[00:02.41]Water and the traveller
[00:09.59]What does this text describe?
[00:13.50]Contamination of water supplies is usually due to poor sanitation close to water sources,
[00:21.30]sewage disposal into the sources themselves, leakage of sewage into distribution systems or contamination with industrial or farm waste.
[00:32.17]Even if a piped water supply is safe at its source, it is not always safe by the time it reaches the tap.
[00:39.72]Intermittent tap-water supplies should be regarded as particularly suspect.
[00:45.76]Travellers on short trips to areas with water supplies of uncertain quality
[00:51.08]should avoid drinking tap-water, or untreated water from any other source.
[00:56.95]It is best to keep to hot drinks, bottled or canned drinks of well-known brand names-international standard of water treatment are usually followed at bottling plants.
[01:08.27]Carbonated drinks are acidic, and slightly safer.
[01:12.24]Make sure that all bottles are opened in your presence, and that their rims are clean and dry.
[01:19.14]Boiling is always a good way of treating water.
[01:22.36]Some hotels supply boiled water on request and this can be used for drinking, or for brushing teeth.
[01:29.49]Portable boiling elements that can boil small quantities of water are useful when the right voltage of electricity is available.
