The objective of this Statement of Need (SON) is to solicit fundamental and applied research that leads to better pathway assessment for vapor intrusion from chlorinated solvent-contaminated groundwater. Specific objectives include:

  • Gain a better understanding of natural spatial and temporal variations in vapor intrusion measurements and how to account for such variability in pathway assessment.
  • Improve our ability to obtain accurate and cost-effective characterization of key site parameters that impact the vapor intrusion pathway.
  • Improve our ability to predict vapor behavior under various physical, climactic, and/or geochemical conditions.
  • Improve our understanding of vapor attenuation mechanisms

The projects listed below were selected to address the objectives of this SON. Additional information on individual projects can be found by clicking the project title.


    • Lead Investigator: Dr. Paul Johnson, Colorado School of Mines, Department of Civil and Environmental Engineering

    • Lead investigator: Dr. Tissa Illangasekare, Colorado School of Mines, Department of Civil and Environmental Engineering

Research proposals will lead to the development of a greater understanding of the vapor intrusion pathway from chlorinated solvent-contaminated groundwater plumes will improve our ability to provide more accurate prediction, monitoring, and management methodologies. Research conducted through this SON will ultimately lead to development of a more cost-effective protection of human health.
