scale application of ground silicate minerals for groundwater pH buffering

David Andrew Barry, Christof Holliger, Alessandro Brovelli, Elsa Marina Lacroix

Recently, it was shown that ground silicate minerals are a potentially suitable pH buffering material for contaminated soils undergoing acidification, for example due to acid mine leachate and coal pile runoff infiltration, as well as during the degradatio ...

Evaluation of silicate minerals for acid neutralization during bioremediation of high concentrations of chlorinated ethenes

Louise Gilbert

Chloroethenes are the most prevalent groundwater contaminants in developed countries. They accumulate in the environment as a dense non aqueous phase liquid (DNAPL) which acts as a long term source of contamination. Enhanced in situ anaerobic bioremediatio ...
