In Purified, 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, listeners 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.
