“…There are few agreements for this theme [12], which has been approached through regional and international agreements as a way to deepen its treatment and guarantee that the governance and management of resources fit themselves to the global molds current to the theme [5] [6]. The formal and informal arrangements have been models to the dealing of the issue [13].…”

It is a huge reserve in South America region and it is considered one of the largest sources of groundwater on the planet. The GAS has strategic value for its countries, especially in a context of increasing scarcity. Its size, its physical and political complexity, as well as its "invisibility" and insufficient treatment in the international scenario, constitute some of the challenging elements for management. The article will, in the first instance, summarize the management cases for transboundary aquifers in the world. Subsequently, a physical and political characterization of the GAS will be made, so that, finally, the existing challenges for the management of this resource will be presented. In order to carry out this work, a bibliographical review of the articles and documents published in recent years concerning the management of transboundary aquifers in the world was carried out, as was done with respect to the Guarani Aquifer and its international framework.

“…One rationale for this approach is to understand our students' knowledge base and how that differs from the scientific knowledge that people need to make informed decisions about water-related issues (e.g., town planning boards, community referenda). Specifically, management of freshwater resources, such as the High Plains aquifer of North America and the Guarani Aquifer of South America, require understanding and cooperation that crosses political boarders [9][10][11]. The goal of this study was to assess undergraduate students' conceptual understanding of fluid dynamics (e.g., velocity, flow direction) in rivers and groundwater using diagrams, a largely unexplored aspect of water literacy.…”

Given the importance of fresh water, we investigated undergraduate students’ understanding of water flow and its consequences. We probed introductory geology students’ pre-instruction knowledge using a classroom management system at two large research-intensive universities. Open-ended clicker questions, where students click directly on diagrams using their smart device (e.g., cell phone, tablet) to respond, probed students’ predictions about: (1) groundwater movement and (2) velocity and erosion in a river channel. Approximately one-third of students correctly identified groundwater flow as having lateral and vertical components; however, the same number of students identified only vertical components to flow despite the diagram depicting enough topographic gradient for lateral flow. For rivers depicted as having a straight channel, students correctly identified zones of high velocity. However, for curved river channels, students incorrectly identified the inside of the bend as the location of greatest erosion and highest velocity. Systematic errors suggest that students have mental models of water flow that are not consistent with fluid dynamics. The use of students’ open-ended clicks to reveal common errors provided an efficient tool to identify conceptual challenges associated with the complex spatial and temporal processes that govern water movement in the Earth system.

“…In the U.S., research related to groundwater governance and management in the 50 U.S. states is limited. Other analyses have focused on the watershed scale e.g., [23][24][25][26][27], the regional scale [19,28,29], or internationally-shared watersheds e.g., [18,20,[30][31][32]. Though some research has been conducted on state-level groundwater governance and management in the U.S. [33][34][35][36], few researchers have examined water governance and management at the state level, despite the fact that most governance strategies and management actions are focused at this level.…”

Critical Issues Affecting Groundwater Quality Governance and Management in the United States

Groundwater is increasingly important for meeting water demand across the United States (U.S.). Forward thinking governance and effective management are necessary for its sustainable use. In the U.S., state governments are primarily responsible for groundwater governance (i.e., making laws, policies, and regulations) and management (i.e., implementation of laws, policies, and regulations). This decentralized system results in diverse strategies and practices. We surveyed a water quality professional from each state to better understand commonalities and differences across states. These professionals identify a wide assortment of groundwater issues and concerns, including quality and quantity impairment, staffing and budget issues, private well vulnerability, and overdraft. Respondents indicate contamination problems from natural and anthropogenic sources. Most respondents report that their states have significantly changed groundwater quality policy during the past 30 years. While most states have multiple funding sources for water quality programs, program budgets have decreased in the last decade, thereby hindering effective implementation of new policies. Over half of respondents indicate that water-quality/water-level monitoring and increased groundwater pumping will require more attention over the next decade. Several respondents anticipate groundwater regulation changes in the next five years. We discuss how our findings align with current groundwater uses in the U.S.
