California American Water Issues Boil Water Notice for Customers in Its San Diego District

California American Water today issued an “Advisory to Boil Water” for customers that reside in the city of Imperil Beach, Coronado customers (south of Fiddlers Cove) and customers in portions of San Diego and Chula Vista due to positive E. Coli results found in the drinking water. The California Division of Drinking Water in conjunction with California American Water, is advising impacted California American Water customers that reside in the above cities to use boiled tap water or bottled water for drinking and cooking purposes as a safety precaution.

California American Water customers in Imperial Beach and Coronado (south of Fiddlers Cove) are advised to not drink water without boiling it first. The California Division of Drinking Water recommends bringing all water to a boil, let it boil for three (3) minutes, and let it cool before using, or use bottled water. Boiled or bottled water should be used for drinking and food preparation until further notice. Boiling kills bacteria and other organisms in the water. This is the preferred method to assure that the water is safe to drink. Alternatively, you may add eight drops of unscented, household bleach to one gallon of water and let sit for 30 minutes.

California American Water customers are also asked to immediately discontinue any non-essential water usage. This includes all outdoor irrigation.

If customers have any questions, they may call California American Water’s customer service center at 888-237-1333. For updated information, customers can visit California American Water’s website at, under the Alerts Notifications section.

Please be advised that the company is doing all it can to make sure water is of the highest quality and anticipate resolving the problem within 24-48 hours. California American Water will provide information as to when the advisory is lifted.
