In a call for bold innovation, Zenia Tata (Water Abundance XPRIZE) states: “Water is the universal link between human survival, our climate system and sustainable global development”.

The UN Secretary-General's message on World Water Day, on March 22, 2019, stated that 2.1 billion people live without safe water, and that growing demands, coupled with poor management, have increased water stress in many parts of the world. Climate change is adding dramatically to the pressure, and by 2030, an estimated 700 million people worldwide could be displaced by intense water scarcity. The global water crisis is urgent and requires innovation to identify, prioritize, and accelerate global solutions. The focus must include groundwater because it makes up 99% of the Earth's liquid freshwater. The Groundwater Project (GW-Project), a non-profit organization, registered in Canada in 2019, is committed to contribute to advancement in education and brings a new approach to the creation and dissemination of knowledge for understanding and problem solving, relying on experts around the globe to volunteer as authors and reviewers. Motivated by the 1979 textbook “Groundwater” by Dr. Allan Freeze and Dr. John Cherry, hundreds of participants (and growing) from many countries across the Globe are working with a common vision to provide hundreds of digital books and supporting materials, free-of-charge, downloadable at the GW-Project Platform at https://gw-project.org.

The GW-Project is administered at the 1 University of Guelph, ON, Canada.

Mission Promoting Groundwater Learning

Vision Providing knowledge tools for developing groundwater sustainably for humanity and ecosystems.

The GW-Project’s mission is innovative in that it encompasses an entire realm of environmental science (all things groundwater) documented by volunteer experts from around the globe in online books aimed at education for readership at all levels and all global circumstances to serve humanity and our Planet’s ecology. This has not been done before for any realm of environmental knowledge or any other science realm as far as we know and so we should view it as an experiment. But we are now three years into this project, enough to see that the experiment is going well based on the confirmed publication scheduled for this year and 2021 and numbers of committed scientist and practitioners (including retirees) to write and review books. This report is a comprehensive overview of GW-Project vision, groundwater project framework, philosophy, contribution to education, management structure, contributors (authors and reviewers), and books scheduled for publishing in 2021 although it is expected more will be added.

1. Synopsis

The GW-Project is a large international collaborative and continuing effort focused on producing series of high-quality electronic books and supporting materials that will be made available for free at the GW-Project Platform at https://gw-project.org.The GW-Project is the publishing house for all the books. The books are written and edited by expert scientists and practitioners volunteering their time to realize a shared vision: knowledge should be free, and free knowledge should be the best knowledge synthesized in a unifying framework. The GW-Project endeavors widespread groundwater education covering all aspects of groundwater relevant for our world community.

The philosophy behind the GW-Project is to democratize groundwater knowledge meaning that there should be full accessibility to good quality knowledge and the ability to share this knowledge, thereby overcoming current impediments related to groundwater publications. Groundwater suffers from being hidden and misunderstood, and the GW-Project aims to raise groundwater consciousness and educate on what is needed for essential monitoring and sustainable groundwater management (monitoring, corrective actions, and protection).

The GW-Project books will cover nearly all aspects of the hydrologic cycle. Groundwater is the essential sustaining reservoir underpinning all Earth’s freshwater: rivers, lakes, and wetlands. Yet, groundwater is assaulted from all directions mostly because of unintended consequences. The freshwater cycle is losing its resilience because it is dependent on stressed groundwater. Aquifers

The GW-Project is administered at the 2 University of Guelph, ON, Canada. are being pumped unsustainably, chemical pollution is common, and the types of groundwater contaminants are increasing. Important knowledge needs to be captured before it is lost as groundwater practitioners age. Many who have conducted foundational studies since the 1970s are volunteering to transfer their wisdom through the GW-Project, which aims to capture their reflections and synthesis. Groundwater is not treated as a specific educational unit in academia. Although interdisciplinary treatment of groundwater in academia provides rich diversity in approaches and perspectives, the concept that groundwater is the sustaining force of surface water and its ecological systems is greatly underappreciated. The GW-Project, by design, will present groundwater as the integrative theme for understanding subsurface and surface freshwaters in both their natural and disrupted states. Further readings on the GW-Project philosophy are presented in Appendix A. The GW-Project is strategically positioned to make an unparalleled unprecedented contribution to education. The objective of the GW-Project with respect to university education is twofold: to achieve more effective learning and to free up time for instructors to engage the students in experiential learning, which requires hands-on lab experiments, field activities, and active modeling exercises. Hence, the GW-Project is planning to prepare learning modules and videos and is seeking advice and examples of effective field and laboratory exercises aimed at engaging students in hands-on activities. Key to the mission of the GW-Project is to foster rapid knowledge dissemination and methods to universities everywhere including those in developing countries so that those with inadequate teaching resources for comprehensive groundwater education can direct their students to synthesized knowledge at a high global standard. Emphasis is on overcoming inadequacy in knowledge and technical resources for improved access to safe drinking water in both remote rural areas and the large urban centers where there is water poverty. GW-Project contribution to education is described in Appendix B.

The GW-Project scope has evolved over time, and what started as an initiative for developing books with university education in mind evolved to a scope that includes books for everyone everywhere. To that end, The GW-Project is organized into four categories and 23 Domains which contain Topics and Books covering broad themes in groundwater. Many Books have supporting materials ranging from basic to advanced that enhance knowledge coverage. The categories are:

1. Children’s Books - dedicated to all sorts of groundwater information for children; designated as Domain A Books. 2. Introductory Books - covers a wide range of groundwater topics, written for a broad audience; designated as Domain B Books. 3. Overview Books – comprehensive books which cover groundwater topics in a larger context in a descriptive manner (mostly without equations); designated as Domain C Books. 4. Specialized Books – primarily tailored towards groundwater education at the university level and continuing education for groundwater professionals; designated as Domains D through W Books.

The GW-Project is administered at the 3 University of Guelph, ON, Canada.

The 23 domains are described in Appendix C.

The 23 Domains

The GW-Project is administered at the 4 University of Guelph, ON, Canada.

The GW-Project is led by Dr. John Cherry, recipient of the 2020 Stockholm Water Prize, and managed by a 11-member Steering Committee and larger and globally diverse Advisory Committee. Appendix D introduces the team and provides further information on the GW- Project management. Nearly 400 well-recognized scientists from around the world have agreed to participate as authors and reviewers, and more are engaging. These contributors are associated with over 200 organizations worldwide. The United States Geological Survey (USGS) has been for a hundred years the world’s leading groundwater research organization and the GW-Project is honored with the large number of emeritus and current USGS scientists contributing as authors. Appendix E includes the complete lists of authors, reviewers, and participating organizations. The GW-Project aims for widespread global education about groundwater; materials are produced in English first and soon after translated into several other languages. Work on the GW-Project began in 2017, and the first round of publications is planned for release in August 2020. More than 200 books are actively in preparation by experts around the globe for publication in 2020 and 2021. The GW-Project ultimately expects to publish hundreds of books over the next few years.

The Groundwater Project Framework

The GW-Project is administered at the 5 University of Guelph, ON, Canada.

2. The GW-Project Website

The GW-Project website https://gw-project.org was launched on March 23, 2020. The latest technology is being used to run and maintain this website to ensure optimal functioning of the GW-Project Platform on which all books and related material are published and made available to the world. The GW-Project endeavors to become the global provider of educational materials for students and practitioners through this platform.

The website is fully functional, showcasing information about the GW-Project, published books, upcoming books for publication, and information on how to donate and support the GW-Project. The GW-Project provides books (PDF Format) free-of-charge and can be downloaded from the website. Books are also now available as webbooks.

We like to encourage users to sign up to the GW-Project email list to stay informed about new book releases, events, and ways to participate in the GW-Project. This signing up will also help us build a global groundwater community.

The GW-Project will initially connect to the global groundwater community through supporting partner organizations, and then build on this through its own communications so that the widest global distribution is accomplished instantaneously when new books or materials become available. There are almost 5000 registrations from over 150 countries, which is a testimony that the GW-Project is gaining world recognition across sectors. To date our books have been downloaded over 35,000 times.

