Residents are being urged to steer clear of the ponds in two parks in Canterbury-Bankstown, after toxic blue-green algae was found.
Wiley Park and Maluga Passive Park at Birrong are among 25 locations throughout the state, where NSW Water has issued red alerts for toxic blue-green algae.
Mayor Khal Asfour said the blue-green algae has the potential to be dangerous to people and animals who come in contact with it.
“We have been told it can cause skin and eye irritation, as well as gastroenteritis if consumed,” he said.
“If a large amount is consumed, it can also cause liver and neurological damage.
“I strongly urge people to not undertake recreational activities at Wiley Park and Maluga Passive Park, where they may come into direct contact with the water in the ponds.
“It is also important people do not allow their pets to jump in or attempt to drink the water.”
Blue-green algae is common during warmer months and occurs naturally when the temperature of the water increases and there is low rainfall. It reproduces quickly in conditions where there is still or slow-flowing water, ample sunlight, high levels of nutrients, and where people feed birdlife like ducks.
“Algal blooms are reduced by significant rainfalls that flush the ponds, and cooler weather,” Mayor Asfour said.
“Unfortunately, there are no effective intervention treatment options. In fact, chemicals often make the problem worse.”
Council officers will continue to monitor the water quality at these sites.
