This webinar will introduce the use of passive samplers to assess bioavailability and the development of Porewater Remediation Goals (PWRG). Passive sampling devices (PSD) are a technology with growing acceptance for measuring porewater concentrations and assessing bioavailability of contaminants in sediment, particularly for common sediment contaminants such as PCBs, PAHs, chlorinated pesticides and dioxin-like compounds. Instructors will explain the basics of what passive samplers are and how they work, as well as provide an overview of the deployment, analysis, and application of PSDs. The webinar will also discuss the derivation of Porewater Remediation Goals (PWRG) for the protection of the benthic organisms using exposures measured with PSDs. This section of the course will focus on the application of PSD data to ecological risk assessment, including the application of Final Chronic Values from Ambient Water Quality Criteria, use of PSD in toxicity and bioaccumulation testing, development of a site specific PWRG, and calculation of a sediment RG based on site-specific equilibrium partitioning. Instructors will also discuss the implementation of PWRGs as it relates to risk assessment and management at Superfund sediment sites.

By taking the webinar, participants will achieve the following objectives:

  • Understand how PSD measures bioavailability of contaminants in sediment porewater,
  • Be provided with an overview for planning and executing a PSD sampling event,
  • Understand how to apply PSD data to ecological risk assessment,
  • Learn how to develop a site-specific PWRG to protect the benthic organisms,
  • Consider other uses of PSD methods for RI/FS, remedy selection, and remedy implementation at Superfund sediment sites.

The target audience is EPA Remedial Project Managers and risk assessors, as a well as other regulatory staff, contractors, and responsible parties.
