Green liquid oozing out of the sewers in New York City?Henri Lumière

As strange as it sounds, that's what one passerby was able to capture and post on social media.

"So there’s literal green sludge bubbling up from the ground next to World Trade Center right now," Dan Pontelo wrote in a post on X.

While Pontelo and others may have been concerned, the florescent water is nothing to be worried about.

"Can anybody explain this or are we just living in full blown Gotham rn," Pontelo wrote in a follow up post.

Others commented that it was reminiscent of the Teenage Mutant Ninja Turtles.

Unfortunately, New York City has not shifted into a parallel universe and the green ooze isn't giving anyone superpowers any time soon.

In fact, it's just dye.

According to a disclaimer on the post, plumbers sometimes use dye to trace a leak or figure out what type of sewer system a facility may have.

In fact, this type of dye tracing can even help scientists "visualize how water moves from one place to another," the National Park Service said.

This isn't the first time residents have spotted the green dye in the city. In March, a X user posted an image of the green liquid in a subway station in Brooklyn.

Despite the disclaimer, Pontelo joked that he's still not convinced it's only dye.

"Contrary to the community note, I think the sludge is radioactive ooze. Source? Divine intuition," he wrote.
