Summary
👤
Senior🎓
Top SchoolDave Dahlstrom is a Senior Hydrogeologist with over three decades of hands-on experience and eight years in his current senior role, specializing in numerical simulation, inverse modeling, and predictive uncertainty for groundwater flow and contaminant transport. He designs and evaluates complex water-supply and remediation systems—from high-capacity radial collector well fields to pump-and-treat and dewatering schemes—using a broad suite of groundwater codes (MODFLOW variants, MT3D, SEAWAT, GFLOW, PATH3D) and geochemical tools. Dave has led aquifer testing and site characterization across diverse hydrogeologic settings (karst, fractured rock, alluvial fans, glacial outwash) and translated those data into robust model calibrations and risk-based decisions for municipal, industrial, and environmental projects. Notably, he has applied his modeling expertise to PFAS fate and transport, heat and solute transport, and flood impacts on riverbank filtration systems, combining field-tested aquifer tests with advanced simulation to reduce predictive uncertainty. Based in Bloomington, Indiana, he blends academic experience in finite-element code benchmarking with decades of consulting practice, making him equally comfortable debugging models and directing large applied investigations.
