    Innovative Investigation Techniques below the Fraser River at a Former Wood Treatment Facilitykeyboard_arrow_down

    This talk will give an overview of innovative investigation techniques that were used in the intertidal and subtidal zones of the Fraser River in support of a monitored natural attenuation remedial option at a former wood treatment facility. In order to characterize the groundwater quality below the Fraser River, multi-level monitoring wells were installed below the high water mark. The groundwater discharge zone was identified and characterized in partnership with a research program at UBC by means of offshore profiling from a boat. Multiple rounds of sampling were conducted to delineate fresh and saline groundwater, helping to establish inferred groundwater flow paths and discharge zones to the Fraser River.

    The Importance & Value of Conducting Detailed Habitat Assessments to Support Ecological Risk Assessments and Remediationkeyboard_arrow_down

    This talk is intended to provide an overview of applicable legislation relating to wildlife, species-at-risk and fish/fish habitat protection and the importance of conducting a thorough evaluation of habitats and habitats supporting fish and wildlife as it relates to information supporting ecological risk assessments and remediation activities. Proper habitat assessments are integral in confirming receptor groups, species interactions, species utilization by resident and seasonal / migratory species, potential impacts and project limitations as well as timing windows and constraints for species occupying sites and surrounding areas.

    PFAS in the Environment – Sources, Behaviour and Remediation at Infrastructure, Manufacturing, and Waste Siteskeyboard_arrow_down

      PFAS, or per- and polyfluoroalkyl substances, refer to a class of synthetic organic chemicals that are of environmental and human health concern in soil and water at exceedingly low, parts per trillion concentrations, are bioaccumulative, and can persist for decades in the environment.   They have been widely used in many products, processes and sectors of the economy - their presence has been well documented at airports, military bases, manufacturing plants and solid waste facilities, among others.  The types of PFAS used and found in the environment can vary considerably among these different sectors, and the release mechanisms can also vary widely.  Consequently, their fate and transport through the subsurface can be challenging to decipher.  Site management and remediation options must be tailored to address the specific chemical conditions presented by the PFAS type within the hydrogeologic and geochemical environment.   In this three-part series, you will learn about the similarities and differences among PFAS sources and environmental impacts in the infrastructure, manufacturing and waste sectors of our economy.  Through case studies, you will see how site-specific characteristics and PFAS analytical data interpretation can be used to successfully characterize and differentiate PFAS sources and plumes. You will gain insights on site management and remediation decision-making in response to the type and extent of PFAS impacts, the presence of co-contaminants, and complex environmental matrices. This three-part webinar series on PFAS will cover the following areas:

    • Critical considerations and insights about PFAS investigations
    • International regulations and the Canadian federal contaminated sites perspective
    • PFAS uses and sources in the infrastructure, manufacturing and waste sectors
    • Source and plume characterization and differentiation
    • Case Studies - Effective site characterization strategies and best practice
    Organized around 3 one-hour sessions:
    • Session 1:        Tuesday January 15th (9-10 AM PST / 12-1 PM EST)
    • Session 2:        Tuesday January 22nd (9-10 AM PST / 12-1 PM EST)
    • Session 3:        Tuesday January 29th (9-10 AM PST / 12-1 PM EST)
    Session 1 is FREE, and will be led by representatives from Environment and Climate Change Canada and Health Canada.  Remaining sessions will be led by an experienced PFAS team from Golder. Link to first session: Link to all three parts:

    Session 1 - Representatives from Environment and Climate Change Canada and Health Canada; Sessions 2 & 3 - experienced PFAS team from Golder
