The water authority said it routinely monitors and tests water in the area and that its treatment processes have not been impacted.

Officials said treated drinking water remains safe and that treatment adjustments will be made if needed to keep the water safe.

Authorities are warning people and pets to avoid swimming in or ingesting water near the affected area until the bloom clears.
