Video shows green liquid being poured onto the floor of Miami International Airport on July 4, covering the tiles in fluorescent puddles.
According to MIA, the lime green leak in Concourse G of the airport was caused by a ruptured pipe.
Authorities initially said the mysterious fluid was glycol, but later said it was actually “water from the air conditioning system with a green dye in it, so if there is ever a leak, it can be traced back to the source. Totally harmless,” said Greg Chin, communications director for the Miami-Dade Aviation Department.
The airport has not indicated that this has caused any delays, which is positive, as the TSA expects to check a record number of people this July 4 weekend.
“The valve feeding the pipe has been closed to stop the leak and work is now underway to clean it up,” the airport said in a statement.
Part of the area was cordoned off with yellow caution tape so travelers could take photos and videos.
“We would like to thank our passengers in Concourse G for their patience and understanding,” authorities said.
