Water Boil

1. How long will the need to boil water continue?: Public notification will be given when a boil water notice is lifted. Your water utility and your local Health Department office can also give you details on how long your boil water notice might last and will advise you when it is safe to return to normal water use.

2. How do I boil my water so that it is safe to drink?: Bring water to a FULL ROLLING BOIL for 1 MINUTE, then allow the water to COOL BEFORE USE. Because water may take 30 minutes to cool, plan ahead. Make up a batch of boiled water in advance so you will not be tempted to use it hot and risk scalds or burns. Boiled water may be used for drinking, cooking, and washing.
Here's an easy way to remember...ROLL for ONE then COOL.

3. Does my in-home water treatment system provide enough protection?: No! The Department of Health does not encourage residents to rely on home treatment units. It is recommended that you use boiled (and then cooled) water or an alternate source such as bottled water.

4. What if I have a reverse osmosis treatment unit on my faucet or house?: A properly operating reverse osmosis (RO) unit can remove pathogens, including viruses, bacteria and protozoa. However there are many units available to the public through hardware stores and elsewhere, not all of which can be relied upon to remove pathogens.

5. What is an acceptable alternate source for safe drinking water?: Acceptable alternate sources for drinking water include:
• Bottled water
• Water from another public water supply (one that is not under the boil water notice)

6. Is it safe to use bottled water?: It is safe to use bottled water. Such water may be used for drinking, cooking, and washing with no further treatment. Bottled water may be preferable when boiling is not possible or is inconvenient. It is always a good idea for consumers to keep an emergency supply of bottled water on hand for just such a use.

7. What container should I use to obtain water from another location?: The container you use to get water from an alternate source or temporary water station can greatly affect your water. Never use a container that has ever held a chemical, gasoline or other fuel. Use only clean containers that you know are fit and that are free of all dirt and contaminants.

8. Can I use my water for cooking?: Any water used for food preparation or cooking needs to be from an acceptable alternate source or boiled first.

9. What if I am boiling my water as part of the cooking process?: It is more protective to boil the water first, to prevent the potential for inadequate heating. The cooking process should bring the water to a full rolling boil for at least one minute before adding the food item (for example, making pasta). If the water will be at a slight boil for a long time, then this will also be protective. For example, you may be cooking beans or boiling chicken for 10 - 20 minutes.

10. How should I wash fruit and vegetables and make ice?: Fruits, vegetables, and any other foods that will not be cooked should be washed and rinsed with boiled (and then cooled) water or water from an acceptable alternate source. Similarly, ice should be made with either boiled water or water from an acceptable alternate source.

11. Can I use my water for making baby formula or drinks?: No, not without precautions! Any water used for baby food, formula, or making beverages must be boiled (and then cooled) or be from an acceptable alternate source.

12. Is potentially contaminated water safe for washing dishes?: Hand-washed dishes: No! Use boiled (then cooled) water, water from an alternate source, or after washing with dish detergent rinse for a minute in a dilute bleach (1 tablespoon of unscented bleach per gallon of water). Allow dishes, cutlery, cups, etc. to completely air dry before use.
Home dishwasher: Yes, if the hot wash is at least 170o F and includes a full dry cycle. However, most home dishwashers do not reach this temperature. If you are uncertain of the temperature of your dishwasher, rinse in dilute bleach and completely air dry as described for hand washed dishes.
Commercial dishwasher: Yes, if it is a NSF listed washer and manufactured and operated with a heat sanitizing rinse set at 170oF that lasts for at least 30 seconds. Additional information on commercial dishwashers can be found in the fact sheets for food service establishments.
CAUTION - "Green" or "Environmentally Friendly" dish washer additives, which may be advertised as a disinfectant or anti-microbial, are weaker disinfectants and should not be relied on alone to eliminate potential pathogens.

13. Is potentially contaminated water safe for washing clothes?: Yes, unless a "Do Not Use" notification has been issued, it is safe to wash clothes in tap water as long as the clothes are completely dried before being worn. However, increased turbidity that sometimes occurs during a boil water event may discolor clothing, especially whites.

14. Can I brush my teeth with the water without boiling it?: No! Any water you ingest or place in your mouth should be disinfected by boiling (and then cooled) or come from an alternate source. Bottled water is excellent for brushing your teeth.

15. Is potentially contaminated water safe for bathing and shaving?: Unless a "Do Not Use" notification has been issued, your water may be used by healthy individuals for showering, bathing, shaving, and washing as long as care is taken not to swallow water.

16. How should I wash my hands during a boil water notice?: Generally, vigorous hand washing with soap and your tap water is safe for basic personal hygiene. If you are washing your hands to prepare food, you should use boiled (then cooled) water, bottled water, or water from another acceptable source for hand washing.

17. Should I use hand sanitizing lotion or wipes?: Hand sanitizing wipes alone are not enough, especially to clean your hands for making food. Alcohol based sanitizers work against some common germs (like E. coli, and Salmonella) but may not be effective for cryptosporidium and bacterium spores.

18. Is the water safe to give to my pet?: To be certain, give them water that has been boiled then cooled or water from an acceptable alternate source. Many pets regularly drink some pretty bad water, but pets come in a wide variety with variable resistances to pathogens. Many pets are vulnerable to the same diseases that humans can get from contaminated water and can spread these diseases into the environment or pass them on to their owners. More specific information may be available from your veterinarian, based on the actual animal and conditions for the boil water notice.

19. Does a boil water notice affect how I can use my toilets?: There is no need to disinfect water used for flushing.

20. What if I have already consumed potentially contaminated water?: The likelihood of becoming ill is low. However, illness is certainly possible, especially for people that have a chronic illness or may be immunocompromised. This is why boil water notices are issued.
