The Environmental Protection Agency’s (EPA’s) recommendations for treating water after a natural disaster or other emergencies call for more chlorine bleach than is necessary to kill disease-causing pathogens and are often impractical to carry out, a new study has found. The authors of the report, which appears in the ACS journal Environmental Science & Technology, suggest that the agency review and revise its guidelines.
Daniele Lantagne, who was at the Centers for Disease Control and Prevention (CDC) at the time of the study and is now at Tufts University, and colleagues note that after natural disasters such as floods, clean water can be scarce. To prevent the spread of water-borne illnesses, the EPA currently recommends “bottle, boil, bleach” in case of a water emergency. That is, people should turn to bottled water as a first resort. If that’s not an option, then they should boil available water to disinfect it. Далее
The shale gas boom has transformed the energy landscape in the U.S., but in some drier locations, it could cause conflict among the energy industry, residents and agricultural interests over already-scarce water resources, say researchers. They add that degraded water quality is a potential risk unless there are adequate safeguards. The article appears in the ACS journal Environmental Science & Technology.
Meagan S. Mauter and colleagues point out that a major criticism of extracting shale gas through hydraulic fracturing, or “fracking,” is that it requires tremendous amounts of water — 2.5 to 5 million gallons — to develop a single well. Water, along with chemicals and sand, is injected under high pressure into wells to create cracks, or fractures, in shale and release stored gas. In some water-rich places, such as Pennsylvania, this is not a significant problem. Далее
I found these water conservation posters online a few years ago and have been holding onto them. Many cities and other organizations create marketing materials to educate people about water conservation. In this day and time, it is strange to think about getting people to conserve water for the good of their nation, particularly for a war effort.
It is hard to think about anyone rationing or conserving today for a war effort (even though we are presently at war). Today, pleas for water conservation are made for the environment’s sake, your personal footprint sake, or for money saving sake. Далее
Most of us have heard it a hundred times: drink eight glasses of water a day to stay healthy and hydrated. And while hydration is genuinely important for our health, if you’re guzzling all that water with your meals it can actually have a negative impact on your digestion.
It’s true that the entire digestive system works more efficiently when it’s well-hydrated, but this doesn’t mean it should be flooded with cold water right when it’s working to digest your last meal. Too much water during meals can interfere with natural levels of acid and bile needed in the stomach to properly digest your food. In particular, too much cold water during meals can slow digestion and may cause cramping in sensitive individuals. Далее
If you went up to the average person on the street today and tried to explain that most Americans drink, bathe in, and wash their dishes and clothes in an industrial waste product that is linked to causing endocrine disruption and cancer, you might be labeled a loon.
But this is exactly what millions of city-dwellers do every day without realizing it, thanks to an outdated and completely unscientific public health intervention known as artificial water fluoridation. Далее
