HASTINGS, MN — Authorities have detected E. coli bacteria in part of the Hastings public water system and have issued a boil advisory. Residents living outside of the affected do not need to follow the advisory and can use water as normal.

Check the map to see if you live in the affected area.

If you live in the affected area, city authorities say you should not drink water before boiling it, or use a safe alternative source:

Bring all water to a full, rolling boil, let it boil for one minute or longer, and let it cool before using, or use bottled water. Boiled or bottled water should be used for drinking, making ice, brushing teeth, and food preparation until further notice. Boiling kills bacteria and other organisms in water.

City workers will add chlorine to the water system this weekend. The issue is expected to be resolved in the next three to five days.

“Addition of chlorine to disinfect water may react with iron and/or manganese that may be deposited in water mains, breaking it loose and causing some temporary discoloration of water,” officials said Saturday.

“This could cause a black or reddish-brown color, but it does not present a health threat. Consumers may want to let water run for a few minutes to flush plumbing of discolored water before using it for cooking or laundry. Fish tanks and bait shops should not use chlorinated water in tanks for this period of time. You may notice city staff flushing fire hydrants around the city to move chlorinated water through the system. We anticipate resolving problem within 3 to 5 days.”

Officials have not indicated the origin of the contamination.
