Authorities are still investigating the source and residual impact of contamination that turned a popular section of an inner city creek a bright shade of purple earlier this week.
Iris Firat, a nearby resident, said she was “very, very shocked” to see the discolouration of the Duck River near the Auburn Botanic Gardens on Thursday.
“It’s usually a very murky river,” the student said. “I’ve never seen the river any other colour than brown.”
“We thought it was the sun playing with our eyes but when we moved to the shade, it was just as bad,” Ms Firat said.
