A Handbook For State Ground Water Managers

This new edition adds several new chapters and is thoroughly updated to include data on new topics such as hydraulic fracturing, CO2 sequestration, sustainable groundwater management, and more. Providing a complete treatment of the theory and practice of groundwater engineering, this new handbook also presents a current and detailed review of how to model the flow of water and the transport of contaminants both in the unsaturated and saturated zones, covers the protection of groundwater, and the remediation of contaminated groundwater.

Existing and impending water shortages argue for improving water quantity and quality management. Groundwater Optimization Handbook: Flow, Contaminant Transport, and Conjunctive Management helps you formulate and solve groundwater optimization problems to ensure sustainable supplies of adequate quality and quantity. It shows you how to more effecti

Manual M73, Groundwater Management, is the culmination of efforts by members of AWWA's Groundwater Resource Committee to identify and demonstrate the value of using computer modeling tools to help utilities better manage their groundwater resources in light of greater competition for water and dwindling supplies in many parts of the world. In North America, we see acute issues developing in the Plains states, Rocky Mountains, desert Southwest, and even along parts of the Eastern Seaboard. In many of these cases, deep and often confined aquifers are being tapped for irrigation and potable supplies, but there is little hope these aquifers can recover their supplies in our lifetime. That creates the potential for serious economic and social consequences later in the 21st century for communities whose wells may run dry and have no backup options. To this end, this manual includes a discussion on the sustainability of groundwater supplies; overdrafting; and the need for groundwater protection, planning, and evaluation efforts that have evolved in the past 10 years. While groundwater management was incorporated to a small degree in the 2014 version of M21, Groundwater, the committee felt the topic has developed considerably over the past 10 years and that a more detailed and focused manual for groundwater management was timely. M21 will now focus primarily on operations.

One of the greatest conundrums facing the arid western United States is the availability, use, and quality of groundwater. In large sections of the West, groundwater is the only dependable source of water for agricultural production and home consumption. Yet many of the aquifers are being depleted at a rate that will suck them dry within a century. Furthermore, dependence upon groundwater in many areas will only increase in the future. This dependence is already having serious consequences for small towns on the Great Plains. Faced with growing costs associated with deeper wells and the need for ever more advanced technology for extracting water, these towns find they lack the resources to maintain current agricultural practices. In this timely assessment of the West's groundwater resources, the authors provide a detailed overview of groundwater management in the Western states. The authors present for each state the various management strategies, laws, and political realities that have made groundwater appropriation such a volatile subject. They also suggest possible difficulties that states and regions might face under current groundwater policies. By examining separate cases and viewing the West as a whole, the authors are able to identify not only the most pressing problems but also the most appropriate management techniques for protecting water supplies for future use.
