152 The One Where We Talk More About Legionella

We are in the middle of Legionella Awareness Month. The goal of devoting a month of episodes to Legionella is to raise the bar on our water treatment knowledge when it comes to Legionella. On many shows, I ask how you are learning new things. It is effortless to become complacent with our current knowledge and not actively seek more. A day that I don’t learn something new, I consider a failure.
