The Compound Specific Isotope Analysis (CSIA)* laboratory provides isotopic characterization of individual compounds. We currently offer analysis of stable carbon, chlorine and/or hydrogen isotopes for many different contaminants of concern. The isotopic data can be used to:

  • Prove biodegradation is occurring
  • Identify mechanisms of degradation
  • Determine the rate and extent of degradation
  • Establish multiple sources of contamination

Applications for CSIA include:

Chlorinated Solvents
Petroleum Hydrocarbons
Fuel Oxygenates
Inorganic Compounds: Nitrate, Sulfate
