In the News: Ashok Gadgil & team reduces lead leaching rates in water pipes
Professor Ashok Gadgil and his research team have devised a novel way to protect the millions of people who at risk from water pipes that leach lead.
The team found that when a low voltage power source, about 1V, is connected to a lead pipe filled with a harmless phosphate solution and to a conductive wire within the pipe, an insoluble lead phosphate layer rapidly forms on the inside surfaces of the pipe.
