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

The Australian Ocean Data Network provides hydrogeochemical data for groundwater in the upper Hunter River valley of New South Wales. The description details chemical processes like silicate dissolution, ion exchange, and oxidation of coals and sulphides across various geological formations. The dataset was last updated on 2026-06-05.

Use Cases

• Modeling groundwater chemistry evolution based on described silicate and carbonate dissolution/precipitation reactions.
• Analyzing the influence of geological formations like the Greta Coal Measures on groundwater salinity.
• Studying the distribution of solutes like calcium, silica, and bicarbonate which are mentioned as approaching log-normal distributions.
• Investigating the legacy of marine salts and oxidation processes in Permian rock aquifers.

Strengths

• Description provides detailed scientific context on chemical processes and geological formations.
• Data is associated with a specific, well-defined geographical region: the upper Hunter River valley, New South Wales.
• Last update timestamp (2026-06-05) is precisely recorded.

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.
• Primary file formats are PDF and HTML, which may require extraction for structured analysis.
