But even then, I fear they may not have allowed it to boil the proper length of time to ensure the demise of the baddies in that water, but probably just got it to boil, and then immediately used it to make tea.

Nothing like dipping a kettle into a splashing running beck, then the next day, to discover the remains of a dead sheep some hundred feet upstream of the dipping point. Boiling does not sound all that sufficient any more.

According to the US Environmental Protection agency's 'Emergency Disinfectaction of Drinking Water' website.

Vigorous boiling for one minute will kill any disease-causing microorganisms present in water (at altitudes above one mile, boil for three minutes).

These days I would be more worried about heavy metals from detergents; agro chemicals including pesticides and dumped sheep dip; and the odd smiggen of Sellafield plutomium blown back from the Irish Sea.
