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 - Binational Studies of the Transboundary San Pedro and Santa Cruz Aquifers: Results and Future Directions

Elia Tapia, Graduate Research Assistant, University of Arizona WRRC
The Santa Cruz and San Pedro aquifers are important sources of water for the Arizona-Sonora border region. Even though groundwater from these aquifers is an essential resource for social, economic, and environmental needs in both countries, assessments of these aquifers had not been conducted by a binational team until more recently. We invite you to attend this brown bag presentation, where we will share information from the binational studies of the Transboundary San Pedro and Santa Cruz aquifers. The studies were conducted in partnership with the USGS, the University of Sonora, and others. The presentation will involve members of the USGS-UA team involved with studying the Arizona-Sonora aquifers. We will also discuss future directions for studying these aquifers.
The Binational Study of the Transboundary San Pedro Aquifer is the first-ever binational aquifer study released simultaneously in English and Spanish by the International Boundary and Water Commission. For electronic copies of the report, please visit http://www.ibwc.gov/EMD/reports_studies.html#WQReports for English, or visit www.cila.gob.mx/as/ebsatrsp2016.pdf for Spanish. Click here for a summary of the study. The Binational Study of the Transboundary Santa Cruz Aquifer is currently undergoing review and should be published later this year. Please join us for this informational session.
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.
