If one fountain produces far more lead than others, just replace it.

What do city officials say about that?

Is there a school district facilities manager? Really? He can'f get the fountain valves just turned off? Or the fountain covered? Time for the CEO, the superintendent, to just give him Negative Bonus. Maybe, if he gets a $2,000 cut in his public salary this year - he will take the safety of school kids a bit more seriously next time (oh yeah, these two schools are poor kid schools - no trouble)
