Beyond the Response: A look at the science and policy behind dispersants

December 15, 2015 | Webinar

This special webinar was held as part of the US Coast Guard Sector New Orleans Area Committee meeting agenda. Seminar speakers shared information on dispersants, examining them from scientific, legal, and policy angles. Scientific topics covered include toxicity testing of chemical dispersants, development of new dispersants, and efficacy of dispersant formulations. Legal and policy issues were considered as well – including the EPA proposed rule (Subpart J) to the National Oil and Hazardous Substances Pollution Contingency Plan (NCP).

Sea Grant-GoMRI partnership to share oil spill science

The Science and Technology of Dispersants
Vijay John, Ph.D. is the Leo S. Weil Professor of Engineering at Tulane University and a Professor in the Department of Chemical and Biomolecular Engineering. He focused on dispersants from a chemistry and physics perspective – including explanations on properties of dispersants, how they react under different conditions, and how existing formulas may be manipulated to create new dispersants.
