• Remediation of TPH at a Rail Yard in the Netherlands with Alkaline Activated Klozur® Persulfate Achieves Remedial Goal

  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.

• ISCO-ISS For Remediation of Source Area Soils at a Former MGP Site in Denmark Achieving Several Site Goals

  The approach was designed to remove the lower molecular weight compounds, which are the more soluble and mobile fraction of the contamination, via chemical oxidation while cementing the remaining higher molecular weight fraction of the tar in place. The addition of cement was also intended to activate the Klozur SP by generating alkaline conditions, significantly improving the kinetics of the ISCO reactions.
