Officials with the Municipal Authority of Westmoreland County are hopeful that a boil-water advisory for residents of Port Vue and McKeesport's 10th Ward could be lifted on Thursday.
Matthew Junker, authority spokesman, said MAWC is waiting for test results of a water sample taken Wednesday morning. The test --- checking for possible contamination --- takes 24 hours.
"If we get the results we expect, and the (state Department of Environmental Protection) gives approval, it could be lifted in the A.M.," Junker said.
About 2,100 customers have been under the boil-water advisory since Tuesday morning, when the authority detected a loss of water pressure and found a broken six-inch water main on Joy Street in Port Vue.
The water line was repaired later that day, but the authority was concerned that with a loss of pressure, contaminants could have entered the public water supply through back-flow into a line.
MAWC is advising all customers in the affected areas to continue to boil their water, and bring it to a rolling boil for at least one minute, before using it to cook, make ice, brush their teeth or wash their dishes.
The advisory remains precautionary, Junker said, "meaning no contamination has been found."
Some residents reported a loss of water pressure following the break, or rusty-colored tap water for a brief time. One Tube City Almanac reader in Port Vue described it as looking "like weak coffee."
Water buffaloes were placed Tuesday afternoon at the Port Vue borough building and the Vigilant Hose Co. fire hall on Romine Avenue.
