[00:01.51] Lesson 38
[00:03.45] Water and the traveller
[00:11.95] What does this text describe?
[00:16.88] Contamination of water supplies is usually due to poor sanitation close to water sources,
[00:23.71] sewage disposal into the sources themselves, leakage of sewage into distribution systems or contamination with industrial or farm waste.
[00:34.92] Even if a piped water supply is safe at its source, it is not always safe by the time it reaches the tap.
[00:43.24] Intermittent tap-water supplies should be regarded as particularly suspect.
[00:49.68] Travellers on short trips to areas with water supplies of uncertain quality
[00:55.51] should avoid drinking tap-water, or untreated water from any other source.
[01:01.52] It is best to keep to hot drinks, bottled or canned drinks of well-known brand names-
[01:07.76] international standard of water treatment are usually followed at bottling plants.
[01:13.72] Carbonated drinks are acidic, and slightly safer.
[01:17.82] Make sure that all bottles are opened in your presence, and that their rims are clean and dry.
[01:25.14] Boiling is always a good way of treating water.
[01:28.87] Some hotels supply boiled water on request and this can be used for drinking, or for brushing teeth.
[01:36.44] Portable boiling elements that can boil small quantities of water are useful when the right voltage of electricity is available.
[01:45.31] Refuse politely any cold drink from an unknown source.
[01:50.80] Ice is only as safe as the water from which it is made,
[01:54.55] and should not be put in drinks unless it is known to be safe.
[01:59.25] Drinks can be cooled by placing them on ice rather than adding ice to them.
[02:05.33] Alcohol may be a medical disinfectant,
[02:08.62] but should not be relied upon to sterilize water.
[02:12.47] Ethanol is more effective at a concentration of 50-70 percent;
[02:18.61] below 20 per cent, its bactericidal action is negligible.
[02:24.30] Spirits labelled 95 proof contain only about 47 per cent alcohol.
[02:31.21] Beware of methylated alcohol,
[02:34.07] which is very poisonous and should never be added to drinking water.
[02:39.39] If no other safe water supply can be obtained,
[02:42.72] tap water that is too hot to touch can be left to cool and is generally safe to drink.
[02:49.73] Those planning a trip to remote areas, or intending to live in countries where drinking water is not readily available,
[02:57.06] should know about the various possible methods for making water safe.
