Dr. Robert Lerch

Dr. Lerch's research encompasses the fate and transport of agricultural-derived contaminants, such as sediment, nutrients, and pesticides, and their impacts on water quality. His research focuses on understanding the factors controlling herbicide transport from fields to streams, including regional-scale assessments of watershed vulnerability to herbicide contamination, development and testing of best management practices (BMPs) to reduce contaminant transport, and long-term monitoring of stream water quality to assess trends. His new research includes studying the effect of cropping systems on greenhouse gas emissions and landscape position on denitrification.  

Dr. Lerch also serves as a member of MOKEG (Missouri Karst Ecosystem Group) for the research project Water Quality and Aquatic Biological Assessment of Hunter's and Devil's Icebox Caves, Boone County, Missouri.
