“…Regional groundwater movement in the aquifers is towards the southern, south-western, western and northern margins, where artesian springs provide natural discharges (Figures 1, 2 & 4;Habermehl, 2020;Habermehl & Lau, 1997;Keppel et al, 2013;Love et al, 2013;Smerdon et al, 2012a,b). Residence or travel times of artesian groundwater range from almost recent in the recharge areas to more than one million years near the centre of the GAB (Habermehl, 2020).…”

The area receives relatively high rainfall, whereas the western margin of the basin in the arid centre of the continent receives minor rainfall and thus little recharge (Keppel et al, 2013).…”

The Great Artesian Basin (GAB) is a regional groundwater system consisting of aquifers and confining beds within the sedimentary Eromanga, Surat and Carpentaria Basins. They underlie arid to semi-arid regions across 1.7 million km?, or one-fifth of the Australian continent. Artesian springs of the GAB are naturally occurring outlets of groundwater from the confined aquifers. Springs predominantly occur near the eastern recharge margins and the south-western and western discharge margins of the GAB. These zones of natural groundwater discharge represent areas of permanent water, with widely recognised cultural, spiritual and subsistence importance to Indigenous people for tens of thousands of years. The unique hydrogeological environments -discharge, hydrochemistry and substrate -support a range of endemic flora and fauna protected under the EPBC Act (1999). Springs have formed in many areas across the GAB; however, the largest concentrations occur near the south-western margins of the basin. Supporting these flowing artesian springs is a multi-layered aquifer system, comprising Jurassicto Cretaceous-age sandstones and siltstone, and confining beds of mudstones. Hydrogeological, hydrochemical and isotope hydrology studies show that most artesian springs and flowing water bores in the GAB derive their water from the main Jurassic-Lower Cretaceous Cadna-owie Formation -Hooray Sandstone aquifer and its equivalents. Focusing on springs in South Australia, this paper provides a summary of the hydrogeology of the GAB, including zones of recharge and regional groundwater flow directions, with a major focus on summarising understanding of the occurrence and formation of springs.

This study examined the sustainability of CO 2 -rich water by analyzing the water level and water quality change pattern with the amount of its use in Angseong area, Chungju. The origin and supply of CO 2 component were discussed in consideration of 87 Sr/ 86 Sr ratio, occurrence of CO 2 -rich fluid inclusions in nearby W-Mo deposits and other surrounding geological characteristics. According to the data from 1986 to 2017, the depth of the water level of CO 2 -rich water was significantly lowered in the late period (2009)(2010)(2011)(2012)(2013)(2014)(2015) than in the early period (1986)(1987)(1988)(1989)(1990)(1991)(1992) of the development of hot spa wells, and the optimal yields for pumping tests also showed a tendency to gradual decrease. Concentrations of CO 2 component also decreased continuously in the later stages compared to the early stages of development, but it has been stable since 2012. It is inferred that the geological environment related to forming W-Mo quartz vein deposits (0.5×1.5×several km) around the study area are largely involved in the origin and supply of CO 2 component, and the supply of CO 2 component is not infinitely supplied from deep current magma activity. Rather, since it is finitely supplied from a restricted subsurface region formed in the past geological period, it is necessary to efficiently control its use in order to maintain the sustainability of CO 2 -rich water in the study area.Keywords: CO 2 -rich water, Chungju Angseong area, water level and quality variations, CO 2 source, CO 2 -rich zone

The Freeling Spring primary spring tail is located in a lineament perpendicular to the Kingston Fault and is likely composed of a number of small springs discharging along the fault orientation as it occurs near the fault intersection (Karlstrom et al 2013;Keppel et al 2019). The spring tail for Freeling Spring is smaller and oriented to the east of the spring along the cross-section line A-A ′ (Figs.…”

Evidence for groundwater mixing at Freeling Spring Group, South Australia

et al. 2019

Water sampling at springs that are a part of the Freeling Spring Group, South Australia, was used along with electrical resistivity imaging (ERI) data to evaluate the sources and pathways for groundwater to the springs and to find evidence of mixing between the Great Artesian Basin (GAB) aquifer system (Algebuckina Sandstone, Cadna-owie Formation and lateral equivalents) and waters from the adjacent mountain block basement (MB) aquifer. Five springs and a well were used to evaluate spring chemistry; multi-electrode resistivity data were collected along three orientations over the Freeling Spring site. The resistivity data indicate three independent electrically conductive curvilinear features connected to the spring. These features are evidence of mixing at the spring vent similar to what would be predicted from traditional hydraulic flownets. The chemistry of the spring water samples indicates that the water emanating from the Freeling Spring Group is a mixture of waters from both the GAB and the MB aquifers, supporting the geophysical evidence. The data suggest mixing occurs along a fracture in the body of the MB and porous media flow in the GAB beds, but the system is dominated by the GAB flow, which provides approximately 90% of the discharge.
