William M. Alley
Groundwater is a hidden resource, difficult to study and also difficult to
explain to a lay audience. As a result, groundwater remains neglected in the
popular literature. No one has ever watched a sunset or gone fishing on
a body of groundwater, former Secretary of the Interior Bruce Babbitt
reminds us on the back cover of the book. Moreover, although many people know
the expression by Ben Franklin that, When the wells dry, we know
the worth of water, relatively few people know that groundwater pumping
also affects streams, lakes, wetlands and springs; these issues receive very
little press. Robert Glennons book, Water Follies, sets to turn
this situation around.
The book begins with the search of the bottled water industry for new sources of water, a search that we learn is not without controversy. After dipping into a discussion of water law and the history and uses of groundwater, Glennon takes us on a travelogue of a dozen stories that serve as case studies of the relationship between groundwater pumping and surface-water resources. We read about retirement homes built on depleted lakes in Florida, concerns about the drying up of sacred springs in Arizona, the effects of urban sprawl on river flow in Massachusetts, groundwater as the source of the famous River Walk in San Antonio and the challenges of providing water to tourists at the Grand Canyon. The stories provide a glimpse of modern-day water wars in places like the Upper San Pedro River basin in Arizona and the Apalachicola-Chattahoochee-Flint River basin in the southeastern United States.
Throughout the book, the author reminds us of the human capacity to ignore reality, in this case the reality that pumping groundwater has consequences. But he also acknowledges that the realities of groundwater can be difficult to see. For example, Glennon notes, it takes a rather sophisticated understanding to grasp how pumping municipal wells 10 miles from the San Pedro River is intercepting water that otherwise would reach the river.
Glennon dug deep into the background of many of his stories to bring us colorful personalities and quotes accompanied, at times, by wry commentary. Each chapter includes a map to orient the reader, and a substantial bibliography ends the book. A glossary helps the lay reader recall some of the key terms.
The book covers a lot of ground. At the same time, given the topic, and given that Glennon is a professor of law and public policy at the University of Arizona, I would like to have read more about the legal issues of conjunctive use of groundwater and surface water.
The books title reflects a tendency to dramatize the issues. For example, Glennon makes periodic references to environmental catastrophes and disastrous effects, and emphatically states the country cannot sustain even the current levels of groundwater use, never mind the projected increase. This statement is certainly true in some areas, but not in many others.
Lacking a specialization in hydrology, Glennon generally does a good job at presenting hydrologic concepts, with some exceptions in the detailed descriptions. For example, I found that the Humboldt River case study too readily dismissed geologic complexities and referred erroneously to a water table some 1,500 feet below the river bottom. Although such depths from the land surface to the water table might exist at the higher locations of the mine dewatering, the depth to the water table at the river would be much shallower.
In the final chapter, Glennon emphasizes that a complete misunderstanding of hydrology has been memorialized in many states, where groundwater and surface water are legally two unrelated things. He proposes eight avenues for reform of state laws and regulations. Included among these are simple conservation measures that are easy to administer and implement. Others are more draconian, such as imposing an extraction tax on water pumped from any well within a certain distance of a body of surface water. Some of his proposals, such as establishing minimum streamflows, are easier said than done, simply from a scientific point-of-view. Glennon also recommends collecting better information about the number of wells drilled in each state and how much water they pump, but does not address the importance of long-term monitoring of the resource. Nevertheless, it is to Glennons credit that he proposes solutions instead of just describing the problems.
Overall, this book makes for interesting reading, fills a gap in the environmental literature, and surely will draw attention to the long-term effects of groundwater pumping on our streams, lakes and wetlands. Despite the authors advocacy stance in many of the stories, the book serves to raise consciousness about a long-term environmental issue associated with the wise use of one of our most precious natural resources.