Each book is an official publication (electronic only) with an ISBN number; intellectual property will be respected, and content producers will have their names clearly displayed on their material. The website will offer free downloads of the books. Efforts are underway to translate the books in various languages, including French, Spanish, Portuguese, Chinese, Russian, Turkish, and Arabic.

The GW-Project is administered at the 6 University of Guelph, ON, Canada.

3. Ways to Contribute to the GW-Project

The driving force and success behind the GW-Project are the contributions of volunteers, so far mostly from groundwater professionals in the public and private sectors (scientists and consultants), including retirees.

However, anyone can contribute, and there are three main ways:

1) Facilitating the production of published materials, including editing, reviewing, and helping with organization and management. 2) Direct engagement as author or co-author in the preparation of original materials to be published. 3) Assisting with figure creation and graphics for books, marketing purposes and social media. 4) Translations or management of translations.

We are also always seeking to expand options for participation. The GW-Project plans to publish, in addition to the books, other types of publications to serve the needs of the wide variety of groundwater stakeholders and others interested in groundwater and related topics; all submissions are subject to rigorous peer review:

1) Short books similar to conventional book chapters, but with enhanced flexibility provided by publishing only in electronic form. Each is part of a plan for subject coverage within the knowledge Domains. Nearly all of these are solicited contributions.

2) Monographs in the style of conventional monographs or a new style better suited to electronic publishing. The GW-Project seeks materials that represent synthesis of science that can help understanding of groundwater in ways that can serve any segment of society. Monographs are especially sought for explanations and guidance on ‘how to do’, including applications of software, monitoring methods, hydrogeophysical methods, and syntheses of major groundwater studies geared towards educational purposes.

3) Open source software with guidance for use and example applications.

4) Reports on significant advances in groundwater science but not well suited for publication in peer-review journals. The GW-Project is soliciting reports in some immature topic areas to get the thoughts of the most knowledgeable people in the world associated with emerging issues or problems.

5) Course notes that are well annotated, either by extended text and/ or voice recorded text. These notes/ lectures may be based in part or entirely based on GW-Project materials presented in GW-Project books. The intent is to invite instructors to contribute an entire course that they teach at their institution to be distributed by the GW-Project as a stand- alone package.

The GW-Project is administered at the 7 University of Guelph, ON, Canada.

6) Worked problem sets as examples of problem formulation and solutions with emphasis on real-world relevance including transdisciplinary examples. Many of the books will have associated problem sets; however, the GW-Project welcomes stand-alone contributions of this nature as carefully prepared problem assemblages with worked answers. Talent and creativity are needed to produce effective problem sets for learning and the GW-Project seeks to make such creations available for global learning.

7) Many old (decades ago) publications about groundwater topics that have continuing value because of their exceptional rigour or clarity or because they were of great importance in the evolution of groundwater science. Some such publications are in danger of slipping so far from view that younger generations never know of their existence (e.g., lack of recent citations or easy access). The GW-Project seeks to rescue some of these publications, especially those out of print or rare, such as some publications produced by government agencies or in languages other than English.

8) Books and videos for youth: we have already published on our website the decades-old children’s book Wally and Deanna’s Groundwater Adventure and we are seeking more high- quality children’s books that are worthy of a global readership. We have dedicated a separate category to this.

9) Contributions from the accomplished senior generation of groundwater researchers on topics of their choice. This category represents respect for the views of those who have acquired a lifetime of valuable experience solving groundwater problems or managing groundwater projects.

The GW-Project is administered at the 8 University of Guelph, ON, Canada.

4. The GW-Project Progress and Next Steps

Proof of Concept Phase: 2017-2020

The vision for the GW-Project began to form in 2017 and is now well advanced. The ‘proof of concept’ phase ended in 2020 with the accomplishing of the following:

✓ A comprehensive and well-organized listing of subject Domains and the hundreds of books within Topic areas encompassing nearly the entire scope of groundwater to serve the needs of both the developed and developing countries (see Appendix F). ✓ Commitments from a large number of recognized authors to populate sufficient Domains and Topics to establish feasibility of the larger vision and show credibility of the GW-Project (Appendices E.1 & E.3), with a large number of contributors from emeritus and current scientists of the US Geological Survey (Appendix E.4). ✓ Committed participants well distributed across the globe in both developed and developing countries, representing many expertise specialties and a variety of career stages, including government and world organizations’ researchers, academics, and practitioners to demonstrate scope and inclusiveness. ✓ Engagement of a large number of world-recognized groundwater scientists and engineers and practitioners in the senior stage of their careers so that the knowledge and wisdom of this generation is being captured effectively to serve future generations. ✓ A comprehensive educational philosophy and methodology for the GW-Project including the use of cutting-edge digital technologies to advance well beyond the confines of the conventional educational textbook (Appendix B). ✓ A formalized and rigorous peer-review process applied to all materials issued by the GW-Project. List of reviewers is shown in Appendices E.2 & E.3. ✓ The GW-Project website up and running, with ten published books in 2020, demonstrating that the electronic publishing and tracking processes is functioning properly. ✓ A GW-Project registration list with thousands of email addresses distributed globally to show the GW-Project is gaining world recognition across sectors. ✓ Active engagement of well-qualified people from both the academic and the practitioner communities across many disciplines that make up the larger groundwater community and stakeholders to show that the GW-Project has the credibility and strategy to continue to expand participation in the next few years. ✓ Demonstrated in-kind support (engagement) from government organizations such as geological surveys and associations to show the GW-Project is aligned with many other organizations around the globe.

The GW-Project is administered at the 9 University of Guelph, ON, Canada.

✓ Sufficient progress to demonstrate the GW-Project is on track to publish appropriate materials to inform and contribute to learning at the lay-person level as well as the university and practitioners’ level, and thus appropriate for raising groundwater consciousness worldwide. ✓ A framework to prepare translation of the initial GW-Project publications into several other languages. ✓ Positive feedback from user communities to the initial published products to indicate the GW-Project is on a good track with its approach to book design. ✓ Solid progress in both identifying and organizing access to open-source software (free of charge), relevant to all aspects of groundwater. ✓ Books published in several Domains, providing a good example about the type of books the GW-Project publishes; the books also reflect the particular needs for a domain. ✓ Expert advisory teams established for most of the 23 Domains to help design and guide the progress of each.

Overall, the goal of this proof-of-concept phase is to demonstrate the GW-Project has established appropriate approaches, procedures, and strategies to move forward and bring many more materials to publication on the website (gw-project.org) and successfully democratize groundwater knowledge. On March 23, 2020, the GW-Project website invited anyone interested across the globe to participate. This is a standing invitation, and we expect offers will continue to increase into 2021 as more books are published on the website.

Children’s books

The GW-Project distributes translations of Wally and Deanna’s Groundwater Adventure: Leanne Appleby and Peter Russel. The Spanish translation was completed by Luis Camilo Suescún (published on December 15, 2020).

Legacy Books

The GW-Project distributes the Portuguese translation of “Groundwater’ by Alan Freeze and John Cherry. The translation “Água Subterrânea” was completed in 2017.

Next Steps All books in this first set of publications were solicited. During 2021 we will gain experience in accommodating unsolicited offers via the website. To date, the GW-Project has made good progress by steadily soliciting additional expert participants through invitations based on the knowledge about global expertise within the Steering Committee and their expanding contacts. The plan is for this controlled approach relying on solicited invitations to author books to continue during 2021 as we assess and integrate unsolicited offers. An objective is for unsolicited offers to create materials for the GW-Project to increase engagement from all groundwater stakeholders. All materials published by the GW-Project will be living documents and therefore will be improved and updated as opportunities arise. In 2021, we expect to initiate procedures whereby improvements submitted by anyone concerning materials already published by the GW-Project can be accommodated in agreement with authors. In 2021 and beyond, the GW-Project will focus on seven categories of activities:

1) Production of many more books with global expansion of expert participation. 2) Translations of books into several languages. 3) Active collaborations with organizations around the globe engaged in the creation and/or delivery of educational materials based on the GW-Project aimed especially at developing countries. 4) Collaborations with professors engaged in using GW-Project books in their courses aimed at improved online courses. 5) Adapting published GW-Project books into active self-learning modules, including professionally developed video presentations. 6) Production of materials to facilitate public engagement around the importance of studying and protecting groundwater resources. 7) Webinars to introduce GW-Project books so users of the book will have improved perspective on the subject matter including the background about the materials.

