Remedial Approach Selection – Giving a Thoughtful Evaluation of Strategies featured imageRemedial Approach Selection – Giving a Thoughtful Evaluation of Strategies
Not every remedial approach will work on every site. Certainly not every remedial approach is ideally suited for every site. AEL takes a careful approach to evaluating and selecting remedial strategies that are matched to the client’s specific goals for the site. When a Phase II ESA finds impacts above the allowable limit on a…

The Triad approach is a set of three strategies, supported by the US EPA, which is widely recognized as the proven modern standard for characterizing and remediating impacted sites. While Canadian regulation does not specifically rely on the Triad approach (although it may introduce similar regulation at some point), Canadian best practices do favour the…
