Most places are smart enough to not falsify water test reports so they can skimp on pH balancing treatment so the water isn't acidic to save literal pennies. The water coming in was acidic enough for the local hospitals to complain about their stainless steel sinks rusting from it. Even if there was no lead in any of the pipes they would have had to replace the entire water system because it ate right through their steel pipes which otherwise had been coated in mineral deposits to protect it.
