A spill near a residential area in Quebec released petroleum hydrocarbons into the underlying groundwater and soil. The accident posed a risk to nearby wells, endangering the local water supply.
PHC contaminants included: Benzene, Toluene, Xylene
The Vertex Approach
Vertex was employed to design and optimize a highly efficient, yet cost-effective in-situ remediation program. A chemical oxidation process was identified as the most suitable. A team of experts proceeded to:
- Acquire all relevant permits
- Analyze treatment parameters across multiple applications (unconfined sand formations, grasslands)
- Inject an oxidant solution of activated persulphate with a hydrogen peroxide activator
Over 30,000L of oxidant solution was effectively distributed through the impacted area using a vertical well process. Remediation objectives for BTEX, F1 & F2, and F3 & F4 were met with no ongoing operation and maintenance costs.
Disruptions for nearby residents were kept to a minimum and nearby structures were not affected by the remediation efforts. A Record of Site Condition was obtained, enabling residential land development to proceed.
