Regenesis webinar event will detail two field study remediation projects

Regenesis's 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 purpose of the field studies was to evaluate the two different types of persulfate applied at each site and reagent-specific characteristics including:

  • Material delivery into the treatment area
  • Subsurface distribution
  • Reagent persistence
  • Treatment effectiveness
  • Potential for rebound  

Key findings that will also be discussed include:

  • Distribution of oxidant solution varies by injection method
  • Buffering reactions appear to have a significant impact on pH-based activation
  • There is limited correlation between laboratory and field test
  • Catalyzed persulfate (PersulfOx) produced significantly better treatment results than base-activated persulfate
