Residents in a Peninsula suburb could be without water until at least midweek after an active drinking water line became contaminated during maintenance work. The problems started Friday in the Mountain View neighborhood of Cuesta Park when a contractor was working on a water replacement project, the city said on its website. As the contractor was attempting to fill an old pipe with cement near Bonita Avenue and Cuesta Drive, cement slurry, a liquid mix of cement, water and other chemicals, accidentally spilled into an active main providing drinking water. … Though city officials initially told residents that the water could be back by Monday, it determined that further repairs are needed after drinking water samples taken from the area came back positive for bacteria.
