Hydrogeological Survey of Bathurst Island Mission Water Supply

Geoscience Australia Data conducted an inspection to select a bore site for domestic water on Bathurst Island. The report details the Cretaceous mudstone geology, a poor aquifer over 1,000 feet thick, and a laterite plateau only slightly more than ten feet thick that hosts the water supply. Recommendations include deepening existing wells and drilling radial horizontal holes to find water-bearing cavities, while addressing pollution risks from uncovered wells.

Use Cases

• Site suitability analysis for water bore placement based on geological formation descriptions.
• Pollution risk assessment for water wells in areas with contamination concerns mentioned in the description.
• Hydrogeological modeling of aquifer potential in Cretaceous mudstone and laterite plateaus.
• Planning water infrastructure improvements based on recommendations to deepen wells and install protective curbs.

Strengths

• Report includes specific geological measurements, such as a Cretaceous mudstone layer at least 1,000 feet thick and a laterite layer slightly more than ten feet thick.
• Provides concrete engineering recommendations for well modification and pollution mitigation.

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 solely on Bathurst Island Mission.
