The importance of high quality drinking water is vastly understated. Compromising approximately 75 percent of the body, water is found both inside and outside the cells and is the basis of all body fluids including blood, lymph, saliva, digestive juices, urine, and perspiration.
Therefore, an unadulterated source of pure drinking water and learning how to optimize hydration is one of the most fundamentally important things one can do for their health. Read more
Americans can take a warning from a University of Florida study of bottled water in China ─ don’t drink the liquid if you’ve left it somewhere warm for a long time.
Plastic water bottles are made from polyethylene terephthalate. When heated, the material releases the chemicals antimony and bisphenol A, commonly called BPA.
While the U.S. Food and Drug Administration has said BPA is not a major concern at low levels found in beverage containers, it continues to study the chemical’s impacts. Some health officials, including those at the Mayo Clinic, say the chemical can cause negative effects on children’s health. Read more
Researchers from North Carolina State University have developed a new technique that uses existing technology to allow researchers and natural resource managers to collect significantly more information on water quality to better inform policy decisions.
Researchers developed a new technique for collecting more (and more accurate) water quality data. The technique was tested in this brackish marsh.
“Right now, incomplete or infrequent water quality data can give people an inaccurate picture of what’s happening — and making decisions based on inaccurate data can be risky,” says Dr. François Birgand, an assistant professor of biological and agricultural engineering at NC State and co-author of a paper describing the work. “Our approach will help people get more detailed data more often, giving them the whole story and allowing them to make informed decisions.” Read more
Our ancient ancestors’ ability to move around and find new sources of groundwater during extremely dry periods in Africa millions of years ago may have been key to their survival and the evolution of the human species, a new study shows.
Insert shows with arrow the location of study area in eastern Africa. Map of the Northern Tanzanian Divergence Zone depicts the East African Rift System (EARS), containing Lake Natron (north), diverging around the Ngorongoro Volcanic Highland massif and splitting into two separate rift valleys (Lake Eyasi on west) and Lake Manyara (on east). Prevailing wind is from the east. Olduvai basin lies to the west of and in the rain shadow of Ngorongoro.
The research — published in the journal PLOS ONE — combines geological evidence from the Olduvai sedimentary basin in Northern Tanzania, which formed about 2.2 million years ago, and results from a hydrological model.
It shows that while water in rivers and lakes would have disappeared as the climate changed due to variations in Earth’s orbit, freshwater springs fed by groundwater could have stayed active for up to 1000 years without rainfall. Read more
Can technology help ease the U.S. water crisis?
Some utilities and private well owners hope so, as about 40% of the continental U.S. battles some form of drought and demand for water continues to grow. Worries about water shortages are heating up in various areas across the nation, especially in California and other Western states, where a punishing drought has entered its third year.
In an effort to encourage conservation and manage water use more efficiently, utilities and consumers are turning to a variety of new technology tools, including software and mobile apps that let households know just how much water they are using and how that usage stacks up against the neighbors. There also are sensors that can determine when wells are running low, and leak-detection systems for homes that send alerts and shut off the water when problems are suspected. Read more
