Victorian Aquifer Framework: Salinity Distribution for the Lower Tertiary Aquifer

Victorian Aquifer Framework (VAF) Salinity Distribution - LTA_TDS is a geospatial dataset mapping salinity levels for Aquifer Number 111, the Lower Tertiary Aquifer. The salinity distributions reflect the beneficial use segments prescribed in the State Environment Protection Policy (Waters) (2018). It is published by the Department of Energy, Environment and Climate Action and was last updated on April 9, 2026.

Use Cases

• Map groundwater salinity concentrations based on the defined aquifer boundaries.
• Assess water quality compliance for beneficial use segments as defined by the State Environment Protection Policy.
• Model salinity distribution and trends within the Lower Tertiary Aquifer system.
• Support environmental impact assessments for projects affecting the specified aquifer.

Strengths

• Data is explicitly linked to a formal environmental policy framework (State Environment Protection Policy (Waters) 2018).
• Available in multiple geospatial file formats (TAB, MIF, GDB, SHP, etc.) 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 spatial resolution are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
