SAN DIEGO -- San Diego County health officials issued a boil water order Thursday for an RV park in Ramona after total coliform bacteria was found in the drinking water system.

The notification is for the Western Horizons Ramona Canyon RV Resort, at 24340 state Highway 78, according to the San Diego County Department of Environmental Health.

Total coliform bacteria can come from soils and other sources in the environment and can indicate a problem with the water supply system.

The boil water orders will remain in effect until the distribution systems have been disinfected and additional samples confirm the absence of bacteria in the water supply, according to the DEH.
