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

A dataset describing the chemical composition of groundwater in the upper Hunter River valley of New South Wales. The data likely contains concentrations of ions like Ca2+, SiO2, HCO3-, Cl-, Na+, SO4^2-, and Mg2+, influenced by geological processes in Triassic, Carboniferous, and Permian rock formations. It was published by Geoscience Australia Data and was last updated on 2026-05-14.

Use Cases

• Modeling groundwater solute transport based on described silicate and carbonate dissolution/precipitation reactions.
• Analyzing hydrochemical facies and evolution based on ion exchange and dispersion processes mentioned in the description.
• Assessing groundwater salinity sources based on the described legacy of Permian marine salts and sulphide oxidation.
• Studying mineral saturation states (e.g., calcite, dolomite, dawsonite) using disequilibrium indices referenced in the data.

Strengths

• Description details specific geological formations (e.g., Wollombi Coal Measures, Greta Coal Measures) and hydrochemical processes.
• Last updated date is explicitly provided: 2026-05-14 04:48:13.009668.

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 of the upper Hunter River valley.
