If you cannot boil your water, mix eight drops (1/8 teaspoon) of unscented, ordinary household chlorine bleach per gallon of water. Mix the solution thoroughly, and let stand for about 30 minutes before using.
When your boil-water notice is lifted:
Flush any faucet a minimum of 2 minutes to ensure clearing of the line serving the faucet.
If water systems lose pressure, MSDH or the water system will issue a boil water notice. However, if you notice a loss of water pressure, you should boil your drinking water until you have been notified your water is safe. Bringing water to a rolling boil for one minute will kill most organisms. MSDH will test water samples collected from water supply systems and must have two consecutive days of clear test samples. Typically, it takes a minimum of 48 to 72 hours to find out whether water is safe to drink from contaminated water supply systems.
The water may be used for showering, baths, shaving or washing, as long as one does not swallow the water or allow it in the eyes or mouth. Parents should supervise children to make sure water is not ingested, and caregivers should supervise disabled individuals for the same reason. Those with recent surgical wounds, who have a chronic illness or are immunosuppressed should consider using bottled or boiled water for bathing until their boil water notice is lifted.
Do not use contaminated water to wash dishes, brush your teeth, wash and prepare food or make ice. Make sure to boil or disinfect water before use (see above). Drink only bottled, boiled or disinfected water until your water supply system is tested and found to be safe.
Fruits and vegetables should be washed with boiled (then cooled) water, bottled water or disinfected water as described above. Ice should be made with boiled, bottled or disinfected water.
Again, you should not use contaminated water to wash and prepare food or make ice. If you use bottled water, make sure you know where it came from. Otherwise, water should be boiled or disinfected before use.
The major organisms of concern are bacteria such as E. coli and Shigella. These organisms primarily affect the gastrointestinal system and cause diarrhea, abdominal cramps, nausea, and vomiting with or without a fever. These illnesses can seriously affect the health of the elderly, very young or those who are immunocompromised.
If you use bottled water, know where it came from. Otherwise, water should be boiled or disinfected before use. Drink only bottled, boiled or disinfected water until your supply is tested and found safe.
It is important to disinfect both the well and plumbing with chlorine bleach to ensure that all infectious agents are killed. If you have water treatment devices, remove all membranes, cartridges and filters and replace them with new membranes, cartridges or filters after the chlorination process is completed.
The amount of chlorine and the length of time you allow it to remain in your system are equally important. Common unscented laundry bleach can be used effectively as a chlorine disinfectant.
Individual water systems issue precautionary boil-water alerts when water pressure is lost. Water systems are responsible for notifying their customers directly using whatever means necessary when a self-imposed boil-water alert is issued.
When water testing by the state Public Health Laboratory indicates problems related to water quality, MSDH immediately issues a boil water press release and informs the local water system. For state-issued boil-water alerts, the water system is responsible for notifying customers directly using whatever means necessary.
In addition to posting state-issued alerts on this site, if notified by water system officials, MSDH will also post self-imposed alerts. MSDH will issue press releases to radio, television, and newspaper in the affected area to supplement the public notification efforts of the water system.
You can contact the MSDH Bureau of Public Water Supply by calling (601) 576-7518.
