This webinar event will detail two field study remediation projects designed to evaluate the effectiveness of in situ chemical oxidation (ISCO) using catalyzed persulfate (PersulfOx™) vs. base-activated persulfate on petroleum hydrocarbons. One study site was impacted by gasoline within a shallow unconfined silty sand aquifer, whereas the second site was fractured bedrock impacted by heating oil.
The field studies were designed to evaluate the two different types of persulfate applied at each site and reagent-specific characteristics including:
Key findings that will also be discussed include:
