Particularly if an individual is in a remote area, far away from any medical help, this can prove fatal.
Purification of water can be attempted in various different ways. Boiling is often used and this does kill viruses, cysts and bacteria. It does not deal with noxious chemicals and dirt, often having a foul taste. Filtration is often used too and this can be more or less successful, depending upon the efficacy of the filter or filters used. Using chemicals or UV lights are other options.
