Achieving Successful Groundwater Recharge and Recovery through Wells
Course Description
The aim of this workshop is to provide attendees with an appreciation and practical understanding of the technical, scientific, engineering design, and other issues that need to be addressed when developing managed aquifer recharge (MAR) systems that utilise wells, whether aquifer recharge (AR) wells, aquifer storage recovery (ASR) wells or aquifer storage transfer recovery (ASTR) wells.
Successful and sustainable recharge via wells requires a collaborative effort by scientists and engineers from across multiple disciplines. Failure of some MAR systems can be attributed directly to the poor design of the wells; inadequate characterization of the source and receiving water, poor engineering design or miscommunication concerning the primary objectives of the MAR system. ASR wells are quite different from standard water supply wells or injection wells.
This workshop will guide participants through the pre-requisites for, and technical feasibility of ASR systems for a variety of water sources, aquifer types, and end uses. The primary focus of the workshop will be on the key technical issues associated with planning, feasibility assessment, design, construction, operation and performance evaluation of recharge and recovery systems via wells. Economic and regulatory issues that impact well performance will also be addressed. Case studies will be used to illustrate the key considerations that need to be employed to deliver successful, integrated and sustainable ASR operations.
The workshop is aimed at MAR practitioners across all experience levels (Basic, Intermediate or Advanced). Some prior knowledge of MAR techniques and terminology is useful but not essential.
Course Instructors
David Pyne (ASR Systems, USA) has over 40 years of experience with well recharge throughout the United States and in many other countries. He coined the term “aquifer storage recovery” and has pioneered the development of that technology. He has a Bachelor’s degree in Civil Engineering from Duke University and a Master’s degree in Environmental Sciences from the University of Florida, specializing in Water Resources Engineering. He has a Professional Engineer license in several states. He has taught numerous ASR workshops since 1994.
Russell Martin (Wallbridge Gilbert Aztec, Australia) has over 35 years’ experience in Hydrogeology across the Public and Private sector. He holds a Bachelor of Science degree from the University of Canterbury and a Master’s degree in Hydrogeology from the Flinders University of South Australia. Russell has worked on more than 60 large-scale multi-faceted MAR/ASR projects across Australia and internationally. Currently he leads the International Association of Hydrogeologists (IAH) Working Group on Clogging during MAR and has delivered numerous technical workshops and training on the topic of MAR.

Meeting Water Management Objectives with Managed Aquifer Recharge: The Role of MAR Governance and Policy
Workshop Description
This first-ever ISMAR workshop on governance and policy aspects of MAR is designed to inform participants on how sound MAR governance and regulatory frameworks can facilitate meeting jurisdictional water management goals. The stresses on both surface water and groundwater systems are leading many to consider MAR implementation. Understanding the elements of successful frameworks will enable policy makers and water managers to shape MAR frameworks for their jurisdictions.
The workshop has three parts. It will open with a presentation on the “Principles on Water Governance” developed by the Water Governance Initiative of the Organisation for Co-operation and Development (OECD).* The principles, which are available in 18 languages here, provide the elements of a strong governance framework for water management. The second portion will focus in on examples of good governance frameworks for MAR, including Israel and Arizona in the United States. The final part will offer presentations about how, based on a sound governance-regulatory framework, MAR has been implemented to further water management and policy goals. With ample opportunity for discussion and questions built into the program, the workshop will provide a great foundation for the conference plenary sessions.
Intended Audience
The workshop is designed for anyone, regardless of background, interested in learning about MAR governance and regulatory frameworks and innovative deployment of MAR projects to meet water policy goals.
Workshop Moderator
Sharon B. Megdal, Ph.D. is Director of the University of Arizona Water Resources Research Center (WRRC) and Professor in the Department of Environmental Science. Her professional experience includes serving as a state utility regulatory, heading a regional water augmentation district, and consulting on water recharge matters.

She has worked with farmers and government agencies to implement recharge projects. Her extensive writings on water management include articles on Arizona water banking and the guest edited (with Peter Dillon) volume, Policy and economics of managed aquifer recharge and water banking. Sharon Megdal has been a member of OECD’s Water Governance Initiative since its 2013 inception. For 12 years Sharon Megdal served on the board of the Central Arizona Project, where she chaired the committee overseeing CAP’s recharge program for five of those years. Sharon holds a Ph.D. in economics from Princeton University.

State of the Art Techniques in Identifying and Characterizing Optimum Surface Spreading Groundwater Recharge Projects
Workshop Description
Successful site selection, design and operations of surface spreading groundwater recharge operations are highly dependent on subsurface geologic conditions, source water quality, land availability and nearby land use. This course is designed to present, discuss and evaluate the best tools for site evaluation and the application of these tools for feasibility studies and recharge system design, to include a review of best management practices for operations. A spectrum of case studies will be presented to illustrate the application of these tools and interpretation of data to include:
- Defining recharge site goals and criteria for selecting an optimum recharge site
- Phased approaches to site characterization and site selection
- Near-surface field methods for hydraulic characterization
- Deep sub-surface field methods for hydraulic characterization and monitoring
- Integration of characterization, monitoring and modeling
- Considerations and methods for maintaining optimum operations
Intended Audience
The course is designed for consulting and government scientists, engineers and managers who are or will be involved in groundwater recharge studies and operations. A background in the physical sciences or engineering is desirable.

Application of Geophysics for Managed Aquifer Recharge
Brought to you by:
Workshop Description
To assess the viability of a site for MAR, detailed three-dimensional (3D) information about the subsurface materials and their hydraulic properties is required. Among a wide variety of applications, surface geophysical methods have been used in MAR projects for improved understanding of the subsurface lithology. Different geophysical methods are sensitive to different physical parameters of the subsurface materials and have their own limitations with respect to the area of coverage, penetration depth, and spatial resolution. To be used effectively, the manager of a MAR project needs a basic understanding of the geophysical methods available and how they can be used to site and improve the efficiency of MAR systems, reduce risk, and reduce costs.
Various methods have been used for various objectives in MAR studies. These methods are described in the workshop and include surface nuclear magnetic resonance (NMR), electrical resistivity, frequency domain electromagnetics (FDEM), time domain electromagnetics (TEM), borehole geophysics and seismic reflection. The objective of this workshop is to provide attendees information on a broad array geophysical imaging methods and practical application through examples and lessons learned. The intent is to provide the project manager with the working knowledge needed to specify and evaluate geophysical surveys that provide the coverage and resolution that are optimal for the assessment of MAR sites for projects targeted at recharging shallow to deeper parts of the groundwater system. The workshop will provide ample opportunity for group discussions, and input on specific projects and site settings.
