Course Description:

The course will discuss current CT DEEP regulations and guidance and includes considerations for appropriate site investigation, laboratory methods and data evaluation, and field sampling techniques and field quality control to meet CT DEEP requirements for assessment of the vapor intrusion pathway. There will also be a hands-on demonstration of the Vapor Pin field instrumentation and best practices for field sampling.

CT DEEP Soil Vapor Sampling - Investigation/RSR Compliance, Carl H. Gruszczak, Jr., CT DEEP

  • CT DEEP expectations when collecting representative soil vapor samples (concurrence with ITRC VI Guidance)
  • RSR applicability (specifically how soil vapor is an alternative demonstration of compliance for and how indoor air could be used for an exemption from the groundwater volatilization criteria)
  • Using soil vapor sampling to select sub-slab soil sampling locations (possible pitfalls)

Site Investigation and Field Sampling, Catherine Regan, ERM

  • Basics for performing a Vapor Intrusion Investigation.
  • Development of a Conceptual Site Model. Multiple lines of evidence.
  • Pre-Project planning. What to look for when setting up to sample. Types of samples.
  • Building surveys.
  • Project data quality objectives (DQOs).

  • Laboratory analytical method selection.
  • Overview of laboratory requirements to report data to meet CT regulatory requirements and reporting limits.
  • Regulatory criteria. Importance of documentation.
  • Sampling methods and use of media. Hands on setup and use of TO-15 media canisters. Role of field meters in investigation.
  • Best practices to address common field issues.
  • Video demonstrations.

Vapor Probe Selection, Sub-slab Sampling Applications, Pre-sampling and Field Integrity Checks, and Video Demonstrations, Craig Cox and Laurie Chilcote, Cox-Colvin & Associates, Inc.

  • Types of vapor probes and their uses, temporary, permanent and abandonment.
  • Sampling probe installation. Sample point selection Do's & Don'ts.
