Client Spotlight: Mark Quimby, Senior Consultant at SME

Mark Quimby SMEThroughout his 14-year professional career, Mark Quimby, Senior Consultant at SME, a leading regional multi-service engineering and consulting firm and valued Land Science® client, has established himself as a top expert in the field of assessing and mitigating petroleum, chlorinated solvents, and methane vapor intrusion sites. During this time, he has designed and installed dozens of vapor intrusion mitigation approaches inclusive of sub slab passive venting, multiple types of vapor barriers, active sub slab depressurization, and passive interceptor trenches.  In addition, he has secured and managed over $50 million in local, state, and federal incentives that include grants, loans, tax abatements and credits, and tax increment financing. He shares, “Currently, I am responsible for the technical oversight on projects, primarily brownfield redevelopment.  I am also responsible for working with our project managers and staff, and mentoring them as we deliver solutions to our client’s problems.” His vast experience in his specialized area of environmental remediation stems from an impressive career at SME, where he has risen from a Staff Environmental Specialist to a Project Consultant and then to Senior Project Consultant, prior to being promoted to his current position. His career began shortly after graduating from the University of Windsor, Ontario, where he earned his B.S. in Physics, and it has given him a unique appreciation for seeing the results of his efforts. He shares, “So many sites have no viable liable entity, and without the partnership with communities and developers, the cleanup and redevelopment may never happen.  I’ve really enjoyed remediation in this context because I get to participate in both the cleanup and the redevelopment of the site.”

Although his university studies may not have initially correlated with a career in environmental remediation, Quimby now feels fortunate to be working in a profession that makes a measurable and positive impact on our planet. He continues, “I fell into environmental remediation more than I chose it, but it has been a rewarding field and I’m glad I’m here.  My degree is in physics, but when I immigrated to the US from Canada, I was hired by an environmental consulting firm.  Since then, I’ve worked on a wide variety of sites and cleanups but have spent most of my time in the context of Brownfield redevelopment.” When asked what he enjoys most about his day-to-day work, Quimby is quick to point to a keen sense of satisfaction from seeing his efforts come to fruition. “I enjoy helping to revitalize neighborhoods and communities,” he says. “Many communities have vacant and derelict properties that provide little or no value while presenting a nuisance and health risk. It is rewarding to turn these into assets.” And what is the most demanding part of his job? “Definitely the pace,” he says.  “Every day is different and I need to remain flexible to address my client’s needs as they arise.”

When it comes to working with Land Science®, Quimby appreciates the firm’s level of expertise and timely support, and notes that both routinely contribute to enhancing the efficiencies in his work. He continues, “We have worked on several projects with Land Science®. They provide very good technical depth and they are responsive to our support needs.” With regard to specific Land Science® products, MonoShield™ is one that he and SME have recently turned to.  He shares, “We are currently using MonoShield™ for the first time on two projects. One is Liberty Park Commerce Center in Sterling Heights and another is Tri-County Commerce Center in Hazel Park.  MonoShield™ is providing us with the efficiency of a pre-fabricated roll out system and the flexibility of the spray-applied component for seams, penetrations, and transitions.” Quimby adds, “This is allowing us to meet our project goals in less time compared to alternative systems.” In the past, his teams have also used Geo-Seal® with success, and feels both products have the support infrastructure he needs to ensure successful project outcomes. In addition, he appreciates the collaborative benefits from his company’s relationship with Land Science®. He continues, “Land Science® has a reliable network of certified applicators that we have also developed relationships with.  The bottom line is, when working with Land Science®, we know what to expect and have confidence the team will bring the project to a successful conclusion.”

