Groundwater Hydrogeochemistry in Fractured Bedrock Aquifers at Yass, NSW

Fresh to brackish groundwaters ranging from 250 to 2250 mg/L occur in fractured bedrock aquifers beneath dryland salinity sites at Yass in the Southern Tablelands of New South Wales. The dataset, sourced via the Australian Ocean Data Network, describes the chemical composition of these waters, which originate from recent meteoric sources and represent various hydrochemical types. Chemical processes include water-rock interaction, ion exchange, and microbially mediated reactions with organic matter.

Use Cases

• Modeling hydrochemical evolution based on described water-rock interaction processes.
• Analyzing salinity sources and ion exchange reactions in fractured bedrock aquifers.
• Investigating redox conditions and microbial influences on groundwater chemistry based on the described low redox potentials.

Strengths

• Describes a specific salinity phenomenon with a defined geographic scope at Yass, NSW.
• Provides detailed hydrochemical process descriptions including dissolution, oxidation, and ion exchange.

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 Australian region.
