Non-Potable Water Symbol (Apple)

On Apple devices, the non-potable water emoji is depicted as a clear droplet with a stark red 'X' superimposed, executed with Apple's characteristic high-gloss finish and precise 3D rendering. The sharp contrast and clean lines emphasize its meaning of caution and prohibition, typical of Apple's intuitive icon design. This symbol, as it appears on Apple devices, is universally understood to warn against unsafe water or to signify something undrinkable.
