SITUATIONAL SUMMARY

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

RESULTS

Dissolved concentrations of all target analytes were measured after 4 weeks and found to be below action levels of less than 50 ug/l.
