Residents in eastern Escondido are urged to boil all tap water before drinking or cooking with it until further notice.
The city of Escondido Municipal Water Department issued a boil tap water advisory on Wednesday, stating that several recent test samples have revealed the presence of coliform bacteria.
Water department personnel have not been able to identify any reason or incident that would have caused the positive test results, according to the advisory.
Affected areas include those east of Bear Valley Parkway and Citrus, south of Mountain View Drive, north and west of San Pasqual and Cloverdale roads, and all residents living on Canyon Crest Drive, Mountain Crest Glen and Emerald Oaks Glen.
