Tap water is now safe to drink in areas served by all nine water systems where damage from the firestorms in Altadena and Pacific Palisades had prompted “do not drink” notices, state regulators said Friday. The last water utility with such a notice, the Las Flores Water Co. in Altadena, was cleared to resume delivering drinking water and lifted its “do not drink” and “do not boil” advisory on Friday, four months after the notice was issued. Las Flores has recommended to customers that when they resume using water, they take various steps to flush the household system, including running all the faucets for at least five minutes before using. Officials from the State Water Resources Control Board said they have been working with utilities to help assess damage, test for potential contamination and ensure it’s safe to resume water service.
