Hydrogeochemistry of the Upper Hunter River Valley Groundwater in New South Wales

Geoscience Australia Data published a dataset on the chemistry of groundwater in the upper Hunter River valley of New South Wales. The description details the influence of geological formations and chemical processes like silicate dissolution and ion exchange on water composition. The data was last updated on 2026-04-30.

Use Cases

• Modeling groundwater contamination sources based on described processes like sulphide oxidation and molecular diffusion of connate salts.
• Analyzing mineral saturation and precipitation trends using disequilibrium indices for calcite, dolomite, and dawsonite mentioned in the description.
• Mapping regional hydrochemical facies based on the described stability fields of kaolinite and Ca-montmorillonite.
• Studying the distribution of saline water linked to specific Permian rock groups like the Greta Coal Measures and Maitland Group.

Strengths

• Detailed scientific description of geological and chemical processes influencing groundwater.
• Specific mention of key geological formations and aquifers, such as the Wollombi Coal Measures and Hunter River floodplain.
• Analysis includes disequilibrium indices for multiple carbonate and sulphate minerals.

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 the specific study area in New South Wales.
