The number-one rule is be careful of water and ice, although both are usually factory produced, a legacy of the French. If you don’t know for certain that the water is safe, assume the worst. Reputable brands of bottled water or soft drinks are usually fine, but you can’t safely drink tap water. Only use water from containers with a serrated seal. Tea and coffee are generally fine, as they’re made with boiled water.


The tap water supply in Phnom Penh has undergone significant changes following a "water revolutionary" in the government, Ek Sonn Chan. Consequently in Phnom Penh it is said that you can drink the tap water without problem, although it is highly chlorinated and may be sluiced through old rusty or leaded pipes - drink at your own risk. Locals usually do not drink the tap water.
Outside of Phnom Penh and Siem Reap tap water should be assumed not to be potable. Cambodian branded water in blue plastic bottles sell for 1000 riels or less, although prices are often marked up for tourists to 50 cents or a dollar.
