Expanding water reuse-the use of treated wastewater for beneficial purposes including irrigation, industrial uses, and drinking water augmentation-could significantly increase the nation's total available water resources. Water Reuse presents a portfolio of treatment options available to mitigate water quality issues in reclaimed water along with new analysis suggesting that the risk of exposure to certain microbial and chemical contaminants from drinking reclaimed water does not appear to be any higher than the risk experienced in at least some current drinking water treatment systems, and may be orders of magnitude lower. This report recommends adjustments to the federal regulatory framework that could enhance public health protection for both planned and unplanned (or de facto) reuse and increase public confidence in water reuse.

The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

While covering the fascinating history of wind power as a whole, this timely handbook focuses on current technological developments and the promise—and pitfalls—of wind energy as part of the world's energy future. The use of wind power for the generation of electricity holds vast potential for solving the world's energy problems, but numerous technical and social issues must be addressed before that potential can be realized. This handbook will both educate students about current issues related to wind energy and introduce the ways in which mankind has harnessed the wind through the ages. The book covers topics as diverse as early windmills in Europe, the United States, China, and the Middle East; the development of wind farms for electricity generation; and political factors involved in the development of wind energy today. Conventional wind turbine mechanics are explained, as are the technical improvements that drive modern wind turbines and other wind systems. What makes the handbook unique is that it combines hard science with perspective pieces that address topics such as potential environmental damage that can result from modern wind technology, and how recent developments in wind turbine technology hold the promise for considerably reducing the cost of this alternate energy source, making it competitive with conventional fossil fuels. Readers will be engaged by extensive discussion of the economic, political, and ethical issues raised by the expanding use of wind energy in the United States and elsewhere, and they will be intrigued by a look at what wind power can mean to the planet's energy future.
