2021 Agenda Details
High Resolution Site Characterization (HRSC) has greatly enhanced our ability to collect large amounts of site characterization data and accurately describe the location and nature of contamination on a site, thus supporting faster and more effective cleanup. Panelists will examine the latest technological advancements of HRSC and the strategies for its application.

Understanding the varied connections between groundwater and surface water is critical to the effective cleanup and management of any contaminated aquatic site. Using examples from the Pacific Northwest, panelists will investigate the complex nature of the groundwater to surface water / sediment pathway including the causes of water quality degradation and contaminant transport.

Expert practitioners will present an informative set of case studies that demonstrate successful groundwater remediation solutions for varied, challenging, and problematic pollutants. Panelists will address site conditions; contaminant characterization; treatment selection process and alternatives; and more.
Case studies will include:
• In Situ Thermal Remediation of Chlorinated Solvents in Groundwater in the Pacific Northwest • Effectiveness of Zero Valent Iron and other Iron-Based Amendments for Remediation of Arsenic in Highly Alkaline Groundwater • Determining Background Groundwater Concentrations at a Complex Site Using Advanced Statistics and Data Visualization

As our understanding of Contaminants of Emerging Concern (CECs) grows, so does the list of associated public health risks, regulatory concerns, and cleanup challenges. Panelists will provide a general discussion about CECs, what defines a CEC, and present recent examples. Each panelist will then identify a CEC, present a brief history of that CEC including its sources, its fate and transport in the environment, the status of analytical testing methods, and discuss its current Federal and Pacific Northwest regulatory status. Presentations will be followed by an open discussion between the panelists and end with Q&A from the audience.

Banned more than forty years ago, PCBs continue to be a persistent contaminant permeating the environment and posing health risks to both humans and wildlife. The challenge with cleaning up PCBs is identifying the sources, particularly in stormwater, groundwater, and sediments. Using case studies, our panel of experts will delve into the challenging and continuously evolving discipline of characterizing (particularly identifying sources) and remediating PCBs.

Molecular genetic tools are now routinely used to comprehensively characterize microbial communities, and to focus in on specific microbial activities, based on our growing understanding of biodegradation capabilities and functional genes. Next generation sequencing can pinpoint changes in microbial communities that occur through the course of in-situ remediation, allowing for optimization and enhancement of remedial technologies. This session will include practitioners working at the forefront of applied molecular testing at contaminated sites.

Environmental, Social, and Governance (ESG) advances a more holistic approach to an organization’s societal impact and assesses the ethics and sustainability of its investments. ESG standards are rapidly gaining traction across a broad range of industry sectors, and the environmental sector is no exception. Panelists will discuss how the ESG movement is driving sustainable investment and creating value for redevelopment in urban settings as well as its effect on permitting, remediation, and long-term restoration of environmental quality.

With creative support from the Washington State Department of Ecology, the Mt. Baker Housing Association is cleaning up and redeveloping five contaminated properties in Seattle’s Mount Baker neighborhood. When complete, the once-contaminated sites will be transformed into a vibrant mixed-use retail and residential neighborhood. Stakeholders will share how this groundbreaking project became a reality, its status, and what we can expect going forward.
