How did branded bottles of water insinuate themselves into our daily lives? Why did water become an economic good -- no longer a common resource but a commercial product, in industry parlance a &quot,fast moving consumer good,&quot, or FMCG? Plastic Water examines the processes behind this transformation. It goes beyond the usual political and environmental critiques of bottled water to investigate its multiplicity, examining a bottle of water's simultaneous existence as, among other things, a product, personal health resource, object of boycotts, and part of accumulating waste matter. Throughout, the book focuses on the ontological dimensions of drinking bottled water -- the ways in which this habit enacts new relations and meanings that may interfere with other drinking water practices.The book considers the assemblage and emergence of a mass market for water, from the invention of the polyethylene terephthalate (PET) bottle in 1973 to the development of &quot,hydration science&quot, that accompanied the rise of jogging in the United States. It looks at what bottles do in the world, tracing drinking and disposal practices in three Asian cities with unreliable access to safe water: Bangkok, Chennai, and Hanoi. And it considers the possibility of ethical drinking, examining campaigns to &quot,say no&quot, to the bottle and promote the consumption of tap water in Canada, the United States, and Australia.
