Background

Located in Central Canada, the site was a former industrial area impacted with petroleum hydrocarbons. Upon learning the history of the site, which included usage for firefighting training and fabric coating, the environmental service contractor, In Situ Remediation Services Limited (IRSL), tested the groundwater for the presence of PFAS compounds and detected PFOS at 1,450 ng/L and PFOA at 3,260 ng/L. The contaminants, including the hydrocarbon, were located in a shallow area of an unconfined, silty sand aquifer with relatively high groundwater flow. The source had been excavated and IRSL was tasked with treating the remaining TPH to regulatory standards.
