Passive Samplers for Sediment & Water for PCBs, OC Pesticides, Metals and other Inorganic Analytes

Tuesday, October 22 - 1:30 P.M. EDT

About This Webinar:

Passive sampling devices (PSDs) present numerous advantages over conventional sample collection methods for quantifying hydrophobic organic compound (HOC) availability in sediment, soil, surface water and storm water. PSDs can provide superior convenience, cost and data quality compared to conventional grab or mechanically extracted samples. A major advantage of PSDs is their property of quantifying only the freely dissolved, bioavailable, fraction while not measuring the sorbed, or non-bioavailable fraction. Measuring only bioavailable contaminants with PSDs provides a better measure of actual toxicity and mobility for environmental receptors and a lower tendency towards toxicity overestimation than conventional sampling methods.

This presentation will highlight examples where PSDs have been used in the laboratory and in the field for decision making in site investigation and remediation, including techniques and advancements that simplify and improve ease of sampling, increase data quality and lower costs. We will demonstrate how a combination of an in-situ application of peepers as PSD to analyze sediment porewater mobility of heavy metals and ex-situ testing with polyethylene PSDs for polychlorinated biphenyl (PCB) and organochlorine pesticide (OCP) porewater concentrations was applied to site investigation.

The presentation will also provide updates on diverless deployment methods for PSDs used in waterways and how they can be used to improve sample deployment and retrieval. Further advances to deep sediment sampling will also be showcased, demonstrating how a single sampler can be divided into smaller segments to represent discreet depths in the field. These advances continue to demonstrate that passive sampling is a mature technology that has a variety of applications that continues to expand.

Topics the Presentation Will Cover Include:

  • 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 Eurofins TestAmerica.
