Perchloroethylene (PCE) contamination was discovered in the groundwater under a large industrial unit in Falkenberg, Sweden. The contamination was shown to have migrated offsite under neighbouring residential properties downgradient. A remediation strategy was implemented to reduce the risk to human health and downstream controlled waters. An in situ remediation strategy was chosen to minimise the disturbance onsite and allow use of the facility to continue.
WSP commissioned contractor RGS 90 to undertake the application of 3-D Microemulsion® (3DMe®) into the groundwater under the factory. The self-distributing properties of 3DMe allowed the number of injection points to be minimised, reducing the amount of coring required through the building’s concrete floor slab and reducing the cost of the project.
