The city plans to finish replacing lead pipes by 2076, conducting replacements at a rate of 8,300 per year for 50 years. That's 30 years past the EPA's deadline. At this pace, kids born today will be middle-aged before Chicago's water is safe. 5/n

In the meantime, nearly 70% of Chicago kids under 6 live in homes with detectable lead in their tap water. As readers probably know, there's no safe level of lead exposure: It causes developmental delays, learning difficulties, and permanent health problems. 6/n

  1. And while Chicago is supposed to notify 900,000 at-risk households about their lead pipes, as of July, they'd only sent out 62,000 letters. More than 90% of residents with dangerous pipes still don't know they're at risk. That's one reason we built our lookup tool. 7/n

    Infographic titled "What material is your water service line?" showing Chicago's four-category classification system for water service lines. The graphic displays four pipe illustrations with colored backgrounds: 1) Lead pipe (gray pipe with red background) - at least one component known to be made of lead; 2) Suspected Lead pipe (gray pipe with red background) - composition marked unknown but suspected to contain lead based on building age; 3) Galvanized Requiring Replacement pipe (lighter gray pipe with red background) - no lead components known, but galvanized steel that can become contaminated with lead from upstream pipes; 4) Non-Lead pipe (copper-colored pipe with blue background) - no components made from or contaminated with lead. The graphic explains that Chicago classifies entire service lines based on knowledge of three components: the gooseneck connecting to the water main, the public-side line under the sidewalk, and the private-side line running into the building.
