This analysis will determine groundwater age in NSW aquifers.

Project overview

This analysis investigated groundwater age (time since recharge) in New South Wales (NSW) aquifers. The research used groundwater stable and decaying isotope data and hydrochemistry results.

The project used samples already collected by the Australian Nuclear Science and Technology Organisation (ANSTO).

This provides information about groundwater flow, aquifer interconnectivity and aquifer replenishment rates. 

This research improved the understanding of the renewability of the groundwater resources.

Goals of the assessment

This assessment:

  • investigated the use of a spatial geographic information system (GIS)
  • assessed existing hydrological and hydrogeological data
  • developed more detailed maps of all of NSW, where data is available.

These maps estimate the scale of underground storage capacity. The maps also estimate how these storages are distributed. The research looks at where opportunities for managed aquifer recharge (MAR) projects are able to support primary industries.