The GW-Project is administered at the 11 University of Guelph, ON, Canada.

Self-learning multimedia electronic modules The books will present the synthesized knowledge that students need to strive to understand, but the learning process requires active teaching modules to develop and test understanding. Experience with the preparation and delivery of active teaching modules exists in other organizations, such as the Khan Academy. The GW-Project will seek appropriate collaborations with educational institutes to realize the creation of the self learning modules. In addition, teaching videos will be prepared to show activities in the field and laboratory and bring groundwater processes and methods of data acquisition to life.

Fundraising Activities The GW-Project is volunteer-based but has required funds for administrative support and to bring the GW-Project successfully through the proof of concept phase. This support has come from a few donations and from the G360 Institute for Groundwater Research at the University of Guelph. The GW-Project is a non-profit organization and soon to be a registered Canadian charity in 2021. Major funding is needed in 2021 and beyond to support the next phase of the GW-Project. To that end the GW-Project has started active fundraising activities. Ultimately, the funding goal is for the GW-Project to become sustainable in the longer term as a living organization and can continue expanding its activities and global reach.

The GW-Project is administered at the 12 University of Guelph, ON, Canada.

Appendix A: The GW-Project Philosophy and Justification

“Knowledge should be free, and the best knowledge should be free knowledge.” Anonymous

We are in a global water crisis. Unfortunately, the enigmatic and elusive groundwater portion of Earth’s water is commonly misunderstood, mismanaged, and abused. Nearly all of the Earth’s freshwater is groundwater, which is the buffer of the hydrologic system. Nearly 50% of the world’s population depends on groundwater for domestic use and many more on its irrigation benefits, and this will inevitably increase as the population swells. Groundwater is used locally but is transferred around the world in food and products. There are unprecedented rates of change to the water cycle, and much is out of balance. A key limiting factor to understanding groundwater is that the many advances in groundwater science of the past 50 years are not being put to work in solving today’s problems. The science is not being converted into widely recognized benefits to humanity and the environment. Why? Scientific knowledge is not democratized.

A.1 Democratizing Groundwater Knowledge

Knowledge democratization means full accessibility around the globe. Accessibility is limited by a number of impediments:

1. First is the peer-review journal publication process. Although successful as the gatekeeper for scientific advancement, by design, journals communicate incremental and site/time specific research findings. They do not synthesize the exploding literature into the essence of scientific advances, yet this is needed for education and actionable knowledge to be useful to policy makers and resource managers. 2. Second is the nature by which science value is judged. Journal publication citation statistics are the main criteria for career advancement in universities and strongly influence who receives research funding. The pressure to publish in journals is so great that groundwater literature has grown immense, making synthesis ever more challenging.

A-1

. 3. The third limitation is financial. Research is conducted using primarily public resources through university and government salaries that support the researchers, journal editors, and reviewers; yet, to finance the journal, the journal’s copyright restricts access to only those who can pay. The unintended consequence is that science created with the support of public money for the public good is severely restricted in serving the public good. 4. The fourth limitation is lack of incentives for conversion of the journal outputs into synthesized knowledge for understanding beyond the narrow expertise of its origins. Time spent on writing a book or article of long-term benefit to the broader community does not get administrative support and can restrict career advancement. 5. The fifth limitation is the inadequate field testing of many of the new concepts, models, and technologies to assess advantages to serve societal needs. This results from lack of funding based on lack of understanding of the benefits that groundwater provides to societies and ecosystems. 6. The sixth limitation is the lack of a global database, and the tendency for many governments to keep data from public and researcher’s use due to so-called national security concerns or inconvenience to the bureaucracy. The GW-Project was initiated as a step towards overcoming these impediments to democratization of groundwater knowledge. At its core is a comprehensive and living series of books, free to all, in many languages, to represent expert syntheses from elementary to advanced levels of the state-of-knowledge. This book series will cover all aspects of groundwater science and engineering, with regular updating as the knowledge grows and evolves. It is written and edited by expert scientists and practitioners volunteering their time to realize a shared vision: knowledge should be free, and free knowledge should be the best knowledge synthesized in a unifying framework. The GW-Project is answering humanity’s call to service, to transcend college campuses, national boundaries, language barriers, and socio-economical ladders, enabled by the Internet.

A.2 The Urgency

The GW-Project was born under the spirit of the Encyclopedia of Diderot and d’Alembert. The GW-Project is unique, by focusing on one dominion of knowledge, but is immense as it includes all aspects of how groundwater supports surface waters, ecosystems, and human livelihoods and relates to food and industrial production and societal well-being.

The mission of the GW-Project is urgent for several reasons:

1. First, groundwater suffers from being hidden and misunderstood. The GW-Project aims to raise groundwater into view and educate on what is needed for essential monitoring and sustainable management (monitoring, corrective actions, and protection). Groundwater is the essential sustaining reservoir underpinning all Earth’s freshwater: rivers, lakes, and wetlands. Yet, groundwater is assaulted from all directions mostly because of unintended consequences. The freshwater cycle is losing its resilience because it is dependent on

A-2 stressed groundwater. Aquifers are being pumped unsustainably, chemical pollution is common, and the types of groundwater contaminants are increasing. 2. Second, important knowledge needs to be captured before it is lost as groundwater practitioners age. The foundation for quantitative groundwater science was formed by Hubbert, Meinzer, Thiem, Theis, Terzaghi, and Hantush based on geology, geomechanics, and hydraulics. In the 1980s, environmental regulations triggered an explosion of research cutting across disciplines in surveys, monitoring, experiments, and problem solving, but this knowledge has gone without synthesis. Many who have conducted foundational studies since the 1970s are volunteering to transfer their wisdom through the GW-Project, which aims to capture their reflections and synthesis. 3. Third, groundwater is not treated as a specific educational unit in academia. Although interdisciplinary treatment of groundwater in academia provides rich diversity in approaches and perspectives, the concept that groundwater is the sustaining force of surface water and its ecological systems is greatly underappreciated. The GW-Project, by design, will present groundwater as the integrative theme for understanding subsurface and surface freshwaters in both their natural and disrupted states.

A.3 Scope, Framework, and Strategy

The GW-Project will increase the recognition that groundwater hydrology warrants the importance and complexity that oceanography has achieved in academia. Oceanography is treated as an educational discipline by many institutions, some with dozens of faculty members and dedicated programs. Similarly, the breadth and depth of the groundwater environment needs to be examined and monitored in academic institutions because all terrestrial life depends on freshwater, which is 99% groundwater and rapidly being depleted/degraded.

The GW-Project offers peer-reviewed knowledge synthesized by expert researchers and practitioners for accuracy and comprehension to serve groundwater education in four areas: 1. Students at the university level. 2. The practitioner community of scientists, engineers, and teachers 3. The broader water management and policy community. 4. The general public and high school students.

Currently, the GW-Project is engaged in synthesis of essential knowledge and understanding to frame groundwater education in the fullest sense. As the synthesis proceeds, the GW-Project will provide maps for using the material in various types of courses so that institutions providing groundwater education will be able to choose from the synthesized materials to present comprehensive groundwater education in various circumstances around the globe. This will offer a bridge to the knowledge that is currently fragmented and dispersed across disciplines. In addition to synthesized knowledge and tacit wisdom, the GW-Project is aimed at capturing experiential contributions. Groundwater science is founded on physics, chemistry, and mathematics, but its essence is experiential because the most important observations come from

A-3 the field. The GW-Project applies system concepts to the way that groundwater connects to Earth’s hydrologic cycle, including physical, chemical, and biological processes. The GW-Project recognizes the many influencing factors on local groundwater systems (topography, soil, climate, and human activities). Achieving a general understanding of groundwater requires a holistic synthesis of many different groundwater conditions. Seeing groundwater systems with clarity is encumbered by complexities ranging from geology to transient climate and land use, and consequently field conditions are understood mostly by practitioners who rarely contribute to refereed journals. The overarching goal of the GW-Project is to integrate and synthesize groundwater knowledge across broad perspectives and assimilate it into actionable knowledge in the global context. The GW-Project framework has 23 Knowledge Domains (Appendix C). Each Domain includes books within Topic areas, with multiple books organized under each Topic area (Appendix F). Although the overarching theme is groundwater, the governing factors include fluid mechanics, geology, chemistry, biochemistry, and thermodynamics with implications for surface waters and ecological systems. Groundwater is also addressed in the context of climate change, agriculture, human health, energy, mining, governance, social sciences, law, philosophy and economics. As such, the GW-Project is multidisciplinary and interdisciplinary. Given the vast breadth of groundwater Topics, the only way to examine, inform, and educate with credibility is to have each Domain planned by a team of experts and each book therein designed and authored by experts on the given Topic.

