'Very, very pink' tap water in Alberta town

What's the concentration of that vs the concentration here. Note that we also use chlorine to treat drinking water (e.g. on canoe trips), but you don't want to be drinking that unless it's very low concentration.

A quick google search suggests that they are used to "improve water clarity" [0], so at a guess you don't use enough of it to turn the water pink.

There's also the fact that they think it's concentrated enough that you should avoid bathing in it if you have sensitive skin. That certainly doesn't inspire confidence that you should drink it (exposing some very important skin, that's usually more sensitive).

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?

I would not use livestrong as a source.

If the pictures are true to the situation, the concentrations are tiny. You can look up videos of people putting less than a teaspoon into water to get the same result.

IIRC, PP can be a precursor to chlorine. But, you're comparing two different chemicals here and what applies to one likely doesn't apply to another.

There is a chance your skin will feel like it's burning if it's not fully dissolved in water. I wouldn't advise touching the dry powder. The shards will embed into your skin and it will feel like an open wound filled with Tabasco for a long time.

Fun-fact: If you mix it with glycerol it combusts, so don't use any lotions with it if you get some on your skin.

ETA: I don't know what's going on, but there's a lot of low-effort responses in this thread. Is it the hours?

Are you saying this from a point of experience or a point of caution?

PP-treated water is safer than chlorine-treated water.
