Sharon B. Megdal, Ph.D. is Director of The University of Arizona Water Resources Research Center (WRRC), a Cooperative Extension center and a research unit in the College of Agriculture and Life Sciences. Her work focuses on water policy and management, on which she writes and frequently speaks. Other primary titles are Professor and Specialist in the Department of Environmental Science, C.W. & Modene Neely Endowed Professor, and Distinguished Outreach Professor.
The geographic scope of Dr. Megdal’s work ranges from local to international. Projects include comparative evaluation of water management, policy, and governance in water-scarce regions, groundwater recharge, and transboundary aquifer assessment. She is the lead editor of the book, Shared Borders, Shared Waters: Israeli-Palestinian and Colorado River Basin Water Challenges and she has guest edited several journal issues. Her policy columns and Reflections essays can be found at https://wrrc.arizona.edu/director. Dr. Megdal teaches the multi-disciplinary graduate course “Water Policy in Arizona and Semi-arid Regions”. In 2020, she was awarded the Warren A. Hall Medal for lifetime achievement in water resources research and education by the Universities Council on Water Resources.
Sharon Megdal serves as Board President, International Arid Lands Consortium and Board Member, American Water Resources Association. She is also an ex officio member of the Leadership Team for the Colorado River Basin Water & Tribes Initiative. From 2009 through 2020, she represented the residents of Pima County on the elected Board of Directors for the Central Arizona Water Conservation District, also known as the Central Arizona Project (CAP), serving as Board Secretary from 2016 through 2020. Dr. Megdal has served on numerous Arizona boards and commissions, including the Arizona Corporation Commission, the State Transportation Board, and the Arizona Medical Board. She holds a Ph.D. degree in Economics from Princeton University. Dr. Megdal’s full CV can be found at wrrc.arizona.edu/director.

ABSTRACT: Assessing groundwater resources in the arid and semiarid borderlands of the United States and Mexico represents a challenge for land and water managers, particularly in the Transboundary Santa Cruz Aquifer (TSCA). Population growth, residential construction, and industrial activities have increased groundwater demand in the TSCA, in addition to wastewater treatment and sanitation demands. These activities, coupled with climate variability, influence the hydrology of the TSCA and emphasize the need for groundwater assessment tools for decision-making purposes.
Groundwater is an important water supply for meeting municipal, industrial, and agricultural water demands and for supporting riparian and other ecological systems in the United States (U.S.). Effective groundwater governance is therefore crucial to the wise use of this largely non-renewable resource (recharge rates are slower than extraction rates). While minimum, federally-established drinking-water quality and water-discharge regulations do exist, the framework of the laws and regulations governing groundwater use in this country is highly decentralized.
This project aims to evaluate the potential of reused grey water in concrete and mortar in order to preserve fresh water for drinking purposes. Using both Treated Grey Water and Raw Grey Water (TGW and RGW, respectively) led to a significant increase in the initial setting time and a decrease in the concrete slump value.
The interconnectivities of groundwater to food, energy, and the climate are addressed to various degrees at the state level. Groundwater governance in the United States is decentralized, resulting in considerable variations in state practices. This article, published in Jurimetrics and written by Sharon B. Megdal and Jacob Petersen-Perlman, reports on two state-level surveys and three regional case studies conducted to better understand groundwater governance strategies and practices. The article also relates the results of these research efforts to food, energy, and climate.
