Risk Assessment of Pesticide Contamination of Surface Water and Groundwater - Trigger Mechanisms for Fast Transport. Pesticide and herbicide transport to groundwater and surface water poses a risk to the environment and humans alike. A new event-based risk assessment approach of pesticide movement to surface water and groundwater will be developed. With the use of rainfall simulation partitioning between surface runoff and infiltration will be quantified in an agricultural catchment. Pesticide c ....Risk Assessment of Pesticide Contamination of Surface Water and Groundwater - Trigger Mechanisms for Fast Transport. Pesticide and herbicide transport to groundwater and surface water poses a risk to the environment and humans alike. A new event-based risk assessment approach of pesticide movement to surface water and groundwater will be developed. With the use of rainfall simulation partitioning between surface runoff and infiltration will be quantified in an agricultural catchment. Pesticide contamination events will be identified from climatic data such high intensity rainfalls and soil properties controlling runoff and preferential flow. Results will be used to develop management strategies to reduce offsite movement of pesticides.Read moreRead less
Anticipating closure of bauxite refineries in Western Australia: the water quality implications of a proposed new design in residue storage areas. Refining bauxite is a major industrial activity in Australia, with economic benefits and a high potential for environmental impact. Many bauxite refineries are sited in rural areas. Community interests are given high priority in developing strategies for long-term storage of residue. These community interests include minimal impact on farmland, water, ....Anticipating closure of bauxite refineries in Western Australia: the water quality implications of a proposed new design in residue storage areas. Refining bauxite is a major industrial activity in Australia, with economic benefits and a high potential for environmental impact. Many bauxite refineries are sited in rural areas. Community interests are given high priority in developing strategies for long-term storage of residue. These community interests include minimal impact on farmland, water, health and natural ecosystems. Some of the refinery residue can be re-used in applications such as road construction, thus reducing the need to find other materials for this purpose. This project will investigate new residue management practices which could lead to better ways of establishing a sustainable vegetation cover and avoiding the impact of drainage water on the environment.Read moreRead less
