It’s a specious argument on its face. “We know that lead is a powerful neurotoxicant, that there is no safe level,” and then go on doctorsplain us why the kids are safe.

And they try to define the length of exposure to when the water source was changed. That might be true but they can’t know that. And it’s likely not true, a water system with lead pipes will have specified an acceptable lead level that can be present in safety samples. Even though there is no safe level.
