The study found that two in three Americans (66 percent) believe their own community’s clean drinking water is at risk, while 59 percent say a major overhaul of U.S. water infrastructure is needed to avoid that possibility. City-dwellers are especially likely to fear their community’s clean drinking water is at risk (70 percent versus 63 percent in rural areas). There is almost universal agreement (96 percent) that if the United States does not proactively invest in the country’s water infrastructure system now, it will end up costing more in the long run.
