4,700 ppb of benzene was present in the groundwater at the 60,000 ft.3 site. Treatment application consisted of chemical injection through a series of direct push points of Klozur® (Sodium Persulfate) followed by PermeOx® Plus over a five-day period.
Benzene concentrations were reduced from 4,700 ug/l to 3.3 ug/l. Down-gradient wells outside the active injection area also showed a significant reduction.
Successful treatment of petroleum contaminated soil and groundwater at the site of a former leaking underground storage tank using PermeOx®.
In situ treatment to an active petroleum service station site in the coastal plain of Florida, USA
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.
The selected remedy, soil mixing using in situ chemical oxidation (ISCO) combined with in situ solidification and stabilization (ISS) was used to destroy contaminants while stabilizing soils
Site Closed Following a Single Application of Klozur® SP and Hydrated Lime.
