Hydrogeology is defined as that branch of geology which deals with the study of underground water and the geological aspects of surface water. As a result of this study, the department can determine the location, extent, and depth of water-bearing geological features (aquifers) and the amount and quality of the water they contain.
The hydrogeology beneath a property can affect the use and enjoyment of the property in the following ways:
- the availability, and quality, of groundwater below the property
- the depth to the groundwater and the nature of the rock through which a bore would pass in order to reach it
- the type of geological formation(s) below the property
- impacts on the environment, other users, and the aquifer system caused by abstraction or contamination.
The general hydrogeology of the property can be reviewed by using the Hydrogeological Atlas on the department’s website. You should be aware that due to the broad, regional scale of the map the accuracy of the hydrogeological boundaries near different formations is low.
If more detail is required for the property of interest then an application should be made to the department for more data (see the Monitoring and Data section of the department’s website) or for more advice (contact the Water Resource Assessment Branch on (08) 6364 7600).
