"All toilet paper from across the globe checked for toxic PFAS “forever chemicals” contained the compounds, and the waste flushed down toilets and sent to sewage treatment plants probably creates a significant source of water pollution, new research has found.
Once in the wastewater plant, the chemicals can be packed in sewage sludge that is eventually spread on cropland as fertilizer, or spilt into waterways".

Something that stands out to me in this article is the little bit about human sewage being used on crops, wait, what?
"Human Sewage Sludge in Compost? It’s Really a Thing (and BEWARE)
If you don’t want to wind up with shampoo chemicals in your garden tomatoes, this information is for you. Now, I get it. When you swing by your local home improvement store for bagged fertilizer for your lawn or garden, the last thing you’re probably thinking about is toxic compounds. But there’s something you need to know. Human sewage sludge in compost is common and often marketed as “organic” despite chemicals sneaking into the mix.
This “sludge” is the biosolid product leftover in wastewater treatment plants. In theory, using human waste as a nitrogen-rich, natural fertilizer seems logical, but it’s not that simple today. Why? Think of all of the things that go down the drain and into wastewater plants: everything from shampoo and antibacterial soap chemicals to medication residues and more. And it’s not just what’s drain-bound from U.S. homes, either. Waste from mortuaries, hospitals, industry and businesses also winds up in wastewater treatment plants and often in the leftover sludge, too".
