The Edwards Aquifer in south-central Texas is the primary source of water for one of the fastest growing cities in the United States, San Antonio, and it also supplies irrigation water to thousands of farmers and livestock operators. It is also the source water for several springs and rivers, including the two largest freshwater springs in Texas that form the San Marcos and Comal Rivers. The unique habitat afforded by these spring-fed rivers has led to the development of species that are found in no other locations on Earth. Due to the potential for variations in spring flow caused by both human and natural causes, these species are continuously at risk and have been recognized as endangered under the federal Endangered Species Act (ESA). In an effort to manage the river systems and the aquifer that controls them, the Edwards Aquifer Authority (EAA) and stakeholders have developed a Habitat Conservation Plan (HCP). The HCP seeks to effectively manage the river-aquifer system to ensure the viability of the ESA-listed species in the face of drought, population growth, and other threats to the aquifer. This report is the third and final product of a three-phase study to provide advice to the EAA on various aspects of the HCP that will ultimately lead to improved management of the Edwards Aquifer. This final report focuses on the biological goals and objectives found in the HCP for each of the listed species.

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.

Because water in the United State has not been traded in markets, there is no meaningful estimate of what it would cost if it were traded. But failing to establish ground water's valueâ€"for in situ uses such as sustaining wetlands as well as for extractive uses such as agricultureâ€"will lead to continued overuse and degradation of the nation's aquifers. In Valuing Ground Water an interdisciplinary committee integrates the latest economic, legal, and physical knowledge about ground water and methods for valuing this resource, making it comprehensible to decision-makers involved in Superfund cleanup efforts, local wellhead protection programs, water allocation, and other water-related management issues. Using the concept of total economic value, this volume provides a framework for calculating the economic value of ground water and evaluating tradeoffs between competing uses of it. Included are seven case studies where ground-water valuation has been or could be used in decisionmaking. The committee examines trends in ground-water management, factors that contribute to its value, and issues surrounding ground-water allocation and legal rights to its use. The book discusses economic valuation of natural resources and reviews several valuation methods. Presenting conclusions, recommendations, and research priorities, Valuing Ground Water will be of interest to those concerned about ground-water issues: policymakers, regulators, economists, attorneys, researchers, resource managers, and environmental advocates.

"One of the world's great karstic aquifer systems, the Edwards aquifer system supplies water for more than 2 million people and for agricultural, municipal, industrial, and recreational uses. This volume reviews the current state of knowledge, current and emerging challenges to wise use of the aquifer system, and some technologies that must be adopted to address these challenges"--
