Air and Vapor Sampling Fundamentals


Will Elcoate, Air Practice Lead, Alpha Analytical Laboratories


Vapor Intrusion pathway evaluation is now an integral part of performing a Site Investigation where it is suspected that volatile chemicals and solvents were used in the past. The EPA has finalized their guidance documents: The ITRC has published two VI guidance documents: States have referenced, incorporated or developed their own programs for VI investigations. Maryland, DC and Virginia have VI guidance with differing approaches. This one-hour presentation, including time for questions, will give cover the basics when collecting Air and Vapor samples to ensure you receive the Data Quality your project requires.

Topics include:

  • Brief review of regulatory guidance both National & Regional

  • What is going on in the DC Metro area? MD, VA & DC

  • Pre-project set up what’s important to tell your laboratory

  • Typical Methods requested for different types of sites

  • Use of media, field sampling quality checks

  • Usability evaluation for collected Data.

A goal of a VI field investigation is to collect representative and usable Data. The purpose of the presentation is to assist in avoiding some of the common pitfalls the laboratory sees when this data is collected.
