This note is about simple treatment of drinking water at point-of-use for people in, or just after an emergency. The options suggested are quick short-term measures to provide a safe survival level supply of drinking water from unsafe polluted water sources. The options should be sustainable until a longer- term safe and costeffective supply is available to the population. The methods described are suitable for water taken from any source but, in general, will only remove physical and microbiological pollution. Pollution by chemicals such as after a spillage of industrial waste will not normally be removed by these processes and specialist advice should be taken.
