Abstract
The Water Resources Division (WRD) of the Northern Territory Department of Environment, Parks and Water Security (DEPWS) completed groundwater drilling and pumping tests in the aquifers underlying the Sturt Plateau during the 2020 dry season and build-up. The main aims of the activities were to build upon the existing scientific understanding of the aquifers and establish long-term monitoring sites.
Groundwater drilling and pumping test activities focused on the Sturt Plateau area due to limited groundwater monitoring (Figure 1 1). There is also interest in improvement of the understanding of the sub-basalt sandstone aquifer that underlies the Wiso-Daly-Flora Cambrian Limestone Aquifer (CLA). This aquifer occurs at shallower depths in this region compared to the deeper Georgina-Daly-Roper CLA, hence may be more economical to use as a groundwater resource for future onshore gas development of the Beetaloo Sub-basin (Figure 1 1). The project is one of the first steps towards better defining the sandstone aquifer’s hydraulic properties, water quality, degree of connection to shallower aquifers, and establishing baseline monitoring.,
