"Nonpoint source pollution in agricultural landscapes: Assessment, monitoring, regulation, and management"



Most of California’s $40 billion irrigated agricultural sector is located in California’s Central Valley. Groundwater is a critical source of drinking water throughout the region. This presentation will highlight work by the Central Valley Regional Water board in developing groundwater-focussed permitting programs for dairies and irrigated lands as well as new framework for integrated management of salt and nitrate discharges from all sources to groundwater and surface water. The first decade of these permitting efforts focused on developing detailed groundwater quality assessments that clearly linked agriculture to groundwater nitrate.

Thomas Harter is the Robert M. Hagan Endowed Chair for Water Resources Management and Policy at the University of California, Davis. He holds a joint appointment as Professor and Cooperative Extension Specialist in the Department of Land, Air, and Water Resources, is currently chair of the Hydrologic Sciences Graduate Group, and, as Associate Director of the Center for Watershed Sciences, is a team partner for the World Water Center. Dr. Harter received his BS and MS in Hydrology from the Universities of Freiburg and Stuttgart, Germany; and his PhD in Hydrology from the University of Arizona.  Dr. Harter's research and extension emphasizes the nexus between groundwater and agriculture. His research group focuses on nonpoint-source pollution of groundwater, sustainable groundwater management, groundwater and vadose zone modeling, groundwater resources evaluation under uncertainty, groundwater-surface water interaction, and on contaminant transport. His work uses a range of numerical, statistical, and stochastic modeling approaches, often with field research, to evaluate the impacts of agriculture and human activity on groundwater flow and contaminant transport.
