He specializes in analysis of soil, groundwater, and stormwater treatment alternatives, cost estimation, and design and implementation of remedial actions, from pilot- to full-scale systems. Mr. Martin has substantial experience developing cost-effective alternatives for site remediation, and litigation and property transfer projects.
Dr. Grace Chang is a consultant in limnology and oceanography. She has more than 20 years of experience performing site assessments, including hydrodynamics, sediment transport, particle dynamics, and marine and hydrokinetic energy. Dr. Chang has managed programs involving field operations, data processing and analysis, and numerical modeling for environmental characterization, and scientific research.
Mr. Steve Helgen is a consultant specializing in geochemistry, hydrogeology, and environmental forensics. He has more than 20 years of experience in contaminant fate and transport, geochemical fingerprinting, and apportionment in complex, multiparty environmental disputes involving sediments, groundwater, and industrial facilities. Mr. Helgen has provided expert testimony in both state and federal courts.
Mr. Damian V. Preziosi is an environmental scientist with more than 20 years of experience evaluating potential ecological and human health risks associated with exposures to physical, chemical, and biological hazards. He supports clients in North America, South America, Europe, and Asia for work in the energy, chemical, and mining sectors.
Mr. Todd Martin is a professional engineer and hydrogeochemist. He has 22 years of experience specializing in environmental engineering, the transport and fate of inorganic and organic chemicals in the environment, and analysis of remediation alternatives. Mr. Martin’s background encompasses aqueous and soil geochemistry, hydrogeology, hydrodynamics and sediment transport, and engineering design and cost analysis.
Mr. David Livermore is a principal hydrogeologist and geochemist with 30 years of experience in solving complex earth science problems centered on the interaction of hydrogeologic, geologic, and atmospheric systems. He is a registered professional geologist in six states and a licensed hydrogeologist in Washington.
Mr. Patrick Gwinn has more than 25 years of experience applying his expertise in human health and ecological risk assessment, water quality, fate and transport dispersion modeling, product stewardship, air toxics sampling, and hazardous waste management. He has been instrumental in developing and leading projects aimed at establishing site-specific ambient water quality criteria and pollutant discharge limits.
Dr. Marcia Greenblatt is a water resources engineer with nearly 20 years of specialized experience in hydrodynamic, water quality, and sediment investigations. She has extensive involvement in CERCLA remedial investigations and feasibility studies at large sediment sites. Her responsibilities have included design of sediment, water column, and bathymetric data collection programs and field sampling plans.
Mr. Gene Revelas is a leading scientist on contaminated sediment and dredged material management issues. He is one of the few North American scientists with extensive experience in the use of sediment-profile image technology for characterizing dredged material disposal sites and benthic habitats and has applied this technology at freshwater, estuarine, and marine sites nationwide and abroad.
Mr. Avram Frankel is a program manager with nearly 30 years of experience working on a wide range of commercial/industrial, municipal, state, and federal sites regulated under a variety of regulatory programs. Licensed in four states, he provides clients with strategic management and technical analysis of due diligence, redevelopment, technology evaluation, remediation, and litigation matters.