Scientific and policy controversies exist for many Topics that bear strongly on, or derive from, concerns about groundwater. These include shale development for gas and oil (fracking), deep disposal of radioactive waste, deep well injection of carbon dioxide to combat climate change, use of pesticides and herbicides, as well as chemical versus organic agriculture. To benefit the public, the GW-Project aims to bring together acknowledged experts to provide a credible synthesized and comprehensible presentation of these and other societally important Topics with global scope, subject to rigorous peer review. In situations with more than one credible scientific position, conflicting views will be presented to support credible debates.

A.4 Breaking Away from Convention on a Global Scale

The need for more effective management and protection of groundwater has never been greater. Solutions lie in breaking away from convention by applying the most advanced knowledge through data collection and analysis, using best available and novel methods and procedures that continue to be improved around the globe. The challenge is to identify and make them known and the GW-Project is picking up this challenge.

A key aim of the GW-Project is to use its globally expanding network to seek out and make known the exemplary successes around the globe concerning all things groundwater to inform next steps in knowledge creation and innovations to address our freshwater challenges. This includes the scientific and the technical as well as management and governance. There are large gaps between common and best practices and a goal of the GW-Project is to identify the gaps that are limiting progress so that the immense advances in knowledge over past decades can better serve

A-4 the urgent needs of humanity. We seek participants from all countries around the globe to provide knowledge about groundwater conditions, research, and practices in their countries so that the GW-Project can become a broad window to the global state of groundwater and groundwater knowledge. The GW-Project seeks and synthesizes groundwater excellence from an ever-expanding list of countries around the globe where circumstances have resulted in exceptional approaches or accomplishments. As just a few examples, Denmark, a small country situated on an extensive clay aquitard that protects the bedrock aquifer supplying the entire population with drinking water, does exemplary aquitard research; the Netherlands has an exceptionally effective system of groundwater governance, with origins that go back hundreds of years, that effectively balances the needs of the watershed, the local residents, and the country at large. China is rapidly establishing the world's most advanced groundwater monitoring network using modern technologies providing data in real time. South Africa has a tax on water use with collected funds allocated solely and effectively to water research on long-term continuity. The United States has exceptionally demanding legislation related to groundwater contamination that has forced attention on clean-up, resulting in outstanding examples of groundwater remediation. The City of Guelph, Canada, which relies on groundwater from a fractured rock aquifer is advanced along the path of establishing a modern and comprehensive groundwater monitoring network using advanced multiport systems. Much knowledge about groundwater has been acquired by practitioners in addition to academic or government researchers. These groundwater professionals supervise the drilling of water wells, investigate contaminated sites, and design groundwater extraction, remediation, and monitoring systems. The GW-Project seeks to capture the widely distributed, but largely synthesized knowledge from practitioners in various ways, including case studies aimed at highlighting the key insights gained, the new methods found successful, and the as-yet unanswered questions.

A.5 The Importance of Freshwater System Interfaces

There is immense knowledge in freshwater science with respect to the hydrological cycle and hydrogeochemistry, but generally weak understanding of what happens at the interfaces between the components of the freshwater system. Given that groundwater makes up 99% of all liquid freshwater, groundwater is key to the understanding freshwater as a dynamic system. an aim of the GW-Project is to synthesize interface knowledge.

This weakness in understanding the interfaces is due to the long-established university knowledge disciplines centred on the components and not the interfaces. The interfaces are also fraught with complexity, with key interfaces being those (1) between the land surface on which surface water flows and the soil into which surface water infiltrates; (2) between the with its capillary fringe and the groundwater zone, across which water must pass to recharge the groundwater zone; (3) where water discharges from the groundwater zone into soil, wetlands, streams, rivers, lakes; (4) where chemical and biochemical reactions between water and soil/geological media take place; and (5) between water and biological components of the ecosystem.

A-5 The interfaces are most difficult to study due to rapid changes in time and space. Universities with their traditional disciplines (knowledge realms, e.g., hydrogeology, soil science, hydrology, geochemistry, , engineering, biology) are organized around individual system components to the detriment of understanding overall system behavior; yet such understanding is most important with respect to how human activities are changing the system and to predicting future consequences. Many elaborate mathematical models can simulate the freshwater system but have limited capabilities for representing long-term system behaviour in response to human activities because of poor understanding and monitoring of the interfaces. Governance encompasses philosophy, economics, law, ethics, sociology, political science, and psychology. In universities, these disciplines are housed in different departments, buildings, and faculties with minimal dialog and research and education at disciplinary interfaces. These obstacles and deficiencies have been recognized to affect the understanding of groundwater in the dynamic freshwater cycle, but little has been done to address this shortfall. To be effective, the GW-Project strives to shine light on the interfaces and overcome discipline dialog barriers. The GW-Project has as its primary goal the creation and dissemination of knowledge to serve humanity and therefore must seek ways to reduce the barriers to synthesis of knowledge at the interfaces and seek to make knowledge from groundwater science and engineering available to be incorporated in governance. To create synthesized knowledge across disciplinary interfaces, the GW-Project is encouraging interdisciplinary co-authorships to promote critical thinking at the interfaces. To this end, the GW-Project intends to organize meetings (virtual and/or real) to facilitate the creation of synthesized knowledge at the scientific and disciplinary interfaces most important to groundwater.

A.6 The GW-Project in the Context of Developing Countries

“Knowledge is power. Information is liberating. Education is the premise of progress, in every society, in every family.” — Kofi Annan, 1997

In 1990, the United Nations and World Health Organization reported that 2.1 billion of the Earth’s inhabitants lived without access to safe drinking water. In 2015 it was announced that the number of people without ‘improved” drinking water sources had dropped to less than 700 million. This categorization of ‘improved’ water supply was problematic because follow-up studies showed what were deemed ‘improvements’ did not protect water sources from excessive bacterial contamination, as indicated by E. coli and Total Coliform bacteria counts. These are indicator parameters for many other water pathogens including viruses. The number of people with ‘unsafe’ drinking water is therefore still about 2 billion.

The UN Secretary-General's message on World Water Day (March 22, 2019) stated that 2.1 billion people live without safe water, and that growing demands, coupled with poor management, have increased water stress in many parts of the world. Climate change is adding dramatically to the pressure, and by 2030, an estimated 700 million people worldwide could be displaced by intense water scarcity.

A-6 Because most of the world's surface water bodies are over-exploited, excessively contaminated, or both, the only option left for provision of safe drinking water in most developing countries is groundwater. Most of the 3 billion people who are going to be added to the global population in the next three decades will need to access groundwater for their drinking water supply. One reason why the effort to greatly reduce the number of people without safe drinking water has failed is inadequate knowledge and technical resources to effectively search for and protect groundwater resources and/or utilize appropriate water-well drilling tools and pumps. Much of the groundwater exploration work completed to date has been focused in the developed world. However, much work still needs to be done to assess and map aquifers in developing countries to identify drinking water supplies. Most developing countries have studied their largest aquifers, but not adequately delineated small aquifer systems that are key for evaluating water supplies for villages and farms. Mountain hydrogeology, including springs and seeps, is important because more than half a billion people in the developing world live on or near mountain slopes, often steep slopes, and cultivate crops in fertile valleys supplied with mountain water. Most non-replenishable fossil or ancient groundwater occurs in developing countries and this important resource, which is very large in some regions, requires careful monitoring and management. Specific challenges must be addressed when using groundwater resources in the developing world. The vast majority of these communities obtain their water from groundwater (via wells, springs and mountain streams) and dispose of their waste locally (via latrines) without water or sewage treatment plants. The effectiveness and sustainability of these water and sanitation systems depends upon the ability of those involved to find and extract groundwater, protect it from being polluted by latrines, agricultural, and other land-use, and prevent decreased recharge to groundwater as a result of deforestation. The GW-Project touches on each of these topics to help address water supply challenges in the developing world.