Residing in Plymouth, MI with his wife and four children, Quimby works out of the SME corporate office in Plymouth, and on occasion travels to the firm’s Detroit and Lansing offices. He also supports staff in the other SME offices in MI, IN, and OH. When he’s away from his work, he enjoys reading nonfiction books on science, philosophy, and history, and playing tabletop board and card games.  He shares, “My current favorite reads are the Expeditionary Force series by Craig Alanson.  My favorite card game is Magic the Gathering by Wizards of the Coast, and my favorite board game is Axis and Allies.”  To stay abreast of current trends and the latest technology in his field, he attends various training sessions that include formal classes sponsored by ASTM (American Society for Testing and Materials) and EGLE (Michigan Dept. of Environment, Great Lakes, and Energy).  He’s also taken the Princeton Groundwater pollution and hydrology course. When asked what the future goals are for SME, he points to continued growth within the Midwestern US. He continues, “We will continue to grow in MI and expand our operations in IN and OH.  Our goal is to be the premier engineering consulting firm in the Great Lakes Mega Region.” And what does he see the future holds for environmental remediation? “I feel vapor intrusion mitigation and remediation is the biggest trend.  The country, and Michigan specifically, is trying to get their arms around the Per- and polyfluoroalkyl substances (PFAS) issue as well, but vapor intrusion (VI) will remain a top priority because of its widespread presence and the relevancy of the pathway to human health.” When asked why he feels the work he does is important and why he encourages others to join his field, Quimby speaks to the need for commitment in how we treat our environment. He concludes, “We need to care about the future of our cities and developed areas.  It doesn’t make sense to use up land and walk away.”

Land Science® is proud to have Mark Quimby, Senior Consultant for SME, as a valued client and partner in environmental remediation, and appreciates his expertise and diverse contributions in providing successful remediation outcomes for Land Science® and its clients.

Client Spotlight: Jarrett Baggett, Environmental Services Director for Geo-Hydro Engineers, Inc.

For Jarrett Baggett, Environmental Services Director for Geo-Hydro Engineers, Inc., a leading environmental consulting and engineering firm and valued Land Science® client, growing up on a dairy farm instilled a deep affection for our environment. An affection that ultimately would lead to his professional vocation where he could make a difference on behalf of our planet.  “I loved the outdoors growing up,” Baggett shares. “I knew I needed to choose a career that would allow me to spend time outdoors.  Although I was initially unsure of what I wanted to major in for college, I knew I wanted to do something related to the environment.”  In a career which has seen him advance up the ranks from a Jr. Geologist to Staff Professional, then Project Manager, and finally to his current position as a Director at Geo-Hydro Engineers, Baggett can reflect on his work, and look forward, knowing he is indeed making an impact. He shares, “To see a property go from a dilapidated eyesore that poses potential risks to the community, to a property that can be utilized and enjoyed by all as a result of your hard work is very rewarding.” In his current role with Geo-Hydro Engineers, Baggett is responsible for the Environmental operations at the company, which includes managing environmental projects and maintaining interaction with clients, personnel, and regulatory agencies. He continues, “I oversee a group of engineers, geologists, and environmental scientists performing environmental studies in the industrial, commercial, agricultural, and real estate sectors.  Our clients include owners (private and public), industry, developers, banks, architects, structural engineers, and contractors just to name a few.”

Baggett prepared himself for a career in environmental management by earning his B.S. degree in Geology from the University of Tennessee, Knoxville. He shares, “I took some Geology classes and thoroughly enjoyed them. The coursework, coupled with my love for the environment, soon led to me earning my geology degree.” To stay abreast of trends in his field, he takes continuing education coursework to fulfill requirements for his P.G. license, which he holds in several states. In addition, he attends seminars and conferences to keep up with the latest technologies, standards and regulations that are relevant to the industry. When asked why he enjoys working with Land Science®, he points to the company’s reputation for developing advanced solutions that are capable of addressing today’s environmental challenges. He shares, “Land Science® reached out to us and came by to present some of their tech products and capabilities.  The team was extremely knowledgeable, especially with regard to the vapor intrusion industry.  Seeing a rising need for vapor mitigation in real estate development, I knew it was just a matter of time before we would have the need to apply some of the Land Science® products to our sites.  That need arrived, and we are now placing over 100,000 square feet of GeoSeal® with Vapor-Vent™ at a mixed-use development at a site along the Atlanta Beltline. We looked at several products, but really liked the GeoSeal® product with its combination of HDPE and asphalt/latex layers that provide an effective and durable product for vapor mitigation. Land Science® has been very helpful in making sure the design process, pricing details, and application process went smoothly.”

