Following a successful field pilot test, a full-scale PetroFix remediation was designed and implemented at seven locations to treat petroleum hydrocarbons (PHCs). Three locations targeted source areas onsite while the other four locations addressed PHC contaminants that had migrated offsite. PetroFix was applied through direct push injection in all areas. One of the onsite locations contained very high PHC concentrations in soil and groundwater, with suspected light non-aqueous phase liquids (LNAPL). These conditions were beyond a cost-effective treatment range for PetroFix, requiring a combined in situ chemical oxidation (ISCO) and enhanced aerobic bioremediation pretreatment step utilizing PersulfOx and ORC Advanced, respectively.
