We used to gargle water mixed with potassium permanganate as children after cleaning our teeth to see if we did a good enough job. It would colour plaque pink, so it was very obvious if you hadn't cleaned properly!
A lot of the posts here seem to be missing something important: permanganate is an EXTREMELY vividly colored ion in solution. The bright colors of the water in the pictures is about in line with what a 20 ppm permanganate solution looks like. Considering manganese is an essential trace mineral (although it is neurotoxic above a certain point, the amounts in the water are minimal), I doubt there is any real toxic effe…
But what about a small dose taken over years, and interacting with the thousands of small doses of synthetic chemicals we have in our body because of processed food, hygiene products, clothes, surface treatments and medicine ?
This we have no way to know.
There are already so many reasons to get in contact with synthetic chemicals. I think it's sane policy to limit them a much as we can when we can, especially in something as ubiquitous as water.
Yes having drinkable water is essential, but some cities manage to have it with much less additives. It should be the default goal for anything related to public health.

When I was a kid I was visiting my aunt who lived outside of Denver. I was walking around their property and on the other side of a fence was a stream which was exactly this color. I've always wondered what the deal was
Same colour, but not the same texture

There is probably not "any real toxic effect" with a small dose taken over a few months in an isolated study. But what about a small dose taken over years, and interacting with the thousands of small doses of synthetic chemicals we have in our body because of processed food, hygiene products, clothes, surface treatments and medicine ?

I'm up in Yorkshire, our water is so hard it beats up the kettle, pipes, taps and washing machines on the way through.
I used to live in Leeds and used the water for a few gardening projects were the PH of the water was very important so was also testing it, it was always perfect, never had to modify. Now, when I lived in Hull, terrible water

This type of response is exactly what is wrong with the world, in my opinion. The attitude of "Oh that's absolutely demonstrably awful, here's X to subsidize your life," needs to stop. How about we create societies where the onus of providing clean drinking water to humans is not arguable?
Not sure if you misunderstood the article. The article indicates that potassium permanganate is what caused the water to be pink. The commenter is explaining that potassium permanganate is harmless and usually used as a water purifier anyway. I have no idea how that can be interpreted as "Oh that's absolutely demonstrably awful, here's X to subsidize your life,"
I should have been more diligent and usually am.
I was projecting other feelings from previous arguments and this isn't the place for it and I deserve those down votes as it clearly wasn't a super helpful addition to the discussion.
Sorry and thanks.

We used permanganate when I was in grad school to clean glassware of organic residue. Concentrated it is extremely good at it. At such minimal concentration its not an issue.
