Why lead pipes in Chicago have the nation’s experts worried

Jean Cochrane

Wearing glasses and a heavy green sweater, Patrick MacRoy kneels down in the sweltering basement of his yellow brick Andersonville condominium and presses a key against the metal pipe. As he begins scratching it, silver filings shave off the pipe and fall onto the floor. That’s how MacRoy, the former director of the city’s Lead Poison Prevention Program, knows that the pipe (known as a service line) that brings drinking water from the city’s water main into his twenty-four-unit building is made out of lead, a toxic metal long known to cause cognitive and physical impairments in children.
