Manufacturing Facility, Europe
The subject site has been used for the manufacture of industrial switchgear assemblies and warehousing since the 1970s. A subsurface investigation revealed a highly localized plume near WS10 with significant groundwater concentrations of trichloroethene (TCE) at 260 parts per million (ppm) along with its breakdown product cis-1,2-dichloroethene (DCE). A site specific target level (SSTL) was established for TCE (1.0 ppm) and remedial action began with an in-situ injection of Hydrogen Release Compound (HRC®). The product was considered an effective approach since it did not require long-term maintenance and produces a limited amount of waste.
