Abstract: This report documents a hydrogeological data review and assessment for Numbulwar and the surrounding region covering an area of ~40 km2. The area encompasses two key hydrogeological units: (i) the Quaternary Coastal Deposits and (ii) the Cretaceous Beds. Sand aquifers hosted in the Coastal Deposits are currently exploited for community water supplies, whereas sandstone aquifers hosted in Cretaceous Beds have only had historical investigations. The assessment considered data in the context of: (i) understanding the potential sustainability of the current water source and (ii) identifying and prioritising technical works and infrastructure requirements to underpin long-term water security. An integrated interpretation of data has proved invaluable for: (i) refining the existing hydrogeological conceptual model for the sand aquifers; (ii) evaluating the ability of the current borefield in the sand aquifers for meeting community water demand and (iii) evaluating opportunities, risks and technical requirements for expanding development of the current aquifers or further exploring and developing the Cretaceous sandstone aquifers.
