Environmental Forensics

Environmental Forensics

  • What is “Environmental Forensics”?

  • “Environmental Forensics” can be defined as a scientific methodology developed for identifying petroleum-related and other potentially hazardous environmental contaminants and for determining their sources and time of release. It combines experimental analytical procedures with scientific principles derived from the disciplines of organic geochemistry and hydrogeology. Environmental Forensics provides a valuable tool for obtaining scientifically proven, court admissible evidence in environmental legal disputes.
  • Much of the information required in this approach will not be obtained from the data obtained using the conventional EPA methods

Basic Environmental Forensic Questions

  • What is the product?
  • Is there more than one source and, if so, which one caused the problem?
  • How long has it been there?
  • Is it degrading?

RITS Fall 2008: Utilization of Stable Isotopes...

*

With any forensic environmental study the basic questions that must be asked are summarized here. First what is it? A second question how many sources and if more than one which one (s) is causing the problem. Then how long has it been there-the reason for this is basically did you own the site when the spill occurred. If it can be shown the age of the spill is such that it occurred before you owned the site that is very advantageous. Finally is the product degrading? This becomes important for cleanup processes. Can you demonstrate natural attenuation is occurring-if so then that is very advantageous for clean up strategies.

GC Fingerprints of different products

  • Although GC permits product identification, many gasoline samples, for example, will be chromatographically similar, even if from different sources.
  • Refined products generally do not contain biomarkers making GCMS of little consequence.
  • If refined products are from different sources, stable isotopes may provide a potential solution.

Utilization of Stable Isotopes

  • What is the product? NO
  • Is there more than one source and, if so, which one caused the problem? YES
  • How long has it been there? NO
  • Is it degrading? YES

RITS Fall 2008: Utilization of Stable Isotopes...

*

This is basically indicating which questions listed in the previous slide can be addressed through the use of stable isotopes.

Why do compounds derived from different feedstocks have different isotope values?

Utilization of Stable Isotopes

*

Carbon Isotopes

  • Carbon in fossil fuels is initially derived from atmospheric CO2. During photosynthesis, fractionation of the two isotopes occurs with preferential assimilation of the lighter isotopes.

*

Carbon Isotopes

  • Extent of fractionation during photosynthesis depends on factors such as: plant type; marine v. terrigenous; C3 v. C4 plant types; temperature; sunlight intensity; water depth.
  • (C3Temperate plants; trees; not grasses; 95% plant species -22 to -30; C4 plants grasses; sugar cane; corn; higher temps and sunlight-10 to -14 per mil)

Stable Isotope Determinations

ISOTOPIC VALUES CAN BE MEASURED IN TWO WAYS:

  • BULK ISOTOPES

  • ISOTOPIC COMPOSITIONS OF INDIVIDUAL COMPOUNDS

Correlation Using Bulk Isotope Ratios

Gasoline

RITS Fall 2008: Utilization of Stable Isotopes...

*

Brand A gasoline clearly different than brand B gasoline. Gasoline in groundwater degraded relative to Brand A and cannot be from Brand B. This is an example where the bulk C and H isotopes were determined on the gasoline samples and used to discriminate samples of different origins and to relate one source to the samples in the monitoring wells.

Gasolines

  • Gasolines from different sources often have very similar chromatograms, making it difficult to distinguish such samples
  • Gasolines are also devoid of biomarkers, further limiting correlation possibilities
  • One solution here is to use GCIRMS for both the hydrocarbons and additives

RITS Fall 2008: Utilization of Stable Isotopes...

*

This is another example of the advantage of using isotope compositions of individual compounds in gasolines. Again gasolines are chromatographically very similar even when coming from different sources. Hence GC and GCMS are of relatively little use in discriminating samples from different sources. However if the gasolines are derived from different crude oils it may be possible that the isotopic fingerprints can be used to differentiate the products.

RITS Fall 2008: Utilization of Stable Isotopes...

In a previous slide the bulk isotope values for a brand A and brand B gasoline were given. However these bulk values are the weighted averages of the isotopic compositions of all the individual compounds in the gasolines. Here is a portion of a gasoline chromatogram that has been analysed by GCIRMS and the isotopic compositions of several individual compounds are shown. The variations in these individual compounds highlights the fact that the isotopic fingerprint potentially provides another tool that can be used to differentiate products from different sources providing far more specificity than the bulk values alone.

The cross section close to the source shows that now instead of one homogeneous source there are three isotopically distinct sources across the transect. These three may represent multiple sources or multiple releases from the same source. These variations did not result from biodegradation since no degradation products were observed.

PCBs

  • Study by Yanik et al., OG, 239-253, 34, 2003 showed that different Aroclors may be isotopically different and thus useful for source discrimination although there is some slight enrichment from degradation.

PAHs and Stable Isotopes

  • Current interest is centered around whether carbon isotopes can be used to discriminate PAHs derived from former manufactured gas plant (MGP) wastes versus those from general urban background aromatics
  • Urban backgrounds have a fairly narrow range and small differences may be related to source differences

Summary

  • Environmental Forensics combines a variety of analytical tools to typically provide information on origin and state of contaminants in the environment.
  • One of these tools involves utilization of stable isotopes.
  • In some situations stable isotope data compliments other analytical data. In other cases may be only tool available.
