July 2021 Land Science Newsletter

With more than 35 years of experience in the vapor intrusion industry, Tom Hatton, Chief Executive Officer of Clean Vapor, LLC, an innovative mitigation technologies company and valued Land Science® client, has enjoyed great success, knowing the impact that vapor intrusion mitigation can have on the environment. He shares, “This work is my passion. Having the benefit of watching this industry grow — from its inception to its current state of critical importance — has been rewarding. For me, vapor intrusion is more than just environmental science and buildings- it’s a calling to protect human health by providing cleaner indoor air environments.” Hatton co-founded Clean Vapor and has led the N.J.-based firm for the past 15 years. Prior to forming the company, he spent 20 years developing and implementing vapor intrusion mitigation solutions for residential and commercial clients.

Featured Case Study: Cross-Team Collaboration Moves New Public Library and Town Hall Complex Forward

A growing community near Charlotte, North Carolina was seeking a site to construct a new town hall and public library complex. SUMMIT Engineering, Laboratory & Testing, P.C. (SUMMIT) conducted an environmental assessment at the property in April 2020, confirming that petroleum hydrocarbon (PHC) contamination was present. SUMMIT recommended installing a vapor intrusion mitigation system (VIMS) to the property development team, knowing it would be the most effective approach to address PHC contaminant vapors. In considering their options, Nitra-Seal, a state-of-the-art VIMS offering proven chemical resistance and vapor intrusion protection, was selected by the development team.

Introducing a New Advanced Nitrile Composite Vapor Barrier System

Nitra-Seal is an update/improvement on current vapor barrier systems. Originally, passive vapor barrier systems were waterproofing systems adapted for use as contaminant vapor barriers. An acknowledged weakness in these systems is in the penetration and perimeter termination locations, where spray-applied core material composed of Styrene-Butadiene (SBR)- modified asphalt is used. While excellent at repelling water, aggressive chemicals such as petroleum solvents and chlorinated volatile organic compounds (VOCs), will permeate into the SBR-modified asphalt at a relatively high rate particularly in sensitive areas of the building construction such as barrier seams, slab penetrations and perimeters. Nitra-Seal offers a substantial upgrade as it employs a more chemically resistant nitrile latex instead of the more susceptible SBR material. Nitrile is recognized throughout the environmental engineering industry as being more chemically resistant than rubber or SBR and is often used in personal protective equipment when working on hazardous waste sites (e.g. nitrile gloves).

Recording Now Available: Special Land Science Webinar Featured in Europe

REGENESIS is pleased to announce a special vapor intrusion webinar with guest speakers Blayne Hartman of Hartman Environmental Geoscience (USA) and Tom Wuyts, team manager at Terra Engineering & Consultancy, part of Group Van Vooren NV (Belgium). In this live European webinar, Blayne and Tom discuss the challenges of vapor intrusion assessments and the benefits of continuous monitoring. They are joined by Rick Gillespie, Senior Vice President of Land Science, the vapor mitigation division of REGENESIS.

With vapor intrusion assessments, typically only a few contaminant concentration measurements are made, so it is often difficult to reach a conclusion if the vapor intrusion pathway is a concern. The result is that vapor intrusion investigations can drag on for months to years before a conclusion can be reached regarding the potential risk. Such time periods are unacceptable if there is a potential risk to human health.
