Water pressure keeps pollutants from entering the underground pipes that bring drinking water to your house or business. When the pressure is lost, contaminants can seep into the pipes. This might allow pathogens (disease-causing germs) into the water that can cause illness if one drinks it or prepares food or beverages with it. Therefore, as a precaution, it is important to disinfect tap water to kill any bacteria or viruses that may have entered the water, or use an alternative source of water (bottled water). If tests show actual contamination with bacteria, these same steps will make your water safe to drink. Under a precautionary boil water notice (PBWN), water used for consumption can be disinfected by any one of the following methods:
• Bringing the water to a rolling boil and holding it there for one (1) minute
• Using a disinfecting chemical. If you cannot boil water, you should put eight (8) drops of common household bleach (unscented) which is about 1/8th teaspoon, into one (1) gallon of tap water, then shake it, and allow it to stand for 30 minutes before drinking. If the water is cloudy, use sixteen (16) drops, about ¼ teaspoon of bleach instead of 8 drops, shake it, and let it stand for 30 minutes. There should be a light chlorine odor. Use common household bleach that has 5 to 6% active ingredients. Use food grade containers.
• Using water purification tablets, or iodine that many sports and camping stores sell.
You can also buy commercial bottled water for consumption and food preparation as an alternative, and use tap water you have safely stored before the emergency in clean sanitary food grade containers.
Consumption includes brushing teeth, washing fruits and vegetables, and homemade ice, water used for showering, baths, shaving and washing, so long as care is taken not to swallow or allow water in eyes or nose or mouth. Children and disabled individuals should have their bath supervised to ensure water is not ingested. The time spent bathing should be minimized. Though the risk of illness is minimal, individuals who have recent surgical wounds, are immunosuppressed, or have a chronic illness may want to consider using bottled or boiled water for cleansing until the notice is lifted.Businesses and non-residential sites should take steps such as posting notices at, or disabling water fountains and ice machines during the PBWN. After the water system is repaired, and the pressure is restored in the pipes to your home or business, the precautionary boil water notice will remain in effect for one to several days while bacteria tests are conducted to assure the safety of the water. It may be lifted in sections of the city/county as those pipes are cleared and the water deemed safe to drink. The media will be provided information updates and you should listen for this important information on the radio and/or from the television. Flush your taps and dispose of ice made during the PBWN.
The County Health Department can provide answers to specific health related questions.
