Rooftop tests at MIT confirmed that the device works in real-world conditions. The prototype, under conditions of 20-30 percent humidity, was able to pull 2.8 liters (3 quarts) of water from the air over a 12-hour period, using one kilogram (2.2 pounds) of MOF. Your electric dehumidifier at home ‘produces’ very expensive water.” “There is no other way to do that right now, except by using extra energy. “This is a major breakthrough in the long-standing challenge of harvesting water from the air at low humidity,” said Omar Yaghi, one of two senior authors of the paper, who holds the James and Neeltje Tretter chair in chemistry at UC Berkeley and is a faculty scientist at Lawrence Berkeley National Laboratory. The solar-powered harvester, reported in the journal Science, was constructed at the Massachusetts Institute of Technology using a special material - a metal-organic framework, or MOF - produced at the University of California, Berkeley. A MOF he synthesized was used by MIT engineers to construct a water harvester that sucks water from dry air and condenses it for drinking.Ĭredit: Video by Roxanne Makasdjian and Stephen McNally, UC Berkeley. The Salineville water bottles will remain off shelves “until further notice while we continue to evaluate ongoing testing and potential impacts to the spring source,” Donovan said.Omar Yaghi explains how to make a MOF and their tremendous ability to absorb gases and liquids, including water directly from low-humidity air. “As we continue to receive these assurances from our Salineville water vendor, we also recognize that regional and national health officials continue to send resources to East Palestine to learn as much as possible about the potential impact to the health of the community,” he added. The water used in the products comes from “a protected spring located at a higher elevation than East Palestine and is not near groundwater sources directly impacted by the incident.”Ī third-party lab has been testing Salineville’s raw water sources and finished products and “has not found any evidence” that the water was negatively impacted by the derailment, Donovan said. Phosgene and hydrogen chloride, chemicals associated with a number of health risks, were released into the air during the fire.Īccording to Donovan, Giant Eagle has been in daily contact with representatives from the facility. The crash caused a fire before Norfolk Southern’s emergency team conducted a controlled burn of five tanks of vinyl chloride to avoid an explosion. The Salineville facility is about 25 miles southwest of East Palestine, where a Norfolk Southern train carrying hazardous chemicals derailed Feb. The products are sold in Giant Eagle, Market District and GetGo stores. The only varieties of Giant Eagle spring water produced there are in gallon size and larger containers. Spokesperson Dan Donovan said the company was operating “out of an abundance of caution” in its decision to remove all Giant Eagle brand spring water products sourced from the facility, located in Salineville, Ohio. Grocery chain Giant Eagle has temporarily stopped selling bottled water produced at a plant near East Palestine, Ohio, in light of concerns about the recent Norfolk Southern train derailment.
