 Latest Developments

  • Dr. Odencrantz recognized for making major contributions to advancing the art, science and practice of engineering by the Civil&Environmental Engineering-CEE Department at the University of Maine at Orono-UMO. Dr. Odencrantz was nominated by the UMO CEE Department and inducted into the Francis Crowe Society as a Distinguished Engineer.
  • EPA Adds Orange County North Basin Site to Superfund National Priorities List. This groundwater contamination site, which includes parts of Fullerton, Anaheim, and Placentia, is now on the Superfund National Priorities List (NPL), making it eligible for federal funding and support for cleanup.

  • Animation of landfill gas/vapor leaks at a Class I Landfill Site in Southern California. Real-time measurement of methane concentrations in conjunction with Google Maps with GPS coordinate transmission from a moving vehicle. Dr. Joseph E. Odencrantz, California Professional and Licensed Civil Engineer C 61137, was a consultant on this project and provided input on the development of the production. A major film and television production company created the video for this Pro Bono effort.  LINK
  •  Vapor Intrusion Investigations and Decision-Making: A Critical Review by Jie Ma,* Thomas McHugh, Lila Beckley, Matthew Lahvis, George DeVaull, and Lin Jiang, Environmental Science &Technology. This comprehensive analysis of vapor intrusion covers the advances in our understanding of vapor intrusion over the last 20 years. It reviews over 250 publications related to vapor intrusion site investigation and decision making. The paper covers conceptual site models, pathway screening, vapor intrusion investigation tools, and challenges in site decision-making. The paper identifies key data gaps for future research. This comprehensive review will be a valuable resource for vapor intrusion researchers, practitioners, and regulators. The paper is an open access article. Dr. Odencrantz’s contributions on innovative technologies are cited three times in the journal article (References 138, 140 and 231). LINK
  • February 6, 2020 Response Levels Lowered for Water Systems Statewide as PFAS Investigation Continues New Stricter Standard Established for PFOA and PFOS. The State of California Water Resources Control Board will set new response levels (RLs) of 10 parts per trillion (ppt) for PFOA and 40 ppt for PFOS. PFOA and PFOS are part of a broader group of per- and polyfluoroalkyl substances (PFAS) that includes nearly 5,000 chemicals LINK
