The question is, if not recycled water, then what?
Ther is no choice of "pure", the only "pure" water is distilled, and that's not good for you. There are impurities in every mouthful of water or food. It's a matter of degree.
If you get paranoid about ppm of urine in water, don't even think about what's in any other drink. Or what was spread on your vegetables down on the farm. Or where eggs come from.
General summary -- there are no reputable, English-language studies that can back up the assertion that drinking distilled water is harmful. I can not speak to the non-English language studies.
Would you (or do you) drink recycled water?
