Industrial activities at a former industrial site undergoing redevelopment in Northern Italy resulted in chlorinated solvent groundwater contamination requiring remediation. Contamination consisted of chlorinated constituents 1,2-Dichloropropane at 9 μg/L and 1,1-Dichloroethene at 1 μg/L.

However, the aquifer also showed a marked concentration of a competitor electron acceptor (approx. 1,000 μg/L sulphate). Due to very low target contaminant concentrations and difficult geology, physical and chemical remediation methods were rejected, and in-situ anaerobic bioremediation using REGENESIS’ 3-D Microemulsion^® was deemed the most cost-effective approach.
