Residents of Sargent in central Nebraska are under a boil order after E. coli bacteria and Coliform have been found in their drinking water.
The boil order comes after a previous order was lifted in late October.
Health officials say a water sample taken from a location in September tested positive for E. coli. A second sample, taken from another location in November, tested positive for Coliform.
The boil order will remain in effect until 10 samples total come back clean. Health officials say five clean samples must be taken from each location, 24 hours apart.
