Clean Water is a book for anyone concerned about this precious resource who wants to become better informed. In straightforward language, Kenneth Vigil provides a comprehensive introduction to the many scientific, regulatory, cultural, and geographic issues associated with water quality and water pollution control.

Most other books on water quality and pollution control are highly technical and very specific, and are aimed at engineers, scientists, or attorneys. Clean Water, on the other hand, is a comprehensive discussion of the subject intended for a wider audience of science students, educators, and the general public.

Vigil avoids the use of technical jargon and uses many photos and diagrams to illustrate and explain concepts. He provides sufficient detail to educate readers about many broad topics and includes additional references at the end of each chapter for exploring specific topics in more detail.

Clean Water summarizes the basic fundamentals of water chemistry and microbiology and outlines important water quality rules and regulations, all in concise, understandable prose. It describes the basic scientific principles behind water pollution control and the broader approach of addressing water pollution problems through watershed management. There are sections on drinking water and on citizen involvement in water pollution control efforts at home and in the community.

This collection of essays by Thomas Kazen focuses on issues of purity and purification in early Judaism and the Jesus tradition. During the late Second Temple period, Jewish purity practices became more prominent than before and underwent substantial developments. These essays advance the ongoing conversation and debate about a number of key issues in the field, such as the relationship between ritual and morality, the role and function of metaphor, and the use of evolutionary and embodied perspectives. Kazen's research stands in constant dialogue with the major currents and main figures in purity research, including both historical (origin, development, practice) and cognitive (evolutionary, emotional, conceptual) approaches.

In 2000, a transformative climate-driven “megadrought” swept over the Colorado River watershed. By the early 2020s, levels on the river’s two largest reservoirs were hitting record lows and threatening the water supply for forty million people. Outside the West, water stocks are stressed even in states with bountiful rainfall such as Florida. From coast to coast, conventional measures to sustain the most fundamental natural resource on earth—drinking water—are coming up short. Recycled water could help close that gap.

In Purified: How Recycled Sewage Is Transforming Our Water, veteran journalist Peter Annin shows that wastewater has become a surprising weapon in America’s war against water scarcity. Annin probes deep into the water reuse movement in five water-strapped states—California, Texas, Virginia, Nevada, and Florida. He drinks beer made from purified sewage, visits communities where purified sewage came to the rescue, and examines how one of the nation’s largest wastewater plants hopes to recycle one hundred percent of its wastewater by 2035. At each stop, readers come face to face with the people who are struggling for, and against, recycled water. While the current filtration technology transforms sewage into something akin to distilled water—free of chemicals and safe to drink—water recycling’s challenge isn’t technology. It’s terminology. Concerns about communities being used as “guinea pigs,” sensationalist media coverage, and taglines like “toilet to tap” have repeatedly crippled water recycling efforts. Potable water recycling has become the hottest frontier in the race for expanded water supply options. But can public opinion turn in time to avoid the worst consequences?

Purified’s fast-paced narrative cuts through the fearmongering and misinformation to make the case that recycled water is direly needed in the climate-change era. Water cannot be taken for granted anymore—and that includes sewage.
 

Flowing through the heart of the North China Plain—home to 200 million people—the Yellow River sustains one of China’s core regions. Yet this vital water supply has become highly vulnerable in recent decades, with potentially serious repercussions for China’s economic, social, and political stability. The Yellow River is an investigative expedition to the source of China’s contemporary water crisis, mapping the confluence of forces that have shaped the predicament that the world’s most populous nation now faces in managing its water reserves.

Chinese governments have long struggled to maintain ecological stability along the Yellow River, undertaking ambitious programs of canal and dike construction to mitigate the effects of recurrent droughts and floods. But particularly during the Maoist years the North China Plain was radically re-engineered to utilize every drop of water for irrigation and hydroelectric generation. As David A. Pietz shows, Maoist water management from 1949 to 1976 cast a long shadow over the reform period, beginning in 1978. Rapid urban growth, industrial expansion, and agricultural intensification over the past three decades of China’s economic boom have been realized on a water resource base that was acutely compromised, with effects that have been more difficult and costly to overcome with each passing decade. Chronicling this complex legacy, The Yellow River provides important insight into how water challenges will affect China’s course as a twenty-first-century global power.
