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.
The Santa Cruz River Heritage Project – Reviving an Urban River
Tim Thomure, Director, Tucson Water
In 2016, the City of Tucson initiated a discussion about using reclaimed water to restore perennial flow to a portion of the Santa Cruz River near downtown Tucson. This action could support riparian habitat in the urban core, improve long-term water management in the region, and stimulate economic activity. The concept was well received by a multitude of stakeholders and Tucson Water began the tasks of bringing this vision to reality. In May 2019, perennial flow will return to the Santa Cruz River near Tucson’ Birthplace, and a new era of water management will begin. This presentation will provide an update on the project, discuss the challenges that lie ahead, and advise attendees of what they can do to support the Santa Cruz River Heritage Project.

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.
