Book excerpt: The purpose of the project was to demonstrate the value of age-dating and isotopic tracers in characterizing the flow dynamics and water quality changes in a complex groundwater domain that includes high capacity municipal pumping wells, a geologic fault, and artificial recharge facilities with deep lake-like recharge ponds. Characterizing water quality changes during recharge and transport in groundwater was also an objective of this investigation. Below (west of) the Hayward Fault (BHF), water ages correlated well with aquifer layer sequence. BHF tracers did not reach the BHF wellfield within the time frame of the experiment. Above (east of) the fault, (AHF) tracers reached the targeted wellfield in only 60 days, indicating substantial heterogeneity and a fast travel time along preferential pathways compared to the average travel time of 2+ years indicated by age-dating and more classical estimating methods. A reconnaissance of water quality, conducted concurrently with the tracer studies, suggested certain water quality improvements occurring in either the pond sediment or the near-pond aquifer media. Variations in groundwater age depended on location and depth. A survey of natural isotopes indicated mixing of young and older water in wells, increasing age with depth of aquifer layer, and possible dissolution of carbonate minerals. AHF tracer experiments, along with other analysis, suggested that tracers probably percolated preferentially at shallow depths in the pond near the shoreline. Much of the tracer remained in deep pond water over time, increasing residence time in down-gradient wells. The tracer studies provided evidence of preferential pathways and heterogeneity in the AHF aquifer and a fast minimum travel time to the AHF wellfield. The tracer added to BHF ponds was detected in just two monitoring wells, but not at the BHF wellfield over the 10-month period. An AHF tracer from a small pond spanning the fault did, however, appear at the BHF wellfield. BHF pond water flows mainly to distal portions of the groundwater basin, or reaches the wellfield over a slow, circuitous route.

This book was released on 2020-01-17 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water of appropriate quantity and quality is essential for drinking, sanitation, and food, energy, and industrial production for any society and is derived for most needs from surface- or groundwater sources. Studies suggest that groundwater use in irrigation globally is increasing in total volume as well as a percentage of all water used for irrigation, with the demand for groundwater resources increasing as available primary surface water supplies are depleted. Particularly in arid regions, groundwater may be the most accessible water supply for any purpose, leaving groundwater withdrawals concentrated in areas that are already experiencing water stress. Even in the presence of direct ground observations and measurements of the water table, quantitative evaluation of groundwater storage, flow, or recharge at different scales requires remotely sensed data and observations applied to groundwater models. Resolving the interaction of groundwater storage, flow, and recharge at a scale at which basins are managed requires remotely sensed data and proxy data. In June 2019, the Water Science and Technology Board of the National Academies of Sciences, Engineering, and Medicine convened a workshop to identify scientific and technological research frontiers in monitoring and modeling groundwater recharge and flow in various regions of the world. The goals of the workshop were to assess regional freshwater budgets under major use scenarios, including agriculture, industry, and municipal; examine state of the art research frontiers in characterizing groundwater aquifers, including residence time, quantity, flow, depletion, and recharge, using remotely sensed observations and proxy data; discuss groundwater model uncertainties and methods for mitigating them using sparse ground observations or data and other approaches; and consider our ability to detect which water management strategies that affect groundwater flow and recharge are being used and any changes in their use over time. This publication summarizes workshop presentations and plenary discussions.

Book excerpt: Potential changes to climate and precipitation patterns from anthropogenic influences like global climate change could have an impact on Michigan’s groundwater resources. Indirectly this could have an effect on Michigan’s surface waters as well, since groundwater and surface waters are intimately linked to form one system. This investigation utilized stable isotopes of oxygen and hydrogen found in precipitation, groundwater and surface waters to better understand the contribution of different types of precipitation to recharge of a shallow aquifer in Manistee National Forest, MI. The study also examines the contribution of this shallow groundwater to streamflow in the nearby White River. When combined with various physical and chemical hydrologic approaches, the dynamics of precipitation, groundwater flow and groundwater discharge into the stream become clearer. Samples from the different waters were collected from February 2015 to January 2016. During sampling groundwater head, stream discharge and other parameters were measured. These data provide valuable insight that will help the U.S. Forest Service better manage this natural resource.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of techniques that are available to characterize sedimentary aquifers. Groundwater flow and solute transport are strongly affected by aquifer heterogeneity. Improved aquifer characterization can allow for a better conceptual understanding of aquifer systems, which can lead to more accurate groundwater models and successful water management solutions, such as contaminant remediation and managed aquifer recharge systems. This book has an applied perspective in that it considers the practicality of techniques for actual groundwater management and development projects in terms of costs, technical resources and expertise required, and investigation time. A discussion of the geological causes, types, and scales of aquifer heterogeneity is first provided. Aquifer characterization methods are then discussed, followed by chapters on data upscaling, groundwater modelling, and geostatistics. This book is a must for every practitioner, graduate student, or researcher dealing with aquifer characterization .

