Current Boil Water Orders - Due to Acute Microbiological
The confirmed presence of bacteria such as E. coli or high turbidity levels lead to most of the boil orders issued in Missouri. Microbiological conditions have been found at the water systems listed that could pose an immediate threat to the public health. Affected consumers can remedy the problem by boiling their drinking water for three to five minutes, which should kill any microbes present. A list of all acute MCL violations for a given year can be found in the Water Protection Program, Public Drinking Water Branch Annual Compliance Report. This list does not include precautionary boil water advisories. Boil water advisories are issued by the local water supply as a precautionary measure.
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 in chronological order. A Map of Current Boil Water Orders in Missouri has also been provided to show the approximate location of the listed boil water orders. This list and map do not include precautionary boil advisories issued by public water systems. If you have questions about a boil advisory, please contact your public water supply.
