Get Answers About Isotopic Fingerprinting:

Stable isotopes are a common tool for differentiating differences in organic contaminants and are routinely used in source identification. Isotopic fractionation and enrichment factors are being used more often for common chemistry conditions. Degradation-related isotope effects are strong for the atoms included in the chemical bond being broken while the remaining atoms experience weak secondary isotope effects.

Session one is dedicated to isotopes for environmental forensics. The two-part session unveils the mystery of conventional isotopic wisdom and takes applications to the most sensitive analysis.


Part 1 will cover:

  • Understanding stable isotopes
  • Measurement and reporting of isotopic data
  • Source identification principle
  • Weathering (main interfering factor) and stable isotopic fractionation /enrichment factors
  • Types of stable isotopic fingerprinting methods:
    • Bulk isotopic analysis
    • Compound specific isotopic analysis (CSIA)
    • Position specific isotopic analysis (PSIA)
  • Stable isotopic fingerprinting in support of site investigation and remediation:
    • Isotopic data for MNA evaluation
    • Isotopic data for building reliable site conceptual models
  • Specific applications for crude oil & petroleum products, chlorinated solvents, metals, PCBs, perchlorate, nitrates

Part 2 will cover:

  • Understanding radioisotopes
  • Measurement and reporting of isotopic data
  • Age-dating principle using the decay law and specific "half-lives"
  • Methods based on radioisotopes:
    • Sediment core age-dating
    • Atmospheric tracers
  • Specific applications for chlorinated solvents & nutrients age-dating



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.
