HMSC Research Seminar-Is Remediation Worth It?: The Potential for Remediation to Make Soils and Waterways More Toxic

Speaker: Staci Simonich, Associate Vice President for Research Operations & Integrity, Professor of Chemistry and Environmental & Molecular Toxicology, Oregon State University

Topic: Is Remediation Worth It?:  The Potential for Remediation to Make Soils and Waterways More Toxic

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants formed through the incomplete combustion of organic matter. Their hydrophobic nature and persistence can ultimately lead to their accumulation in soils, particularly at industrial sites where direct contamination occurs. Many PAHs are known or suspected human carcinogens and, as a result, 16 parent (unsubstituted) PAHs have been classified as ‘priority’ pollutants.  There are many PAH contaminated sites throughout the world and the clean-up process is complex, from preliminary assessment and site investigation to site reuse and redevelopment, and can use any number of remediation strategies (or combinations of strategies), depending on the level of contamination, the compounds involved, and site characteristics.  Our laboratory has focused on predicting the formation, measuring the presence, and determining the toxicity of PAH transformation products during bioremediation and thermal treatment of PAH contaminated Superfund site soils.  The goal of our research is to provide guidance to site managers regarding the use of appropriate remediation strategies to minimize the formation of these hazardous breakdown products.  Our research address the question, “Is remediation of PAH contaminate soils worth it?”
