Volume 1 outlines water supply infrastructure. The requirements for supplying water to a home, a city or a factory can be very different. Experts in these fields explain the nuances of the details involved in maintaining adequate quantity and quality for these different consumers. Waste water management can be of even greater concern, yet its management can follow similar paths when compared to sophisticated water supply treatment. Both the physics and chemistry of these fields are fully covered. Volume 2 deals with the big picture of regional water supplies, how they become contaminated, how they can be protected and how they can best serve the surrounding populations and industries. Significant focus is placed upon the natural chemistry of available water supplies and its biological impacts. Case studies from regions around the world offer an excellent picture of the world's water resources.
