Water is a valuable commodity in the Anangu Pitjantjatjara Yankunytjatjara (APY) Lands, which has traditionally been sourced from palaeovalley sands, calcrete, and alluvial and aeolian sediments, as well as from the onlapping sediments of the Officer Basin. A recent commissioned study has attempted to recognise structural or weathering features within the outcrop, and in shallowly buried bedrock areas around some of the main communities in the APY Lands, that may host groundwater aquifers. This work used a range of existing datasets, such as pre-existing geological data, aeromagnetic data, airphoto orthoimages, digital elevation models, Landsat imagery, and earthquake data to find potential new groundwater drilling targets. No new data was collected, nor was there any ground-truthing. The targets focus on hard rock areas that may have enhanced porosity and permeability. These include areas of fractured rock, recognisable on orthoimages, which could represent breccia zones or faults, and areas where several lineaments intersect. Also of interest are areas where breaks in outcrop coincided with aeromagnetic low lineaments, suggesting the presence of eroded faults covered by a veneer of Cenozoic sediments.
