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.

Sharon B. Megdal 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. She also holds the titles: Professor and Specialist, 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. Her policy columns and Reflections 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”.
Sharon Megdal serves as Board President, International Arid Lands Consortium and Board Member, American Water Resources Association and represents 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). The CAP delivers Colorado River water to Central Arizona. 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.

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.
Groundwater, the "invisible water," is difficult to assess, manage and govern for many reasons, mostly due to the unknown quantities of the resource. Political boundaries dividing groundwater aquifers make assessment even more challenging. This article focuses on lessons learned from the hydrologic assessment of the Transboundary San Pedro and Santa Cruz aqufiers. The authors conducted the work in two phases: (1) laying the groundwork and (2) implementation.
Groundwater governance and management practices vary considerably across the United States. To better understand groundwater governance strategies and practices connected to water quality in the United States, a team from the University of Arizona Water Resources Research Center designed and launched a nationwide survey in 2016. The goal of the project was to identify on-the-ground practices of groundwater governance that may help to improve and enhance management of the nation’s water supplies, particularly within the realm of groundwater quality.
Groundwater is increasingly important for meeting water demand across the United States (U.S.). Forward thinking governance and effective management are necessary for its sustainable use. In the U.S., state governments are primarily responsible for groundwater governance (i.e., making laws, policies, and regulations) and management (i.e., implementation of laws, policies, and regulations). This decentralized system results in diverse strategies and practices. We surveyed a water quality professional from each state to better understand commonalities and differences across states.
