Developing a Conceptual Site Model- Contaminant Pathways and Receptors
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...

Not Just “Dirt”: Why Does Clean Fill Matter?
The Ontario Ministry of the Environment and Climate Change (MOECC) has identified improperly managed Soil Fill as an important potential contributor to contaminated sites. Soil to be moved from one property (Source Site) to a different property (Receiving Site) must be managed in order to prevent the discharge of a contaminant to the environment that...

Remediation Approach: Removing Arsenic from Water Using Chemical Precipitation
The use of arsenic in agriculture and industry since the early 1900s has increased the concentration of arsenic in the environment. Arsenic can be found in soil, groundwater, and wastewater – often at concentrations that can be harmful if left untreated. Removing arsenic from water is critical. One specific way that arsenic impacts the environment...

Site Screening – Using On-Site Soil Testing To Reducing Uncertainty in Phase II ESAs
When completing a Phase II Environmental Site Assessment (ESA), proper site characterization is essential to the investigation. It is important to gain a clear understanding of site conditions in order for the Qualified Person (QP) to give an accurate report at the conclusion of the ESA.   On-site screening is one strategy that strengthens the...

Understanding A CSM – Finding Data Gaps
When preparing a Record of Site Condition 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...
