In-situ Chemical Reduction for Remediation of Soil Containing Chlorinated Pesticides and Herbicides
Jean Pare, Chemco Inc.
The objective of this presentation is to discuss soil sterilant and will include an overview of chemistry involved in organochlorine pesticides degradation, along with case studies from several completed applications in the United States, Canada and Europe, and cost analysis.
Development of Generic Risk-Based Soil Screening Values for PFAS Protective of Food Consumption and Soil Leaching Exposure Pathways as Applicable to Biosolid Amended Agricultural Lands
Nava Garisto, Elham Arbaban, Shannon Dunn Arcadis Canada Inc.
The objective of this presentation is to share a study to develop risk-based soil screening values for PFAS, protective of human health due to both direct soil contact and food consumption. The SSV can be used as interim values for evaluating monitored soil quality at biosolid amended agricultural lands.
Site-specific Application of Rapid Small-scale Column Test Data in GAC-based Water Treatment System Design for PFAS
Zeeshan Merchant1, Benjamin Kapfenberger1, John Vogan1, Adam Dawe1, Allan Horneman2, Corey Theriault2 1Arcadis Canada Inc. 2Arcadis US
The objective of this presentation is to illustrate how rapid small-scale column tests of GAC can be combined with ion exchange resin performance analyses, to design water treatment systems for PFAS removal.
Bench Scale Studies of In-situ Stabilization of PFAS-Impacted Soils
John Vogan1, Benjamin Kapfenberger1, Adam Dawe1, Vijay Kallur1, David Liles2, David Osguthorpe3, Pamela Cushing4, Marie Goulden4, Ruby Pannell3 1Arcadis Canada Inc. 2Arcadis US 3Public Services and Procurement Canada 4Department of National Defence
The objective of this presentation is to share bench-scale test results of reagents that can be used for in-situ stabilization of PFAS contaminated soils, in the context of studies at other sites.
Matthew MacLennan, Daniel Ng, Patrick Pond, David Hope Pacific Rim Laboratories
The objective of this presentation is to discuss the results of a study that is informing our understanding of how to evaluate the transport of PFAS through soil and the assessment of PFAS bioaccumulation in tissue and food.
Building Confidence in Your PFAS Data – Sample Collection and Validity Considerations
Carol Cheyne, Matt Vanderkooy, Michaye McMaster Geosyntec Consultants
The objective of this presentation is to outline several approaches to address challenges related to field investigation and data interpretation for PFAS-contaminated sites, allowing for development of more robust sampling methods and improvement of our understanding of PFAS data validity.
PFAS Contaminated Sites – Lessons Learned Canadian and International Sites
Jennifer Kirk1, Barbara Hard1, Lesley Tam1, Elham Arbaban1, Adam Dawe1, Ian Ross2, Lynn Kumita3, Chris McRae4 1Arcadis Canada Inc. 2Arcadis UK 3Public Services and Procurement Canada 4Department of National Defence
The objective of this presentation is to highlight the lessons learned from experience completing site investigations, risk assessments and stakeholder involvement when assessing and managing PFAS contaminated sites under the FCSAP program.
PFAS Water Treatment Trials with Granulated Activated Carbon
Francis Galbraith1, Doug McMillan1, Mark Edwards1, Ruby Pennell2, Marie Goulden3 1SNC-Lavalin Inc. 2Public Services and Procurement Canada 3Department of National Defence
The objective of this presentation is to summarize activities to set up a water treatment facility at the CFB Comox firefighting training area and to run various water treatment trials to evaluate treatment performance, inform long term treatment options, and to optimize the treatment approach.
A Discussion of the Pitfalls of a Poorly Constructed Conceptual Site Model and the Implications on Risk Conclusions and Management Objectives – A Case Study Using a Detailed Aquatic Risk Assessment at a Former Military Airport
The objective of this presentation is to present on the importance of developing a robust conceptual site model to ensure that contaminant sources, pathways and routes of exposure are properly characterized and assessed. If this is not properly characterized, this can have significant implications on remediation objectives and risk conclusions.
The future and transportation of PFAS on three bases of the Australian Department of Defence
René Filion, Alice Walker, Jacqui Hallchurch, Mark Clough GHD
The objective of this presentation is to share the importance of developing a robust conceptual site model that takes into consideration the future and transportation of PFAS in the surface water drainage and groundwater runoff on PFAS sites.
