Site Investigations: What Are You Looking For?

“… there is a very strong argument to be made for the intelligent investigator who attempts to understand what they are likely to find on a site and why — someone who brings value to the process. Asking “what am I looking for?” or perhaps more cautiously worded “what am I probably looking for?” is key to a successful sampling and testing plan…”

Ontario’s Revised Brownfield Regulation: SNAPSHOT AT THE HALF-YEAR MARK

With 6 months under its belt, Ontario’s amended Record of Site Condition (O. Reg. 153) to the July 2011 Standards appears to have made a relatively smooth transition from policy to practice. From an analytical laboratory perspective, we continue to field some common questions from our environmental consulting clients. Here are some of our “Top Ten” Q&A (in no particular order).

Best-Practices for Soil Sampling for Volatile Parameters

Improper sampling techniques for volatile organics can lead to seriously compromised test results. Volatile parameters are by their very nature volatile – meaning they vaporize easily. Significant vapor losses can occur during both field sampling and in sample transfer steps that occur in the lab if adequate care is not taken.

It has been estimated that the losses of volatile organic compounds can be as high as 90% by the time the samples come to the laboratory for some samples if they are merely collected in glass containers with Teflon-lined septa. For this reason, a better approach is needed.

After a wonderful 5-year run, we are retiring our biannual Testmark Newsletter and replacing it with Elements, a slimmed-down biannual bulletin aimed at providing technical information and updates for our clients. In an internet-based age susceptible to information overload, we feel there is value in trimming the fat and presenting the facts. We hope you enjoy the read!
