Back in the '80s, environmentalists were bitching about the water used by Texas Instruments wafer fab plants ..
What was funny about it was that TI used 'polished' water, cleaner than could be obtained by simple distillation or ion exchange, to wash off the silicon wafers. It had to be nine-nines purity, or something like that. They ran a big water purification plant, alongside the silicon etching and doping and so forth.
Even after washing photoresist and fluorosilicic acid and etc. off the wafers, it was still far cleaner than Dallas city water. You could drink it with impunity. It was recycled in-house. Any water discharged from the plant was cleaner than the rain.
