5 Reasons to Consider a Preemptive Vapor Barrier to Protect Your Property Investment

5 Reasons to Consider a Preemptive Vapor Barrier to Protect Your Property Investment

Historically, easily-punctured thin-mil plastic sheets or inflexible and difficult-to-seal High Density Polyethylene (HDPE) Barriers were the only option for vapor mitigation at large warehouses or sites where regulatory requirements were not a driving risk factor. These solutions offered either chemical resistance or constructability, but not both. Composed of an innovative, metalized-film, MonoShield sets the standard for preventing diffusion and permeation of chemical vapors. Its nitrile-based asphalt latex ensures a seal far more effective and easier to apply than tape-based or heat-welded systems. Download the ebook to learn more.

Denise Sullivan

Client Spotlight: Denise Sullivan, Principal and Owner of Urban Green Environmental, LLC

Ask Denise Sullivan, Principal and Owner of Urban Green Environmental, LLC, an environmental consulting and engineering firm and valued Land Science® client, about how she chose a career in environmental remediation and you’re likely to get the response, “Well, my career chose me.” That’s because Sullivan, upon graduation from Tufts University, where she earned her BS in Civil Engineering, found that most of the jobs readily available were in the environmental market, predominantly investigating and remediating properties for environmental impacts and contamination. She shares, “I needed a job, and at the time I never would have guessed that I would find my passion for my career in that first job. My first position was at a company, Ensol, Inc. in Billerica, Massachusetts. It was a small firm, much like Urban Green Environmental, which I started in 2007, and I have modeled much of our internal culture at Urban Green Environmental based on my early experiences at Ensol.” Becoming an entrepreneur and starting her own business targeting the environmental sciences had always been a dream for Sullivan as a way to own and grow her own company while also giving back to the environment. She says her success is based upon nurturing a strong entrepreneurial spirit and choosing a field that she is passionate about. She continues, “I have dedicated my career to the environmental field and have worked hard to carve out a niche where my firm can successfully balance environmental goals with economic development. My proudest accomplishment as a business owner is the team of committed individuals that comprise Urban Green. In 2007, despite the challenging economic climate, I felt the time was right to invest in myself, my adopted hometown of Baltimore, and establish a niche firm focused on environmental investigations of Brownfields and urban in-fill properties. When I started, I was a one-person company and operated out of my home. Today, Urban Green has six employees, an expanding office in Locust Point, and a clear mission and vision.”

When asked about working with Land Science®, Sullivan feels the range of products offer important solutions towards successful project completion for their clients. “We have several projects in Baltimore City that employ the use of Land Science® vapor barriers,” she says. “Specifically, Geo-Seal® and Retro-Coat™. It is rare to have a project in our Maryland Department of the Environment Voluntary Cleanup Program, particularly in an urban environment such as Baltimore City, where we do not spec a vapor barrier with proven resistance to volatile organic compounds, known as VOCs. Retro-Coat™ has been a critical product for many of our projects, and we have used it with great success on some of our current projects.” As one would expect, staying current in an ever-changing industry can have its challenges, so Sullivan regularly attends the National Brownfields conference as well as local Brownfield conferences to stay abreast of the latest trends and technology. When asked about the future goals of Urban Green Environmental, she emphasizes the company’s need to remain focused on providing current solutions for successful outcomes. She shares, “Our mission is to investigate properties for environmental liabilities and provide solutions to those liabilities for private and public organizations and institutions. We have a wide array of clients in the public, private and non-profit sectors and are excited about the future of the company.”