A-7 The GW-Project is covering many topics especially relevant to developing countries, including:

1. Exploration for Groundwater 7. Development and Management of Fossil Resources Groundwater Aquifers 2. Mountain Hydrogeology and Springs 8. Sources and Migration of Pathogens for Water Supply 9. Groundwater Arsenic and Fluoride

3. Land Subsidence 10. Groundwater and Mining 4. Landslides 11. Groundwater and Agriculture

5. Soil Salinity 12. WASH (community water, sanitation, & 6. Peat and Deforestation hygiene)

The GW-Project comes at an opportune time to make important contributions because cell phones and the internet have spread widely into poor regions around the globe. The penetration of these advanced technologies into the poor areas of developing countries has far exceeded the penetration of groundwater knowledge and the methods needed to develop safe drinking water from groundwater sources. Some members of the communities have sufficient education to use knowledge from the GW-Project, but do not have access to study materials in their country or access to online books and journals. A key aim of the GW-Project is to foster rapid dissemination of knowledge and methods to remote areas. Many universities in developing countries are striving to provide education about groundwater and an objective of the GW-Project is to be the essential source of teaching material for these universities.

A-8 Appendix B: The GW-Project Contributions to Education

B.1 Towards a New Approach to Groundwater Education

In the traditional approach to groundwater education, the instructor invests most of his/her time in preparing and delivering the course materials and testing and marking for grades. The testing and marking are done to push the students to learn the prescribed materials. The criticism now commonly directed at this approach to university education is that it lacks in experiential learning and therefore overall is ineffective at best or inefficient at worst.

An aim of the GW-Project is:

✓ To establish excellent synthesized knowledge that is developed and peer-reviewed by experts in each topic area. This is the knowledge that students are to strive to understand. ✓ To move towards learning modules so that all of the basic materials can be self-learned by students with effective self-testing along the way. The learning modules provided by the Khan Academy are examples of effective modularized non-classroom teaching. The objective of the GW-Project with respect to university education is twofold: to achieve more effective learning and to free up time for instructors to engage the students in experiential learning, which requires hands-on lab experiments, field activities, and active modeling exercises. The GW-Project:

✓ Prepares the equivalent of textbook chapters but with more detail, examples, and exercises than typical textbooks. ✓ Will develops a tool for instructors to use to create a "map" of books and associated online materials for students suited to specific courses. ✓ Will seek instructors who want to select from the materials and create “templates” for those who would prefer a predefined course map. ✓ Will prepare learning modules and videos and is seeking advice and examples of effective field and laboratory exercises aimed at engaging students in hands-on activities (through e.g., on-campus groundwater monitoring facility and well drilling activities). For academics, the GW-Project is providing a new form of publication outlet. Academics are at present held prisoner to the peer-reviewed journal process that has established journal citations as the key measure of research productivity and value based on the citation numbers. Most or perhaps nearly all financial support and facilities used for groundwater research is based on the premise that the research will benefit societal needs. Minimal support is provided for addressing questions of pure scientific interest separate from societal relevance. Therefore, judgement of research value based on peer-reviewed citations is problematic and instead should be based on two criteria: (1) the degree to which it advances the science; and (2) the degree to which the work is synthesized and made available to serve society.

B-1 . The GW-Project is aimed at the second criterion and the main measure of success will be downloads of the published materials and other forms of feedback to the GW-Project on the published materials. In addition, the GW-Project is providing publication opportunities for materials that lack other publication opportunities. A parallel track of materials is being prepared aimed at readership that is not formally educated in groundwater science or a related engineering field, in addition to and general readership including private well owners, non-governmental organizations, environmental groups, high school educators, etc., with the goal of raising global groundwater consciousness, and providing a wide range of materials to this readership. These materials will also include learning modules for high school students and groundwater books for children to teach our youngest members of society about the importance of groundwater.

B.2 Groundwater Teaching at the University Level

Teaching of groundwater in most universities is done in geoscience/earth science or civil/environmental engineering departments and seldom examines the depth and scope of groundwater science. Typically, one or two courses at the undergraduate and master’s level are offered. The undergraduate level commonly features is an introductory groundwater course for geoscientists and another for engineers; offering much more would require more groundwater- focused faculty and room in the curriculum for more groundwater courses. However, many universities have only one token groundwater professor and therefore course offerings are minimal relative to what is being prepared by the GW-Project as suitable for university level education and to what is needed by society to have groundwater issues adequately addressed.

In the GW-Project, the university sector is an important component in the overall education philosophy that includes continuing education for professionals and high school education. However, this section is only concerned with the university sector, to explain the role of GW-Project to our colleagues in academia. The GW-Project aims at providing what is needed for anyone to understand ‘all things groundwater’ and will provide a more integrated view of groundwater and less of the traditional discipline siloing of education. The GW-Project recognizes that groundwater education needs new approaches to learning that are in sync with the way our future generation of students learns. This requires an educational environment that promotes self-learning, solving case-studies independently, and hands-on experience with science. The GW-Project is aiming for both broad and deep coverage with the hope that universities around the world will recognize the disservice they are doing to society by trivializing groundwater science. This trivializing means students who graduate from “groundwater programs’ are led to believe they have learned a substantial amount about groundwater science when they likely have not been exposed to the full range of topics within groundwater science. We expect that the GW-Project will provide significant breadth of knowledge that will serve graduate students in their research and adequately prepare students for the demands of the groundwater sector (whether that may be pursuing a career in science, consulting, or governance).

B-2 For the purpose of “education in the university context”, the GW-Project is focusing on seven pillars, detailed below, that ultimately feed into the 23 Domains (Figure 1):

Figure 1: The Domains of the GW-Project cover the needed knowledge base for a well-rounded groundwater university education. The books published in the various domains will collectively cover the seven pillars.

Pillar 1: Physical Hydrogeology and Hydrology The GW-Project will publish a dozen of books in August which encompass what is typically taught in the undergraduate and early graduate courses in this pillar. However, the coverage will far exceed what is taught in any one or two courses and therefore university course instructors will have significant material to select from and the students will be able to see what additional material is available. Addition to publishing material within what can be termed the “porous media topic segment”, the GW-Project aims to provide good coverage of fractured rock, karst, and groundwater-focused watershed hydrology, topics of which are rare at universities, yet half of the world’s population relies on these systems for water.

Pillar 2: Groundwater Geochemistry Groundwater geochemistry is needed as foundational knowledge for understanding groundwater contamination, general water quality, and better understanding of groundwater flow systems. The GW-Project includes a plan to prepare about 20 books covering nearly all relevant topics needed to understand the principles of groundwater geochemistry including freshwater, brackish water, and brines. This knowledge is needed to understand the many application areas, such as the effects of mining on groundwater and surface water, fracking, and more. This suite of books being prepared aims to address this area of university teaching, acknowledging the lack of market for such courses due the limited instructors with appropriate expertise and limited space in established curricula in geoscience and engineering.

Pillar 3: Groundwater Contamination The university sector generally acknowledges that groundwater contamination is a topic that should be covered to a useful degree but often only have a course or maybe two on this topic. More than a dozen of books pertaining to this pillar are being prepared. These materials will cover the general nature and history of groundwater contamination and explain transport and fate processes of both non-reactive and reactive solutes, including modeled and field examples of a variety of contaminant plumes. By the end of 2020, we expect to have useful coverage of the

B-3 materials needed to teach at the undergraduate and early graduate level based on what is currently covered at most universities. By the end of 2021, we expect to have good coverage for understanding of transport and fate.

