"A good integral overview on the relevant topics related to water usage which are of importance to consider when large scale applications are considered."-- Michel Boesten, University of Groningen, Netherlands"This book ...brings to light the contemporary issues along with the traditional issues associated with the water sector."-- Suresh Renukappa, University of Wolverhampton, UK"I was impressed with Gray’s third edition, and the fourth appears to build on that success. I find it to be a good general overview of water systems and water pollution control and, in a time when students find it hard to buy one specialized book let alone several, this book is broad enough to meet several needs simultaneously."-- Charles V. Shorten, West Chester University, USA
