Water 4.0

[Wilmot McCutchen]

David Sedlak's new book, Water 4.0, tells the history of water and waste treatment. Water 1.0 was the Roman system of aqueducts to supply dense populations and flush away their waste. Water 2.0 was disinfection of drinking water, and 3.0 was treatment of sewage. Emerging technologies, such as desalination, and concerns, such as disinfection byproducts and endocrine disruptors in wastewater effluent, are succinctly presented in this lucid little book. It's a great service to have compiled this vital knowledge, which is hard to find. The author is the Malozemoff Professor in the Department of Civil and Environmental Engineering at UC Berkeley.
