EPA AND CDC WARNING. "in 1994 and 1995, 45 million Americans drank water from water systems that fell short of SDWA standards. Adding gravity to the situation ... CDC and the EPA advised that people with weakened immune systems should consult with their doctors and consider boiling their drinking water to kill any cryptosporidium." http://www.nrdc.org/health/kids/ocar/chap7.asp View in LinkedIn

ESPECIAL DANGER FOR CHILDREN. Legal standards for drinking water were set based on adults. "An infant living solely on formula consumes about one-seventh of its own weight of water each day, which would correspond to approximately three gallons of water for a 155-pound adult man." http://www.nrdc.org/health/kids/ocar/chap7.asp View in LinkedIn

LEAD IN WATER. "In 1991, the EPA estimated that lead in drinking water harms the health of millions of children, causing more than 560,000 children to exceed the level of concern for blood-lead levels defined by the CDC. (A recent EPA rule regulating lead in drinking water may have reduced this number of children.). Particularly susceptible to waterborne lead poisoning are infants." http://www.nrdc.org/health/kids/ocar/chap7.asp View in LinkedIn

NRDC REPORT ON US WATER. "A 1994 study estimated that some 14.1 million Americans drank water contaminated with the pesticides atrazine, cyanazine, simazine, alachlor, and metolachlor. The manufacturers of these agricultural herbicides have shown that these chemicals may cause cancer, birth defects, and genetic mutations." http://www.nrdc.org/health/kids/ocar/chap7.asp View in LinkedIn

WATER QUALITY IS A KEY ISSUE. "William K. Reilly, Administrator of the EPA under the Bush Administration, classified drinking water contamination among the top four public health risks posed by environmental problems ... 560,000 people become moderately to severely ill each year from consuming contaminated water ... (And) About 10,700 bladder and rectal cancers each year." http://www.nrdc.org/health/kids/ocar/chap7.asp View in LinkedIn

SCATHING REVIEW OF US DRINKING WATER, BY NRDC. At almost every level, the report finds deficiencies that have made millions of Americans sick. The biggest public health tradeoff today is keeping serious water pathogens at bay, which cause dramatic publicized deaths, in exchange for increased carcinogen exposure, which takes decades to develop. A must-read. http://lnkd.in/de4yJfC View in LinkedIn

GRAPHENE FILTERS. "University of Manchester researchers have taken another key step toward a seawater filter: they’ve developed one-atom-wide graphene-oxide (GO) capillaries by building multilayer GO membranes (laminates). "Our ultimate goal is to make a filter device that allows a glass of drinkable water made from seawater after a few minutes of hand pumping.” http://lnkd.in/dGmdJee View in LinkedIn

DISTILLATION STILL DRIVES THE MIT TECHNOLOGY. “We have a gas stream that’s in a closed loop and that’s going around, picking up the water at one end in a humidifier and then condensing the water out at the other end in a de-humidifier, and we do it at a fairly low temperature so we don’t have to take the water to boiling point.” http://lnkd.in/dsrDsjX View in LinkedIn

MIT'S GRADIENT COMPANY "is now courting some of the giants in the U.S. gas and oil markets with one promise: they can purify contaminated water for less than it costs to dispose of it ... applications ranging from purification in African and Indian coastal slums, to decontamination of water produced in gas and oil wells. The technology is based on a low energy, carrier gas extraction system." http://lnkd.in/dsrDsjX View in LinkedIn

GRAPHENE FILTERS WITH TITANIUM. "The technology will never be strong enough to completely clean drinking water on its own. Rather, she sees it as a polishing step after traditional water treatment processes to mop up the most insidious pollutants." http://www.acs.org/content/acs/en/pressroom/newsreleases/2014/march/high-tech-materials-purify-water-with-sunlight.html View in LinkedIn
