Description : No one has recorded when well digging started, but surely humans imitated elephants in digging holes in the sand to access cooler water that didn’t make the children sick. Eventually, humankind began to redesign, maintain, and repair the wells they constructed, but when wells became "commodities" in the twentieth century, this maintenance ethic was fogotten. Recapturing that ethic, Sustainable Wells: Maintenance, Problem Prevention, and Rehabilitation is a guide to keeping well systems operating at peak capacity. The book focuses on how to prevent and forestall problems, and manage the problems with wells as they age. Examining the many challenges that come with maintaining well performance, the book provides a comprehensive yet readable state-of-the-art summary of performance maintenance, problem prevention, and rehabilitation or restoration practice with the goal of sustaining optimal performance over the long run. Rather than focusing on a certain aspect of well cleaning, or a particular technical approach, it covers the scope of maintenance and rehabilitation, from planning to evaluation testing. It also addresses the crucial subjects of preventive design, maintenance monitoring from electrical to biofouling, and evaluation testing. An exploration of the subject without a vendor or strong regional bias, the book is based on the authors’ extensive hands-on experience serving well-operating clientele. In addition to water supply wells, it addresses the problems and maintenance issues of monitoring, plume control, and other "environmental" wells. Compiling information from existing literature into a single source, and combining that information with experience, the book provides recommendations based on historical performance. Copiously illustrated with approximately ninety black and white photographs, figures, and a color insert, the book reflects the changes in the profession that have occurred during the past decade or so. These features and more make this the first resource to turn to when devising solutions for maintaining and improving well performance.

Description : Water is a prime natural resource and a basic necessity for sustaining life on earth. Supplying adequate amount of potable water to the global population is a gigantic task in the wake of growing industrial and domestic needs. The threat of climate change and global warming which has aggravated the problem of water shortage is of particular concern to India as we are largely dependent on glaciers and rainfall for water supply. The United Nations World Water Development Report, Water: A Shared Responsibility emphasizes the need for good governance to meet the ever-increasing demand for water. The report asserts that mismanagement, corruption, lack of appropriate institutions, bureaucratic inertia and paucity of investment in human and physical sources mar water management today. The situation calls for right policy decisions and adoption of sustainable practices. The problem is acute in India because of its high population density, space and time variability of rainfall and increasing depletion and contamination of its surface and groundwater resources. Most water resources in India are contaminated by sewage and agricultural run-off. Besides, overuse of pesticides and chemicals in agriculture is the primary cause of groundwater pollution in India. Further, uneven water distribution across the country is another aspect of water problem. A large area of the country is water deficit whereas a small part is bestowed with abundance of water. This has led to inter-state conflicts. The present anthology contains well researched articles by eminent scholars who have deeply analysed the problem and its various implications. Major factors responsible for the problem have been studied in detail and some measures have been suggested to retrieve the situation. The book will serve as a reference source for students, researchers and policymakers and all those concerned with an ensured supply of water across the country.
