Brief description Soil acidity is a major geo-environmental problem in coastal Australia, whereby acidified groundwater pollutes estuaries with catastrophic consequences on local aquaculture (e.g. fish, oyster and prawn farming) and agricultural industries. The project aims to optimise the design and performance of permeable reactive barriers (PRBs) utilising waste materials such as recycled concrete and oyster shells for neutralising groundwater acidity prior to discharge to waterways. The main research includes the study of potential clogging and fouling of these PRB materials due to chemical reactions and to develop a predictive tool for long-term PRB performance as a means of ground acidity alleviation.
