The single greatest reservoir of usable water for man lies underground. Its location, management, protection and remediation have been a central focus of hydrology for much of the past century. Experts throughout the world have covered this subject, in unimagined detail. Ground water remains unseen but no longer unknown, and now amazingly well defined in every aspect of quality and quantity, development, protection and remediation.

Maximizing the use of our visible surface supplies in light of their greatest need in agriculture presents an enormous challenge throughout the world. New techniques in agricultural applications to preserve resources and increase yields are featured. Dams, lakes, and hydraulic features of surface water systems are amply covered, along with the importance of storm water management to growing communities.

This volume 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.
