Sydney aquifer contamination widens to 12 times its present levels, warns study
Sydney water is not at risk from underground groundwater contamination due to climate change, new research says.
While Australia’s water resources minister, Steven Miles, said his country’s environment minister, Matt Canavan, had made a “very serious” admission in December, scientists in the United States and a separate study have warned an aquifer of 2.5 million hectares near Port Hedland may have become contaminated by contamination from climate change.
Dr Brian Deakin from US Geological Survey’s Western Australia division has been studying the water around Port Hedland for many years.
Mr Canavan visited WA earlier this month and met a number of scientists including one who helped create the 2014 report on climate change that set out a range of 우리카지노mitigation options and risks from the environmental impact of climate change in Australia.
“From our current understanding it may reach 10 times that, in terms of the potential for an aquifer to have gone astray.
“But in terms of our understanding of this aquifer and how it can get contaminated if it does, that’s obviously very, very important to have these information, so we’re really hoping we can make some progress.”
Dr Deakin said a combination of climate change and ocean acidification could produce groundwater that is far less acidic than normal.
“If we get over 12 times or so the pH would be far below where we would expect it to be at sea level,” he said.
“If you’re growing the plant food in that area you would expect there to be less organic matter that is absorbed through the aquifer but that could be an issue because organic matter will simply sink through the water and can lead to some very negative impacts of acidification.”
Climate change could make seawater rise
The scientists who made the report to the Ministry of Resource, Water and Communities said the worst would happen if sea levels rose in western Australia by between one and two metres during the next 20 years.
They found that the water could be contaminated further by sea-level rise through the melting of Antarctic ice or by the rise of large glaciers.
But there was little to suggest the climate change would cause that.
Dr Andrew Leiper of the Western Australian government told the ABC that the state
