Victorian Aquifer Framework: Salinity Distribution for the Lower Mid-Tertiary Aquifer

A 2026 dataset from the Department of Energy, Environment and Climate Action details salinity distribution within the Lower Mid-Tertiary Aquifer (Aquifer 109) in Victoria, Australia. It reflects beneficial use segments prescribed by the State Environment Protection Policy (Waters) from 2018. The data is provided in multiple geospatial formats including SHP and GDB.

Use Cases

• Map groundwater salinity levels based on the defined aquifer boundaries.
• Assess water quality compliance based on beneficial use segments referenced in the State Environment Protection Policy.
• Model contaminant transport or aquifer health for the specific Lower Mid-Tertiary Aquifer layer.
• Support environmental impact assessments for projects interacting with the aquifer.

Strengths

• Data is explicitly linked to the 2018 State Environment Protection Policy (Waters), providing a regulatory context.
• Available in multiple standard geospatial formats (SHP, GDB, TAB, etc.) for interoperability.
• Last updated in April 2026, suggesting recent maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial extent are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
