摘要
Metal has been degreased since the late forties at the Brabant site in The Netherlands, located along a canal. These activities have resulted in soil contamination with trichloroethene (TCE) and trichloroethane (TCA). Within the framework of the Dutch research programme NOBIS, the contamination and soil conditions were thoroughly investigated, and the combined dechlorination of ethenes and ethanes was demonstrated in batch experiments. A full-scale pilot system with infiltration and extraction screens was built at a depth of 10-20 m below ground level. Currently, the microbiology is stimulated through the infiltration of an electron donor thus leading to lower redox conditions and dechlorination of the target compounds.
