FINGERPRINTING METHODS FOR SOURCE IDENTIFICATION,
AGE-DATING AND IMPROVED REMEDIATION ACCURACY:
Session One, Part 2: Chiral Fingerprinting and Signature chemicals

Learn up-to-date fingerprinting methods for litigation support,
as well as improving remediation accuracy

Get Answer to Chemical Fingerprinting:

Environmental forensics and chemical finger printing identifies the type and source of contamination. It is critical for both remediation and litigation. It involves all aspects of site characterization and it requires an accurate conceptual site model.

In most cases involving petroleum or petrochemicals we usually start with a basic GC/FID chromatogram as a screening tool for characterization. From there, an investigation may involve chemical ratios, GC/MS precision identification and quantification, or stable isotope analysis.

Gain an understanding about identifying contamination sources
for both remediation and litigation purposes.

Discover additional procedures for analyzing and identifying a given suite of chemicals. Learn to confidently select and defend a forensic technique or petrochemical fingerprint that give clues regarding the origin of petroleum contamination in the subsurface.

Part Two will cover:

Signature Chemicals:

  • Understanding signature chemicals
  • Method principle and steps
  • How to identify and use signature chemicals
  • Applications in source identification, age-dating and estimating contributions to commingled plumes
  • Signature chemicals specific use for investigations of chlorinated solvents and 1,4-dioxane
  • Examples from real case studies
  • Quizzes and Open Forum

Chiral Fingerprinting:

  • Understanding chiral isomers
  • Method principle and steps
  • Applications in source investigations and allocation
  • Specific examples for PCBs investigations and forensic toxicology studies
  • Quizzes and Open Forum



Online Course Background:

"Fingerprinting" unlocks the mystery of contaminant source identification, age-dating and allocation.

Laboratory and field advances are redefining environmental forensics for a spectrum of contaminants (e.g., crude oil & distillates, chlorinated solvents, metals, PCBs, PAHs, perchlorate, nutrients).

These advances are capable of revealing multiple releases in common chemistry conditions. Emerging technologies are being used today for more applications, with more certainty and more financial assurances. Technology has progresses since the times we could simply differentiate old contamination from newer releases.

Legal arguments are part of environmental forensics as much as technology. Defending or arguing against a fingerprinting process contains hidden challenges that are known to attorneys and expert witnesses. Don't be ill-prepared for a fingerprinting project that will be scrutinized by others.
