Well, I don't think anyone intentionally used "less safe" water. Relatively "safe" water is something we take for granted in the modern, western world. We didn't always have water filtration or chemicals to remove or kill pathogens in water. We didn't always have the technology to dig water wells deep enough that they'd be safe from contamination.
When have you ever heard of a cholera outbreak in the US? This was something that happened much more often in the past, and still does in places where there's deficient sanitation infrastructure.
Drinking tea was a safe way to get hydrated because the water would be boiled. Likewise with beer. Beer would also be something you could store safely because it contained alcohol and often preservative herbs. The fermentation itself
may also render the beverage safer to drink.
Of course now our problem isn't so much pathogens in water, but rather chemicals of the industrial era.
