Program Summary:

Presented by:

Dogus Meric, Geosyntec Consultants

Session Description:

This presentation will provide an overview of applications, benefits, and limitations of few simple yet well-established and scientifically defensible forensic methods that can reveal trends and additional information hidden in the existing field data; these methods include:

  • Fingerprint analysis (chromatography signatures; stable isotopes; co-contaminants; mass ratios) – to identify and/or distinguish sources and origins of constituents of concern;
  • Statistical methods (principal component analysis; polytopic vector analysis; advanced pattern recognition methods) – to find a perspective that tells the most information about the spatial and temporal relationships in the field data;
  • Geochronology (radioisotope analysis; chemical horizons) – to identify the age of contamination; and
  • Hindcast model simulations (contaminant fate and transport modeling) – to recreate and simulate historical conditions, discharges from different sources, and evaluate the contribution and spatial extent of contamination in different reaches of the system.

By using these tools in harmony along with the Site historical information (i.e., aerial images, insurance maps, historical practice documents), a more informed and nuanced understanding of many contaminated sites have been provided. Recent case studies will be presented where these forensic methods have been used to reduce a PRP’s financial liability through various mechanisms including generating multiple lines of evidence to support legal strategies, identifying previously undistinguishable sources of contamination, and investigating the validity of claims provided by other parties.

Dogus is a project environmental engineer based in the Midwest with 9 years of experience in environmental consulting, remediation and engineering services. He has strong experience in hazardous waste site cleanup projects with a focus on forensics analysis, litigation support, cost recovery, toxic tort cases, chemical fate and transport modeling, sediment transport modeling, surface water quality modeling, remedial investigation, remedial design, and feasibility study. He has served in key roles in many of the nation’s highest-visibility sites.

Dogus is a recognized professional in the liability management and cost recovery for contaminated sediment sites. He provided subject matter expert services for a $100M sediment cleanup litigation case. He is a member of the Wisconsin DNR Contaminated Sediments External Advisory Group and the ASTM International sediment corrective action task force. He has authored standard guidance documents for ASTM on sediment corrective action objectives and the use of environmental forensics. Dogus was an invited guest lecturer at Northeastern University (Boston, MA) in 2017 and presented “Few Forensics Methods that Helped Achieve Equitable Allocation Outcome in Cleanup Projects”. Additionally, he has authored numerous peer reviewed journal articles and presented his work in various national and international conferences and has a patent on a green remediation technology.
