ITHACA, N.Y. –– Officials are alerting the public to a mysterious pink dye found flowing into a storm drain on Cayuga St. and out into Six Mile Creek –– advising that the substance is non-hazardous and authorities have already been made aware of the situation.

The substance was first noticed by NYSEG crews at around 7:30 a.m. Tuesday morning. Crews working on the the 500 block of S. Cayuga St. observed the unknown substance flowing into a storm drain and reported it to the Ithaca Fire Department.

The NYS Office of Fire Prevention and Control, who were in town doing a training with IFD, responded to the scene alongside firefighters.

IFD dispatched their hazardous materials team to test the substance and found it to be benign. Investigators believe the substance is a “tracer dye” used by workers at the site above looking for a leak in the pipes.

D.E.C., County and City Officials have all been made aware of the situation, and members of the public that see the pinkish water in the Six Mile Creek area do not need to report it further.

IFD reports that the color should dissipate with time.
