Residents in some parts of Southern California have been urged to boil drinking water amid concerns over E. coli contamination. Late on Thursday Pacific Time, local provider Californian American Water (CAW) issued an “Advisory to Boil Water” to customers in southwestern parts of San Diego County. The advisory comes after E. coli was detected in samples of drinking water, CAW said in a statement. Escherichia coli (E. coli) is a bacteria that normally lives in the intestines of healthy people and animals.
