BOIL WATER ADVISORIES & BOIL WATER ORDERS
During boil water advisories or boil water orders, you should boil all water used for drinking, preparing food, beverages, ice cubes, washing fruits and vegetables, or brushing teeth. Severely immunocompromised individuals should always boil their tap water for the purposes noted above. Infant formulas should be prepared using boiled tapwater, at all times. In the event that boiling is not practical, your local public health authority or other reponsible authority may direct you to disinifect the water using household bleach, or to use an alternative supply known to be safe.
It is not necessary to boil tap water used for other household purposes, such as showering, laundry, bathing, or washing dishes. Adults, teens, and older children can wash, bathe or shower; however, they should avoid swallowing the water. Toddlers and infants should be sponged bathed.
How To Properly Boil Tap Water
Water should be placed in a heat-resistant container or in an electric kettle without an automatic shut-off and brought to a rollilng boil for 1 minute to kill all disease-causing organisms. Water can also be boiled in a microwave oven using a microwave-safe container, but it is advisable to include a glass rod or wooden or plastic stir-stick in the container to prevent the formation of superheated water (water heated above its boiling point, without the formation of steam). The water should then be cooled and poured into a clean container or refrigerated until you are ready to use it. At elevations over 2,000 meters water boils at a slightly lower temperature and should therefore be boiled for at least 2 minutes to kill all disease-causing organism.
Water Treatment Devices
Water treatment devices designed to improve the taste and odour or chemical quality of the water such as activated carbon filters, it is still necessary to boil the water. Devices designed to disinfect the water, such as a UV light units, may be used as an alternative to boiling. If the water is cloudy, filtration my be required before disinfection. Check with the manufacturer if you are not certain.
