Over the years, we have successfully treated thousands of sites impacted by hazardous contaminants around the globe. To search our case studies, please use the filters provided at the right or enter a search term such as type of site (e.g. dry cleaner) or location (e.g. Florida).
An initial treatability test followed by field application demonstrated that a low dose of MetaFix was successful in treating soils highly contaminated with chromium to below a stringent remedial goal of <1 mg/kg.
MetaFix® ReagentsXDD designed and implemented full-scale treatment of VOC’s and PAH’s using Alkaline Activated Klozur SP at the Mattoon Former Manufactured Gas Plant (MGP). XDD used a combination of permanent injection wells installed along with temporary direct push injection wells to implement the ISCO treatment.
Klozur® SPThe 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® SPThis report summarizes field observations, analytical results for soil cores and "crust" analyses on soil cores collected approximately 60 days after treatment. In addition, it presents the data associated with the Variance requirements associated with the use of the material.
ISGS® Technology Chlorinated Solvents PAHsRapid 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.
Klozur® One Chlorinated SolventsSuccessful treatment of petroleum contaminated soil and groundwater at the site of a former leaking underground storage tank using PermeOx®.
PermeOx® Ultra and PermeOx® Ultra Granular BTEXThe first full-scale application of EHC® Reagent into a flow-through reactive zone was installed in 2005.
EHC® ISCR Reagent Chlorinated SolventsFollowing a truck accident on one of the main motorways in northern Italy, about 3,000 L of 1,2-dichloropropane was released into the ground, causing an immediate contamination of the soil and groundwater. 55,000 kg of EHC® Reagent was injected into a triangular grid of 42 injection points from one to six meters bgs.
