Groundwater polluting the Great Barrier Reef?

25 January 2024



Scientists have recently discovered that large flows of pollution are reaching the Great Barrier Reef after soaking into underground water. The new research claims that almost a third of dissolved inorganic nitrogen and two-thirds of dissolved inorganic phosphorus in the reef’s waters are coming from underground sources.

UN science experts have recently flagged concerns regarding the lack of sufficient progress in improving water quality. Furthermore, Dr Douglas Tait recently stated that the study “underscores the need for a strategic shift in management approaches”. There exists limited research into the contribution of groundwater as a route for nutrients to reach the reef, however, its contribution had until recently been considered minor.

The government has invested a significant sum of money into protecting the reef, as well as endorsing practical projects to improve the quality of water flowing to the reef. On a smaller scale, there is much that can be done to mitigate potential impacts of pollution. The continual monitoring & management of groundwater being one of the ways we can ensure improved water quality.