Residing in Roswell, GA, where he lives with his wife and two children, Baggett primarily works out of his firm’s Kennesaw, GA, office. When asked about the goals of Geo-Hydro Engineers, he quickly points to continued growth. “We have seen substantial growth throughout the company over the past five years,” he says. “We have opened two new offices over the past two years and started a new environmental branch in our Charlotte, NC office this past year. In the near future we are looking to expand our environmental services, add new employees, and continue to grow revenue.” In addition, he recognizes the challenges his work entails, and strives to avoid over-extending himself in an effort to maintain his high quality of work. He shares, “It’s easy to try and take on more and more project work.  But once you over extend yourself your dedication to each project tends to slip.  For me, there’s a constant balance of knowing your limitations, knowing when to hire more personnel, and when to reach out for help.  Although as a company we are always trying to grow and exceed expectations, our ultimate responsibility and duty is to provide quality products to our clients.” Outside of work, Baggett enjoys fishing and spending time with family and friends. He also finds time to work in his yard. He shares, “Although I don’t live on the family farm anymore, I do enjoy working in the yard.  My wife jokes that this is my substitute for not working on a farm anymore, and that I tend to our yard like it’s a farm crop.”

When it comes to how he has seen the industry evolve over the years, Baggett says he’s observed that many developers have changed their views regarding treatment plans of environmentally impacted sites. He’s especially noticed how today’s new technology is making an impact. He shares, “We work with a lot of commercial developers, and over the last five to ten years, we have seen many of these developers change their views on environmentally impacted sites.  They have educated themselves on the latest environmental technologies and programs provided by their states, and are taking advantage of these.  They’re now embracing these sites and working with environmental consultants to remediate and develop properties once thought to be undevelopable.  Another aspect is the advancement in technologies.  For instance, with the vapor intrusion issues that have come to light in the last ten or more years, vapor mitigation products like GeoSeal®, Vapor Vent™, and RetroCoat™ have improved and become more cost effective to install, allowing for more efficient renovations and development of properties.” And how would he encourage others to join in his field of study?  He concludes, “I would first encourage people to find something they enjoy.  No matter what you do, you are going to have to work hard to be successful, so if you enjoy it, it makes working hard a lot easier.  If that something might be environmental work, I would then ask them if they like solving complex problems with innovative ideas and solutions.  If so, then the environmental field may be for you.  As a said before, it is very gratifying to see a project you were a part of become something that can be enjoyed by many.”

REGENESIS and Land Science® is proud to have Jarrett Baggett, Environmental Services Director for Geo-Hydro Engineers, Inc., as a valued client and partner in environmental remediation, and appreciates his dedication and creative approach in providing successful remediation outcomes for REGENESIS and its clients. 

Client Spotlight: Matt Hall, Senior Engineer and Senior Project Manager at Terracon Consultants, Inc.

Matt Hall TerraconFor Matt Hall, Senior Engineer and Senior Project Manager at Terracon Consultants, Inc., a leading environmental consulting and engineering firm and valued REGENESIS client, choosing a career in environmental remediation started with an interest in cleaning up our environment., Once he became immersed in his studies however, he quickly became passionate about the “how-to” aspects that drive the science behind remediation. Shares Hall, “My initial interest soon morphed into a fascination with understanding the science behind the products and the engineering design for remediation implementation.” Eventually, Hall’s commitment to the earth’s environment lead to earning a dual bachelor’s degree from Tulane University in Ecology, Evolution, & Organismal Biology (EEOB), and Environmental Studies.  After graduation, he worked as a staff level professional at an environmental engineering firm and worked his way up the ranks before joining Terracon, seven years ago, where he enjoys a diverse range of responsibilities. He continues, “I manage a wide variety of projects near my home office in Tennessee, but also provide support for vapor related projects across the country.  The national work includes consultation regarding vapor intrusion, design of vapor mitigation systems, and ongoing operations and testing of these systems.” It’s a role Hall enjoys, from both a collaborative and long-term perspective. He continues, “I enjoy the people that I work with, and I continue to take satisfaction from helping Terracon become a national leader in the vapor intrusion and mitigation world.”

