Are coal mines silently impacting the Great Barrier Reef's lifeline? As floodwaters recede after ex-Tropical Cyclone Koji, a critical issue is surfacing in Central Queensland. Over two dozen coal mines have been releasing water into the Fitzroy Basin, the primary water source for the magnificent Great Barrier Reef. While these releases are permitted under strict regulations, a local conservation group is raising serious concerns about the public's ability to truly understand the scope and composition of these discharges.
Coral Rowston, director of Environmental Advocacy in Central Queensland, highlights the sheer magnitude of the situation. "The volume of water they're pumping out of their contaminated holding dams and the like is huge," she states. The Fitzroy Basin is home to 52 coal mines, each operating under specific environmental guidelines that dictate when and how much water they can release. This information is theoretically updated in real-time, offering a snapshot of ongoing operations.
But here's where it gets controversial... Dr. Rowston points out a significant hurdle: the difficulty in tracking these releases effectively. She's advocating for the regular publication of the "28-day report". This crucial document, compiled by each mine, details water releases at various points along the catchment. "More transparency will help us understand the cumulative impacts… to make sure that water being released isn't impacting our urban and agricultural water supplies," she emphasizes. The concern is that without this detailed, readily available information, it's challenging to assess the combined effect of these discharges on both the environment and our essential water resources.
And this is the part most people miss... While the Department of Environment, Tourism, Science and Innovation's website does show that 55 water releases occurred from central Queensland coal mines last month, during a period of significant flooding in areas like Clermont and Rockhampton, obtaining a clear, timely picture is still a challenge. Dr. Rowston observed that on January 15th alone, 19 mines released water from 26 sites at a staggering combined rate of well over 123,000 litres per second. However, the absence of the 28-day report means it's difficult to ascertain the total volume of water released, as well as the precise quantity and types of chemicals present.
Currently, details about the basin's health are summarized annually in the Fitzroy Partnership for River Health's "report card." The 28-day reports themselves are accessible, but only upon request through the public register portal, with response times potentially stretching up to 60 days. This delay can be problematic for timely environmental monitoring.
The Queensland Environment Department has stated that the January releases adhered to regulations but did not provide a total water release figure. They did, however, note that eight releases on January 30th constituted roughly 0.006 per cent of the basin's total water flow, a vast area spanning over 140,000 square kilometres with 20,000 kilometres of waterways.
A closer look at the high flow period releases: Coal mines are permitted to release water during periods of high river flow. This practice serves a dual purpose: to prevent on-site flooding and to ensure that the discharged water is sufficiently diluted, thereby minimizing potential environmental harm. This approach was established following a state government pilot program conducted during the wet seasons from 2012 to 2016. The findings from this pilot indicated no discernible negative impact on water quality concerning ecosystem health, livestock irrigation, or domestic use, according to the department. Before any release is approved, the department rigorously assesses potential impacts on water quality and the environment, ensuring compliance with water rate and quality limits.
A spokesperson for the Queensland Resources Council affirmed that water releases are "heavily regulated, monitored and enforced" and that companies are committed to their environmental responsibilities.
What are your thoughts? Is the current level of transparency sufficient to protect vital waterways like the Fitzroy Basin and the Great Barrier Reef? Should the 28-day reports be automatically and publicly published in real-time? Share your opinions in the comments below – we'd love to hear your perspective!
