PITTSBURGH—Lead was detected in 80 percent of water systems in Allegheny County, Pennsylvania, which encompasses Pittsburgh, in 2019, according to a new two-year analysis.
While the federal limit for lead in drinking water is 15 parts per billion (ppb), experts—including those at the American Academy of Pediatrics, the U.S. Centers for Disease Control (CDC) and Prevention, and the U.S. Environmental Protection Agency (EPA)—have long warned that there is no safe level of lead in drinking water.
