I know one thing, the moment you say “Legionella” to a group of plumbing engineers, everyone pays attention.
It’s the likeliest word in our verbal repertoire to set off alarm bells next to the word “lead.” Ironically, “plumbum” is the base word for plumbing and also the Latin word for lead, which is now known to be a poisonous material plumbing engineers attempt to avoid at all costs. Maybe we should rename our profession to “legionell-ing” engineers, since our shift to learn as much as we can on how to avoid these bacteria at all costs. But I digress…
