Originally posted by savoche When we're away from populated areas we fetch our drinking water straight from the streams. In the lowlands you want to know where the stream originates, though. In the mountains, drink and be happy.
Except if there's a dead animal a short walk upstream lying in the stream bed.
There's also Primary meningoencephalitis, in geothermal water, which is rare, but happens here. Symptoms begin with a change in taste or smell, followed by headache, nausea, vomiting, confusion, fever, stiff neck and mental acuity changes. The infection typically affects the olfactory bulb and grey matter of the frontal, temporal and cerebellar lobes and usually runs a rapid course with death within 6 days of onset of symptoms. There is no cure.
