(Science News) – America is built on lead. Networks of aging pipes made from the bluish-gray metal bring water into millions of U.S. homes. But when lead, a poison to the nervous system, gets into drinking water — as happened in Flint, Michigan — the heavy metal can cause irreparable harm (SN: 3/19/16, p. 8). In The Poisoned City, journalist Anna Clark provides a thorough, nuanced account of the public health disaster in Flint — one that, she argues, was magnified by government malfeasance and decades of systemic racism.Trouble first began in April 2014. To save the cash-strapped city some money, Flint’s emergency manager switched the city’s source of water from Detroit’s water system, which drew from Lake Huron, to one that tapped the Flint River. But the city’s water treatment program didn’t include corrosion control, which the Michigan Department of Environmental Quality said wasn’t necessary — a violation of federal law. The result: Corroded pipes leached lead into drinking water.Residents, forced to use the brown, smelly tap water, developed rashes and lost clumps of hair. Twelve people died from Legionella bacteria, which the corrosive water dislodged from pipes, and dozens more were sickened. Despite residents’ complaints, as well as an independent analysis that found higher-than-allowable lead levels, state officials insisted that the water was safe, even when their own internal records showed it was not. “Anyone who is concerned about lead in the drinking water in Flint can relax,” said one spokesperson for the Michigan Department of Environmental Quality.That’s when one of the book’s heroes, pediatrician Mona Hanna-Attisha, enters Clark’s story. About 18 months after Flint switched to its new water source, the percentage of children under age 5 with high blood-lead levels nearly doubled from 2.1 to 4 percent, Hanna-Attisha discovered after taking a close look at Flint kids’ medical records. (Hanna-Attisha’s own account of her experiences, What the Eyes Don’t See, was published in June.)Faced with mounting evidence that became hard to ignore, Gov. Rick Snyder negotiated a switch back to Detroit’s water system in October 2015, declaring a state of emergency a few months later. Meanwhile, taps in Flint were retrofitted with filters as the long, slow process of replacing pipes began. The Michigan National Guard trucked in bottled water.Readers who followed this crisis as it unfolded will still learn plenty in The Poisoned City. [more]
