Callide Power Station

Callide PFAS monitoring

CS Energy is conducting a voluntary investigation into the potential environmental impact of our historical use of PFAS at Callide Power Station.

Callide's use of PFAS was infrequent and in small quantities for training, testing and emergency response purposes. We removed firefighting foams containing non-compliant levels of PFAS in 2019 as part of a Queensland Government policy to phase out their use.

Monitoring program

CS Energy is working with an independent environmental testing firm to understand the impact of our historical PFAS use at Callide Power Station. We are also working closely with the Department of Environment and Science and Queensland Health, and following their advice.

The health of the community and our employees is CS Energy’s key priority and will guide our actions throughout the monitoring program. We are speaking directly with affected landholders and proactively updating the broader Biloela community and our employees.

Test results

31/03/2021 - Results from testing on landholder properties in zone 1

CS Energy has divided the sampling area near Callide Power Station into four geographic zones so that the testing can be carried out as efficiently as possible. We’ve been receiving the results in batches and we how have all the results for zone 1.

In zone 1:

  • Samples were collected from 21 landholders’ properties in the area downstream along Callide Creek to just past the Linkes Road creek crossing.
  • Seven landholders had at least one sample point over drinking water guidelines, with four of those landholders using it for drinking water. CS Energy has organised an alternative drinking water supply for these four landholders.
  • The remaining 14 landholder properties returned results under the drinking water guidelines.

CS Energy has provided each landholder with their results, including their own laboratory report, relevant advice from Queensland Health and the Department of Environment and Science, and information from the Department of Agriculture and Fisheries about using bore water for irrigating crops and for livestock.

Next steps

Further work is required to better understand the variable nature of the results and the influence of factors such as bore depth, age and volume of use; aquifer connectivity; and interaction between surface water and groundwater.

Testing is still under way for properties in the other sampling zones. As we continue to receive results for each zone we will periodically update the map on our website. We expect to release the results for zones 2 and 3 in May.

Our technical experts are also developing a longer term PFAS monitoring and management program in consultation with the Department of Environment and Science.

01/03/2021 - Sampling underway on landholder properties

In February 2021 we sampled on private landholder property in same section of Callide Creek as our January sampling program. We also did some extra sampling further downstream of Linkes Road at the request of some landholders.

The results are coming through in batches over February and March. Early results have shown a mix of PFAS levels above and below drinking water guidelines. Once we have all of the results, we’ll provide an update on the findings on this web page.

Our first priority is to talk through individual results with each landholder and provide them with their own lab report and the relevant advice from Queensland Health and the Department of Environment and Science.

In the meantime, we are continuing with our sampling program and will broaden the testing area to include properties between the Linkes Road creek crossing and the Dawson Highway.

22/02/2021 - Banana Shire Council tests of Biloela town water 

Following CS Energy's detection of PFAS in some locations near Callide Power Station, the Banana Shire Council tested the Biloela town water supply.

The results of Council's tests found that the Biloela water supply is safe to drink. Read the Council's update on their Facebook page.

08/02/2021 - Initial findings from sampling in January 2021

In January 2021 CS Energy's independent environmental testing firm took samples on site, and off site in the area adjacent to the power station.

Samples were taken adjacent to the power station and various locations along Callide Creek between the station and approximately four kilometres downstream to the Linkes Road creek crossing. None of the sample sites were on private property.

  • The tests found that at locations within and outside our site, there were levels of PFAS detected that were higher than the government guidelines for drinking water and species protection.
  • While some results were above the government guidelines, they were significantly lower than at other sites in Queensland that had PFAS in their groundwater.
  • We are working with the Department of Environment and Science (DES) and Queensland Health on these results.
  • DES and Queensland Health have identified one location about 4km downstream (near Linkes Road) as the priority public health focus area given its proximity to private property and distance from the power station.
  • The other locations that were above guidelines are either on, or very close to the power station site, and in the predicted flow path of PFAS.

Going forward, we'll be doing more monitoring and testing of water samples from the surrounding catchment. Over coming weeks and months we’ll be sampling on and off our site, and working with potentially affected landholders to test their bores they use for domestic purposes.
