Michigan Attorney General Bill Schuette has announced he will investigate the water crisis in Flint to determine whether any Michigan laws have been violated. This comes as Governor Rick Snyder has appealed to President Obama to declare a major disaster over lead poisoning in Flint’s drinking water. The poisoning began after an unelected emergency manager appointed by Snyder switched the city’s water source to the corrosive Flint River in a bid to save money. Residents have reported lasting health impacts, including developmental and cognitive impairment in children. Governor Snyder asked for federal aid Thursday, amid new revelations that at least 10 Flint residents have died from Legionnaires’ disease during a surge in infections caused by the water-borne bacteria. This comes as the World Economic Forum’s annual Global Risks report has ranked water crises as the top global risk to industry and society over the next decade. We’ll go to Michigan to speak with Dr. Mona Hanna-Attisha, who headed the September study that discovered high levels of lead in the blood of Flint’s children, later in the broadcast.
