Victorian Aquifer Framework: Salinity Distribution for Lower Tertiary Basalts

The Victorian Aquifer Framework (VAF) Salinity Distribution dataset maps salinity for Aquifer 112, the Lower Tertiary Basalts. It is published by the Department of Energy, Environment and Climate Action under a CC-BY-4.0 license. The salinity distributions reflect beneficial use segments prescribed in the State Environment Protection Policy (Waters) from 2018.

Use Cases

• Assess groundwater salinity compliance based on segments defined in the State Environment Protection Policy.
• Model groundwater quality for the Lower Tertiary Basalts aquifer based on the salinity distribution.
• Support environmental impact assessments for projects intersecting Aquifer 112.
• Inform water resource planning and management based on aquifer-specific salinity data.

Strengths

• Data is explicitly linked to the 2018 State Environment Protection Policy (Waters), providing a regulatory context.
• Available in multiple geospatial file formats including SHP, GDB, and DWG for compatibility with various GIS tools.
• Published under a permissive CC-BY-4.0 license, allowing for reuse with attribution.

Limitations

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