Residents of Pittsburgh's northern neighborhoods and Reserve Township can again use water from their faucets. The Pittsburgh Water and Sewer Authority announced Thursday evening that the precautionary flush and boil advisory instituted Monday had been lifted.
The advisory has not been lifted in Millvale, however, where additional tests are required to verify that the water is safe.
In a statement, PWSA said officials from the Pennsylvania Department of Environmental Protection had tested the water from the affected regions and that the results showed "no trace amounts of bacterial content."
The agency had said earlier this week that coliform, a potential indication of contamination, had been found at the Lanpher Reservoir in Shaler.
The flush and boil orders were announced hours after a consulting company called PWSA "a failed organization atop a dangerous and crumbling infrastructure." This is the second significant issuance of the advisory since the beginning of the year, with 100,000 customers affected in January.