Working with Land Science to Solve Vapor Intrusion Challenges

When it comes to working with REGENESIS and its vapor Intrusion division, Land Science, Hall appreciates the company’s vast array of available products and solutions and knowing their solutions have been researched and proven to be successful in the field. “REGENESIS offers a solid stable of products, and they’ve put the resources into testing those products,” shares Hall. “We’ve had a number of occasions where we were trying to iron out grey areas in a spec, and REGENESIS stepped up to provide documentation that saved the day.” While Terracon Consultants, Inc. uses a variety of REGENESIS products, Hall himself is particularly involved with their vapor mitigation products, such as Geo-Seal®, which is marketed under the company’s Land Science® division.  When asked what he considers the best part of his job, Hall points to the day-to-day aspects of providing the most effective solutions for his clients. “I enjoy solving difficult challenges, along with brainstorming and collaborating with some exceptional minds at Terracon.  I also appreciate is the opportunity to mentor younger staff.” It’s this aspect of working with young environmental engineers that Hall feels will help Terracon Consultants, Inc. continue to thrive in the years ahead. He shares, “Terracon’s mission is to deliver success for our employees, clients, and communities.  It’s been awesome to watch each of these materialize over the past several years.” An employee-owned company, Terracon Consultants, Inc. provides environmental, facilities, geotechnical, and materials services throughout the U.S., and includes over 4,000 employees in more than 140 offices, enabling the firm to provide state-of-the-art services in all 50 states. The company is currently ranked 24th on Engineering News-Record’s ENR list of Top 500 Design Firms.

Originally from Tennessee, Hall began his career while living in the San Francisco Bay Area, before relocating back to Tennessee to join Terracon Consultants, Inc.  He lives in Nashville, and as one might guess, loves music, especially live music. He continues, “I’m a big fan of music, and I’m active in the rock and pop scene here in Nashville.  And yes, there is a lot more than just country music in Nashville!  I’m also an avid homebrewer, and probably spend more weekends than I should tinkering with brewing and fermentation equipment.”  To stay current in his field of study, Hall regularly attends company-sponsored events through Terracon Consultants, Inc., which often includes panel or roundtable discussions. He shares, “We have practice resource groups (PRGs) within Terracon, which consist of some of our top engineers and geologists in specific sectors of the environmental practice.  I chair the Vapor PRG, and am a member of the Remediation PRG.  These meetings are often a forum where we share new information that we may have learned from conferences, presentations, publications, webinars, regulators, or the “school of hard knocks”, from our own unique experiences.”

The Future of Remediation and Vapor Intrusion Technologies

When asked what he sees for the future of environmental remediation, Hall feels the burden of culpability and accountability within the industry may be casting a long shadow. “I’m concerned that it is going to be less about science, and more about liability protection in the future.  It’s also going to be very interesting to see how the emerging contaminants today (PFAS, PFOA) play out in the municipal water supplies.  Something that prevalent in our society is going to be hard to clean up to the levels that the risk-based models are generating.” He also feels the industry will need to adapt to new pollutants and toxins in the future. “I’ll be watching to see what happens with emerging contaminants in the coming years, and how the industry as a whole addresses it.  From a soil and groundwater perspective, I think we’re going to start to see more risk-based closures with land use restrictions, including vapor mitigation systems.  From a vapor perspective, I think we are going to see more innovation in the testing, operations and maintenance side of mitigation systems.” And what suggestions would he have for those considering a career in his industry? “Find a good mentor and really listen to them.  There are few out there that have taught me immeasurable amounts just from having the opportunity to work with them. Listening is key. I’d also suggest a dose of humility with clients.  I’ve seen too many of my peers try to tell the client what they need, when oftentimes the client is calling to tell you what they need. And lastly, you’ve got to love to learn, and learn from every failure.  We often work in an environment where we can’t see what’s below the ground, so things are going to happen that you don’t expect.  It takes time to build up a repertoire of enough failures to make you a great remediation engineer.”

