At least 18 households in Mountain View are expected to remain under a boil water notice as the city works to disinfect a pipeline this week. Test results continue to show coliform bacteria in a pipeline serving Drucilla Drive and Carla Court, according to the city. On Wednesday, the city will begin the process for a “super chlorination” of the pipeline. … “This ‘super chlorination’ process is intended to address the presence of low levels of coliform bacteria, which appear to be concentrated in the water line serving homes on Drucilla Drive and Carla Court,” the city said in an update Monday night. … The city shut off water service to 67 households on April 24 after a cement slurry mix came into contact with a water main during a pipe replacement project near Bonita Avenue and Cuesta Drive.
