The rail yard site in Nijmegen, Netherlands has been subject to contamination via leaks, spills, and filling losses of hydrocarbon fuels over the years. Despite previous remediation attempts there remained residual TPH contamination. Following a successful bench test, a full-scale remotely controlled injection unit was used for implementation of alkaline activated Klozur® persulfate. The reduction of the TPH levels achieved the remedial goals in both the bench and fieldwork.Klozur® SP
The Mattoon Former Manufactured Gas Plant (MGP) site was historically operated using a method of extracting oil from coal for use in residential lighting and heating before natural gas was available. One of the waste products of this process is coal tar, which is a mixture of volatile organic compounds (VOC) and polycyclic aromatic hydrocarbons (PAH). XDD designed and implemented full-scale treatment of VOC’s and PAH’s using Alkaline Activated Klozur Persulfate. XDD used a combination of permanent injection wells installed along with temporary direct push injection wells to implement the ISCO treatment.Klozur® SP
Comparison of In Situ Chemical Reduction (ISCR) to Enhanced Reductive Dechlorination to treat trichloroethene in an aerobic aquifer.ELS™ Microemulsion Chlorinated Solvents
ORIN successfully remediated the site by injecting Klozur® (sodium persulfate) and PermeOx® Plus chemistry through a series of direct push points over a five-day period.Klozur® SP PermeOx® Ultra BTEX
Specialty Earth Sciences, LLC was contracted to remediate a site that was impacted by residual coal tar by utilizing chemical oxidation methodologies.Klozur® SP BTEX
EcoVac Services implemented SURFAC® and ISCO-EFR® at this site to remove SPH and reduce BTEX concentrations below the site’s CALs.Klozur® SP BTEX
Hazardous soils at two former locations of a manufacturing facility were treated by ex situ chemical oxidation, in order to meet the treatment standards for a nearby landfill as a non-hazardous waste.Klozur® SP Petroleum Hydrocarbons Pesticides & Herbicides
Specialty Earth Sciences, LLC was contracted to provide the rapid reduction of BTEX hydrocarbon mass present within impacted soils and groundwater at the site.Klozur® SP BTEX
JAG Consulting Group, Inc., implemented a peroxide activated Klozur® (sodium persulfate) groundwater treatment at a UST site.Klozur® SP BTEX Oxygenates
