HAZWASTE EXPERIENCE

 Among the earliest contributors to the theory of flow through fractured media and groundwater transport of contaminants, Dr. Snow worked on the movement of radionuclides in both saturated and unsaturated environments at the Nevada Test Site, the Basalt Waste Isolation Plant, WA, and the Waste Isolation Pilot Plant, Carlsbad, NM. He has modeled or reviewed models of groundwater transport beneath landfills at Superfund and RCRA sites for the EPA and states. He has worked on acid mine drainage and tailings effluent problems, aquifer contamination studies and fluid injection programs.
