Mold problems can be a difficult battle to fight even for parents. For the elementary school library I mentioned, parents tried for a year to get changes made. Some just exempted their kids from going to the library. They did get some press, but not a lot. Then a family moved to the school with a parent who was a lawyer with experience in the area. They got professional testing done and sent lawyer letters. The school board moved pretty quickly after that. (It was a portable building, so tearing it down and rebuilding was cheaper than gutting the inside walls and ceiling.)
