Groundwater Hydrochemistry Beneath Dryland Salinity Sites at Yass

Fresh to brackish groundwaters with total dissolved solids ranging from 250 to 2250 mg/L occur in fractured bedrock aquifers. The dataset describes the chemical composition and origins of these waters in three catchments near Yass, New South Wales. It was published by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Classify hydrochemical water types based on concentrations of major cations and anions.
• Model ion-exchange and reverse ion-exchange processes using data on clay presence in fractures and veins.
• Analyze microbially mediated redox reactions through metrics on organic matter and redox potential.
• Correlate groundwater chemistry with local geology, such as slate, shale, sandstone, dacite, and rhyodacite bedrock.

Strengths

• Defines specific salinity range of 250 to 2250 mg/L total dissolved solids.
• Identifies three distinct geological catchments and their bedrock compositions.
• Describes three key chemical processes governing water composition.

Limitations

• No quantitative data tables or row/column counts are provided in the description.
• Sample data and file formats (PDF, HTML) suggest the primary data may be embedded in narrative reports.
• Geographic scope is limited to three specific catchments near Yass, NSW.
