The state Department of Environmental Protection has ordered an Aspinwall boil water advisory be extended until Friday afternoon.

The advisory was prompted after maintenance work on a pump caused low or no water pressure to about half of the borough’s 1,200 water customers.

Under the advisory, residents are encouraged to boil water for drinking and cooking.

“Though it is very inconvenient, we are leaning to the side of caution,” the borough said.

Borough officials were alerted to the water problem Wednesday morning by customers reporting low or no water pressure and brown or discolored tap water in an area below Eighth Street. That loss of water pressure was caused by Pittsburgh Water and Sewer Authority workers who shut down a PWSA pump in Blawnox or O’Hara. The borough gets its water from the PWSA.

Borough manager Melissa Lang O’Malley said the Allegheny County Health Department is conducting water quality tests for two days before the advisory is lifted.

Borough officials said residents should check for updates on the advisory via the Aspinwall website and Facebook page.
