Daniel F. Cornacchiulo, Environmental Assessment and Remediations Daniel F. Cornacchiulo, Ph.D., Engineer/Hydrogeologist has ten years of experience in the environmental consulting field. Dan’s modeling expertise includes development of a finite-difference computer code for tidal influence on unconfined aquifers. His current research involves numerical modeling of pollution source identification using the Marching-Jury Backward Beam Equation (MJBBE) and the Quasi-Reversibility methods. This research includes stability analysis of the backward methods, applying real life conditions such as sampling densities and uncertainties for the MJBBE. Dr. Cornacchiulo holds a B.A.Sc. in geology from the SUNY Binghamton and a M.Sc. and Ph.D. in Civil Engineering and Engineering Mechanics at Columbia University.

Jennifer A. Lawrence, Environmental Assessment and Remediations Jennifer graduated from Long Island University in 2000 with a BA in Environmental Studies and has seven years of experience in the investigation and remediation of petroleum impacted sites. She has been involved in numerous research initiatives with the New York State Department of Environmental Conservation (NYSDEC) involving the implementation of new and innovative remedial technologies, public and private potable well impacts, compound specific stable isotope analysis and aerobic biological remediation. She has been with Environmental Assessment and Remediation since 2003 and is currently the Senior Project Manager.

Donald A. Trego, Environmental Assessment and Remediations Don graduated in 1993 from the Pennsylvania State University with a bachelors of science in Environmental Resource Management. He has over 14 years of experience in the groundwater remediation industry. Don has been involved in numerous research initiatives with the New York State Department of Environmental Conservation (NYSDEC), the United States Environmental Protection Agency (USEPA), and the United States Geological Survey (USGS). As project manager, Don was a co-recipient of the 2004 National Ground Water Association’s (NGWA) – Outstanding Groundwater Remediation Project award. He currently is the Vice president of a respected environmental consulting firm located on Long Island, NY.

Joseph Haas II, M.S., PE, New York State Department of Environmental Conservation Joe has 19 years experience working as a state regulator managing a remedial section. He holds both an Engineering Geologist and a Hydrogeologist specialty license. Joe cooperated in research with the US EPA and the USGS focused upon the analysis of the environmental fate and transport of the gasoline additive Methyl tertiary butyl ether (MTBE). Some if his contributions have been credited as having influenced the national debate on the use of MTBE in gasoline. These contributions were acknowledged, in 2002, by the US EPA, ORD in the form and an award for Exceptional Support to ORD.

Dominique Sorel, S.S. Papadopulos and Associates Inc. DOMINIQUE SOREL, M.SC., ENG., Hydrogeologist, has more than ten years of experience in the investigation of contaminated sites, groundwater modeling, the evaluation of innovative groundwater remediation technologies and remedy performance. Her experience has involved litigation support; site characterization; application and monitoring of in-situ groundwater treatments, including zero-valent iron permeable reactive barriers; evaluation of innovative groundwater sampling techniques; and tracer test design. Ms. Sorel holds a B.A.Sc. in civil engineering from the Université de Sherbrooke and a M.Sc. in hydrogeology from the University of Waterloo and is a registered professional engineer in Québec.

Matthew J. Tonkin, S.S. Papadopulos & Associates Inc. Matt Tonkin has been with SSP&A for 12 years. His focus is on the design of data gathering efforts; the synthesis and interpretation of data; and, the application of models to support decision-making. He has completed contracts to the USGS, USEPA and California Department of Water Resources in the areas of contaminant transport and model uncertainty analysis. Matt is a former member of the Interstate Technology Research Council (ITRC) MTBE team, and has provided support to NYSDEC at several fuel-spill investigations and remedies.

Gilbert Barth, Ph.D., S.S. Papadopulos and Associates Inc. Dr. Barth received his doctorate working with Tissa Illangasekare and Mary Hill. He completed a National Academy of Sciences, post-doctoral fellowship at the U.S. Geological survey. Since the post-doctorate he has worked in consulting, with SSPA since 2003. His emphasis in more recent years has been on assessing the sensitivity of riparian zone and surface water/groundwater interaction to anthropogenic changes.
