Severe infestations of blue-green algae in Sydney’s drinking water catchments have soared 800 per cent, according to an audit which warned climate change is putting the sensitive waterways under increasing threat from toxic blooms.The audit also called for an investigation into levels of pollution in Coxs River, which feeds into Warragamba Dam, Sydney’s main drinking water reservoir.
“If we had to treat poor quality water, it would require us to use more energy and more chemicals,” he said. “Costs to treat drinking water would increase, as would the greenhouse footprint and other environmental impacts.”can also reveal there are health concerns over the potential use of blue-green algae tainted water to grow crops in the Sydney basin.It was prepared by independent consultants for WaterNSW, the agency in charge of protecting the health of the catchments.
Further investigation was also needed into the rehabilitation of coal mines and the water losses and water quality impacts they caused, the audit found. There were 223 “red alerts” for severe blue-green algae outbreaks between 2016 and 2019, up from 23 in the previous audit period.Some strains of the algae are harmless but others produce hazardous toxins that can cause vomiting, liver and nerve damage, liver cancer and even death in humans and animals.between a toxin sometimes found in blue-green algae and motor neuron disease.
A WaterNSW spokesman said its comprehensive water quality monitoring program could detect blue-green algae, and respond with operational changes to avoid sourcing affected water.The spokesman added while climate change could pose a risk to long term water security, WaterNSW was working to develop "viable mitigation options".
A court blocked the mine’s extension in 2017 because of concerns about its effect on the catchment, but the NSW government overturned the decision.
KetanJ0 Such garbage. Manage the algae bloom and climate will take care of itself.
Not enough water . . . blame climate change Plenty of water . . . blame climate change Whatever happens, climate change narrative must be kept alive so billionaire developers get their tax subsidies for toxic ‘made in China’ wind and solar.
Now that that dams are full to capacity, the climate alarmists need a narrative. Did they mention that the present controlled release of surface water of the dams is bringing down the algae to acceptable levels?
The same people who not long ago said it won’t rain again. 😳
They’ve only been measuring blue green algae for 30 years. (Weather) But somehow this proves climate! 😂
Nestle love this kind of stuff
Oh no! Here we go again!
Maybe all the debris from the bushfires?
And people keep voting for it. You reap what you sow...
Sydney Water Dept doing what they do best. Sweet fuck all.
They don't seem to have a problem in Queensland. Why would it be any worse in Sydney?
Bulls**t
UnswWater GladysB
Too much stagnant water...
Great. Just great
Another impact from the bushfire crisis with run off after heavy rains?
Like the 1998 Sydney water crisis. Huge panic, everyone had to boil their water or bottled water. Cost millions. Read the last line of this article.
Climate change is a hoax perpetrated by the globalists.
This was the issue back in 2014 as well. Apparently, they don't care enough to change it.
