A Boil water advisory that was issued for some 95,000 Pennsylvania American Water customers in Washington and Allegheny Counties on Saturday has been lifted. Water company officials say water samples tested from the affected area confirm that the water meets all federal and state regulatory standards for drinking water. If you are a landlord and water service is in your name, the company is asking you to inform your tenants that the advisory has been lifted. According to company officials, a power surge early Saturday morning caused a depletion of storage at a tank near the Aldrich Water Treatment Plant in Elrama. The company says a loss of positive pressure within the distribution system signals the existence of conditions that could allow contamination to enter the distribution system. While under this advisory, all water should be brought to a rolling boil for at least a minute, then cooled, before using. Impacted customers were instructed to use boiled or bottled water for drinking, making ice, washing dishes, brushing teeth and food preparation.
