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 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…

What Is Environmental Risk Assessment?
Despite their best efforts to ensure that their properties are clean and free from environmental impacts, landowners occasionally find (through a Phase II ESA) that their property has some kind of contamination in the soil or groundwater. Their property is no longer compliant with O. Reg. 153 and they have environmental liability that needs to…
