Blue Green Alage alert for Greaves Road Retarding Basin, Berwick

​Melbourne Water is advising people to avoid contact with water at the Greaves Road retarding basin in Berwick, following the detection of blue-green algae. 

Signs have been erected at the retarding basin, located in the Berwick Springs estate, in order to alert residents and visitors to the issue as a precaution.

Melbourne Water Manager Regional Services (South East), John Woodland said there were many forms of blue-green algae and the species currently present could be harmful to animals or humans. 

"It’s important that people avoid contact with the water and make sure that it does not come into contact with their skin or eyes," he said. 

"Pet owners are advised to take similar precautions and keep their animals from entering the water or from drinking it."

"Melbourne Water will sample the water regularly and keep a close watch on the problem. Signs have been erected around the lake to warn people of the potential hazards."

Melbourne Water is working with City of Casey to manage the algae bloom in line with Victorian Government guidelines, and will continue to monitor the site.

Blue-green algae occurs naturally in waterways and forms blooms during hot weather, periods of drought or low flow, or where there is an accumulation of nutrients in waterways or water bodies.
