A historic chlorinated solvent spill from a former dry cleaning facility had caused contamination of the soil and groundwater below the site. With a high seepage velocity (approx. 17 m/year), the contamination was found to be migrating towards a local stream, posing an unacceptable risk to the environment. REGENESIS was asked by Environmental Consultant ABO NV to provide a solution to treat the plume onsite and stop its migration over the site boundary.
