The Essential Role of QA/QC in Vapor Barrier Installations
Date: Thursday, December 5th, 2024
Time: 11am pacific / 2pm eastern
In this webinar Ryan Miller, Director of Land Science, presents top reasons why an effective QA/QC process is essential in vapor barrier installations. QA/QC measures are pivotal to the success of a contaminant vapor intrusion mitigation (VIM) system’s installation to ensure long-term success. There are crucial reasons why implementing QA/QC measures before, during, and after the contaminant vapor barrier installation helps guarantee the efficacy of these systems designed to effectively protect indoor air quality for building occupants. Neglecting a QA/QC plan can lead to significant repercussions, including wasted time, financial losses, property liability increased risk and the underperformance of the contaminant vapor barrier mitigation system.
In this webinar, you will learn:
- Best practices for QA/QC
- Thorough overview on effective contaminant vapor barrier installation process through the lens of QA/QC
- Why durability and constructability of a contaminant vapor barrier system is so important
- Expert tips and insights gathered from experienced vapor barrier installation professionals

Risk and Liability – Part 2: Vapor Intrusion Mitigation and Managing Liabilities
This webinar is the second in a two-part webinar series featuring Eric Leitz, Director of Legacy Site Services at RPS Group. His presentation discussed risk and managing liabilities, taking a look at vapor intrusion. He was joined by Ryan Miller, East Region Manager at Land Science.
Part 2: Risk and Liability – Vapor Intrusion Mitigation and Managing Liabilities
- Similar to PFAS as an “emerging contaminant,” VI was an “emerging pathway” in the early to mid-2000s
- What have we learned since: a patchwork of state regulations
- For transactions and industry, the driver is exposure risk rather than liability and specific regulations
- VI risk evaluation is still evolving (TCE, maybe PFAS?)
- Immediate investigation/mitigation can facilitate operations or transactions, but mitigation must also endure 5-10+ years to provide long-term viability
When suspected or known VI risk is identified at a site, liability can be managed through well-established assessment and mitigation options. However, transactional work often necessitates an accelerated plan for liability management, where a pragmatic approach is needed to quickly analyze VI liabilities and quantify potential risks and consequences. VI risk to the exposed population (e.g., facility personnel and/or the public) is typically the main driver. Given these factors, VI liability estimates can be generated to not only guide the transaction process, but also manage the liability post-close and into the future.

Air Data Quality Control: A Case Study
In this webinar we were pleased to have special guest speaker Sigrida Reinis, PhD, PE, Senior Associate at Langan Engineering and Environmental Services Inc. Her presentation discussed a case study in air quality data control. She was joined by Hieu Nguyen, Principal Engineer at Land Science, who discussed innovative vapor intrusion mitigation system technologies.
Learn the following in this free webinar:
-
- Issues surrounding detectable levels of contamination that can adversely affect data quality due to SUMMA canisters
- A vapor intrusion mitigation system (VIMS) case study where inexplicable anomalies were observed in the monitoring data set
- A numerical approach presented identifying anomalous data developed by Langan to address this problem
In recent years, both anecdotal evidence and rigorous research have indicated that even individually certified SUMMA canisters may arrive at a project site with detectable levels of contamination that can adversely affect data quality. Research (by others) indicates that while approximately three percent of duplicate groundwater samples have laboratory analytical results that differ significantly from those of the primary sample, with whole air samples this inconsistency increases ten-fold. This presentation will focus on one site in the San Francisco Bay Area at which a passive sub-slab vapor intrusion mitigation system (VIMS) was installed during construction and whole air sampling, for the purposes of VIMS performance monitoring, began in the fall of 2016. After several years of regular monitoring, inexplicable anomalies were observed in the data set, and the frequency of anomalies increased over subsequent monitoring events. In response, Langan developed a numerical approach to identify anomalous data that was subsequently applied to the data sets. This presentation will provide a brief project background, describe the QC approach, discuss the ramifications to the project of the data anomalies and their identification, and describe the changes to the sampling program that will be implemented in the immediate future.