Recently married for the first time and residing in Baltimore, MD, Sullivan’s husband also plays a key role in Urban Green Environmental’s success. She continues, “I’m married to a wonderful Frenchman, Sylvain Masset, who is also an engineer with a focus in the air testing equipment industry (ATI). His expertise has been invaluable over the past few years as Urban Green has developed diagnostic testing protocols for our vapor mitigation systems.” Outside of work, they enjoy hiking on weekends, and she hopes to one day build a new home with her “talented husband.” She also finds time to serve as a member of the Advisory Board for The Baltimore Center for Sustainable Careers (BCSC), a project of Civic Works, Baltimore’s non-profit service corp. In addition, she volunteers as an instructor for the B’more Green Brownfields Training Program, a workforce development program. “Since 2004, I have provided classroom instruction for future environmental field technicians, and I’ve also hired two graduates from this training program.” When asked about the most challenging aspect of her work, Sullivan points to the need to work effectively with people, yet stresses this can also be rewarding as well. She continues, “For me, working with people in general is the most challenging and the most rewarding. I believe our best efforts come from a team, and I find myself awed and so very lucky at the team that has been attracted to Urban Green. They work so hard and are extremely dedicated.”

As the environmental remediation industry continues to evolve, Sullivan sees potential for continued growth and development, particularly in soil and demolition materials, as well as vapor intrusion and mitigation. She shares, “Other than the investigation and remediation of PFOAs, which it seems most in our industry are tracking closely, I think we’ll continue to see progress in densely developed urban areas and on brownfields, along with emerging trends for the re-use of soil and demolition materials (concrete, brick, etc.) and vapor intrusion/mitigation.” And what advice would she give to others who might be considering a career in environment remediation? She concludes, “That’s an interesting question and one that is difficult for me to answer. I would encourage folks who are curious about Brownfields or contaminated properties who want to make an impact on the future of our environment to get involved early on and nurture their curiosity by exploring the various career paths that are out there.”

Land Science® is proud to have Denise Sullivan, Principal and Owner of Urban Green Environmental, LLC as a valued client and partner in vapor intrusion mitigation, and appreciates her diverse experience and knowledge base in providing successful remediation outcomes for Land Science® and its clients.

Prem Neupane

Client Spotlight: Prem Neupane, Program Manager with Apex Companies, LLC

Prem NeupaneAs an experienced Program Manager with Apex Companies, LLC, a leading environmental services firm and valued Land Science® client, Prem Neupane has an ongoing appreciation for seeing firsthand how his efforts and those of Apex can make a difference in site cleanup. “When I compare the before and after activities at the remediation site,” he says, “Especially those in the State Voluntary Cleanup Program, Brownfield program and sites located in urban areas, our project work continues to provide me with great satisfaction.” With 18 years of experience at Apex, first as an Environmental Scientist, then as a Project Manager and now as a Program Manager, Neupane has been involved in a diverse range of remediation projects. In his current role, he manages several clients, participates in business development, and manages all aspects of his project work-  from initiation to close-out.  He shares, “I like interacting with clients, our trusted vendors and suppliers/lab, and fellow Apexians, and ultimately finding the optimum solutions for environmental remediation problems.” Prior to joining Apex, Neupane performed a year-long internship with the USGS in Dover, DE working on the Air Force Base projects. To prepare for a career in environmental science he earned a BS in Environmental Science from Troy University, followed by a MS in Science and Water Resources at Miami University in Ohio. He continues, “I became interested in the environmental field during high school.  After completing my undergrad studies at Troy University, I went straight to graduate school to further enhance my knowledge on environmental issues.  While working on my Master of Science at Miami University, I was able to take a few advance level courses in contamination, and shifted my focus toward environmental characterization and remediation. Aside from seeing projects through to fruition, it’s the interdisciplinary nature of this field that interests me the most.”

