"San Diego Area Residents Urged to Boil Water Amid E. coli Contamination Concerns"

Some residents in the San Diego area, including Imperial Beach, Coronado, San Diego, and Chula Vista, have been advised to boil their tap water and use bottled water for drinking and cooking due to the detection of E. coli in the drinking water. The public utility company, California American Water, expects to resolve the issue within 48 to 72 hours. The source of contamination is still unknown, but heavy rain and flooding from Hurricane Hilary may have contributed. Schools in the affected areas have closed as a precaution, and residents can pick up bottled water from the water company's operation center. E. coli infections can cause severe symptoms, especially in vulnerable populations.
