The little-known story of the systems that bring us our drinking water, how they were developed, the problems they are facing, and how they will be reinvented in the near future
A fresh look at the world’s water crises, and the existing and emerging solutions that can be used to solve them It is not your imagination: water crises are more frequent. Our twentieth-century systems for providing the water that grows food, sustains cities, and supports healthy ecosystems are failing to meet the demands of growing population and the challenges brought on by climate change. But the grim news reports—of empty reservoirs, withering crops, failing ecosystems—need not be cause for despair, argues award-winning author David Sedlak. Communities on the front lines of previous water crises have pioneered approaches that are ready to be applied elsewhere. Some have resolved s...
This study evaluated the available information on the use, occurrence and analysis of PhACs in US water sources. It selected PhACs that are likely to be present at detectable concentrations in municipal wastewater effluent and agricultural runoff then developed simple analytical methods for quantifying these PhACs. With this and the samples attained, preliminary assessment of the ability of wastewater treatment plants, engineered treatment wetlands and soil aquifer treatment systems to remove PhACs was determined and discussed. Since PhACs have been confirmed as present in drinking water sources, additional research is recommended.

There is a secret hidden in the gospels. It's a secret in the sense that it is something that cannot be learned from others. The gospels can only point to it until we get the point for ourselves. The stark and startling revelation is this: we exist and are held in being because God loves us. This means that when we try to understand ourselves, when we ask, "Who am I?" we must more accurately ask, "Whose am I?" I am, you are, we are, the outpouring of love. We are loved absolutely and unconditionally, or we would not exist. Spirituality is about letting this reality permeate every aspect of our being, psyche, understanding, and experience. The founder of the Redemptorists, Saint Alphonsus Lig...
New York Times and Los Angeles Times Bestseller! As every day brings urgent reports of growing water shortages around the world, there is no time to lose in the search for solutions. The U.S. government predicts that forty of our fifty states-and 60 percent of the earth's land surface-will soon face alarming gaps between available water and the growing demand for it. Without action, food prices will rise, economic growth will slow, and political instability is likely to follow. Let There Be Water illustrates how Israel can serve as a model for the United States and countries everywhere by showing how to blunt the worst of the coming water calamities. Even with 60 percent of its country made ...
"Water scarcity, urban population growth, and deteriorating infrastructure impact water security around the globe. As California wrestles with the most significant drought in its recorded history, struggling to secure reliable water supplies for the future, it faces all of these crises. The story of California water, its history and its future, includes cautions and solutions for any region seeking to manage water among the pressures of a dynamic society and environment. Written by leading policy makers, lawyers, economists, hydrologists, ecologists, engineers and planners, Sustainable Water reaches across disciplines, uncovering connections and intersections. The solutions and provocations put forward in this book integrate water management strategies to increase resilience in a changing world"--Provided by publisher.
A radical new approach to tackling the growing threat of water scarcity Water is essential to life, yet humankind's relationship with water is complex. For millennia, we have perceived it as abundant and easily accessible. But water shortages are fast becoming a persistent reality for all nations, rich and poor. With demand outstripping supply, a global water crisis is imminent. In this trenchant critique of current water policies and practices, Edward Barbier argues that our water crisis is as much a failure of water management as it is a result of scarcity. Outdated governance structures and institutions, combined with continual underpricing, have perpetuated the overuse and undervaluation of water and disincentivized much-needed technological innovation. As a result "water grabbing" is on the rise, and cooperation to resolve these disputes is increasingly fraught. Barbier draws on evidence from countries across the globe to show the scale of the problem, and outlines the policy and management solutions needed to avert this crisis.
New York City's municipal water supply system provides about 1 billion gallons of drinking water a day to over 8.5 million people in New York City and about 1 million people living in nearby Westchester, Putnam, Ulster, and Orange counties. The combined water supply system includes 19 reservoirs and three controlled lakes with a total storage capacity of approximately 580 billion gallons. The city's Watershed Protection Program is intended to maintain and enhance the high quality of these surface water sources. Review of the New York City Watershed Protection Program assesses the efficacy and future of New York City's watershed management activities. The report identifies program areas that may require future change or action, including continued efforts to address turbidity and responding to changes in reservoir water quality as a result of climate change.
