Hydrogeological maps

This section includes a series of hydrogeological maps that depict the subsurface geological material in which groundwater occurs. They help hydrogeologists to understand the movement of groundwater in an area.

The Hydrogeological Map Series of New South Wales (1986-1988) was compiled and published by the Hydrogeological Unit of Department of Water Resources, New South Wales (a previous iteration of the Department of Planning, Industry and Environment - Water). The maps in this series are provided for viewing and/or download in the links below.

Groundwater vulnerability maps

Groundwater vulnerability maps show the vulnerability (or level of risk) of aquifers to contamination relating to physical characteristics of the location. These groundwater vulnerability maps are located within the groundwater quality page of our website.
