Environmental Forensics – Redux

While we spent about two hours putting all of this into context at our recent seminar, here’s one of the most important take aways from our Environmental Forensics seminar:

 Remediation decisions, court decisions, the decision to do more investigation…are not based on what is actually in the subsurface; decisions are made based on the Conceptual Site Model (CSM).

It doesn’t matter if you are dealing with a petroleum release, a TCE release, trying to better understand a potential vapour intrusion issue, or differentiating between various sources of releases…if you don’t have a robust CSM you could be headed for years of frustration.

This “robust” CSM should include everything you know about a site, including the following:

  • Site history
  • Hydrogeologic information
  • Release source and timing
  • Physical and chemical properties of the release
  • Contaminant fate and transport
  • Distribution of chemicals
  • Risks/exposure pathways/receptors

…and, of course, the level of detail you uncover in each of the above will add more and more clarity to your CSM.

If you would like to learn more about how you might use forensic techniques to get your site investigation or remediation back on track, contact Dr. Michael Sklash (msklash@dragun.com) at 519-979-7300, ext 120, and ask him about our Peer Review.
