Purple Pipes: Promises and Precautions for Water Reuse
The reclaimed water workshop, held on April 16, 2008, in collaboration with UA Cooperative Extension was a success. About 80 people, from state agencies, universities, municipalities and utilities attended the workshop that was held at the UA Maricopa Agricultural Center in Maricopa, AZ. There is a strong interest in the benefits and hazards of using this new water source. Public health issues, turf management, utilities' experiences, regulation, current research, etc., were all part of the informative sessions. After the following presentations were given, participants were given a tour of the Global Water Center an US Arid-Land Agricultural Research Center facilities.
Reclaimed Water vs. Gray Water vs. Wastewater - Channah Rock, Water Quality Specialist, University of Arizona Department of Soil, Water, & Environmental Science
Bacteria in Reclaimed Water Used for Municipal Irrigation: Cause for Concern? - Jean McClain, Microbial Ecologist, US Department of Agriculture
Irrigation of Turfgrass With Effluent: Agronomic Implications - Paul Brown, Specialist, University of Arizona Department of Soil, Water, & Environmental Science
Is Water Recycling a Risk to You? - Hodon Ryu, Assistant Professor, Civil & Environmental Engineering, Arizona State University
Human Contaminate Control and Water Recycling - Chuck Gerba, Professor, University of Arizona Department of Soil, Water, & Environmental Science, University of Arizona
Panel Discussion:

Municipal Reclaimed Water - What does the Public Think? - Bradley Hill, Water Resource Manager, City of Flagstaff
Trace Chemical Contaminants in Water and Wastewater - Semiarid Perspectives
The University of Arizona Water Sustainability Program in collaboration with the Arizona Water Institute offered a one day workshop in Phoenix, on March 2, 2007, to inform participants about "Trace Chemical Contaminants in Water and Wastewater - Semiarid Perspectives." The workshop was geared to the needs of water managers and decision makers to provide an update on emerging water contaminants of concern in the state. Leading experts from The University of Arizona, Arizona State University, Northern Arizona University, state and federal agencies and the private sector gave presentations on the most recent research findings of occurrence, environmental impacts, health effects, fate and treatment for an array of emerging chemical contaminants in our waterways including estrogens, PBDEs, new disinfection byproducts, nanoparticles and heavy metals. Perspectives from ADEQ and the Arizona Water Institute wrapped up the day. The following presentations were given:
Contaminants in U.S. Streams - Ed Furlong, National Water Quality Lab - USGS
Pharmaceuticals and other Organic Wastewater Compounds in Arizona's Effluent and Implications for Water Reuse - Gail Cordy, Geohydrologist, USGS (retired)
New Disinfection By-products - Zaid Chowdhury, Senior Associate, Malcolm Pirnie, Inc.
Detection and Fate of Nanomaterials During Water and Wastewater Treatment - Paul Westerhoff, Associate Professor, Civil & Environmental Engineering, Arizona State University
Perfluorocarbons in the Environment: Fate, Persistence and Remediation Options - Eduardo Sáez, Professor, Chemical & Environmental Engineering, University of Arizona
Estrogens and PBDEs in Wastewater and Sludge - Dave Quanrud, Research Scientist, Office of Arid Lands Studies, University of Arizona
Disruption of Behavior and Development by Environmental Contaminants: from Single Compounds to Complex Mixes - Cathy Propper, Professor, Biological Sciences, Northern Arizona University
The Ecological Effects of Endocrine Disruption; Quantification in a Threatened and Endangered Fish Species - David Walker, Research Scientist, Environmental Research Laboratory, University of Arizona

Innovations in Arsenic Management for Water Providers
The University of Arizona Water Sustainability Program in collaboration with the Arizona Water Institute and Superfund Basic Research Program offered a one day arsenic workshop, on February 17, 2006, at UA CEAC, to inform participants about response options for the new arsenic MCL. Leading Arizona experts on arsenic occurrence, regulatory activities, health effects, treatments for arsenic removal, and management of arsenic-bearing residuals presented talks of interest to everyone concerned about arsenic regulation as it affects Arizona water supplies. The following presentations were given:
Regulatory Background and Extent of Problem - John Calkins, Arizona Dept of Environmental Quality
Geology and Occurrence of Arsenic in Groundwater - Kristine Uhlman, Senior Program Coordinator, UA School of Natural Resources
Health Effects due to Arsenic Exposure - Vasken Aposhian, UA Professor, Molecular & Cellular Biology
