PITTSBURGH — Officials are advising about 120,000 people to boil their water because a faulty filter may have caused contamination.

Residents in part of Westmoreland County are being advised to boil water until Monday or Tuesday.

The Department of Environmental Protection said the water contained algae that shouldn't be there, and they ordered the Municipal Authority of Westmoreland County to increase chlorination and flush the system.

The Kiski Area, Apollo-Ridge and Leechburg schools districts announced on their websites that they would be closed Friday.

Officials say water used for drinking, making ice, brushing teeth, washing dishes and preparing food should be boiled for a minute and then cooled.
