Riparian revegetation is a key tool used to improve water quality outcomes for both the environment and downstream drinking water supplies. I am currently using a unique interdisciplinary approach, combining field and laboratory techniques from ecology, soil biogeochemistry, organic chemistry and toxicology to advance our understanding of the nature of dissolved organic matter derived from different plant species, and its affect on aquatic ecosystem function and toxicity of drinking water post-chlorination. This is an Australian Research Council Linkage Project with industry and independent organisation project partners.
Previously at the Australian Rivers Institute I conducted research on a range of industry funded projects. I took a leadership role in planning and undertaking field and laboratory work, analysing data, writing reports and producing peer-reviewed publications. These included:
1. Investigating in-channel nitrogen removal via denitrification in the Upper Brisbane River. This project seeks ways to enhance this processes and reduce downstream nitrogen loads.
2. Studying the impacts of nutrients released from flood plume sediments on freshwater and marine algae. This work aims to identify indicators that can be used to predict the effects of sediment derived from different soil types on the algal community.
3. Understanding the factors leading to poor taste and odour quality in the Mid Brisbane River. This project will inform decisions on the management of the river to the improve the quality of the raw water extracted at Mt Crosby for treatment and supply to Brisbane city.
