    High-Mass Petroleum Hydrocarbons Treated to Achieve Closure

    Case Study Highlights:

    • PersulfOx injected into subsurface during 3 treatment rounds, sequenced ±2 months apart

    • Toluene reduced by an average of 94% and below the toluene Site-Specific Target Levels (SSTLs) in all 5 performance monitoring wells

    • Toluene remains below its SSTL following the injection of PersulfOx

    petroleum remediation

    A former US electric service company reported a release during a UST removal completed at the site in 1988. Previous remediation by others included aggressive fluid vapour recovery events completed from 2004 to 2008 and from 2019 to 2020 to address the release, along with groundwater monitoring. Despite these efforts, high concentrations of petroleum hydrocarbons (PHC) remained. Following years of remediation, the final selection and successful application of PersulfOx® effectively reduced high concentrations of toluene in groundwater below the site cleanup goal. The remediation achieved the site target cleanup objectives and received regulatory closure for the decades-old release incident.
