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.

农药污染地表水和地下水的风险评估-快速迁移的触发机制。农药和除草剂进入地下水和地表水对环境和人类都构成了风险。将开发一种新的基于事件的农药向地表水和地下水迁移风险评估方法。利用降雨模拟，将在农业集水区对地表径流和渗透之间的分区进行量化。农药污染事件将从气候数据中确定，如高强度的降雨和控制径流和优先流的土壤特性。研究结果将用于制定管理战略，以减少农药的异地流动。