Pillar 4: Groundwater Remediation Some aspects of groundwater remediation are being taught in engineering at universities and the GW-Project plans to cover all aspects of remediation in the groundwater context with emphasis on how geology, hydrogeology, and geochemistry play important roles. Work on this part of the GW-Project has not yet begun due to the need to substantially develop coverage of geology and fate and transport, as remediation is founded on this knowledge. The goal of the GW-Project is to show how and why these fundamentals are needed to select, design, and apply groundwater remediation more effectively. The GW-Project also plans to make contributions to the topic of natural attenuation of groundwater contamination, and present knowledge at the interface between groundwater science and engineering.

Pillar 5: Groundwater and Society Groundwater problems have grown to crisis proportions in many parts of the globe, including too little groundwater use in many poor countries. In many cases, this is not for lack of groundwater scientific and engineering knowledge but due to limitations inherent in water and land governance that derive from many factors including economics, understanding of groundwater effects on human health and related risk issues, sociology, philosophy, and law. The academic literature currently reflects few communications between the groundwater science and engineering disciplines and the those indicated above in the governance context. An objective of the GW- Project is to bridge the two philosophies in the groundwater context. Materials for this Pillar will be prepared by experts in governance, economics, law, etc. The aim is for these experts to write for non-expert readers in their expertise areas. This will provide an excellent induction to the integrated view of groundwater for students in science and engineering.

Pillar 6: Groundwater and Ecological Systems A premise of the GW-Project is the notion of many ecological systems that are substantially groundwater dependent. This premise is based on the fact that groundwater represents 99% of all freshwater and therefore many ecological systems are bathed in groundwater continually or temporally. The paucity of teaching and research concerning groundwater and ecological systems is an undesirable situation because land use changes, groundwater depletion, and groundwater contamination are resulting in changes in ecological conditions in many locations that are going unmonitored and unstudied. Few researchers around the globe have expertise in this topic area. An aim is to assemble enough materials to support university courses about the role of groundwater in ecological systems and stimulate graduate student research in this area.

Pillar 7: Research Approaches, Methods, and Techniques

University teaching of groundwater is limited relative to the actual scope and depth of the groundwater science. Therefore, much of the material that will soon be published in the GW- Project will not contribute directly as course materials. The GW-Project will, however, have a large amount of synthesized knowledge that will serve to help identify research topics and facilitate

B-4 research. One notable benefit of aiming to cover a wide range of topics and synthesize what is known is identifying what is not known and may be of importance. Books will also be devoted to the applications of particular research approaches to answer questions. The GW-Project is endeavoring to include as much material as possible about research methods and techniques to capture the experience of successful groundwater researchers and thus help new researchers.

B.3 Educational Groundwater Simulations

Conventional textbooks about groundwater typically have many diagrams but few created for the specific purpose of the textbook; rather, most diagrams/figures are taken or adapted from the published literature. Modeling is essential for the science to make progress but has not been well adopted for groundwater education. The GW-Project takes on the premise that modeling and simulation are essential for both science and education.

Simulations are ideal for explaining how and when parameters and boundary conditions control the character of groundwater systems. Simulations serve to show the influence on the groundwater system of parameters considered one at a time. The GW-Project will:

✓ Use mathematical models to create figures based on simulated scenarios to explain and illustrate the role of parameters and boundary conditions for many of the processes involved in groundwater systems. ✓ Use models to help students to develop intuition about groundwater systems and encourage data interpretation skills. ✓ Use models to help students to develop intuition about groundwater systems and encourage data interpretation skills. ✓ Use simulations to enhance understanding through videos. ✓ Provide directly, or link to, public domain software so that students can expand their options for using models for understanding and research. The aim of making strong use of simulations in the educational process is to show how groundwater systems function as well as how models are used to achieve understanding. This will be done by integrating simulations into many books and by providing an entire Domain focused on mathematical models as tools for solving groundwater problems. Generally, the state of knowledge of any particular aspect of groundwater science is contained in the degree to which we are able to explain our conceptual models, based initially on observed phenomena, through simulations. Although reliance on simulations will markedly contribute to educational materials in Domain 2, the GW-Project as a whole will emphasize the nature and role of the data that underpin the understanding of groundwater systems. Field and laboratory data must be used in concert with mathematical models to advance the science as interacting, interdependent realms of the scientific process.

B-5 B.4 Experiential Learning in the GW-Project: Field Exercises on or near Campus

The GW-Project is aimed at groundwater education through the provision of five main types of learning materials: (1) The books with their exercises and associated learning aids such as videos; (2) Packages learning modules, e.g.: YouTube, Khan Academy; (3) Case studies that emphasize learning; (4) Packaged entire courses as offered by instructors around the globe at their universities; and (5) “On campus” field activities and exercises as outlined here. The GW-Project has as one of its objectives to show how wells and piezometers can be installed at lowest cost in just about any type of terrain to create a network for field tests wells and sampling well to acquire different types of data to underpin learning about groundwater geology, flow systems, groundwater geochemistry, groundwater contamination and groundwater geophysics. This can be accomplished by use of small low-cost drilling machines (e.g.: less than USD 10K). The GW-Project is currently testing such drills and well installations at the University of Guelph, Canada and Mercer University, USA, to assess their suitability for this educational purpose. In this vision, it should be feasible for each university that offers or wants to offer substantial groundwater education to establish a groundwater learning facility on campus or near campus in parkland, open land or even parking lots that can be used for field exercises in a few types of courses. There are now low cost down-hole electronic devices that can be used to record water pressure and temperature so that what is happening in the groundwater zone on campus can be transmitted to the student body in real time. There are also low-cost multi-depth monitoring systems that can be used in such learning networks to enhance learning about groundwater systems in 3-D. These can also be installed to substantial depth using simple low-cost drills. In the developing countries manual drilling methods are also used to create water wells; of low cost and made of local materials (costing less than USD 1000). Some are sophisticated drilling methods (machines) and can drill to substantial depth. These methods are suitable for making ‘on campus’ wells in developing and developed countries because much is learned about the geology and drilling principles when sophisticated drilling methods are used. Another principle that can be learned concerns what can be done using appropriate technology rather than seeking the ‘highest technology’. There are now small groups operating on various campuses that design and assemble pressure transducers and temperature measurement devices at low cost because the components for these devices have become so inexpensive. These groups provide design and assembly instructions so that this can be incorporated into the learning process for groundwater students. The GW-Project is seeking universities to engage in a global demonstration project to use the smallest but effective low-cost powered drills and manual drilling methods to establish ‘on campus/near campus’ groundwater observatories for experiential learning. On some campuses, funding is available to drill deeper wells so that the observatory is more exclusive of the hydrogeology. The overarching aim of the GW-Project is to promote groundwater consciousness and the logical starting point is for groundwater students at all universities that teach groundwater “hands-on”, to know the groundwater conditions beneath their feet and for there to be on-campus posters that describe for all students to see-what is beneath their feet but out of site.

B-6 B.5 Learning Support Materials

The following is a list of examples of potential learning support materials to be created and disseminated through the GW-Project.

▪ Video lectures along with tests and other ▪ Problem assignments with worked supporting material available to use as answers and with answers provided but course material not worked out ▪ Video lectures on single Topics (e.g., ▪ Links to open source software dispersion, anisotropy, heterogeneity, ▪ Links to selected free articles, old sorption) literature, reports ▪ Hydrogeology information for each ▪ Case studies: geological conceptual country so that course instructors can model creation relate the more generic materials in the ▪ Case studies of groundwater resource books to their location development ▪ Step-by-step derivations of equations with ▪ Case studies of contaminated site associated explanations and guidance characterization ▪ Video recorded laboratory demonstrations ▪ Case studies of contaminated site using sand columns and text boxes remediation ▪ Hele Shaw models ▪ Case studies: investigation ▪ Educational computer simulations: flow methods/tools and transport ▪ Synthetic case examples illustrating ▪ Field Videos: drilling, sampling, well calculation procedures and modelling installations ▪ Case studies to show different ▪ Step-by-step descriptions to draw contour processes/outcomes and isopach maps, cross sections, fence ▪ Annotated course notes provided by diagrams instructors

B-7 Appendix C: Organization of GW-Project Domains

Scope of GW-Project Publications

With the aim of raising groundwater consciousness globally, the GW-Project is publishing books in four categories:

1. Children’s Books - dedicated to all sorts of groundwater information for children; designated as Domain A Books. 2. Introductory Books - covers a wide range of groundwater topics, written for a broad audience; designated as Domain B Books. 3. Overview Books – comprehensive books which cover groundwater topics in a larger context in a descriptive manner (mostly without equations); designated as Domain C Books. 4. Specialized Books – primarily tailored towards groundwater education at the university level and continuing education for groundwater professionals; designated as Domains D through W Books.

