The urgency and importance of securing water sources for human use in a sustainable manner is dictated by drying climate and rapid population expansion in Australia. Dropping groundwater levels (less recharge, increased abstraction, enhanced drainage) result in formation of acid sulfate soils in oxidised layers that contain acid-bearing minerals. This project will produce an environmental risk assessment framework as a basis for (i) educated decisions regarding land development and soil disturbance vs conservation as well as (ii) identifying areas suitable for water abstraction from groundwater resources. This will ensure sustainable use of precious groundwater resources in this drying continent of ours.

澳大利亚干燥的气候和快速的人口增长决定了以可持续的方式确保人类使用水源的紧迫性和重要性。地下水位下降(补给减少、抽取增加、排水加强)会在含有酸性矿物的氧化层中形成酸性硫酸盐土壤。该项目将产生一个环境风险评估框架，作为(I)关于土地开发和土壤干扰与养护的明智决定的基础，以及(Ii)确定适合从地下水资源中取水的地区。这将确保在我们这片干旱的大陆上可持续地使用宝贵的地下水资源。
