Understanding A CSM – Finding Data Gaps
When preparing a Record of Site Condition (RSC) under O.Reg. 153/04, the investigative team must create a conceptual site model, or a CSM. The CSM clearly articulates the project team’s (including Qualified Person, project engineers, field scientists, and others) understanding of the site’s environmental system framework, impacts and associated potential risks. One aspect of the…

Remediation Approach: Screening and On-Site Testing at Remote Sites
On remote sites, like those in Canada’s Far North, the cost of traditional remediation can be astronomical. Because these sites are often beyond the access of landfills, soil transport and disposal can make traditional “dig-and-dump” remediation too expensive to pursue. For this reason, AEL believes that remote sites are often ideal locations for choosing alternative…

Remedial 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…

Understanding A CSM – Using On-Site Testing to Strategically Fill Data Gaps
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…

Case Study: Changing Course During a Phase 2 ESA
New information collected on site during a client’s Phase 2 ESA, resulted in the need to adapt their sampling plan.

Real-Time Results with the XRF
When accurate real time screening results are collected during an environmental site investigation or remediation, the team gains an invaluable tool for directing field work. The use of on-site testing ensures that adequate information is collected in order to make confident decisions about site conditions and next steps. On-site soil testing tools such as ultraviolet…
Remediation Approaches – In Situ Chemical Oxidation (ISCO), Part 1 featured image
Remediation Approaches – In Situ Chemical Oxidation (ISCO), Part 1
Is ISCO a good choice for your site? Many contaminants and site conditions are difficult to treat with conventional remediation technologies such as soil vapor extraction, air sparging, bioremediation, or pump and treat. In addition, conventional technologies are often costly and time-consuming. For the past 20 years oxidation has become a common alternative for in…

Remediation Approaches – In Situ Chemical Oxidation (ISCO), Part 2
When is ISCO a good fit for an environmentally impacted site? In situ chemical oxidation is not applicable to all contaminants or to all situations. Considerable research has been conducted and is continuing to determine the optimal contaminant–oxidant match. The application of in situ chemical oxidation is a step-wise procedure involving: The first three of…

No “Turkeys” Here! AEL Volunteers At Local Food Bank
AEL is proud to support several local community organizations. This week, we visited Eden Food Bank in Mississauga and helped them to make over 250 portions of cooked food for clients to take home. This ensures that larger donations (like 12 turkeys) reach many families and are already prepared for them as some clients don’t…
