Transcript for Indiana Community Forced to Leave as a Result of High Lead Levels
Next to Indiana, where an entire community is reeling after learning their homes will soon be demolished. They were built over a lead plant. Alex Perez is there tonight with the families looking for answers. Reporter: Tonight, fear and anger spreading through this public housing complex in east Chicago, Indiana, where families are learning that lead and arsenic levels are dangerously high. So high that the mayor is now calling for all residents to relocate within 90 days. Instead of playing outside, most kids here are kept inside in hopes of keeping contaminated soil and dust from getting in homes and into their bodies. It's upsetting to watch them stare out the window, because they can't go outside. Reporter: Shantel Allen, who's lived here for six years, says all five of her children have tested positive for lead. They experience headaches, they experience stomach cramping, they vomit. Reporter: This housing complex, home to 1,100 people, has long been known to be contaminated. It was built in 1972, on land that was once a lead smelting plant. Documents show EPA investigators found hazardous levels of lead in some areas in 2008. At the time, officials performed some clean-up, but new test results revealed in may that chemical levels on the surface of the soil here were up to 30 times the limit considered safe. The city is now planning to demolish the community. If they knew that it was dangerous, we should have known a long time ago. Alex, some money has already been approved to help the families find new housing, but more is needed to help? Reporter: That's right. Residents here will get rent vouchers from the federal government, and $100,000 has been approved to help with moving expenses. But an additional $500,000 is needed.
