Understanding the issues that have been encountered at other sites, and the steps that have led to successful resolution of these issues, can provide great help to those considering, planning, or implementing new groundwater recharge projects. Recent technical advances and operational experience have demonstrated that well recharge is a feasible and cost effective method of artificially recharging natural aquifers. This practical guide reviews the technical constraints and issues that have been addressed and resolved through research and experience at many sites. The book presents aquifer storage recovery (ASR) technology and traces its evolution over the past 25 years in the United States. Procedures for groundwater recharge are presented, and selected case studies are examined. Drinking water quality standards and conversion factors are provided in the appendix for easy reference.

The definitive work on the subject, it offers you comprehensive and accurate coverage of the theory and techniques of ground water development. Provides not only a general overview of the topic with applications but also incorporates sufficient detail to be of use to professionals involved in any phase of ground water. Divided into three parts, the text traces the progression of the study of ground water from its origin through its development and exploitation. Part one deals mainly with the nature of ground water and where it can be found. Part two considers the parameters related to water well design and construction. In part three, there is a thorough review of well and well field operation, including monitoring for environmental protection. Although the focus is on high-capacity ground water producing installations, most of the material is also applicable to lower-yield wells.

"This study attempts to re-frame the current thinking on groundwater development and the implications for food security. Groundwater is an important source for irrigated agriculture as it generally furnishes reliable and flexible inputs of water. To this extent, groundwater is instrumental in managing risk and optimizing food production. However, this reliance upon shallow aquifer systems for irrigation has turned to dependency. Competition for groundwater is intense both between neighbouring users and among economic sectors. This study highlights the role of adaptive strategies in dealing with aquifer management and indicates directions of research and management."--Preface.

Groundwater serves many purposes. It is a source of public and private drinking water, it is utilized as an industrial feedstock and it is used in agriculture for irrigation and cattle watering. The abstraction of groundwater also serves many civil engineering purposes such as structures, construction pit dewatering and remediation of polluted groundwater. Furthermore, groundwater is increasingly used for supply and storage of energy for the cooling and heating of buildings. Many wells abstracting groundwater suffer from impaired performance as a result of clogging by mechanical or biogeochemical processes. This represents a significant economic loss due to volume reductions, cost of well rehabilitations or construction of new wells. Cause and Prevention of Clogging of Wells Abstracting Groundwater from Unconsolidated Aquifers provides a comprehensive description of the various causes and processes associated with well clogging in addition to describing methodologies for diagnosis and prevention.

In situ treatments involving the arrangement of contact between prospective reactants in complex porous media require a refined understanding of solute migration. However, the tools and methods used to predict and control fluid movement in the subsurface need significant improvement. Practitioners and regulators must develop novel methods to achieve an advanced understanding of treatment mechanisms. Remediation Hydraulics addresses the need to predict and control fluid movement in the subsurface. It demonstrates how to conduct realistic assessments of contaminant plume structure and achieve contact between injected reagents and target compounds. The book describes both the advection-dispersion and continuous random walk theories of mass transport as well as explains the practical implications of each theory in remedial system design. In addition, it devotes an entire section to the development of conceptual site models and hydrostratigraphic characterization techniques that will aid practitioners in assessing the role of depositional environments in patterning groundwater flows and containment distributions. Based the authors’ sound experience at over one hundred groundwater treatment projects, this bookprovides an arsenal of relevant theories and practical applications to aid practitioners and regulators in the prediction of fluid movement in the subsurface as well as in the design of pilot to full-scale remediation systems.

This study evaluates these two newly developed USEPA coliphage methods, which are under consideration for approval as required by the Groundwater Rule (GWR). Method 1601 is a qualitative two-step presence-absence procedure and Method 1602 is a quantitative single agar layer (SAL) procedure. This evaluation reports on their assessment of these methods for testing the vulnerability of groundwater for viral/fecal contamination as used for routine monitoring.
