Univar USA, Inc. is a nationwide company that stores, packages, and distributes a variety of chemical products. The Univar facility in Kent has a warehouse, office, dock, and parking areas on an eleven-acre site, surrounded by other commercial and industrial properties.


Beginning in the 1990s, Ecology investigated contamination from waste management activities and accidental chemical releases. Studies showed that soil in two areas of the eastern portion of the site are contaminated with organic chemicals and chlorinated compounds.

Groundwater is also contaminated. Most of the groundwater contamination remains located beneath the property. Some contaminants in the deeper part of the aquifer have flowed north under 212th Street and beneath an adjacent industrial property.


The Department of Ecology issued an agreed order (a legal agreement) requiring Univar to plan and implement a site cleanup. In 2007, Ecology selected the preferred cleanup activities from the Feasibility Study report.

Univar has been implementing the Cleanup Action Plan, which includes:

  • Treatment of contaminated areas using enhanced reductive dechlorination.
  • Monitored natural attenuation for treatment of the down-gradient groundwater plume.
  • Institutional controls to assure long-term protection of human health and the environment.
  • An environmental covenant placed on the property. This covenant is required since contaminants in excess of cleanup standards will remain on the property after the cleanup action.
  • Treatment of the source areas and ongoing groundwater sampling. The sampling shows how much groundwater contamination is still present. The sampling information is also used to assess the effectiveness of treatment, so it can be adjusted as necessary.
