Environmental Forensics in Litigation and Allocation: Integral Consulting Presents at INEF

Graham AnsellIn the world of CERCLA liability, the Centredale Manor Restoration Project Superfund site provides a unique case history.  Rarely has a notified potentially responsible party argued in court against the regulatory agency and U.S. Department of Justice, and in some instances, received a favorable adjudication.  Graham Ansell, Ph.D., of Integral Consulting Inc. (Integral), will describe perspectives of this case, along with litigation strategy, at the June 25–27 meeting of the International Network of Environmental Forensics (INEF).  Held in Salt Lake City, Utah, the INEF meeting features ideas and research relating to the field of environmental forensics. In his presentation “Centredale Manor Superfund Site – A Litigation Case History,” Dr. Ansell will discuss two phases of the case:  Phase I, liability and divisibility, and Phase II, cost and remedy.

Todd MartinAlso presenting during the INEF meeting is Integral Principal Todd Martin, P.E., who will discuss an investigation involving sample collection and a cutting-edge optical monitoring technique used to characterize PCBs and mercury fate and transport in the Berry’s Creek estuary. Part of the Berry’s Creek Study Area Superfund site in New Jersey, the estuary contains more than 1,000 acres of expansive marshes that generate a substantial amount of organic matter, which influences fate and transport of the contaminants of concern.  Data collected from the investigation were evaluated in conjunction with other data sets to understand responses to tidal flows and storm events.  This information, and characterization of the processes influencing fate and transport, was essential to understanding current and future risks posed by the site and to providing a basis for selection of an adaptively managed remedial action.

Dr. Ansell has worked on the Centredale project for nearly 12 years, both as a consulting expert for two law firms and as a consulting expert with Integral Consulting Inc.  He is an organic chemist with more than 20 years of combined experience as a pharmaceutical research chemist and litigation support scientist. His experience in CERCLA cases includes expert report and rebuttal report analysis, as well as chemical fingerprinting for dioxins/furans, evaluation of chemical fate and transport, and analysis of historical chemical manufacturing and waste disposal practices.

Mr. Martin is a professional engineer and a hydrogeochemist.  He has 22 years of experience in the environmental field, specializing in environmental engineering, the transport and fate of inorganic and organic chemicals in the environment, and remediation alternatives analysis. He is adept in the application of geochemical and hydrologic models to assess water quality and quantity, contaminant transport and fate, and the implementation of bench- and pilot-scale studies to demonstrate remedial effectiveness.
