Using Passive Sampling as a Decision Making Tool

Thursday, March 1, 2018 - 1:30 P.M. EST

About this webinar:

Passive sampling devices (PSDs) present many advantages over conventional sample collection methods for quantifying hydrophobic organic compound (HOC) availability in sediment, soil, surface water, and stormwater in terms of cost and data applicability.  PSDs provide data to estimate contaminant availability to environmental receptors that is more accurate than conventional grab or mechanically-extracted samples, as it quantifies freely-dissolved contaminants.  In the field, PSDs enable collection of representative and depth-discrete data without the need to collect large volume aqueous samples. Similarly, in laboratory treatability studies PSDs help to decrease the volume and number of samples required to evaluate remedial options for contaminated sediments or soils.

This presentation will highlight examples where PSDs have been used in the laboratory and in the field to collect relevant information to make decisions on site investigation and remediation, as well as additional techniques and advancements to simplify and improve sampling, lower costs, and expand the class of compounds analyzed to include polycyclic aromatic hydrocarbons (PAHs), pesticides and metals using peepers.  In terms of site investigation, we will demonstrate how we have developed and field-tested a diverless sampler deployment and retrieval system at an active waterway site, saving costs and time deploying divers to the site to locate and retrieve PSDs. Additionally, unique project setup considerations specific to PSD analysis will be discussed.

Although passive sampling tools and new approaches to effectively apply them will continue to be refined and improved in coming years, it is clear that currently-available approaches are ready for widespread application and can provide high-quality data to aid environmental decision makers.  To this end, this presentation will also highlight the growing regulatory support for the approach.  For example, in 2017, USEPA released a user’s manual for laboratory, field and analytical procedures for using passive sampling in the evaluation of contaminated sediments, as well as guidance on the application of using porewater data generated by passive sampling to develop sediment remediation goals at Superfund sites.  It is clear that passive sampling technology is mature and ready for application, and will aid in a more effective understanding and management of site-specific investigations.

Topics Presented:

  • General overview of PSDs
  • Current regulatory support for PSDs
  • Current matrices  & deployment systems for PSDs
  • Analytical support for PSDs
  • Summary of the current  ‘state of affairs’ in using PSDs

Who Should Attend?

  • Consulting and Engineering firms
  • Industry Representatives
  • Regulatory Officials
  • Data Validators

A question and answer session will immediately follow the presentation. At the conclusion of each webinar, you will be asked for your feedback and opinions for future webinar topics to be developed by TestAmerica.
