The State Water Resources Control Board on Thursday afternoon issued a Boil Water Advisory for the Silver Strand area of Coronado and Imperial Beach.

However, the problem did not come from sewage flowing from Tijuana, according to Dave Gibson, who leads the San Diego Regional Water Quality Control Board.

Gibson told The Coronado News that it’s most likely a water systems problem from an unspecified pipeline issue.

“It’s not a border issue. It’s not ocean water,” Gibson said.

The shorelines of Coronado and Imperial Beach have consistently been closed this year and in 2022 because of tens of millions of gallons of raw sewage flowing from Tijuana. A Coronado News investigation earlier this year found decades of broken promises by U.S. and Mexican leaders have contributed to unsanitary ocean water that has made local residents, U.S. Border Patrol agents and Navy SEALs extremely ill.

What the warning says

The San Diego County Emergency Site issued the warning around 1 p.m.

Affected customers will be contacted directly by Cal American Water Company with additional information.  

An earlier release said the drinking water system has tested present for E.Coli bacteria.

The presence of E.Coli bacteria indicates that the water may be contaminated with human or animal waste. Health effects can include diarrhea, cramps, nausea, headaches or other symptoms. E.Coli may pose a special health risk for infants, young children, some elderly and people with severely compromised immune systems.

What to do

The county emergency site said:

• The water is not safe to drink.

• Boil all water for 3 minutes.

• Let the water cool before you use it.

• Use of bottled water encouraged for drinking, brushing teeth and food preparation until further notice.

• Boiling water kills bacteria and other organisms in the water.

The Boil Water Order was issued to ensure all water used is free from bacterial contamination. The Boil Water Order will remain in effect until laboratory results confirm the absence of bacteria in the water supply.
