The water in Careening Cove at Milson Park, Kirribilli, is still bright green a day after a substance was discovered leaking from a stormwater drain. Authorities said there was no indication the substance is toxic, and it is most likely a fluorescein dye that could have entered the drain ‘from thousands of areas’. Locals were left shocked by the appearance of the substance, with one telling a news outlet the water resembled ‘green cordial’. Water expert and professor of environmental engineering at the University of Sydney, Stuart Khan, said fluorescein is used as a flow tracer, to determine whether pipes might leak or where they might flow to. ‘Even if somebody was doing a legitimate task … they’ve used way too much of it,’ Prof Khan said. ‘It’s a massive amount. It’s probably a whole bucket full of fluorescein dye’
