DESCRIPTION
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, Dr Monica Campi, GeoScience Victoria, Presents on Victorian CCS – Groundwater issues
