  Occurrence and Migration of PFAS ‘Forever Chemicals’ in Surface Water and Groundwaterkeyboard_arrow_down

  This presentation will consist of several video animations and associated discussion of groundwater and surface water contamination by the recently publicized PFAS chemicals referred to as "forever chemicals".Attendees to the presentation should expect to gain a mental model of how firefighting foam, a major source of PFAS, impacts these water resources.

  Treating Soils In Place – An Alternative to Excavationkeyboard_arrow_down

  This presentation explores recent developments for treating contaminated soil and groundwater in place with the goal of identification of better and lower cost solutions to accomplish your clients’ objectives. 

  The presentation will provide an overview of recent technology including thermal desorption, vapour extraction, pump and treat, bioremediation, chemical reduction or oxidation, surfactant flushing, horizontal wells, sorption and stabilization additives.  The discussion will focus on the pros and cons of these various approaches and how consultants can obtain the necessary information to provide to their clients as part of the remediation option analysis.

  Experience Using Aerial Drones for Pit Lake Water Sampling and Quarterly Monitoring.keyboard_arrow_down

  The successful prediction and management of mine pit lake water quality is best accomplished through routine, frequent water sampling. Typically, sampling is performed using boats, however, boat sampling subjects personnel to multiple health and safety risks. New water sampling techniques using aerial drones eliminate health and safety risks, reduce the cost of sampling, and can also increase the frequency of data acquisition leading to better lake management.The method has been published, approved by some regulators, and applied at over 21 pit lakes in the USA and Canada. This presentation introduces the equipment and methodology, and provides a detailed case study from the Thompson Creek Mine Pit Lake in Idaho, USA from 2018 to 2020.

  Who’s in charge, you or the data? Simple visualization approach to assess remediation performancekeyboard_arrow_down

  Success in remediation is based on the numbers. One of the greatest challenges, especially to alternative remediation methods, is the demonstration of “certainty”. A vast set of numbers in a table format can sometimes be one of the hardest ways to present both the success and limitations of a treatment process.Using simple statistics tools such as box and whiskers, error bars, standard deviations, etc., allows a complex set of data to be visually presented quickly. This is a highly effective method to determine remediation performance over time and also can be very powerful in planning which remediation techniques to employ, or which not to. During the presentation, various sets of data will be used to present ideal remediation situations as well as others that presented challenges. We will also review how data that is collected purposefully and intentionally can get the programs back on track or provide early warning that changes in treatments might be needed.
