Published on

The Groundwater and Storage interactions project arose out of a meeting on the shoulder of the Greenhouse Gas Technologies Conference in Amsterdam in 2010. It was decided to concentrate initially on the Australian Flagships projects. On 3 May 2011 Australian researchers and government agencies met and presented their work to date.

In these slides, Philip Denby, Government of Western Australia, Department of Water, presents on Groundwater and CCS

  21. 21. Great Artesian Basin Water Resources Assessment (GABWRA) • Joint project with Geoscience Australia and CSIRO • Detailed basin-scale investigation of water availability in the Great Artesian Basin. • Funded ($6.25M) by the Department of Sustainability, Environment, Water, Population and Communities (SEWPaC) and National Water Commission.3 May Groundwater and CCS Workshop

  24. 24. GA – GSQ groundwater surveys• Detailed analysis for gaps in the Surat and Bowen basins• Field measurements• Organics (including BTEX), trace metals• Isotopes (Cl-36, C-14, C-13, d2H, d18O)• Analysis of groundwater gases - composition and isotopes• Investigating tools to assess connectivity3 May Groundwater and CCS Workshop
  25. 25. Issues • Salinity in the GAB is fresh to brackish • Groundwater data coverage limited – esp. field parameters (e.g. Eh, pH), isotopes, trace metal and organics • Isotopes (water and gas) will be key for assessing connectivity • Risk of CO2 waters intersecting groundwater used for agriculture/potable supplies is higher in Australia than North America • Bore integrity3 May Groundwater and CCS Workshop