Book excerpt: As demand for water increases, water managers and planners will need to look widely for ways to improve water management and augment water supplies. This book concludes that artificial recharge can be one option in an integrated strategy to optimize total water resource management and that in some cases impaired-quality water can be used effectively as a source for artificial recharge of ground water aquifers. Source water quality characteristics, pretreatment and recharge technologies, transformations during transport through the soil and aquifer, public health issues, economic feasibility, and legal and institutional considerations are addressed. The book evaluates three main types of impaired quality water sourcesâ€"treated municipal wastewater, stormwater runoff, and irrigation return flowâ€"and describes which is the most consistent in terms of quality and quantity. Also included are descriptions of seven recharge projects.

Scientific findings underpin radiation risk evaluation and international protection standards. This report comprises a report with two underpinning scientific annexes. The first annex recapitulates and clarifies the philosophy of science as well as the scientific knowledge for attributing observed health effects in individuals and populations to radiation exposure, and distinguishes between that and inferring risk to individuals and populations from an exposure. The second annex reviews the latest thinking and approaches to quantifying the uncertainties in assessments of risk from radiation exposure, and illustrates these approaches with application to examples that are highly pertinent to radiation protection.

This book was released on 2022-03-07 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alpine aquifers play a critical role in the hydrology of mountainous areas by sustaining base flow in downstream rivers during dry periods and retarding flood propagation after heavy precipitation events. Progressing climate change alters climatic and meteorological boundary conditions as well as the hydraulic response of alpine catchments by ablating glaciers and thawing permafrost. Rock glaciers exert a controlling influence on the catchment response due to their prominent groundwater storage and complex drainage characteristics. This thesis investigates the hydrogeology and internal structure of the active rock glacier Innere Ölgrube (Ötztal Alps), which governs catchment runoff and is affected by permafrost degradation. A 3D geometrical model of its internal structure is obtained by combining geophysical data and permafrost creep modelling. Available data and new results are integrated into a conceptual hydrogeological model providing a sound basis for the implementation of a prospective numerical groundwater flow model. Hydraulic properties of the hydrostratigraphic units constituting the rock glacier are estimated and groundwater recharge fluxes quantified. Fundamental properties of the heterogeneous groundwater flow system within the rock glacier are discussed and compared to existing rock glacier studies.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Civilizations have typically obtained water from surface-water resources throughout most of human history. Only during the last 50-70 years has a significant quantity of water been obtained by pumping groundwater. During this short time, alarming levels of groundwater depletion have been observed worldwide, especially in semi-arid and arid regions that rely heavily on groundwater pumping from clastic sedimentary basins. In order to reverse the negative effects of over-exploitation of groundwater resources, we must transition from treating groundwater mainly as an extractive resource to one in which sustainable management is pursued more aggressively. Numerical groundwater models are valuable tools for characterizing groundwater systems, but are often hamstrung by limited data and/or poor process representation. Several case studies are presented to highlight both the value and the uncertainty of models for understanding water budgets and representing water-flow processes. Simulations of managed aquifer recharge (MAR) dynamics reveal the influence of alluvial geologic architecture on MAR potential and highlight the value of capturing detailed geologic heterogeneity and physical processes that are not typically included in groundwater models when evaluating MAR potential. Additionally, a comparison of two regional-scale agricultural groundwater models of the Central Valley shows how both conceptual differences can contribute to differences in water budget estimates when there is a lack of comprehensive groundwater pumping measurements. Finally, an opinion is presented which outlines how the combination of comprehensive water resources accounting and a functioning water market that includes a central clearinghouse for water transactions holds great promise for reducing magical thinking and dissolving many water resources management obstacles.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to document for the first time the dimensions and requirements of effective integrated groundwater management (IGM). Groundwater management is a formidable challenge, one that remains one of humanity’s foremost priorities. It has become a largely non-renewable resource that is overexploited in many parts of the world. In the 21st century, the issue moves from how to simply obtain the water we need to how we manage it sustainably for future generations, future economies, and future ecosystems. The focus then becomes one of understanding the drivers and current state of the groundwater resource, and restoring equilibrium to at-risk aquifers. Many interrelated dimensions, however, come to bear when trying to manage groundwater effectively. An integrated approach to groundwater necessarily involves many factors beyond the aquifer itself, such as surface water, water use, water quality, and ecohydrology. Moreover, the science by itself can only define the fundamental bounds of what is possible; effective IGM must also engage the wider community of stakeholders to develop and support policy and other socioeconomic tools needed to realize effective IGM. In order to demonstrate IGM, this book covers theory and principles, embracing: 1) an overview of the dimensions and requirements of groundwater management from an international perspective; 2) the scale of groundwater issues internationally and its links with other sectors, principally energy and climate change; 3) groundwater governance with regard to principles, instruments and institutions available for IGM; 4) biophysical constraints and the capacity and role of hydroecological and hydrogeological science including water quality concerns; and 5) necessary tools including models, data infrastructures, decision support systems and the management of uncertainty. Examples of effective, and failed, IGM are given. Throughout, the importance of the socioeconomic context that connects all effective IGM is emphasized. Taken as a whole, this work relates the many facets of effective IGM, from the catchment to global perspective.
