April 9th, 2014 AEL environment 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...

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...

When developing a conceptual site model (CSM), the focus moves from the initial review of background information to the identification of potential contaminants of concern. Investigation into the site’s historical background should identify past site owners and operators, which would identify contaminants likely to be present at the site. For example, if past operations on...

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...

When gathering data for a Phase 2 ESA or other reports through on-site testing or environmental site screening, it is important to note that the results are only as good as the data. On-Site Data Quality & Why It Matters: Inaccurate data means that decisions will be based on erroneous beliefs and a poor site...

The “hidden” and non-homogeneous nature of contamination at brownfield sites provides unique challenges to environmental site assessment (ESA) and clean-up work. What Are The Implications of Brownfield Contamination? Brownfield contamination ignites potential for fatal “flaws” like missing impacted soil or groundwater at a previously determined “clean” site. In order to effectively address the financial, environmental,...
