Hydrogeochemistry of Upper Hunter River Valley Groundwater in New South Wales

Geoscience Australia Data provides hydrogeochemical data for groundwater in the upper Hunter River valley of New South Wales. The dataset describes the chemistry of groundwater in regional recharge zones, influenced by silicate and carbonate reactions, ion exchange, and oxidation processes within Triassic, Carboniferous, and Permian rock formations. It was last updated on 2026-03-25.

Use Cases

• Modeling groundwater solute transport based on described ion distributions and log-normal concentrations of Ca2+, SiO2, and HCO3-.
• Analyzing geochemical processes like silicate dissolution and carbonate precipitation based on disequilibrium indices for minerals like calcite and dawsonite.
• Investigating the influence of geological formations (e.g., Wollombi Coal Measures, Greta Coal Measures) on groundwater salinity and chemistry.
• Studying the legacy of marine salts and sulfide oxidation in Permian rock aquifers as described in the dataset.

Strengths

• Data is sourced from Geoscience Australia, a national geological survey authority.
• Description provides detailed geochemical context for processes like ion exchange, mineral dissolution/precipitation, and oxidation.
• Last updated date is explicitly provided: 2026-03-25 17:05:02.032508.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific upper Hunter River valley study area.
