Groundwater Hydrochemistry in Fractured Bedrock Aquifers at Yass, NSW

Yass in the Southern Tablelands of New South Wales is the location for this dataset of fresh to brackish groundwaters. The data, provided by Geoscience Australia, describes groundwater chemistry from fractured bedrock aquifers beneath dryland salinity sites. The chemical composition is derived from processes including water-rock interaction, ion exchange, and microbially mediated reactions.

Use Cases

• Modeling salinity evolution in groundwater based on described hydrochemical processes.
• Analyzing water-rock interaction effects based on the major cation and anion composition.
• Studying the influence of bedrock geology on groundwater chemistry based on the described slate, shale, sandstone, and dacite lithologies.

Strengths

• Specific geographic focus on three catchments (Dicks Creek, Williams Creek, Spring Creek) in Yass, NSW.
• Describes the origin of groundwater as recent meteoric waters and details three key chemical processes shaping its composition.

Limitations

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