Feasibility Study on PFAS Remediation for Environment Canada

Oil Disposal Pit, Canadian Forces Base

Client: Environment Canada’s Emergencies Science and Technology Section (ESTS)
Location: Cold Lake, AB
Industry: Military

Project Overview:
In 2012, SCG Remediation Services was commissioned by Environment Canada’s Emergencies Science and Technology Section (ESTS) to conduct a feasibility study on the remediation of per- and polyfluoroalkyl substances (PFAS) in contaminated groundwater. The study aimed to evaluate the effectiveness of granular activated carbon and ion exchange media in removing PFAS from groundwater.

Key Challenges:

  • PFAS Contamination: PFAS are persistent environmental pollutants, and their removal from groundwater is technically challenging.
  • Efficacy of Treatment Media: The study required a thorough evaluation of the selected treatment media’s ability to remove PFAS effectively.

Technical Execution: SCG executed a comprehensive feasibility study with the following steps:

  • Design and Manufacture: Developed a custom water treatment system specifically for PFAS-impacted groundwater.
  • Well Network Installation: Designed, supplied, and installed the necessary well network, including pumps, piping, and infrastructure, to recover contaminated groundwater.
  • System Operation: Successfully extracted and operated the groundwater treatment system, ensuring optimal performance and data collection.

Conclusion: The feasibility study confirmed the efficacy of the pump and treat system using an adsorption-based approach with granular activated carbon and ion exchange media. The study met all guidelines for treated water, including the removal of total suspended solids (TSS), metals, hydrocarbons, and PFAS.

Results: Confidential

Project Duration: Unspecified

Conclusion: This feasibility study underscores SCG Remediation Services’ capability in designing and implementing effective water treatment solutions for complex contaminants like PFAS. The project provided critical data supporting the use of advanced adsorption media in groundwater remediation, demonstrating SCG’s expertise in addressing environmental challenges in the military sector.
