MECX performed the first active oxidant in-situ chemical oxidation (ISCO) application pilot test at a former chemical plant located in Trento, Italy.
Release of oils and PAHs from a petroleum processing facility soil pit caused extensive contamination at the site which was migrating to a river. A recirculation system used Klozur® (activated sodium persulfate) as the ISCO technology of choice. The remediation program also included the recirculation of fluids from the extraction well to enhance the desired groundwater flow and control chemical dispersion through the target treatment area
Dissolved concentrations of all target analytes were measured after 4 weeks and found to be below action levels of less than 50 ug/l.
