Robert GreenwaldMr. Greenwald has more than 20 years of experience in optimization of groundwater extraction and treatment systems, capture zone evaluation, numerical modeling, hydrogeologic evaluations, and project management. He is the primary author of a recently published USEPA document on capture zone evaluation for pump-and-treat systems, and he has presented short courses on capture zone analysis to EPA headquarters, nine EPA regions, and 3 state agencies. He has co-managed a nationwide optimization project for groundwater pump-and-treat systems using the RSE process, and has participated in approximately 50 RSE's at Superfund, DOE, RCRA, and UST sites. He has an extensive background with groundwater modeling and technology transfer, and has served as a co-instructor of annual groundwater modeling courses (beginning and advanced) at the International Groundwater Modeling Center for nearly 15 years. He has been the project manager for a Superfund site in New Jersey for approximately 10 years which has included focused site characterization, risk assessment (ecological and human health), groundwater modeling, a feasibility study, remedial design, remedial construction, O&M, and long-term monitoring.
