BOTANY Bay’s Foreshore Beach has been closed to swimming and fishing because of a 1km square bright orange plume of unknown origin.

The NSW Environment Protection Authority is investigating the source but so far their tests have shown that while high in iron mysterious plume is not toxic.

There is an insignificant amount of algae associated with it according to the EPA and containment with booms is not possible because it extends too deep into the water for them to be effective.

Sydney Ports closed Foreshore beach to swimming and fishing on Monday as a precaution.

The source of a bright orange plume in Botany Bay is still a mystery after early tests by the NSW Environmental Protection Authority.

People walking on Foreshore Beach in south Sydney noticed about a square kilometre of ocean coloured bright orange on Monday afternoon.

“I saw this orange and thought it must be that rain we had,” Roger Pearce said.

“But I’m looking at the shells on the beach and they’re bleached orange.”

Walking back along the shore, Mr Pearce said security guards told him that he had to get off the sand. But he returned on Tuesday afternoon and found the water still stained the unusual colour.

The Authority has tested the plume and the preliminary results show that while it is high in iron, it is not toxic.

It does not yet know where the plume comes from, but it might be from natural causes.

An “insignificant” amount of algae is associated with the orange plume, but is not the cause of the colour, the Authority said.

The Authority will continue to monitor the water.
