On "1976: Legionella Rears Its Ugly Head"

Legionella didn't start as a plumbing problem—it became one because nobody understood water systems well enough to know what they were breeding. The 1976 outbreak was the wake-up call that forced the industry to confront what happens inside pipes and cooling towers when you're not paying attention, and it should've killed the habit of treating water infrastructure like black-box utility. Most shops still don't think about biofilm management or temperature maintenance the way they should, even now. That's the real lesson: preventive water system knowledge stopped being optional the moment people started dying.
