Course Reviews (4.7/5): 

Overview: This course provides a comprehensive overview of the transport and fate of common and legacy agrochemicals including insecticides, herbicides, nitrogen, phosphorus and additives (e.g., 1,4-dioxane and nitrapyrin). Agrochemical best management practices (BMPs) and commonly employed remediation technologies are also presented. Course sections are applicable to professionals working in surface water, stormwater, and groundwater quality management. The topics provide essential information for understanding and managing agrochemical pollutants for environmental protection and compliance.
