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

Upper Hunter River Valley groundwater chemistry data from the Australian Ocean Data Network, last updated 2026-06-23. The description details chemical processes like silicate dissolution and ion exchange influencing water in Triassic, Carboniferous, and Permian rock aquifers. It discusses solute distributions and mineral disequilibrium indices for calcite, dolomite, and dawsonite.

Use Cases

• Modeling groundwater solute transport based on described silicate and carbonate dissolution/precipitation reactions.
• Analyzing hydrochemical facies and aquifer connectivity based on described regional recharge and transmission zones.
• Studying the influence of Permian marine salts on groundwater salinity via oxidation of sulphides and molecular diffusion.
• Investigating mineral saturation states using disequilibrium indices for calcite, dolomite, and dawsonite mentioned in the description.

Strengths

• Detailed geochemical process description covering multiple rock formations and aquifers.
• Specific mention of ion distributions (e.g., Ca2+, SiO2, HCO3) approaching log-normal patterns.
• Identifies key geological units (e.g., Wollombi Coal Measures, Greta Coal Measures) influencing water chemistry.

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, focusing solely on the Upper Hunter River Valley.
