We all know that the earth and all upon it face a growing crisis. Global climate change is rapidly advancing, melting glaciers, eroding soil, causing freak and increasingly wild storms, and displacing untold millions from rural communities to live in desperate poverty in peri-urban slums. Almost every human victim lives in the global South, in communities not responsible for greenhouse gas emissions. The atmosphere has already warmed up almost a full degree in the last several decades and a new Canadian study reports that we may be on course to add another 6 degrees Celsius (10.8 degrees Fahrenheit) by 2100.

The study was carried out by Circle of Blue, a network of journalists and scientists dedicated to water sustainability, and could have implications not just for the relationship between energy demand and water scarcity in the U.S. but elsewhere in the world, as well. "It is not just that energy production could not occur without using vast amounts of water. It's also that it's occurring in the era of climate change, population growth and steadily increasing demand for energy," explained Circle of Blue's Keith Schneider, who presented the findings in Washington Wednesday.

The research, led by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo., suggests that the reduced flows in many cases are associated with climate change, and could potentially threaten future supplies of food and water. [...more]
Bottled water across the country contains a wide variety of toxic substances, according to laboratory tests conducted by the Environmental Working Group (EWG).
"Our tests strongly indicate that the purity of bottled water cannot be trusted," the study authors write. "Given the industry's refusal to make available data to support their claims of superiority, consumer confidence in the purity of bottled water is simply not justified."
It's no simple matter to figure out how regional changes in precipitation, expected to result from global climate change, may affect water supplies. Now, a new analysis led by MIT researchers has found that the changes in groundwater may actually be much greater than the precipitation changes themselves. [...more]
Ten popular U.S. bottled water brands contain mixtures of 38 different pollutants, including bacteria, fertilizer, Tylenol and industrial chemicals, some at levels no better than tap water, according to laboratory tests recently conducted by Environmental Working Group (EWG). [...more]
Choosing tap water over bottled water is better for consumers’ health, their pocketbooks, and the environment, according to a report by Food & Water Watch. The report was released on the heals of a San Francisco executive order banning the use of city funds for bottled water and a U.S. Conference of Mayors resolution to study problems with bottled water consumption.

Modern agriculture and land-use practices may lead to major disruptions of the world’s water flows, with potentially sudden and dire consequences for regions least able to cope with them researchers at the Stockholm University-affiliated Stockholm Resilience Centre and McGill University have warned. [...more]
Analysis of tap water supplies in major metropolitan areas conducted by the Associated Press has revealed that the water supply in 24 major U.S. cities -- serving over 40 million people -- are contaminated with trace amounts of pharmaceuticals including antibiotics, anti-seizure medications, anti-inflammatory drugs, psychotropic drugs, pain medications and even caffeine.

Some companies are bottling tap water, giving the impression it is purer water, and selling it at huge prices. The real issue then becomes the bottled water itself in terms of the energy required to produce, transport and dispose of the bottles. It is also an issue if the water in the bottle is the same, or similar to, tap water. [...more]
