Environmental forensics investigations sometimes require the determination of which contaminants came from where and how much is from each of the sources present on the site. This is called source apportionment and is a rapidly growing field in environmental litigation and environmental forensics. It is a field...
I was flying back from a conference near Hartford a couple of weeks ago and realized that I had become a victim to compounding conservatism. How is compounding conservatism in risk assessment related to air travel? Well, let me tell you a story.
In the first post of this series, I described the basis for how we became involved in determining a method for the detection of a natural, biogenic source of toluene. In this post, I describe how the process works and provide some thoughts on how to conduct an investigation.

As part of that role, I pored over data every evening, often long through the night to be able to communicate results to regulators and Nexen management and to put together the next day's...
A little under a year ago, Chemistry Matters provided an all-day legal sampling seminar on best practices, requirements and techniques for legal sampling.
During the months before the INEF 2016 conference, I was thinking about my talk on environmental forensics. I feel like I “do” environmental forensics on most of my projects, even the ones that are not litigation based, so I was asking myself “What is environmental forensics?”.
