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 dataset includes chemical composition data for major cations and anions, with salinity ranging from 250 to 2250 mg/L. It was published by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Classifying hydrochemical water types based on major ion concentrations.
• Modeling water-rock interaction processes in fractured bedrock recharge zones.
• Investigating ion-exchange reactions with clay in bedrock fractures and veins.
• Studying microbially mediated redox reactions with organic matter in groundwater.

Strengths

• Specific salinity range provided (250 to 2250 mg/L).
• Geological context for three distinct catchments (Dicks Creek, Williams Creek, Spring Creek) is described.
• Key hydrochemical processes (dissolution, oxidation, ion-exchange, microbial reactions) are documented.

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 on a specific region of New South Wales.
