The water supply has apparently been restored for residents of Castella in Northern Shasta County, but a boil-before-using order is in effect until further notice. Tap water for Shasta County Service Area #3 needs to be boiled or otherwise disinfected before being used for anything involving drinking, food, tooth-brushing or any similar use. The Castella water should be presumed to be contaminated with bacteria until it’s declared safe by water system personnel. Questions can be directed to the Department of Public Works at 225-5661.