REGENESIS is proud to have Matt Hall, Senior Engineer and Senior Project Manager at Terracon Consultants, Inc., as a valued client and partner in environmental remediation, and appreciates his wealth of knowledge and diverse contributions in making a difference in successful remediation outcomes for REGENESIS and its clients.

When to Use Continuous Monitoring to Resolve Vapor Intrusion Challenges

Several common questions arise when investigating a site for potential vapor intrusion related challenges. Often it is difficult to discern whether vapor intrusion is occurring and if so, where it is entering the building. Additionally, it is important to be able to identify the composition of intruding vapors, because certain harmful vapors such as trichloroethylene (TCE) require immediate action to minimize health risks and associated liabilities. Once vapor intrusion is discovered and mitigation ensues, an added concern is whether or not the mitigation achieved key risk reduction objectives or actually increased potential exposures. In the past, each of these concerns has been difficult to address with traditional canister and sorbent sample monitoring methods because of their propensity for false positive and false negative conclusions and insufficient sampling resolution in dynamic settings. However, technological developments over the past decade have rendered continuous monitoring platforms viable and cost-effective solutions capable of addressing each of these concerns.

Vapor intrusion mitigation
At this site, Retro Coat™ Vapor Intrusion Coating was implemented to mitigate risk of vapor intrusion.

VaporSafeTM, an automated laboratory grade analytical and reporting solution developed by Groundswell Technologies and Hartman Environmental Geoscience, is a near real-time continuous vapor monitoring and response platform capable of tracking chemical concentrations from up to 30 locations as far as 300m from the instrument. This system is used to assess whether vapor intrusion is an issue, determine the vapor composition, distinguish between indoor sources and vapor intrusion, and to quickly identify vapor entry locations. VaporSafe is particularly useful for sites experiencing trichloroethylene (TCE) vapor intrusion concerns because these sites require rapid response to minimize health risks and associated liabilities. Unlike traditional monitoring methods, VaporSafe responds to acute TCE risks within minutes – well before an exposure duration of concern has transpired.

VaporSafe is particularly useful for sites experiencing trichloroethylene (TCE) vapor intrusion concerns

The VaporSafe data patterns enable rapid resolution and advancement to the next step in the site management process. As such, this technology can be integrated into projects during several phases: during initial screening and due diligence efforts; when monitoring to confirm no risk; to rapidly identify vapor entry points; to distinguish between indoor sources and vapor intrusion; to optimize mitigation systems; and to prevent current and future exposures through automated response. Because this technology produces key patterns and correlations within hours, it is also useful for efficiently resolving questions during escrow for property transactions and Brownfield redevelopment efforts. VaporSafe makes it possible to anticipate and correct problems before concentration levels become acute – saving time, money and energy. For more information, go to groundswelltech.com/VaporSafe.

Vapor Intrusion Characterization and Management Solutions: The Case for Continuous Monitoring

Vapor intrusion is challenging to characterize for a multitude of reasons. For example, many cases involve indoor background sources, preferential subsurface migration pathways, shallow subsurface and indoor concentration dynamics, or limitations associated with manual monitoring. Typically, canisters and passive diffusion samplers are used to measure and monitor potential vapor intrusion exposures. Unfortunately, these types of samplers don’t provide sufficient temporal or spatial resolution in dynamic settings. As a result, this method has a propensity to yield false-negative and false-positive results. In addition, the time required to obtain a result is longer than the acute TCE exposure duration of concern, so these options can result in unhealthy exposures and liabilities.

Thanks to technological advances, continuous monitoring platforms are now being used to characterize and monitor vapor intrusion. These platforms are made of multiplexed lab grade analytical components with quality control features to automatically generate geospatial time stamped renderings and time weighted averages through a cloud-based management platform. Continuous monitoring platforms provide auto alerts and responses within one minute of the threshold exceedance detection. Further, these platforms provide superior temporal and spatial resolution based on high frequency repeat analyses from strategic monitoring locations, resulting in an optimized remediation design and unequivocal mitigation system performance confirmation. Blower and HVAC controls can also be engaged automatically when needed.

