The Municipal Authority of Westmoreland County is asking about 50,000 households, mostly north of Route 30, to boil their drinking water until further notice.
Water collected Wednesday at the George R. Sweeney Water Treatment Plant showed a possible deficiency of the filtration barrier, the municipal authority said.
Authority spokeswoman Gina Cerilli said a malfunction at the plant caused concern, not a contamination of the water. The authority began flushing water and adding chlorine tonight, she said.
It is unclear when the advisory would be lifted, Ms. Cerilli said.
Water — such as that used for drinking, making ice, brushing teeth, washing dishes and preparing food — should be boiled for a minute and then cooled, the authority advises.
White Oak is the only community in Allegheny County affected.
Many schools also are closed: Kiski Area, Apollo-Ridge and Leechburg Area schools districts announced on their websites their closure today. It was not immediately clear how many other districts may have canceled classes because of the advisory.
Other affected communities include:
