You gotta flush the tap for a bit. When water is stagnant in your pipes overnight contaminants can leach into it (including lead if you have lead pipes or lead in your fixtures).

I’m a water engineer with a PhD, so not a tech nerd but definitely a nerd :) I came here mostly because I find the Reddit app annoying and the app I was using came here.

I don’t know the details about alum production (assuming that is what you are referring to), but there are many alternative coagulants available now. Sure the supply logistics would be incredibly challenging and many people would have to boil their water or use point-of-use filters, but this take is pretty doomer in my opinion. Most plants use alum because it’s cheap and easy, not because it’s their only option.

The Romans used lead as a sweetener…