Continuous vapor intrusion monitoring
Continuous monitoring platforms provide auto alerts and responses within one minute of a contaminant vapor exceedance detection

Until a few years ago, cost and instrumentation limitations rendered continuous monitoring systems impractical. Automation and multiplexing now make it possible to perform rapid, cost-effective and continuous assessment and response with a single instrument. For example, a cost comparison analysis of a series of common monitoring scenarios showed that continuous monitoring platforms were cost-competitive when 5 or more locations were being monitored (read the full article here). Automated response capabilities also provide for acute TCE risk prevention, which is not possible with any other monitoring method.

Regulatory support for these platforms has enabled property owners and their consultants to more accurately address potential liabilities, reduce unnecessary remediation costs, produce more effective and surgical remediation strategies, and allow practitioners to most effectively evaluate remediation system performance. More specifically, continuous monitoring allows practitioners to quickly (within a day or two) determine whether vapor intrusion is an issue, and if so, to identify the vapor entry location(s). Once mitigation has been engaged, continuous monitoring is used to confirm that risk reduction objectives have been met. When aggressive remedies such as thermal remediation and oxidation are employed, continuous monitoring is used to assure all stakeholders that fugitive emissions are managed appropriately and to inform site managers when system adjustments are required.

Any project manager considering using in-situ thermal heating would be well advised to use continuous real-time monitoring of the rapidly changing emission scenario.  We have been able to anticipate and correct problems before the concentration levels became acute, which has saved time, money and energy.” – EPA Project Manager

It is clear that many of the difficulties associated with characterizing and managing vapor intrusion can be eliminated with continuous monitoring and response.  These systems should therefore be considered by industry practitioners as a cost-effective and viable method for quickly resolving vapor intrusion challenges.

Quick Service Industry Remediation

As an entrepreneur, franchisor, or small business owner, understanding the potential impacts of the environment may have an influence the success of your business. Poor air quality, waste, and pollution are all possible contributors that may affect  your business, but there are measures in place to minimize them. Many think of “going green” as recycling, switching to “paper free,” or ride sharing on their way to work. All these efforts are good for our environment, but there are other environmental impacts like contaminants in groundwater and soil that affect property and may require a remediation solution.

If you’re looking at properties to fix up and start a quick service restaurant as an example, taking a proactive approach in knowing the environmental history behind your purchase is always wise. There could be contaminated groundwater or soil under or surrounding the property that should be investigated to avoid potential  risk. For example, if you receive information that the property was a former dry cleaner operation or gas station, there is a high chance the property  will be  in need of remediation. Consider having the site tested by a professional to check  non-detect levels have been confirmed. Even if there are contaminants found on-site, you can still transform a former brownfield property to a high functioning quick service restaurant in a matter of months depending on the severity of the project. There are many government and regulatory requirements associated with the application of remedial technologies., Many environmental professionals involve the help of experts in the industry, like Land Science, a division of Regenesis.

Land Science has helped to remediate  hundreds  of these former brownfield sites across North America and has proven performance results with its vapor intrusion barrier system technologies like Geo-Seal, Retro-Coat and Vapor Ventr. Within the restaurant and food service industries specifically, Land Science has a reputation for providing successful and cost-effective outcomes. Therefore, it’s absolutely possible to achieve a safe environment in your new quick service restaurant property.

Response Action Outcome Issued by LSRP for New Jersey Child Care Center Following Successful Installation of Geo-Seal®

Project Highlights

lsrp vapor intrusion solutions

  • New Jersey Department of Health Issued Safe Building Interior Certification for Child Care Center.
  • Over 45,000 sq feet of Geo-Seal installed, ensuring a high level of vapor protection and meeting strict regulatory standards.
  • The vapor barrier met the requirements of the New Jersey Vapor Intrusion Technical Guidance and allowed construction to remain on schedule.
  • Indoor air sampling was conducted in conjunction with the close out of construction activities verifying the vapor barrier was performing as specified. The developer was able to open the child care center on time, generating revenue from the leasehold tenants.

