Boston (WBZ Newsroom) -- The state Department of Environmental Protection has issued a boil water order for Gloucester until further notice.
Residents are being advised to boil tap water for at least one minute before drinking or using for purposes of human consumption, such as cooking, ice-making, dishwashing or teethbrushing.
In addition, residents are being told to get rid of any ice, juice, formula and uncooked foods that were prepared with water from the Gloucester water system after August 15, 2009.
DEP says the most recent water samples have not tested positive for e-coli or fecal bacteria.
However, the department says chlorine levels in some areas remain low and pose a risk of the introduction of harmful bacteria.
Testing will continue throughout the weekend.
The city's outdoor water ban is still in effect and Gloucester residents are urged to continue conserving water until further notice.
Meanwhile in Milford, the boil water order now has been lifted for the entire town.
It was lifted for most of the town earlier this week, but had remained in effect for the Upper Purchase Street area.
DEP says the water supplied by the Milford Water Company is now safe to drink.
