Overview: This practical and highly acclaimed course provides a comprehensive overview of stormwater pollution chemistry and its applications to stormwater management and treatment. Topics include an overview of stormwater pollutant classes, sources, characteristics, transport and fate, source control, treatment best management practices (BMPs), BMP performance studies, recent research, and emerging technologies. Other topics include the potential for stormwater to cause groundwater and surface water contamination. Participant course evaluations average 4.8 out of 5 (96%) and often praise the instructor for his knowledge, teaching style, and enthusiasm.
