and treated water from the Leslie O. Carter Water Treatment Plant through the three-million-gallon water tank, or 3M, that is also on Avenue S. In late October, the State Water Resources Control Board, Division of Drinking Water asked PWD to remove the baffle curtains after debris that included pieces of the curtain was found in water being flushed from a transmis- sion main. Baffle curtains in the 6M, which is where treated water is stored before distribution, increase contact time for chlorine-treated water by creating a longer flow path within the tank, improving water treatment per- formance. The 6M will operate with additional controls to get the same performance until new baffle curtains are installed. According to LaMoreaux, the baffle curtains were from the late 1990s. The curtain material is Hypalon, which does not dissolve and is safe to be in contact with drinking water, per the National Science Foundation. As required by the state, PWD publishes an annual Consumer Confidence Report that provides detailed informa- tion about its water quality. In 2022, PWD completed more than 18,000 tests for 80 regulated contaminants. The report is available in English and Spanish on the PWD website at www.palmdalewater.org.
