Mr. Pohlmann's experience and interests include characterization and analysis of hydrogeologic frameworks, groundwater flow, and contaminant transport through field data collection, interpretation and modeling. Field investigations focus on delineation of local and regional groundwater flow systems in the Great Basin and Mojave Deserts. The modeling emphasizes a stochastic approach, incorporating spatial variability in hydrogeologic parameters and the uncertainty in estimating these parameters, and has been used for development of conceptual models, site characterization and closure, delineation of wellhead protection areas, and development of risk assessments.
