Disinfectant selection is central to the design and operation of drinking water, wastewater, and reuse systems. Selecting Disinfectants in a Security-Conscious Environment provides a systematic method for evaluating disinfectants to meet your requirements. With this book, you can compare disinfection options consistently, taking into account operational issues, process and supply-chain reliability, environmental issues, and security considerations. The guide will help you evaluate disinfectants that meet your utility's needs from both a water-quality and a security perspective. The book provides tables that let you compare various disinfectants side-by-side. The tables list the advantages, disadvantages, typical uses, effectiveness, regulations, relative costs, safety and security considerations, and other relevant parameters, for free chlorine (gas, sodium or calcium hypochlorite, on-site generated hypochlorite) chloramines ultraviolet light ozone chlorine dioxideSafety and security have become key considerations for water and wastewater utilities in choosing disinfectants. In some cases, the cost of safety and security provisions can significantly affect the feasibility of disinfection options. Selecting Disinfectants in a Security-Conscious Environment provides a scientific methodology to expertly analyze and quantify safety and security risks and costs for any type of disinfectant. The information presented is consistent with the US Environmental Protection Agency's water utility security guidelines and the Department of Homeland Security Chemical Facility Antiterrorism Standards.

Drinking water utilities in the United States and around the world are facing significant challenges, such as serious water shortages, worn-out pipelines, population growth, and pollution of rivers, lakes, and groundwater. At the same time, the world water market presents important business opportunities, especially in countries with expanding economies, such as China, India, and Indonesia.Get inside the burgeoning worldwide water business with The Business of Water, a compilation of articles from Journal AWWA that explore from a business perspective the myriad important issues facing the water industry now and in the future. The articles were selected by water industry strategist Steve Maxwell, a consultant specializing in merger and acquisition advisory services and strategic planning for the water and broader environmental industries.Articles are organized in three primary areas:* The Global Water Problem: How Bad Is It?* The Water Industry: How Big Is It?* The Water Industry: Key Drivers and Trends

The most important resources at any utility are human resources. People make all the difference in the success or failure of your utility's operation. Managing utility workforce issues is the focus of this practical handbook for water utility human resources managers.The Water Workforce: Recruiting & Retaining High-Performance Employees examines the special human resource challenges facing utilities and offers tested strategies to address them. It will help you recruit, train, motivate, and retain high-quality employees-and build a stable and productive workforce that will meet the short- and long-term needs of your utility. The book focuses on the specific technical work needs of utilities and how to successfully apply workforce management principles in a water utility environment.The book discusses workforce planning methodology, recruiting, and retention, and presents a comprehensive approach to workforce improvement and organizational capacity building. It outlines four workforce development processes:* Defining the organization's work processes* Recruiting* Capacity building* Retention and succession planningUtilities can implement effective solutions to workforce problems with a planned approach to organization and work design, followed by action to improve the capacity of individual employees and their units, and ultimately, the whole organization. Although all utilities face workforce management issues, there are considerable differences between large and small utilities. This book addresses the needs of both with strategies to apply workforce management principles in even the smallest utility.Contents1. Workforce Challenges and Strategies for Success2.

Hazardous waste is a waste with properties that make it dangerous or potentially harmful to human health or the environment. Hazardous waste generally exhibits one or more of these characteristics: ignitability, corrosivity, reactivity or toxicity. The universe of hazardous wastes is large and diverse. Hazardous wastes can be liquids, solids, contained gases, or sludges. They can be the by-products of manufacturing processes or simply discarded commercial products, like cleaning fluids or pesticides. One major type is radioactive waste. This book brings together the latest research in this diverse field.

The papers in this volume arose out of two workshops entitled "Confinement and Remediation of Environmental Hazards," and "Resource Recovery," as part of the IMA 1999-2000 program year. These workshops brought together mathematicians, engineers and scientists to summarize recent theoretical, computational, and experimental advances in the theory of phenomena in porous media. The first workshop focused on the mathematical problems which arise in groundwater transport of contamination, and the spreading, confinement and remediation of biological, chemical and radioactive waste. In the second conference, the processes underlying petroleum recovery and the geological time scale of deformation, flow and reaction in porous media were discussed. Simulation techniques were used to simulate complex domains with widely-ranging spatial resolution and types of physics. Probability funcional methods for determining the most probable state of the subsurface and related uncertainty were discussed. Practical examples included breakout from chemical and radioactive waste repositories, confinement by injection of pore plugging material and bioremediation of petroleum and other wastes. This volume will be of interest to subsurface science practitioners who would like a view of recent mathematical and experimental efforts to examine subsurface science phenomena related to resource recovery and remediation issues.

On October 11, 2000, a breakthrough of Martin County Coal Corporation's coal waste impoundment released 250 million gallons of slurry in near Inez, Kentucky. The 72-acre surface impoundment for coal processing waste materials broke through into a nearby underground coal mine. Although the spill caused no loss of human life, environmental damage was significant, and local water supplies were disrupted. This incident prompted Congress to request the National Research Council to examine ways to reduce the potential for similar accidents in the future. This book covers the engineering practices and standards for coal waste impoundments and ways to evaluate, improve, and monitor them; the accuracy of mine maps and ways to improve surveying and mapping of mines; and alternative technologies for coal slurry disposal and utilization. The book contains advice for multiple audiences, including the Mine Safety and Health Administration, the Office of Surface Mining, and other federal agencies; state and local policymakers and regulators; the coal industry and its consultants; and scientists and engineers.
