A valuable resource for those of us that care about the environment, public health, and simple drinking water, worldwide. All of us are affected by the delicate balance between human use and groundwater realities. This book is a dense but relatively easy read. Some chapters present facts that are simply harrowing from a scientific standpoint, others, such as the chapter dealing with the San Pedro River and its relevance to migratory birds, profoundly disheartening.

I wish I could give this book to my legislators, to developers, to city managers. People need to listen, to heed the cautionary information Alley offers in this book.
