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.

Client Spotlight: Tom Hatton, Clean Vapor, LLC

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. His extensive experience includes work on over 11,000 sites in the US and abroad, and clearly positions him as an expert in his field. He continues, “One of the things I love most about the vapor intrusion (VI) industry is solving the problem at hand. Every building is different, and designing an effective VI system is as much an art as it is a science. Understanding all of the variables contributing to a VI problem, interpreting the data, and designing the most effective system possible for a specific site makes the work enjoyable.”

Hatton chose the VI field due to what he calls a “natural love” of the sciences, construction engineering, and problem solving, and feels vapor intrusion is the intersection of all three. “What makes it especially rewarding for me,” he says, “Is the outcome- which is the protection of human health. When I complete the design and installation of a vapor intrusion mitigation system (VIMS), along with the integration of the long-term monitoring program, I know the air in that building is healthier and better for the people who occupy that building each and every day.” Hatton’s interest in the environment and sciences began in his youth, and would lead to earning his Bachelor of Science (BS) in Natural Science (a major which combines physics and chemistry) from Bryan College, a private university located in Dayton, TN. He recalls how vapor intrusion was just beginning to emerge early on in his career, and how VI research projects provided an opportunity to creatively blend all three of his passions- chemistry, soil mechanics, and building construction, into one effort. He also discovered how much he enjoys the variety VI projects offered. He continues, “Every building is a unique challenge. Unraveling the mystery of a building leads to continuous learning opportunities, creative solutions for both existing buildings, new construction, and improving the electronic management of those systems. It really is all about enhanced sustainability and keeping future generations safe.”

Hatton enjoys working with Land Science, in part because of the company’s principles. “Land Science appreciates the value and importance of a job well-done.  In an industry that affects human health, Land Science prioritizes quality and efficacy over cost and expediency.” He relates how a recent new construction project in a suburb of Charlotte, North Carolina required the use of an advanced engineered barrier. He continues, “As system designers, Clean Vapor knew that for this project, Land Science offered an ideal solution. By using Nitra-Seal the client was getting a superior value that will last the life of the building and provide decades of protection against vapor intrusion.” He notes that Nitra-Seal® and MonoShield® are used for a variety of applications because they offer the best combination of protective properties, ease of application, long-term durability, and cost. To stay current on new technologies and emerging industry trends, Hatton ensures Clean Vapor is continually engaged in on-going professional development by evaluating new technologies, materials, and products. He shares, “Our team does this on our own and in collaboration with others, in an effort to help us better understand construction practices and on-going process improvements.”

Hatton and his family reside in New Jersey, where he and his wife, have two grown children. His daughter also works in Clean Vapor’s marketing department as a project coordinator. In his free time, Hatton enjoys “anything with wings or motors”. He shares, “I am a pilot and enjoy flying recreationally. I also enjoy restoring antique cars, and convertibles…as long as they’re Fords.  I also enjoy scuba diving, kayaking, and hiking.” When asked what he enjoys most about his work, he responds quickly, “Knowing that Clean Vapor has designed and installed over 11,000 mitigation systems and that our goal of producing results exceeds industry standards which has resulted in the improvement of human health and the saving of lives.” And the most challenging aspect? “I will say it is educating responsible parties about the value of investing in mitigation solutions and persuading them to take action to both protect the building occupants and reduce their long-term liability.”

When asked how he would encourage others to join his field, he points to his industry’s diversity and the multitude of opportunities. He concludes, “Vapor intrusion is a multi-faceted industry that is at the intersection of geology, lab science, consulting, construction, data analytics, electronics and the mechanical trades. There are many growth opportunities in each of these disciplines. The US EPA has characterized the current state of the industry as being in the ‘2nd inning of a nine-inning ball game’, and I would agree with that assessment. A young person could enter this industry right out of school and have an opportunity to shape not only their own career, but that of an industry still in its infancy. The global market is almost unending, which presents nearly endless opportunities for growth and fulfillment.”

Land Science is proud to have Tom Hatton, Chief Executive Officer of Clean Vapor, LLC, as a valued client and partner in environmental remediation, and appreciates his vast experience and exceptional leadership in providing successful remediation and mitigation outcomes for Land Science and its clients.

For Patrick Lowery, Sr. Environmental Manager with SUMMIT Engineering, Laboratory & Testing, Inc., a multi-disciSummit Engineering, Laboratory & Testing, Incplinary environmental consulting firm and valued Land Science® client, a career in environmental remediation was sparked by an interest in geology, a field his grandfather worked in. Lowery initially planned to follow his grandfather’s path and become a geologist, but then realized his true passion involved assisting in the cleanup of our planet. He shares, “My grandfather was a geologist for Shell Oil in the Permian Basin, near Midland Texas.  Throughout college my focus was to work in the petroleum industry.  I took a year off from school after earning my Bachelor of Science in Geology from the University of Alabama and was going to attend Colorado State University for my Masters in Geophysics, however, while working with a consulting geologist that year I found I enjoyed the environmental field.”

Nitra-Seal Applied as Preemptive Vapor Mitigation Solution

 

A growing community near Charlotte, North Carolina was seeking a site to construct a new town hall and public library complex. The city planners had identified a land parcel that would meet the spatial requirements for the new complex, but the site was a former gasoline service station which operated on a portion of the land for nearly two decades. As part of the City’s due diligence, a Phase I Environmental Site Assessment (ESA) was completed and revealed the underground storage tank (UST) system was decommissioned in 1991 with the tanks abandoned in place. However, no records existed which documented environmental conditions at the time of UST removal. Consequently, the USTs were listed as a recognized environmental concern (REC) in the Phase I ESA. In early 2020, a geotechnical investigation identified soil with odors and elevated photoionization detector (PID) readings, a further indication of petroleum hydrocarbon (PHC) contamination in the subsurface.

Featured Project Snapshot: Townhome Residents Protected from Exposure to Vapors

 

Townhome Residents Protected from Exposure to Vapors

 

A townhome development in Greenville, South Carolina, implemented the MonoShield vapor barrier and TerraVent low-profile venting system to address low-level volatiles organic compounds, keeping future tenants safe from exposure. The environmental consultant required a turnkey installation for the barrier and venting system along with quality assurance/ quality control testing of the system. The consultant also evaluated a single-layer polyolefin sheet system that relies on taped seams and is not installed by a certified applicator or smoke tested. In comparing the approaches and costs of the two options, the MonoShield system was selected based on the time-efficient, certified installation in addition to its proven chemical resistance. The installation was completed across the 6,000 square feet foundation in less than two days at a low cost. The consultant, also a certified Land Science Inspector, provided an added layer of quality assurance and value to the developer by overseeing and documenting the installation process.
