Unsafe Water Sources
Never use water from the sources listed below for drinking.
- Hot water boilers (home heating system)
- Water beds (fungicides added to the water or chemicals in the vinyl may make water unsafe for use)
Water for Drinking and Cooking
Safe drinking water includes bottled, boiled, or treated water. Your state, local, or tribal health department can make specific recommendations for boiling or treating drinking water in your area. Here are some general rules concerning water for drinking and cooking. Remember:
- Do not use contaminated water to wash dishes, brush your teeth, wash and
prepare food, or make ice.
- If you use bottled water, make sure the seal has not been broken. Otherwise,
water should be boiled or treated before use. Drink only bottled, boiled, or
treated water until your supply is tested and found safe.
- Boiling water kills harmful bacteria and parasites. Bringing water to a
rolling boil for 1 minute will kill most organisms.
- If you can't boil water, you can treat water with chlorine tablets, iodine tablets, or unscented household chlorine bleach (5.25% sodium hypochlorite). If you use chlorine tablets or iodine tablets, follow the directions that come with the tablets. If you use household chlorine bleach, add 1/8 teaspoon (~0.75 milliliter [mL]) of bleach per gallon of water if the water is clear. For cloudy water, add 1/4 teaspoon (~1.50 mL) of bleach per gallon. Mix the solution thoroughly and let it stand for about 30 minutes before using it. Treating water with chlorine tablets, iodine tablets, or liquid bleach will not kill many parasitic organisms. Boiling is the best way to kill these organisms.
Containers for water should be rinsed with a bleach solution before using and reusing. Use water storage tanks and other types of containers with caution. For example, fire truck storage tanks, as well as previously used cans or bottles, can be contaminated with microbes or chemicals.
