Contaminated water was found in the KQ Ranch water system in Julian, prompting a Boil Water Order and Public Notification, effective immediately on Friday.
According to the County of San Diego, Department of Environmental Health (DEH), E.coli and total coliform bacteria was found in the drinking water system--indicating the water may be contaminated with human or animal wastes.
Symptoms include cramps, nausea, headaches or diarrhea.
DEH said E.coli can be especially risky for infants, young children, the elderly and anyone with a compromised immune system.
The Boil Water Order will remain in effect until lab results indicate no presence of the bacteria.
The water system is located at 449 KQ Ranch Road in Julian and serves the KQ Ranch Campground.
