Sydney aquifer contamination widens in 2013

If the water table in New South Wales was falling along with the city’s population by 2014, it would raise questions about its ability to cope.
While that water table is likely to be more stable, the state’s water authorities are concerned that it has become less predictable.
According to the latest state water-system estimates, the water table has dropped between about 18 inches (49 cm) to 8 inches (20 cm) lower since 2013.
“In terms of stability, we think the water table continues to decline because you’re continuing to produce excess resources from fossil fuel extraction,” NSW Water CEO Steve Taylor told Fairfax Media.
“New South Wales is a coal country and we continue to do all we can to keep our water systemjarvees.coms clean because there’s not a lot of water 바카라사이트remaining, especially after a massive snow event.”
Taylor said the water table was about two-thirds of what it was before 2013 but expected it to return before 2015.
“We do expect we will see some drops from time to time but that’s the nature of the business we’re dealing with,” he said.
The state’s electricity-grid operator PSC Energy said it had taken steps to make sure water supplies were safe, and expected them to return to pre-fall levels by the end of the year.
But if water levels continued to drop, the system had to adjust power to offset this, Taylor said.
“A very low water level means there is a decrease in power generation as well and, because of this, it’s a time when people are being forced to turn down the heat,” he said.
The state’s energy-storage system was also at risk due to the water table dropping.
“What we can say is that power generation is definitely being impacted because we’ve seen reduced power generation capacity that have to be replaced or repowered to get the grid back up and running,” Taylor said.
According to PSC’s annual report on water, the state’s electricity generation is expected to recover from the 2013 drop to about 40 per cent of what it was before the event, but that will rise to 70 per cent once the grid recovers, he said.
Energy storage is also at risk because if it falls, transmission can no longer provide enough power to cover the shortfall, so transjarvees.commission can’t meet the demand.
