"Polluted runoff is still smothering the Great Barrier Reef, our first national
assessment of water quality trends in Australian rivers has revealed. The
problem on the reef is getting worse, not better, despite efforts to improve
farming practices and billions of dollars committed by governments to
water-quality improvements.
But in good news, there are signs of improvement in the Murray-Darling Basin,
where less salt, sediment and phosphorous were detected in the water.
Our latest research quantifies, for the first time, how water quality in
Australian rivers has changed over the past two decades. Around half our 287
monitoring sites experienced significant changes in water quality between 2000
and 2019 on every measure we analysed. But the results for the reef and the
basin stood out.
In particular, freshwater flows into the Great Barrier Reef lagoon contained
increasing levels of sediment and phosphorous. If the trend continues, we have
serious concerns for the health of the Great Barrier Reef and the tourist
industry it supports."
