I once heard someone say you can detect PFAS by looking for an oily film on top of your water. Let me stop you right there—that is pure nonsense. That film is usually just minerals, dust, or leftover soap from your dishwasher. I fell for this myth once and spent a whole afternoon staring at my glass like it was a crystal ball. Spoiler: I didn’t see a thing.
PFAS aren’t greasy like bacon grease. They dissolve completely, which is why they’re so good at hiding. They’re the ninjas of the chemical world.
