The use of per- and poly-fluoroalkyl substances (PFAS) in numerous industrial, commercial, and military applications has resulted in their widespread distribution in the environment. Research reports have demonstrated that PFAS are present in the atmosphere, surface water, sediment, soil, groundwater, treated wastewater, biosolids, landfill leachate, and drinking water. This presentation will briefly discuss the nature, sources, and properties of PFAS, their transport, and fate in the environment, with example case studies.
Brown Bag Seminar - Recent Developments in Atmospheric River Science, Predictions and Applications
Martin Ralph, Ph.D., Director, Center for Western Weather and Water Extremes and Researcher at UC San Diego's Scripps Institution of Oceanography
Key developments have occurred recently on atmospheric rivers (AR). These include advances in observations, physical process understanding, predictions, applications and policies. This presentation will highlight a few of these developments.
- What are atmospheric rivers and why are they important to the Western U.S.?
- Examples of AR with significant impacts in the Western U.S.
- There is skill in AR landfall prediction that could be useful in reservoir operations.
- Atmospheric River Reconnaissance (“AR Recon”): a new airborne targeting approach is under development (including use of aircraft normally dedicated to observation of hurricane activity).
- A critical mass of research and experimental forecast capability, with an emphasis on AR science, predictions and applications, exists at the Center for Western Weather and Water Extremes.
Dr. F. Martin Ralph, a Researcher at UC San Diego’s Scripps Institution of Oceanography, and is the founding Director of the Center for Western Weather and Water Extremes (cw3e.ucsd.edu), is a scientist, manager, and program developer focusing on programs that bridge science and its applications to practical problems, especially related to extreme precipitation events from flood to drought.. He has published over 100 scientific articles, received several awards, and is a Fellow of the American Meteorological Society. His technical background is in atmospheric science, with degrees from UCLA (PhD) and UA (BS)
The Occurrence and Fate of PFAS (Per-/Poly-Fluoroalkyl Substances) in the Environment
Desert Waters International Symposium
In many regions of the world, protecting water for natural areas isan urgent matter. There are many ideas and potential lessons to be learned from our international neighbors to help Arizona reframe the link between healthy watersheds and healthy, thriving businesses and communities.
