Instructor: Erick McWayne, NEMA, LLC

: This course provides participants with an improved understanding of stormwater pollution chemistry and its applications to stormwater monitoring, treatment, and program management. Topics include a thorough overview of stormwater pollutant types, sources, characteristics, behavior, source control, treatment best management practices (BMPs), BMP performance monitoring, recent research, and emerging technologies. Other topics include the potential for stormwater infiltration to cause groundwater and surface water contamination.