With nearly 20 years of experience in the environmental industry, Neupane takes great pride in his work, while continuing to focus on the company’s long-term goals, which include the practice of utilizing sustainable remediation technologies. He continues, “At Apex, our plans are to strategically grow the company by harnessing the power of innovation, especially in the use of green remediation. We continually invest in leading-edge, sustainable remediation technologies and in remediation experts who can develop and deploy them. Beyond our use of evaporative desorption technology (EDT),  ex-situ on-site bioremediation, cryogenic vapor treatment technology (CVTT), and remote station soil vapor extraction (SVE) – which are just a few ways we help our clients move to more effective results –we plan to adopt and deliver more efficient, practical, and sensible remedial strategies that continue to benefit our clients and communities.” When it comes to working with Land Science®, he continues to be impressed with their client service, responsiveness, and their ability to provide assistance with product recommendations that fit a variety of challenges and situations. He points out that on a recent project, and on short notice, Land Science® met the Apex team at the job site to discuss solutions for an existing issue. As for which Land Science® products Apex uses, two come to mind. He shares, “Geo-Seal® and Retro-Coat™ vapor intrusion coating are those we have used the most. However, we are open to the new products Land Science® has rolled out recently. Geo-Seal® is a composite vapor intrusion barrier system that consists of chemical resistance high density polyethylene (HDPE) and spray applied asphalt latex.  It is ideal for installation on new construction. Retro-Coat™ consists of chemically resistant material that is applied to existing structures to prevent potential vapor intrusion risks.  I like them both because they are relatively easy to apply, are compatible and effective with VOCs from petroleum as well as chlorinated solvents sources, and they are very popular and well liked by regulators.”

When asked about the future of environmental remediation, including trends on the horizon, Neupane points to advancements in technology that enable more accurate targeting of contamination in subsurface and faster analysis. He also expects to see more cost-effective solutions, greener cleanups and green remediation to minimize the environmental “footprint” of remediation activities, emerging contaminants, and vapor intrusion solutions. He notes that the EPA describes green remediation as “The practice of considering all environmental effects of remedy implementation and incorporating options to maximize net environmental benefit of cleanup actions.”  He continues, “Some local and state regulatory agencies, such as the Department of Energy & Environment (DOEE) in Washington, DC, are encouraging responsible parties to consider and report green remediation strategies for remediation sites.  Green remediation allows us to reduce the environmental footprint of a cleanup project.” To stay abreast of emerging technologies and trends, Neupane regularly attends seminars and training modules, and participates in webinars offered by remediation industries and coalitions, such as those offered by the Interstate Technology & Regulatory Council (ITRC). He shares a recent example of a training seminar he attended in May of last year, “I attended Vapor Intrusion (VI) & Soil Gas Training provided by Dr. Blayne Hartman of Hartman Environmental Geoscience, at Argonne National Laboratory in Chicago.  The training was very informational and covered the latest in regulatory, assessment, sampling, analysis and mitigation, as well as legal considerations.” When prompted about the most challenging aspect of his work, he feels accounting for project uncertainties and including contingencies to complete the remediation work on budget and on time can be difficult. “Weather can also be a challenge sometimes,” he says, “Especially with large scale water related projects during winter months.”

Currently residing in Chicago, with his wife and daughter, Neupane works out of Apex’s downtown Chicago office, and frequently travels to the company’s Washington, D.C. region for project work and meetings. In his free time, he enjoys hiking, biking, and visiting new places with his family. He shares, “Having grown up in Nepal, I was always drawn to the beauty of the Himalayas.  I visit Nepal and try to hit the hiking trails there whenever possible.  I was in Nepal just this past October with the family and did some hiking near Mt. Annapurna (10th tallest mountain). Whenever I travel to a new place I seek out nearby hiking/biking trails.” And how would he encourage others to join his field of study? He concludes by emphasizing the potential long-term contributions that his profession makes possible.  “Remind those who may be interested that they can make a positive impact on human health and the environment. Look at the bigger picture and think of your contribution to future generations.”

Land Science® is proud to have Prem Neupane, Project Manager for Apex Companies, as a valued client and partner in environmental remediation, and appreciates his expert knowledge and experience in providing successful remediation outcomes for Land Science® and its clients.

Managing Principal for ATON Langan Discusses Environmental Strategies for Protecting Assets

For Ron Carroll, owner and Managing Principal of ATON LLC, choosing a career in environmental remediation was both a personal and professional choice. That’s because when he was younger, Mr. Carroll lived near and had friends who were impacted by the Times Beach dioxin cleanup project in the St. Louis area. As a result of toxic chemicals being mixed with oil and applied to roads for dust control, a massive cleanup was initiated in St. Louis County. Consequently, the EPA ended up buying many of the homes within the town to facilitate an effective cleanup in the area. Understandably, this environmental hazard and subsequent remediation project left an indelible impression on Mr. Carroll. Learn more in our client spotlight.

