E. coli bacteria or high turbidity in drinking water are the cause of most of the boil orders issued in Missouri. The water systems listed in the report of current boil orders have either a confirmed danger or the conditions present that could pose an immediate threat to public health. Affected consumers should boil their drinking water for three to five minutes, which should kill any microbes present.
The report of current boil orders does not include precautionary boil water advisories. Boil water advisories are issued by public water systems as a precautionary measure. The most common cause of these precautionary advisories is water main breaks.
If you hear of a boil water order or advisory that affects you, but is not on this list, the department urges you to take all precautions as instructed by your public water system.
The Report of Current Boil Water Orders in Missouri lists current boil water orders issued by the department according to the report issue date. A Map of Current Boil Water Orders in Missouri has also been provided to show the approximate location of the listed boil water orders.
Note: The county and the nearest town are provided for each water system solely as a locational reference point for the purpose of helping viewers determine the location of the system. The boil order applies only to the listed water system, not the county or the nearest town.
