Benjamin Hagedorn

Benjamin Hagedorn is a Professor in the Department of Geological Sciences at California State University, Long Beach. His research integrates geochemistry, hydrology, and environmental science to study carbon and water cycles. His work examines fluvial inorganic carbon transfer, chemical weathering of silicate lithologies, and groundwater-surface water interactions.

• Education: Ph.D. in Geosciences (Monash University, 2010), M.S. in Geology (RWTH Aachen, 2006), Post-doctoral Researcher (University of Hawaii at Manoa, 2010-2011)

Research Interests focus on watershed-scale geochemical processes, including:

• Impact of urban and agricultural development on carbon transport
• Mineralogical effects of chemical weathering for CO₂ sequestration
• Groundwater recharge mechanisms and aquifer dynamics
• Temporal and spatial variability of water quality under climate stressors

Publication Trends emphasize interdisciplinary approaches to water sustainability, with recent studies on contaminated water risk assessment, submarine groundwater discharge, and drought-induced pollutant mobilization. His methods combine field surveys, geochemical analysis, numerical modeling, and GIS technologies.

Research Group leads projects such as:

• Groundwater age dating and signal processing
• VOC pollutant source tracking in urban environments
• Freshwater availability on arid islands (Catalina, California)
• Ecological impacts of SGD on coral reefs (Mo'orea, French Polynesia)
• Aquifer vulnerability in agricultural regions (Central California)
• Drought effects on geogenic pollutant mobilization
