The hydrogeochemistry of groundwater in fractured bedrock aquifers beneath dryland salinit

Fresh to brackish groundwaters in the range of 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, provided by Geoscience Australia Data, describes the chemical composition of these waters, which originate from recent meteoric sources and are shaped by water-rock interactions, ion exchange, and microbial processes. The data was last updated on 2026-04-30.

Use Cases

• Modeling groundwater flow and geochemical evolution based on described hydrochemical types and processes.
• Assessing salinity sources and mitigation strategies based on ion concentrations and redox conditions.
• Studying water-rock interaction processes in specific lithologies like slates, shales, sandstones, and dacites.
• Analyzing the impact of microbial activity on groundwater chemistry based on described low redox potentials.

Strengths

• Specific salinity range provided (250 to 2250 mg/L).
• Clear description of geological contexts across three named catchments (Dicks Creek, Williams Creek, Spring Creek).
• Detailed explanation of three key hydrochemical processes shaping the water composition.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data files are in PDF and HTML formats, which may complicate direct computational analysis.
