Lincoln has lifted a boil water order for customers in the city.
On Wednesday, the North Dakota Department of Health required the city to issue a boil water order after the water supply in a home tested positive twice for E. coli bacteria.
In a news release Friday morning, city officials said the issue has been resolved and all bacteriological samples sent to the state Department of Health's lab were satisfactory.
Greg Wavra, manager of the Department of Health's Drinking Water Program, said a water inspector will be in Lincoln next week to further investigate the source of the contamination and conduct a full city inspection.

"At that time, we probably will have a little more information to try to determine where it came from. Most likely this was ... just premise plumbing within the house, but as to what caused it, that we were not able to actually define," he said.
Lincoln has been dealing with water issues for several months after a water tank was damaged and a valve was replaced. Wavra said no issues have been linked to the tank replacement, but a follow-up inspection will be done "so everybody’s feeling secure."
