Toxicity of petroleum and the degradation of petroleum products in the environment continue to be a central topic. And the understanding of petroleum toxicology continues to evolve, along with new methods for measuring residual contamination. New technologies and methodologies are emerging to measure and treat petroleum and traditional methods continue to be improved. Case studies and discussions will highlight strategies to manage petroleum clean-up sites and emerging research into the potential toxicity of petroleum degradation metabolites.

Expert practitioners will share practical examples covering a detailed range of in-situ technologies for groundwater remediation and leading-edge approaches for contaminant mass removal in soils particular to many common recalcitrant compounds. Case studies will include project sites specific to the Pacific Northwest and beyond.

High Resolution Site Characterization (HRSC) has greatly enhanced our ability to accurately describe the location and nature (or absence) of contamination on a site thus supporting faster and more effective cleanup. Panelists will discuss the needs and applications of HRSC and present a case study that demonstrates its effectiveness on a TPH-impacted site.

Per- and polyfluoroalkyl substances (PFAS) pose a significant liability for industry, local, state and federal government and the US Department of Defense. In this session, speakers will provide their perspectives on the management and cleanup of PFAS compounds in soil and water including: an update on the federal regulatory framework; strategies from large industrial/commercial wastewater treatment companies; navigating the myriad of decisions facing business; and field sampling techniques. Understanding and then coupling PFAS management and clean up techniques with appropriate long-term monitoring approaches can provide stakeholders with a cost-effective risk management strategy.

Explore how certain features in highly developed areas vary from our textbook predictions for expected behavior of contaminants and contaminant migration in the subsurface. Panelists will discuss reasonable considerations for characterization of a site that may be influenced by modern urban features and/or comingled or concentrated cleanup sites.

Panelists will address the complex issues faced during the construction phase of returning a contaminated to property to productive use, and how consultants and contractors are dealing with them – especially when simple answers and guidelines are not apparent.

Exposure limits from vapor-forming chemicals such as trichloroethylene and benzene have raised concerns about Vapor Intrusion (VI) and its impact on project requirements. Examine the latest investigation and mitigation techniques in this evolving discipline and how to address different attenuation factors and their influence on investigative techniques and methodologies.

Through the medium of role play, panelists will explore real world examples of how attorneys and consultants can foster partnerships and effectively work together throughout the various stages of managing a contaminated site. A hypothetical PCE-contaminated site will support scenarios involving the purchase of the property and subsequent litigation.

Join Department of Ecology for a policy update followed by an interactive listening session. Topics will include: Cleanup Rule Update; Sediment Policy; Implementation of Substitute House Bill 1290 which gives Ecology the authority to expedite reviews of contaminated property cleanups under the Voluntary Cleanup Program and waive review costs when properties are redeveloped for affordable housing; and other hot topics.
