Lead poisoning

While reading "Their son got lead poisoning and the city treated them like slumlords." I understood that the city does not care. It wasn't even their fault. Not only was it not their faults but they called for help and didn't get a phone call back. Then their kids had to suffer with high levels of lead in their system. Also I understand that Philadelphia is dealing with a problem and no help is being put out there. I wonder if it's just more than that one Lead poisoning program to help with that. I also wonder what are the doctors doing to get the children lead levels lower. This is something that needs to be helped with especially because it's involving children.
