Abstract
Summary Communities in the Anangu Pitjantjatjara Yankunytjatjara (APY) Lands of South Australia live in a remote and extrememly arid environment. To ensure continued access to sustainable groundwater resources, which these communities rely upon, we will conduct a geophysical survey consisting of complementary surface Nuclear Magnetic Resonance (NMR) and Time-Domain Electromagnetic (TEM) measurements to map local aquifers, quantify groundwater resources, and locate optimal sites for potential future wells. By pairing surface NMR and TEM measurements we take advantage of the unique ability of the NMR measurement to give unambiguous water detection, while exploiting the fast TEM measurements to map aquifer geometry over a large region entirely non-invasively. The project, funded through the Geoscientists without Borders Program of the Society of Exploration Geophysicists, aims to use geophysical tools to help address a critical water security problem facing several remote and underprivileged communities.
