If you have read any of our previous blog posts, attended any of our seminars or webinars, or read about how we have solved soil and groundwater problems, you know we place a lot of emphasis on getting each step right. And getting each step right begins with the collection of environmental data in the field. In fact, last year, one of my colleagues, Clifford Lawton, wrote what amounted to a treatise on the importance of proper sample collection (see Soil and Groundwater...
Read MoreRegulating Nanoscale Materials
Chemical substances in Canada are regulated under the Canadian Environmental Protection Act, 1999. Substances are in one of two groups – existing or new. There are about 23,000 existing or current substances on the Domestic Substance List (DSL). In 2006, the 23,000 substances of the Domestic Substances List were “categorized” according to the potential risk they posed to human health and the environment. This set the priority by which substances were to be assessed under...

With the mandatory cap and trade system in place, it will build on the...
Read MoreSeven Common, Environmental Site-Assessment Mistakes
In our last blog, I asked Dr. Michael Sklash questions relating to TCE – how it behaves in the environment, what to do if you had a release, etc… While Mike did not mention it in our interview, a great number of our projects (regardless of the contaminant) begin with a peer review of the existing work (investigation, remediation, etc). So, I asked Mike to share, based on his experience, the most common mistakes he has seen over the last 27 years when doing peer reviews....
Read MoreTCE Found in London, Ontario, Groundwater: What you need to know about TCE
On March 10th, CTV reported that elevated levels of trichloroethene (TCE) were found in groundwater along Brydges Street in London, Ontario. It is not currently known if there is any immediate health risk to the local community. As we understand, indoor air will be tested to assess the potential for vapour intrusion in homes (read more about vapour intrusion). The current London issue aside, TCE has been amongst the most common chemical contaminants in soil and...
Read MoreProtecting the Great Lakes – Will This Act Help?
It’s back. The “it” is the Great Lakes Protection Act, and, in February 2015, the Ministry of the Environment and Climate Change announced that the Act had been reintroduced. For those of you who have been following this issue, you know that the bill was first introduced in June 2012, but it didn’t get much traction. So what’s changed? And why is this legislation again being considered? If I were to speculate, based on recent environmental news stories, I would say that...
