Action item 7.16
Government approval for consultation on draft policy, guideline, framework, Bill.
That appropriate modelling of the local and regional groundwater system must be undertaken before any production approvals are granted to ensure that there are no unacceptable impacts on groundwater quality and quantity. This modelling should be undertaken as part of a SREBA.
To be completed by end December 2022.
Action item update
The Department of Environment, Parks and Water Security in collaboration with the Commonwealth Government's Geological and Bioregional Assessment (GBA) of the Beetaloo Sub-basin has commenced modelling of the Cambrian Tindall Limestone aquifers.
The Water Quality and Quantity studies within the Strategic Regional Environmental and Baseline Assessment (SREBA) program will further develop the modelling and a detailed gap analysis of water-related information for the Beetaloo Basin has been completed. New water monitoring bores in poorly studied western parts of the basin were established during 2021 and drilling for additional new water monitoring bores to fill information gaps in other parts of the basin is currently underway and will continue through to 2022. An extensive array of existing bores were tested for water quality during 2021 and testing will continue through 2022.
Charles Darwin University has been contracted to undertake additional isotope analyses to further resolve groundwater connectivity questions.
