Are Groundwaters Endless?

Are Groundwaters Endless?

Ninety Keys to Understanding Groundwaters


T. Ruf, J. Margat

Edition 2014

Where does the spring water come from? Can a well be dug anywhere? What are the threats to groundwaters? To whom do they belong? What are the advantages of exploiting groundwaters rather than surface water? Are the state and availability of resources known? This book answers the potential questions about groundwaters (water tables and deep water tables). It provides an inventory of geological and technical knowledge and highlights the economic, ecological, regulatory, political and social issues of this fragile resource.
