Groundwater Hydrogeochemistry in Fractured Bedrock Aquifers at Yass, NSW

Groundwater samples from fractured bedrock aquifers beneath dryland salinity sites in the Yass region of New South Wales, Australia. The data likely contains chemical composition of major cations and anions, with salinity ranging from 250 to 2250 mg/L. The dataset is hosted by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Modeling hydrochemical evolution based on described processes of mineral dissolution and oxidation.
• Analyzing ion exchange reactions based on the presence of clay in fractures and veins.
• Investigating redox conditions based on microbially mediated reactions with organic matter.
• Classifying groundwater types based on the described range of salinity and chemical composition.

Strengths

• Specific salinity range provided (250 to 2250 mg/L).
• Detailed description of geological contexts (slates, shales, sandstones, dacite).
• Clear explanation of three key hydrochemical processes generating the data.

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 catchments studied.
