Unless your tap water comes from a glacier, well or rain-fed and/or underground aquifer (the underground aquifers are rapidly being depleted and polluted, BTW, placing the potable water supplies of millions in the U.S. at risk), you are drinking some percentage of purified toilet water.
And not just purified as in via the water cycle that means we all likely have some water in our bodies that was once in someone famous/cool/and/or long dead, but “purified” in the sense of filtering the chunks out, running it through a few other, finer processes, and adding a bunch of chlorine to kill the shit-bugs.
Is it the majority of us? Maybe not (yet). I don’t know the exact percentages. But a significant number of us? Sure.

" A vast array of pharmaceuticals - including antibiotics, anti-convulsants, mood stabilizers and sex hormones - have been found in the drinking water supplies of at least 41 million Americans, an Associated Press investigation shows…In the course of a five-month inquiry, the AP discovered that drugs have been detected in the drinking water supplies of 24 major metropolitan areas - from Southern California to Northern New Jersey, from Detroit to Louisville, Ky…How do the drugs get into the water?..When people take medicine some gets absorbed by the body, but the leftovers end up getting flushed down the toilet and into the water supply. Some of the water is cleansed again at drinking water treatment plants and piped to consumers. But most treatments do not remove all drug residue."
“leftovers”= residues in piss and shit as well as drugs dumped into the toilet…it ends up BACK in the tap water piped into your home.
If we had state of the art mass purification methods that could take waste water and turn it into the stuff I can buy for .35 a gallon and send it through the often crumbling, lead-leaching pipes…ok, so THOSE have to be replaced as well…I would feel very differently about tap water as a general concept.
Maybe if we advanced beyond shitting where we drink (composting toilets, say, which are odorless, clean and return rich compost to the soil, rather than using fresh, potable water to flush away our waste, something we may be forced to do soon as fresh, potable water becomes ever more valuable) this wouldn’t be an issue.
