Site background
Univar is a global company that stores, packages, and distributes chemical products. The 11-acre Kent facility has a warehouse, office, bulk storage, repackaging, and parking areas. It is surrounded by other commercial and industrial properties.
From 1974 to 2007, Univar was considered an active dangerous waste management facility. However, it was not subject to permitting requirements under the Resource Conservation and Recovery Act until hazardous waste regulations became effective in 1980.
Contamination
In 1994, studies showed evidence that soil and groundwater was contaminated with solvents and chlorinated compounds. Most groundwater contamination is located under the site, but some flowed north under 212th Street and an adjacent industrial property. No drinking water wells are located in or near the site.
Cleanup process
Since 2009, Univar has been implementing a cleanup action plan:
- Groundwater treatment via enhanced reductive dechlorination, a process that uses special bacteria to "eat" the contaminants.
- Groundwater monitoring. The site is tested regularly to see if pollutants are breaking down into less harmful chemicals.
- Ongoing treatment and sampling.
- Site use controls, which restricts the property to industrial use via an environmental covenant.
