Effective immediately, users of the City of Humboldt and South Humboldt Water Users Corporation are under a precautionary drinking water advisory.

The PDWA, put in place by the Water Security Agency says it's due to unplanned maintenance on the new storage reservoir and the potential contamination of water entering the system.

If ingesting the water from your tap, boil it for at least a minute, you should also do so if you are brushing teeth, washing fruits and vegetables or making ice cubes.

They urge you not to drink from water fountains either.

The advisory will be in effect until the water is deemed safe.
