Based on new primary and secondary drinking water standards, this detailed manual presents water treatment methods that are considered the "best available technology" by the U.S. Environmental Protection Agency (EPA). It examines the design of water supplies for membrane water treatment plants, including reverse osmosis, membrane filtration, and electrodialysis methods, and it explains process design and the water quality problems associated with each process. It also considers significant aspects of membrane process and groundwater and surface water supply development. Information necessary to operate water supplies and evaluate problems in the system are provided, in addition to specific well construction details necessary for the water wells used to supply membrane plants.
Learn how to handle the uncertainty associated with environmental liability in A Lender's Guide to Environmental Liability Management. This concise, nontechnical handbook provides detailed information on how these ever-present liabilities can be managed effectively. It gives you the facts you need to explore lending opportunities in new areas while ensuring that your institution operates without unnecessary exposure to financial loss. This much-needed guide provides down-to-earth explanations of the liabilities arising from environmental problems, the science behind these liabilities, and the methods that lenders should implement to minimize financial risk - all without a single mathematical or scientific equation. The guide, divided into six main sections, is filled with must-have information focusing on o environmental law and the lender o the science of soil and groundwater contamination o recommendations for lending institutions' environmental policies o methods for management of contamination liability o techniques for management of contaminated sites o and the lender's role in trusts and financial management. Become environmentally literate and improve your financial decision-making outcomes with A Lender's Guide to Environmental Liability Management. This extremely useful and practical book will save you worry, time, and money.
A large part of the global population lives in arid lands which have low rainfall and often lack the water required for sustainable population and economic growth. This book presents a comprehensive description of the hydrogeology and hydrologic processes at work in arid lands. It describes the techniques that can be used to assess and manage the water resources of these areas with an emphasis on groundwater resources, including recent advances in hydrologic evaluation and the differences between how aquifer systems behave in arid lands versus more humid areas. Water management techniques are described and summarized to show how a more comprehensive approach to water management is required in these areas, including the need to be aware of cultural sensitivities and conditions unique to many arid regions. The integration of existing resources with the addition of new water sources, such as desalination of brackish water and seawater, along with reusing treated wastewater, will be required to meet future water supply needs. Also, changing climatic conditions will force water management systems to be more robust so that future water supply demands can be met as droughts become more intense and rainfall events become more intense. A range of water management techniques are described and discussed in order to illustrate the methods for integrating these measures within the context of arid lands conditions.
