I’ve always been under the childlike impression that my tap water is clean clean, but when thinking about it today I realised that it’s unlikely that tap water is completely sterile, certainly not by the time it reaches my house through miles of pipes. So, just how unsterile can it be and still pass muster with the local government?
If we accept a certain number of rodent hairs or cockroach shells in each helping of our processed foods, I can only imagine what’s considered acceptable when it comes to tap water.
For reference, I’m in N. Ireland, which is, regrettably, the UK. But obviously the island of Ireland is where my water comes from. From this nightmarish swamp, to be precise.
Stay moist, hydrohomos.


Pure water is not good for you… You need your water to be contaminated with minerals at very least.
Also, our systems don’t like stuff to be too stesole as well, since that will make our defenses decrease over time. Being esposed to a reasonable level of bacteria and viruses is what male you stronger and build your defense.
I mean “reasonable” of course. And tap water is reasonable (at least, in developed countries so places like USA might not apply, right Flint?) clean to fit that description.
PS: there are stuff that will make you seriously sick in river and stream water, against which it’s pointless to build defences… So please don’t do that and always drink controlled water.
Fun fact, in the Alps every small village has a public fountain, where water is NOT controlled or checked, but still perfectly fine to drink specially of you have been drinking ot from young age, like I did. Others who grow up without drinking it, might feel some mild consequences if they drink too much.
I love those fountains when hiking or cycling in the alps. And I’ve never got sick from drinking that water even as a tourist.
