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.

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.Read moreRead less
