In the fall of 2016, the Rentokil Superfund Site was buzzing with large yellow earthmoving machinery.  Arcadis, the environmental contractor for Rentokil, was preparing the ground surface for a large thick plastic cap layer and slurry wall installation project at the Richmond, VA site. The purpose of the plastic cap layer and slurry wall is to control exposures to impacted soils and prevent the migration of groundwater contaminated by pentachlorophenol (PCP). These actions were the result of a cooperative agreement between DEQ and EPA to support regulatory oversight of this Superfund project.

In early summer 2017, the plastic cap layer was covered with soil and native grasses were planted. Monitoring wells will be installed north of the slurry wall to detect any leaks before contamination reaches the North Run Creek. Monitoring will continue forever, or as long as waste is contained at the site.

The Rentokil property was used for wood preserving operations between 1957 to 1990 and is currently owned by Virginia Properties Inc., a Rentokil Initial Company. During this period, wood preserving chemicals, including PCP, were released to the environment. It was declared a Superfund site in 1989. Early actions conducted in the 1990’s at the property included fencing the property, removing site structures, excavation and off-site disposal of hazardous waste, installing a plastic cap layer and slurry wall in the former main wood treating area, and pumping and treating groundwater under the property.

This remedial action, along with earlier remedial actions, was completed in a manner that allows for the property to be reused for industrial or commercial purposes. Until the property is redeveloped, the site will be mowed and remain fenced to preserve the property condition.
