Acid sulfate soils impact over 8 million ha of valuable coastal land in Australia, and over 24 million ha throughout the world. Drainage from acid sulfate soil waterways is a major threat to water quality, ecosystem health, agricultural sustainability and fisheries productivity. The practical benefits of this project arise from an improved understanding of the processes controlling water quality and associated resources in these areas. The intellectual benefits include the development of novel geochemical concepts involving sulfur minerals that are central to coastal rivers, wetlands and estuaries. This project will enhance Australia's capacity for sustainable environmental management.

酸性硫酸盐土壤影响澳大利亚800多万公顷宝贵的沿海土地，在全世界影响2400多万公顷。酸性硫酸盐土壤水道的排水是对水质、生态系统健康、农业可持续性和渔业生产力的主要威胁。该项目的实际效益来自于对这些地区水质控制过程和相关资源的更好理解。知识方面的好处包括开发新的地球化学概念，涉及对沿海河流、湿地和河口至关重要的硫矿物。该项目将提高澳大利亚可持续环境管理的能力。
