Not going to start a new thread, but here is a question with a serious tone.
Was out walking around Elterwater. Got round to Slaters Bridge which crosses a stream that feeds out of Little Langdale Tarn.
As I sat there under the tree by the stream,along came a couple with a teenage child and promptly grabbed handfuls of water from the stream,and drank heartily. Mrs RT told me to keep my gob shut, and not pass comment in the general direction of said couple. The question I have to ask is this.
Are they going to die?
I drink from rivers and streams all the time when in the hills and have done for over 50 years. However I usually leave it until higher up than Little langdale Tarn, although have on occasions taken stream water lower down with no ill effects.
The only time I have suffered bad effects from water was in Nepal, probably due to the water in Tea from a Tea House not being boiled long enough. Ended up with Asian Cryptospiridium, a bit like a tornado ripping through your intestines for three weeks. Became an expert at making a 'Plug' and improvised Nappy.
