GEI’s Derek Tomlinson & Mike Hawthorne to Present at the Battelle Bioremediation Symposium 5/22-5/25

GEI’s Derek Tomlinson, P.E., P.Eng., BCEE, and Mike Hawthorne, P.G. will be active attendees at the Fourth International Symposium on Bioremediation and Sustainable Environmental Technologies Symposium held in Miami, Florida from May 22-25. The Symposium, consisting of more than 500 platform and poster presentations, will present information on advances in bioremediation and the incorporation of green and sustainable remediation (GSR) practices in a series of technology-focused sessions.

Derek will be chairing Session B6: LNAPL Mobility, Transmissivity, and Recoverability, which will be held on May 24 from 11:20am to 1pm.

Mike is presenting a talk titled “You Get What You Measure: Emerging Concepts and Philosophies for the Quantification, Interpretation, and Application of LNAPL Transmissivity”, on May 24 from 11:45am to 12:10pm, and he is a co-author of a  presentation titled “Era of the BioGeoPhysioChemoHydrogeologist Is Now:  Integration of Disparate Lines of Evidence to Craft Robust LNAPL Conceptual Site Models in Support of LNAPL Remedies”, on May 24 from 11:20am to 11:45am. In addition, Mike’s poster titled “Single-Day LNAPL Transmissivity Measurement through Improved Efficiency Baildown Testing” will be on display during the poster session on May 23 from 5:45pm to 7pm.

About Derek Tomlinson:

Derek Tomlinson is a Principal and Science, Engineering and Technology Leader with GEI based in their Philadelphia area office, with more than 20 years of experience, specializing in development of strategies for managing non-aqueous phase liquids (NAPLs). His graduate training at the University of Waterloo focused on characterization and remediation of NAPLs using high-resolution characterization techniques to understand multi-phase fluid transport within the subsurface. Derek’s technical expertise includes development of innovative site characterization methods for refinement of robust CSMs, which he has used in proper design, implementation, and operation of a range of in situ remediation technologies within both porous media and fractured bedrock geologic settings. He has worked at various types of sites under USEPA CERCLA and RCRA programs, nationally in several state and regional led voluntary programs, and internationally. In addition, he has provided expert witness and testimony in matters related to NAPL releases.

About Mike Hawthorne:

Mike Hawthorne is a Principal Consultant and Vice President and the National Oil & Gas Team Leader for GEI specializing in non-aqueous phase liquid (NAPL) multiphase characterization and risk-based remediation science and technical issues.  He is based out of GEI’s Fort Worth, Texas office, and works nationally on advocacy, research and training initiatives in addition to site characterization and remediation. He has over 29 years of broad-based environmental experience ranging from site characterization to risk-based remediation to compliance and enforcement support to litigation support that includes performance as a fact witness at multiple sites and both as a consulting and testifying expert in litigation.
