“UV treatment utilizing LEDs would be more cost-effective, energy efficient and longer lasting,” says Dr. Ramón Collazo, an assistant professor of materials science and engineering at NC State and lead author of a paper describing the research. “Our work would also allow for the development of robust and portable water-treatment technologies for use in developing countries.”
As people pump groundwater for irrigation, drinking water, and industrial uses, the water doesn’t just seep back into the ground — it also evaporates into the atmosphere, or runs off into rivers and canals, eventually emptying into the world’s oceans. This water adds up, and a new study calculates that by 2050, groundwater pumping will cause a global sea level rise of about 0.8 millimeters per year.
Nearly 80 percent of disease in developing countries is linked to bad water and sanitation. Now a scientist at Michigan Technological University has developed a simple, cheap way to make water safe to drink, even if it’s muddy.
Climate change has been studied extensively, but a new body of research guided by a San Francisco State University hydrologist looks beneath the surface of the phenomenon and finds that climate change will put particular strain on one of our most important natural resources: groundwater.
Americans have clean and safe drinking water because water-supply companies rigorously treat it to adhere to U.S. Environmental Protection Agency (EPA) regulations. While chlorine has long been used as a disinfectant in drinking water, more and more U.S. water supply companies have been switching to chloramine. In fact, the EPA estimates that more than one in five Americans use drinking water that contains chloramine.
We take it for granted; whether it is the fresh drinking water that we drink or even flush the toilet with or a beautiful sunset over an unspoiled lagoon in the Maldives that we enjoy.
