The boil water advisory in Burlington's South End has been lifted.

City officials say sample results came back Wednesday morning and showed no indication of contamination.

About one-fifth of the entire city woke up Tuesday to the boil water notice after the city said work on a waterline had caused the system to depressurize.

Many businesses, including City Market, were forced to close their doors for the day.

Officials say the advisory-- the first in memory-- was issued out of an extreme abundance of caution and to comply with a recent change in state regulations.
