Soil vapor studies are experiencing a resurgence in popularity with the increased focus on the Vapor Intrusion pathway and the introduction of new tools and analytical methods.  In this presentation we will discuss why understanding a site's soil vapor conditions is so important, how to collect and interpret soil vapor data, and how to use this information for site characterization, conceptual site model development, vapor intrusion assessment, and vapor mitigation.  Throughout the presentation we will present case studies based on sites where the understanding of the soil vapor conditions have helped to streamline the investigation and remediation processes leading to more successful outcomes.    

Sampling events for site investigations require careful planning to ensure the data collected will yield conclusive results.  Consultants and field teams understand their equipment and preparation are critical to human health risk determination. Are all sampling media created equal? Are they all “good enough”?  Data quality objectives provide direction for active vs passive sampling and there are several types of media within these two main categories. Dive deep into side-by-side comparisons of which work best and provide accurate results in a variety of situations. Understand what to consider for your next field event.
