Elimatta Coal: groundwater impact assessment

The Elimatta Coal project was a proposed open-cut coal mine located approximately 40 km south-west of Taroom, in Queensland. The project occurs within the Surat Basin and targets the Walloon Coal Measures. We were engaged to complete a groundwater impact assessment to form part of the Environmental Impact Statement (EIS).

The groundwater impact assessment involved the development of a groundwater monitoring plan and review of historic data in order to gain an in-depth understanding of the hydrogeological regime for development of the conceptual groundwater model. Based on this work, a numerical groundwater model was developed to simulate natural groundwater processes and replicate system stresses, in order to predict potential changes due to the project.

Elimatta Coal project: groundwater impact assessment




Field services, conceptual groundwater modelling, numerical groundwater modelling

Outcomes we delivered

Outcomes we delivered

The outcomes included:

  • quantification of groundwater take from the Great Artesian Basin water resource plan, for licensing purposes
  • predicted changes in water levels in the various aquifers
  • assessment of impacts on key receptors, including private landholder bores.

We were subsequently engaged to update the groundwater impact assessment to include cumulative impacts from emergent coal seam gas operations.
