I've attached a link to the EPA's most common pamphlet on lead based paint.
You can also try calling Portage County Health and Human Services. Their number is (866) 920-2525
1. Check with a doctor and see if your child has high lead levels.
2. check with cap services and see if they can help with the repairs to your foundation and painting over any peeling lead paint.
3. if you dont meet cap services criteria, then try fixing the issues yourself, do a bit of research first to see what needs to be done and if any permits are required.
