When we talk about forensics, we’re usually talking about
investigating events in the past: analyzing DNA evidence found at the scene of
a crime, reconstructing a traffic accident to discover the cause of a collision,
assessing accounting systems to determine culpability in the aftermath of fraud,
or sampling a groundwater plume to determine the source of contamination; ultimately,
the analysis is occurring ex post facto. So instead of reacting to events, what if scientists sought
to anticipate the needs of their field? For example, what if scientists began applying
the analytical tools we currently have with an eye toward future litigation in
the environmental arena?
In the video below, Dr. Frank Dorman,
Professor of Biochemistry and Molecular Biology at Penn State, discusses the
application of one such analytical tool, multidimensional gas chromatography
time of flight mass spectrometry (GC-TOFMS) to hydraulic fracturing. His talk
highlights both the challenges as well as the advantages of separation science
in the context of contaminated water and forensics and its applicability to the
courtroom. Dr. Dorman demonstrates the visualization capabilities of GC-TOFMS
that allow it to make distinctions as to the source of the contamination
(wastewater from conventional oil and gas or Marcellus Shale gas), and
ultimately who is the responsible party.
