Mechanistic and probabilistic approaches to assessing the impact of pesticide mixtures in Australian waterways. This project will provide vital information on the impacts of pesticide mixtures in Australian waterways and will also provide information with respect to safe levels of pesticides for water quality management.

This project will provide vital information on the impacts of pesticide mixtures in Australian waterways and will also provide information with respect to safe levels of pesticides for water quality management. This information will be used to develop scientifically sound management policies and provide advice to regulatory authorities such as the NSW Department of Environment and Conservation and the Federal Department of Environment and Heritage. Specifically the results will contribute to ensuring the use of pesticides in market gardens close to Sydney does not threaten the health of local rivers. Read moreRead less
Environmental risk assessment of acid sulfate soil formation and pollutant generation in Swan Coastal Plain. The urgency and importance of securing water sources for human use in a sustainable manner is dictated by drying climate and rapid population expansion in Australia. Dropping groundwater levels (less recharge, increased abstraction, enhanced drainage) result in formation of acid sulfate soils in oxidised layers that contain acid-bearing minerals. This project will produce an environmental ....Environmental risk assessment of acid sulfate soil formation and pollutant generation in Swan Coastal Plain. The urgency and importance of securing water sources for human use in a sustainable manner is dictated by drying climate and rapid population expansion in Australia. Dropping groundwater levels (less recharge, increased abstraction, enhanced drainage) result in formation of acid sulfate soils in oxidised layers that contain acid-bearing minerals. This project will produce an environmental risk assessment framework as a basis for (i) educated decisions regarding land development and soil disturbance vs conservation as well as (ii) identifying areas suitable for water abstraction from groundwater resources. This will ensure sustainable use of precious groundwater resources in this drying continent of ours.Read moreRead less
