This really sucks for the children and the families affected. They could sue the developers, but no amount of money is going to compensate them for the health issues these kids are going to experience due to lead poisoning. The worst thing about this is, if it were a wealthy white neighbourhood adjacent to the industrial site they wanted to demolish, you know they would have taken every precaution to test to see if there was any chance of releasing toxic amounts of lead into the vicinity. But it's a poor black neighbourhood, so of course they aren't as careful.
