John Pickens is a hydrogeologist with professional experience in 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. 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 has performed or managed a wide variety of groundwater flow and contaminant transport modeling investigations. He serves as project manager on large multidisciplinary hydrogeologic and waste management projects. He is experienced in the development of innovative methods for site characterization and remediation of dense non-aqueous phase liquid contaminants. He has managed site characterization and/or performance assessment projects to support national radioactive waste management programs in the U.S. [Waste Isolation Pilot Plant (WIPP)], Canada (AECL), Switzerland (Nagra), and France (ANDRA). He has U.S. Department of Energy project experience at the WIPP, Sandia National Laboratories, Savannah River Site, Paducah Gaseous Diffusion Plant, Nevada Test Site, and Yucca Mountain Site. He has managed the development of several groundwater availability models for major and minor aquifers in Texas under contracts with the Texas Water Development Board. He has provided expert report and testimony support on litigation projects. He has conducted projects in the states of Arizona, California, Florida, Nevada, New Mexico, Ohio, South Carolina, and Texas, as well as international projects in Canada, France, the United Kingdom, Sweden, and Switzerland.
