One advisory was issued on Nov. 1 for western Biscayne Bay, from the shoreline east to Intercoastal Coastal Waterway between the NE 67th St and Lake Road/NE 50th St.

The recent heavy rains caused a sewer pump station to overload.

The advisory area also included the shoreline among Morningside Park located between Lake Road and NE 55th St. and American Legion Park located between NE 64th and NE 67th streets.

On November 3, another advisory was also issued for the waters and shoreline off of Virginia Key Beach. Officials say a power interruption at the Virginia Key plant pumps to malfunction and discharge treated wastewater into the bay.

Swimmers were urged to avoid contact with surface waters in the area.

The Miami-Dade County Permitting, Environment and Regulatory Affairs Department conducted tests to determine when it is safe to swim in the water.
