This textbook provides a comprehensive review of the problems associated with the supply of drinking water in the developed world. Since the first edition of this book was published, water companies and regulators have been presented with numerous new challenges - global warming has seriously affected water supplies and water quality; advances in chemical and microbial analysis have revealed many new contaminants in water that were previously undetectable; and recent terrorist attacks have demonstrated how vulnerable water supplies are to contamination or disruption.
This new edition includes an overview of the current and emerging problems, with potential solutions. It has been completely updated, and includes the WHO Revised Drinking Water Guidelines. An ideal textbook for courses in environmental science, hydrology, environmental health and environmental engineering; it also provides an authoritative reference for practitioners and professionals in the water supply industry.
