MIAMI BEACH, Fla. -

A precautionary advisory to avoid contact with water has been updated to lift the ban from Biscayne Bay, the City of Miami Beach announced Thursday afternoon.

The city said, however, that Collins Canal, Indian Creek and Surprise Lake are still under the advisory.

Drinking water remains safe for use, authorities said.

Crews continue to work in the area of the broken wastewater line in the City Center/Convention Center area, between Meridian Avenue and Convention Center Drive.

The city says crews are conducting exploratory excavations in preparation for final repairs.

Authorities said the work performed left the system operational while additional repairs will be performed to the failed wastewater line.

The city said it will continue to work with environmental agencies to ensure the safety of surrounding waterways. Miami-Dade County Department of Environmental Resource Management and the Florida Department of Health will continue sampling the waters.