Project Summary

The former building site was used for numerous commercial and industrial operations. Lisko Environmental was contracted by the client to remediate the site in order to make way for a new mixed-use building. During this site’s redevelopment, the building site was razed in order for a new building to be constructed in the same footprint. This new building is a mixed use development for two tenant spaces: trampoline park and child care facility. During the initial phases of redevelopment, an off-site source of cVOC’s was identified and suspected to be migrating towards the site. After further inspection, the developers found that there were dissolved phase cVOC’s present beneath the site at levels well above the NJDEP’s groundwater vapor intrusion screening levels.

In order to prevent harmful vapor intrusion, the new building was designed and constructed with 45,000 square feet of Geo-Seal and a passive vapor mitigation system. This Vapor Mitigation System (VMS) was installed in conjunction with construction activities in order to meet construction milestones in a timely manner. The VMS is passive consisting of a vapor barrier and sub-slab vent piping extending above the roof line fitted with turbine caps. No other mechanical components such as motors or vacuum blowers were necessary at this time, however this system could become an active VMS if needed in the future.

Technology

Geo-Seal is a vapor intrusion barrier which is placed between the foundation of the building and the soil pad.
Geo-Seal is a three part system which combines two layers of chemically resistant high-density polyethylene (HDPE) with a spray applied core layer. This system prevents harmful vapors from permeating through the slab allowing developers to ensure a healthy indoor environment. Installing a Geo-Seal system offers developers a lower total cost
to remediate and allows projects to move forward in a timely manner.

Results

The Geo-Seal vapor barrier was installed and smoke tested by Edgeboro, International Inc., a licensed Geo-Seal installer. With this barrier in place, the Licensed Site Remediation Professional (LSRP) issued a Response Action Outcome (RAO) letter for the Site and the developer was issued a Safe Building Interior Certification which meets the requirements of the New Jersey Department of Health and the Department of Children and Families Services allowing the child care facility to obtain applicable licenses and the developers to generate revenue from the tenants with out delays caused by environmental problems.

What is Vapor Mitigation?

Vapor mitigation is a segment of the environmental industry that is maturing rapidly. There are many new technologies emerging to prevent vapor intrusion which safely and effectively address a variety of structures. Vapor mitigation methods are classified as either passive or active.

Passive vapor mitigation involves barriers installed in existing buildings or pre-construction to prevent the entry of chemical vapors. Passive vapor barriers are installed in a variety of structures including homes, businesses, or other industrial buildings and are generally a cost-effective approach, making passive vapor barriers the most common and appealing method for vapor mitigation. One approach available for existing structures is to seal or fill the cracks in a building’s floor slab or around pipes and utility lines in walls. Retro-Coat™ is an example of a vapor barrier coating system that protects existing structures and can be customizable to fit the unique needs of the structure. Another method of passive mitigation is installing a venting layer in a basement which pushes harmful vapors toward the sides of the building and then outdoors. A third vapor barrier option involves installing a barrier made up of strong plastic-like sheets placed beneath a building’s foundation or in crawl spaces. At Land Science, Geo-Seal® is a safe and proven vapor barrier system comprised of three intensive layers designed and installed in newly constructed buildings. Scientifically tested to provide the highest level of protection from vapor intrusion, Geo-Seal is the trusted source for many environmental professionals and developers across the US and Canada.

Active mitigation is the practice of changing the pressure between the sub-slab and the inside of the building to keep chemical vapors out. This method is considered to be highly effective but is usually more expensive than a passive system due to the high cost of maintenance. A sub-slab depressurization (SSD) system involves the use of a blower or electric fan. A suction pit is installed in the sub-slab allowing for contaminated groundwater vapors to rise to the surface and into the structure. The electric fan or blower draws out the chemical vapors and releases them outside the building’s structure. This system is highly effective and is used for radon and VOC control. Another active mitigation system available involves building pressurization which adjusts a building’s heating, air-conditioning, and ventilation system indoors relative to the pressure in the sub-slab. When positive pressure is introduced inside the building, it prevents chemical vapor from entering the building. This method tends to produce a high energy cost and is considered to be less-effective compared to SSD.

Additionally, there are solutions developed using both passive and active methods. For example, a passive system can be designed to become active if needed and is offered as one of the options available through Land Science. Vapor Vent™ goes above and beyond by providing cost savings, speedy installation, and other performance benefits.
