Sustainability of aquifer storage and recovery: the effects of nutrient load and water quality on aquifer clogging. Aquifer storage and recovery, ASR, stores excess water or treated effluent for subsequent beneficial use. Microbial and geochemical reactions can through clogging reduce aquifer permeability, increase pumping cost and may threatened the sustainability of the system. The relationships between injectant composition and biological geochemical clogging are poorly understood. Expanding on prior field and column studies and techniques this project will study geochemical and microbial processes at on well-instrumented ASR trial site in South Australia. The relationship between effluent composition and change in hydraulic conductivity will be quantified, with a view to developping generic, practical decision-support tools and improve predictive model.

含水层储存和恢复的可持续性：营养负荷和水质对含水层堵塞的影响。含水层储存和回收，ASR，储存多余的水或处理后的污水，以供随后的有益使用。微生物和地球化学反应会通过堵塞降低含水层的渗透率，增加抽水成本，并可能威胁到系统的可持续性。注入剂组成与生物地球化学堵塞之间的关系知之甚少。该项目将在先前实地和专栏研究和技术的基础上，在南澳大利亚州一个仪器齐全的ASR试验场研究地球化学和微生物过程。将量化污水成分与渗透系数变化之间的关系，以期开发通用、实用的决策支持工具，并改进预测模型。
