John Pickens’ experience encompasses field site characterization, model development, groundwater and vadose zone flow and transport modeling, water resources development, remedial investigation/feasibility studies, and radioactive waste site evaluations and permitting. He has broad experience in designing, performing, and interpreting well hydraulic and tracer tests to determine formation properties of both porous and fractured media. He provides senior input and review on development of conceptual models and parameter input distributions, data analysis, model calibration and sensitivity analysis, and reporting. For water resource evaluations, he has managed groundwater availability modeling projects to address long-term water supply planning. He is a recognized expert and has provided testimony support related to groundwater modeling and subsurface contamination evaluation on litigation projects including cases involving release of petroleum hydrocarbons from oil and gas exploration and development activities. John has conducted site characterization and/or modeling to support environmental restoration and radioactive waste disposal programs at several federal government sites. John serves as a principal at INTERA has has managed large multi-disciplinary site characterization, groundwater flow and transport modeling, and waste management projects and has supported radioactive waste-management programs in the United States, Australia, Canada, France, Switzerland, and the United Kingdom. He has authored or co-authored numerous journal articles on hydraulic and tracer testing and groundwater/transport modeling.
