Mr. Sean Kosinski has 14 years of consulting experience, and his primary area of expertise is in numerical simulation of hydrologic systems. He has worked on and managed projects that involved modeling large-scale dewatering operations at open-pit and underground mines; simulating fate and transport of metals, VOCs, and chlorinated solvents; designing bioremediation systems and assessing their performance; optimizing remediation systems; designing monitoring networks; and simulating transport of radionuclides in fractured rock using stochastic methods. His experience as a groundwater modeler includes developing deterministic and stochastic flow and transport models and their calibration using inverse methods, performing independent reviews of groundwater investigations and models, developing basin-scale hydrologic budgets, and acquiring and statistically analyzing field and laboratory data. Mr. Kosinski is well versed in hydrologic field methods, including the planning, implementation, and interpretation of tracer, pumping, and slug testing; geologic log interpretation; and vadose zone monitoring. Recently, he has worked to support council on several multiparty litigation cases involving contaminant fate and transport. His recent work in the mining sector helped to resolve permitting and compliance issues with federal and state regulators. Examples include facilitating contaminated site closure at sites as complex as those at the Nevada Test Site and coordinating responses to public comments on EISs for mining clients.
