`Flint Michigan lead in drinking water`

Passing reference (Holman alludes to "all the people up in arms over the lead in school drinking water") to motivate the historical lead-pipe legacy.

Another example. Professor Eagar gave me this yesterday. He's having a renovation done on his house. Have any of you ever done any soldering, either jewelry or things like that? Everyone has plumbing, and years ago all the plumbing was joined together by lead-tin solder. Over time there were environmental restraints on the lead. You've probably seen all over the news, all the people up in arms over the lead in school drinking water — that's a result of the pipes having lead joints. And they probably actually had lead in the composition of the pipes, they're so old.
