> The infrastructure to get it that pure becomes very specialized

I think some of the most advanced fab infrastructure is the ultra pure water system. Water becomes quite aggressive chemically when it has no dissolved ions in it. You have to use exotic or highly processed materials simply to transport it around. If the factory didn't need such massive quantities of it, trucking it in would likely be preferable.

I guess you watch asianometry?

No. I worked at Samsung Austin Semiconductor during a large UPW upgrade project many years ago.

Ultrahigh density polyethylene isn't that exotic.

What about microplastics?

What about them?

They are toxic.

Well, good thing you aren't drinking it then, because the complete lack of electrolytes would kill you far faster than the microplastics. Surely if they can chemically purify the water to chip-making standards they can filter out the microplastics (when they are done with it)? At least one can hope.
