Residents in Windsor may have to boil their water until next week.
The town first announced the boil water order Monday after tests confirmed coliform bacteria in a water sample last week.
Wednesday, town officials say they found the source of the contamination, but that it will still take more time to clear it up. And by the time the town gets negative test results back, it could be next week.
All water used for drinking and food preparation should be boiled for at least 1 minute.
