Sustainable management of coastal groundwater resources and opportunities for further development
Waterlines report No 79 - March 2012
Many coastal communities depend on freshwater from coastal dune aquifers to meet potable demand. As populations in coastal communities grow, the increased demand for groundwater must be managed sustainably.
This Waterlines report summarises the findings from the Sustainable Management of Coastal Groundwater Resources project, which investigated numerous aspects of the Macleay Sand Aquifer on the NSW Central Coast.
The report provides a summary of the project and presents the key findings and conclusions from information gathered on hydrogeology and hydrochemistry, flow modelling, groundwater-dependent ecosystems, groundwater condition indicators, and a socio economic assessment.
The report also details the implications of these findings for water management in the Kempsey Shire Council, as well as applicability to the management of coastal dune aquifer systems across Australia.
The findings of this project and the tools developed will better enable the region’s water resource managers to manage the coastal dune aquifers sustainably so that these systems can continue to provide potable water for their communities while supporting the unique ecosystems that depend on them. Many of the methodologies and tools developed for the project can be applied to similar coastal areas across Australia to ensure their groundwater resources are managed sustainably.
