Klozur® One Application Destroys over 99% of Trichloroethylene in Five Weeks at a Former Manufacturing Facility in The Netherlands

Rapid results were required for the redevelopment of the site to a residential area. After 4 weeks of injecting Klozur One through fixed wells, TCE concentrations were below remediation targets.

Type of Site

Former Manufacturing

As a blend of sodium persulfate with built-in activation chemistry, Klozur One provided powerful oxidation capacity as a “ready to use” product suitable for this highly contaminated treatment area. Each batch of injectable solution was mixed together and then subsequently applied to the subsurface through existing injection wells. Weekly monitoring of 10 wells showed reductions of TCE below remediation targets after 4 weeks.
