Australian Groundwater Resources by Aquifer and Salinity Class

Five groundwater quality classes differentiated by salinity levels and yield rates. The data shows only one aquifer at any point, typically Upper Tertiary sand or limestone aquifers most developed or likely to be developed. It is provided by the Department of Energy, Environment and Climate Action and was last updated on 2026-04-09.

Use Cases

• Map groundwater salinity classes based on the five defined quality levels.
• Assess aquifer yield potential based on the differentiated yield rates.
• Identify development-ready aquifers based on the focus on Upper Tertiary sand or limestone formations.

Strengths

• Data defines five distinct groundwater quality classes.
• Focuses on Upper Tertiary sand or limestone aquifers, which are the most developed or likely to be developed.
• Available in multiple geospatial formats including GDB, SHP, and WFS.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au.
