Exponent Webinar Series

Historical Reconstruction of Contaminant Releases:
What are the strengths and weaknesses of various techniques?

Expert opinions regarding the history of chemical releases at a site are often critical in judication of environmental liability. Experts use many different tools to reconstruct historical releases of contaminants and often arrive at opposing interpretations. 

This webinar will provide an overview of the strengths and weaknesses of a variety of methods with an emphasis on case studies.  Some of the topics that will be discussed are document mining, historical process engineering research, aerial photogrammetry and remote sensing, interpretation of fire insurance maps, sediment core dating, and dendrochronology.  A variety of case studies will be covered including mine sites, smelters, former manufactured gas plants, oil spills, oil refineries, dry cleaners, other manufacturing plants, and shipyards. 

The webinar will feature three of Exponent's consultants who routinely practice in historical reconstruction of contaminated sites. We look forward to you joining us!