Domain A: Groundwater Information for Children

This domain focusses on educational information tailored towards children, including elementary school level education. Is includes short books, stories, drawings, coloring plates, animations etc. We have already published on our website the decades-old children’s book Wally and Deanna’s Groundwater Adventure by Leanne Appleby and Peter Russell(also available in Spanish and Greek translations), with more books to follow. Through the colourful books and related materials, we endeavour to create awareness among the young ones about the importance of groundwater in a creative way.

Domain B: An Introduction to Groundwater

This Domain is designed for a wide readership, and includes various groundwater topics, including concepts and terminologies, groundwater quality and protection, groundwater development (the drilling of wells), information for domestic well owners, and various groundwater issues in modern times. Much of this Domain is also useful in education at high school levels to create awareness of the central role of groundwater in supporting humans and ecosystems. A key point of this Domain is that groundwater is everywhere beneath us and connects to the rest of Earth’s freshwater in ways that all humans can, and need to, appreciate to be better citizens of the Planet.

C-1 . Domain C: Groundwater Overview Books

These books cover broad topics written for readers who have a general interest in groundwater science. The books are mostly without equations but with abundant schematic figures, simplified maps, cross sections, charts, tables to go along and with explanations of scientific and technical terminology and the related scientific processes and concepts. The first published book of this Domain is Groundwater in the Water Cycle: Getting to Know the Earth's Most Important Freshwater Source by Poeter et al., and other book topics are (to name a few): large aquifer systems around the world, groundwater in early human societies, a global view on groundwater pollution, groundwater and human health, and groundwater and climate.

Domain D: Groundwater Processes: Physical, Chemical and Biological

These books cover basic concepts and processes with teaching modules to understand groundwater flow, groundwater geochemistry, groundwater contamination, groundwater microbiology and ecohydrogeology as needed for university-level teaching through the Masters (MSc) level for porous and fractured media and karst. This Domain provides the essentials needed for reading nearly all of the other books in the GW-Project, except for the subjects in the social sciences/ governance. This Domain includes basic education in the groundwater relevant aspects of fluid mechanics, inorganic and organic chemistry and biology and numerical simulations are used as an important way of education about the influence of processes.

Domain E: Groundwater Geology

These books cover groundwater occurrence and characteristic hydrogeologic features in various types of geology: non-indurated deposits of glaciers, rivers, lakes, wind and weathered bedrock (e.g.: laterite) in the form of aquifers, aquitards and transitional hydrogeologic units, sedimentary, igneous and metamorphic rocks including how fractures impart permeability and fracture porosity, roles of faults in permeability and flow systems. Knowledge of how geology including weathering and chemical precipitates provide expectations about the nature, continuity and distributions of hydraulic and chemical properties. For prerequisite geological knowledge students are referred to online geology courses and public domain books.

Domain F: Natural Groundwater Systems in Different Terrain and Climatic Settings

These books pertain to manifestations of natural flow systems in combinations of geology, climate and topography to illustrate governing influences on system characteristics such as the flow patterns, hydrogeochemistry and groundwater residence time distributions. Groundwater flow systems are everywhere but few have been studied well enough for the characteristics and controlling factors to be well understood and therefore the challenge in preparing these books is selection of the best examples from around the world ranging between tropical and desert climate regions to show how the various lines of evidence (geology, head, geochemistry, isotopes, temperature) result in the conceptual model or models for the flow systems.

C-2 Domain G: Groundwater Resources: Assessment, Extraction, Conjunctive Use and Impacts

These books explain how to find and assess groundwater resources and integrate groundwater exploitation into beneficial uses including Managed Aquifer Recharge (MAR). This includes how natural and induced recharge relates to sustainability and how understanding aquitards is essential for sustainable water development. This Domain includes advanced methods to analyze hydraulic test data for groundwater resource understanding and elucidates adverse effects of groundwater extraction including land subsidence, reduction of flow into streams, lakes and wetlands, and saltwater intrusion. The amount of water pumped from aquifers is generally known, but where the pumped water comes from needs explanation.

Domain H: Groundwater Contamination and Aquifer Vulnerability

These books rely on the fundamentals of transport and fate presented in Domain C to look at contamination caused by landfills, septic systems, leaky sewers, petroleum products, DNAPLs, pharmaceuticals, flame retardants, road salting, latrines and graveyards. In developing countries, bacteria and viruses are common in well water so this contamination is addressed in detail. Avoiding contamination is best so this Domain examines ways to assess aquifer vulnerability, which is challenging due to the large range in hydrogeological conditions and contaminant types. The groundwater contamination literature is larger than for other Domains and the aim is synthesis of his diverse and fragmented literature into a consistent whole.

Domain I: Groundwater Protection, Remediation and Contaminated Site Management

These books examine the strategies, approaches and technologies for remediation and management of contaminated sites with consideration of contaminant sources zones and plumes including active plume controls, remediation and natural attenuation and groundwater quality protection. This includes consideration of ways to assess groundwater vulnerability and designate and manage land use to minimize groundwater contamination. There is much complexity involved because different types of contaminants have such different propensities to cause contamination in the different categories of hydrogeologic conditions such as for unconsolidated geological deposits versus fractured bedrock versus karst.

Domain J: Subsurface Intrusions from Human Activities

These books are concerned with how subsurface engineered intrusions serving societal need, and impact groundwater and presents approaches to reducing negative impacts. Cavities are needed for mining, quarrying, tunneling, sewage piping, underground trains/subways, and deep radioactive waste repositories. Intrusions associated with energy industries include conventional petroleum wells, fracking, injection of liquid wastes, injection of liquidized carbon dioxide to combat climate change, and extractions of heat and hot water for geothermal energy. Each intrusion creates perturbations in the groundwater system that may result in excessive groundwater inflow to mines or tunnels requiring grouting or design changes.

C-3 Domain K: Groundwater and Human Health

These books draw on collaboration between the groundwater science and public health communities and focus on how groundwater quality dependent on natural and anthropogenic chemicals and pathogens can impact human health. This Domain explains how regulatory levels are established with their uncertainties. The epidemiological methodology used to assess cancer clusters is examined in the context of groundwater contamination science. Pathogenic bacteria and viruses in groundwater commonly cause of human illness but is often difficult to connect to groundwater causes. The longevity of virus activity under groundwater conditions are common water tests for pathogens (e.g.: E. coli and Total Coliform).

Domain L: Groundwater in Development and WaSH (Water, Sanitation, and Hygiene)

These books are aimed at the needs of a billion people, rural and urban, in the world‘s poorest countries and in poor aboriginal areas of developed countries, with emphasis on selecting locations for and creation of safe drinking water wells for families and larger ones for villages using appropriate (not-complex, low cost) technologies, including manual drilling and engine powered drills suitable for ‘self-supply’ and latrine design and locating to avoid contamination. Many water sources in the poorest countries are unsafe due to pathogens, which can be reduced by better well designs with better sanitary seals. This Domain includes pathogens testing, pump technologies, rainwater harvesting for recharge and interfaces with appropriate agriculture.

Domain M: Role of Groundwater in Geologic Processes and Hazards

The books concern groundwater as an important agent in the formation of landscape and soil as it continually dissolves and transports minerals and associated reaction products to discharge points. Therefore, over geologic time, groundwater is an agent in eroding the landscape from within, which weakens the subsurface; the ultimate example is karst terrain, where dissolution of the carbonate bedrock causes land surface subsidence or collapse. In short, groundwater plays a role in geomorphology. The distribution of groundwater pressure can weaken terrain, contributing to erosion. Stability of slopes largely depends on groundwater pressure distribution and can trigger landslides, and groundwater pressure is involved in earthquakes.

