I have a sink in my lab that has a placard saying "Industrial Water, Non-Potable" and my question is, what exactly is industrial water? There's an office upstairs that has 'real water' in it. Is industrial water unclean, does it have heavy metals in it? Is it run with cheaper pipes, or do they get their water from a different source? Is it really cheaper to run a whole different set of piping throughout the building just to use different water in the labs? An even then, why would water that's not okay for my GI tract be okay for cleaning beakers or washing hands?
Curious. h
