You're right; it isn't a common event, but it has a non-zero

The bad news is that in Cary NC a couple of years ago, everyone had
to use bottled water due to contamination by bad plumbing at one

That would be the non-zero part of the problem.

The hose in the pool is really low-danger. The guy spraying for bugs
with a hose-end sprayer is more of a danger. A little extra chlorine or
algae won't cause much havoc. A dose of insecticide in the water main
has a much larger negative potential.