Domain N: Groundwater and Ecosystems

These books concern groundwater-dependent ecosystems sustained or influenced by groundwater such as streams, rivers, lakes, marshes, swamps, and bogs where groundwater largely governs the temperature and hydrochemistry of the ecosystem. This Topic is introduced in Doman C to understand the processes by which groundwater plays a role in ecosystems whereas Domain M examines impacts of human alterations of groundwater flow and chemistry on natural ecosystems and presents examples of mitigation measures. This Domain addresses how groundwater-dependent ecosystems play a role in the fate of contaminants such as removal of contaminants and degradation of the contaminants in engineered wetlands.

C-4 Domain O: Groundwater Occurrence and Importance Country by Country across the Globe

This Domain presents the important and noteworthy information about groundwater in each country of the world so that the GW-Project can provide a comprehensive worldview. The aim is to summarize what is known, unknown, and being investigated most or deserves attention in the future. The information about each country includes groundwater governance and factual information about groundwater quality, how much groundwater is used, where, when, and what for, and the uncertainties and trends in the numbers; therefore, when all countries are accounted for the global situation concerning groundwater will be far better known than is now the case. The GW-Project aims for collaborations around the globe to include all countries.

Domain P: Evolution of Groundwater Knowledge and Research Approaches and Strategies

For some groundwater Topics, knowledge is well advanced or mature; for other Topics, little is known relative to what is needed to effectively manage and protect groundwater through science- informed decisions. This Domain examines the state of groundwater science for various topics including what underpins the science. To understand the knowledge state of any Topic, we need to examine how the knowledge evolved. This Domain also examines the administrative structures for research and differing approaches in various countries to what has worked most effectively. Many groundwater problems are in much need of innovation and therefore finding and reducing impediments to innovation is urgent.

Domain Q: Groundwater and Society: Social Sciences, Economics, Law and Governance

The books concern the interfaces between groundwater/engineering and the various other disciplines that relate to groundwater governance including law, philosophy, ethics, sociology, political science, psychology and economics. This Domain seeks contributions resulting from cross disciplinary dialog and interdisciplinary collaborations that synthesize information from many disciplines to be understandable to all. This Domain seeks to identify and examine the best examples of successful groundwater governance that have broad relevance and economic models aimed at sustainable use of groundwater. Groundwater depletion and pollution is tragedy of the commons and this Domain seeks to provide knowledge and reasoning for solutions.

Domain R: Groundwater and Agriculture

These books cover how agriculture uses and impacts groundwater. Agriculture is by far the largest groundwater user and is the main cause of the severe depletion and pollution of groundwater, the combined effects of which are the most important contributor to diminishing prospects for human habitation and ecological systems on Planet Earth without extreme suffering. Coverage is aimed at examining differences in impacts between chemical agriculture with reliance on large machinery and the various approaches to ecological agriculture (e.g.: organic, bio-dynamic, etc.), how agriculture influences soil carbon, water retention and infiltration capacity, and how these relate to recharge, runoff causing floods, groundwater depletion and sea level rise.

C-5 Domain S: Topics Not Well-Suited for Conventional Publishing

Scientific research can show significant advances not well-suited for publication in peer-reviewed journals. Conclusions may be too speculative, or the topic lacks perceived relevance to journal readership, or too far ahead of convention. The GW-Project will publish selected works of this nature after rigorous peer-review and welcomes works from experts on emerging topics, or topics considered too immature by peer-reviewed journals, to be ahead of potential problems rather than behind so problem surprises are avoided. We are inviting the world’s accomplished in the senior generation for contributions about whatever they choose to capture views of those who have acquired a lifetime of experience concerning groundwater.

Domain T: Case Studies

These books present valuable insights from practitioners who relay their findings using case studies focused on ‘lessons learned,’ which are essential for tying education to the working experience of answering questions and solving problems. The focus is on useful real-world examples with their inherent complexity and uncertainties in which the principles and concepts presented in other Domains are applied with emphasis on how problems are identified and formed into questions that enable effective investigations to be conducted. To answer questions along the path to solving groundwater problems, many methods and tools are available for which case studies are needed to show how they can be used effectively.

Domain U: How to Do Things: Methods, Equipment, Tools, Procedures, Models and Software

Ultimately, the degree to which we can make scientifically informed decisions concerning groundwater depends on our ability to acquire data relevant to the problem and, because groundwater is hidden beneath the surface, selection of what is the most effective or efficient methods and tools to acquire the essential data is commonly problematic. This Domain is aimed at making available information on everything that can help those engaged in solving groundwater problems do so more effectively based on the premise that “the devil is in the details”. This Domain will rely on providing detailed design information and videos showing how things are done and how software is used and on answering the common questions.

Domain V: Groundwater Education and Professional Qualifications around the World

This Domain is aimed at identifying, organizing and presenting the nature and characteristics of groundwater education in universities around the world with emphasis on identifying what is considered to be essential knowledge in the educational process with the variations that result from regional conditions and history. It will seek out examples of where and how groundwater science is taught at the high school and elementary levels to foster this globally. Also, this Domain will examine the requirements for professional qualifications and certification for practice in groundwater science and engineering with focus on what is exemplary for advancement of groundwater wellbeing to serve societal and ecological needs.

C-6 Domain W: Miscellaneous Educational Support: Annotated Course Notes, Video Lectures, Demonstrations and Archiving Documents

The materials support learning and application of knowledge that may not fit well in the other Domains such as some: (i) video lectures; (ii) videos of laboratory demonstrations; (iii) annotated course notes that cross Domains or disciplines; (iv) annotated photographs and videos of groundwater features such as springs, artesian blow outs, fractures, salt accumulations, flowing wells, groundwater-dependent vegetation; photography in caverns and tunnels and excavations showing features relevant to hydrogeologic parameters or processes; (v) documentary films no longer available; (vi) archiving reports and books that need to be made known to the youngster generations; and (vii) write-ups and items relevant to groundwater history.

C-7 Appendix D: The GW-Project Direction and Management

The initial thinking about the vision for the GW-Project as a large global endeavor to educate broadly about groundwater for a vast and diverse readership started in 2016 with Dr. John Cherry proposing a vague vision to a few close colleagues who were positive to the idea. This led to the establishment of a committee, now called the Steering Committee, to advise frequently on how to proceed. Dr. Cherry began to invite senior colleagues to prepare book chapters in their expertise areas and by fall, 2017, a few dozen colleagues around the globe had committed to contribute books, enough for the vision to take on some credibility.

Dr. Cherry is the Steering Committee Chair and Project Leader. The Steering Committee became a more formal managing entity in 2018 with two members of this Committee taking on exceptional responsibilities: in effect but without titles, Dr. Eileen Poeter became the ‘managing director’ and Dr. Everton de Oliveira became responsible for the web publishing process and GW-Project publicity. Also, the Steering Committee was expanded from its initial 5 members to its present 11 members. A Project Coordinator (Amanda Sills, MSc) was hired part time in late 2018 with funds from early donations and support from the G360 Institute for Groundwater Research at the University of Guelph. In early 2020, Dr. Ineke Kalwij joined the Steering Committee and took on the lead for the ‘lay persons and high school’ education part of the Project and assisting with the project management. In the summer of 2020, Dr. Paul Hsieh joined the Steering Committee to take the lead in the development and management of the GW-Project website.

When larger funding becomes available, additional project coordination support is the highest priority because at present the limiting factor in the communications and production of books is the processing of manuscripts through the rigorous multi-stage peer review process.

The management and direction of the GW-Project is virtual; there have been no face-to-face group meetings although Dr. Cherry has met with all members of the Steering Committee. There are weekly and often daily communications within the Steering Committee. The GW-Project is managed by consensus with Dr. Cherry leading. With this low-cost and informal management approach relying on volunteerism, cooperation and collaboration.

There is also an Advisory Committee with 13 members, each member is participating in the GW-Project in one way or another, including participation in preparation of books, review of book drafts, and responding to requests for advice or fundraising. However, this committee was not activated to function as a whole as a formal advisory entity. This is planned for the future along with the addition of a few more members for broader geographic distribution and scope.

Dr. Cherry is committed to continue in his current role for the next two years and the makeup of the Steering Committee is expected to remain the same with possibilities for minor changes.