5 Reasons to Consider a Preemptive Vapor Barrier to Protect Your Property Investment

5 Reasons to Consider a Preemptive Vapor Barrier to Protect Your Property Investment
Historically, easily-punctured thin-mil plastic sheets or inflexible and difficult-to-seal High Density Polyethylene (HDPE) Barriers were the only option for vapor mitigation at large warehouses or sites where regulatory requirements were not a driving risk factor. These solutions offered either chemical resistance or constructability, but not both. Composed of an innovative, metalized-film, MonoShield sets the standard for preventing diffusion and permeation of chemical vapors. Its nitrile-based asphalt latex ensures a seal far more effective and easier to apply than tape-based or heat-welded systems. Download the ebook to learn more.

Client Spotlight: Ron Carroll, Owner and Managing Principal of ATON LLC

Ron CarrollFor Ron Carroll, owner and Managing Principal of ATON LLC, an environmental consulting and engineering firm and valued Land Science® client, choosing a career in environmental remediation was both a personal and professional choice. That’s because when he was younger, Mr. Carroll lived near and had friends who were impacted by the Times Beach dioxin cleanup project in the St. Louis area. As a result of toxic chemicals being mixed with oil and applied to roads for dust control, a massive cleanup was initiated in a small town in St. Louis County. Consequently, the EPA ended up buying many of the homes within the town to facilitate an effective cleanup in the area. Understandably, this environmental hazard and subsequent remediation project left an indelible impression on Mr. Carroll, and he eventually pursued and earned a B.S. in Environmental and Hazardous Materials Management, and a B.A. in Biology, from the University of Findlay. In addition to his university degrees, he also became a Certified Hazardous Materials Manager and Certified Industrial Hygienist. His university studies and professional work experience that followed would eventually culminate in forming ATON, where he oversees the firm’s business activities. He shares, “I’m responsible for managing our environmental, health and safety consulting work, and all administrative operations.  I also conduct and oversee site inspections, multi-media sampling, coordination and negotiation with regulatory agencies, facility decommissioning, demolition, and regulatory reporting.” Prior to forming ATON eight years ago, Mr. Carroll held management positions with a national due diligence and real estate assessment company performing environmental, building sciences, and valuation services; and a national environmental engineering consulting firm that provided site investigation, industrial hygiene, remediation, and regulatory compliance services.

When asked what he likes most about his work, Mr. Carroll points to the benefits that result from consistent teamwork. He continues, “I enjoy interacting on a daily basis with our employees and clients to find sound technical solutions to challenging problems. I also take satisfaction as a mentor to technical staff and as a trusted advisor to our clients in the commercial and industrial sectors.” And the most challenging aspect of his work? “Keeping track of ever-changing regulations and how those regulations affect our business and our clients’ business. While it can be challenging, we feel we’re well-equipped. We’re looking to continue our growth organically by adding key technical staff and expanding geographically. We also see the redevelopment of brownfields as a significant growth area for the company.” When it comes to working with Land Science, Mr. Carroll appreciates the combination of innovative solutions and service ATON receives on a consistent basis. He continues, “Land Science continues to provide a quality product with seamless technical expertise, and this helps in the design and implementation phases of our remedial work. We were recently involved in the relocation and development of a large scale, commercial laundry operation in the St. Louis region that involved the construction of a building over a former chemical plant that is highly regulated by the EPA. The success of the redevelopment using Land Science products led to the continued development of industrial warehouse space near the former plant. In essence, the Land Science solutions form a complete package that typically exceeds our design specifications.”

Residing in St. Louis, with his wife and two children, Mr. Carroll likes to spend his free time with his family, enjoying the outdoors, traveling, and attending various sporting events. “We have a great baseball team, the St. Louis Cardinals,” he says, “and the Stanley Cup hockey champs, the St. Louis Blues.” He also finds time to give back to his community as a volunteer for Habitat for Humanity. To stay abreast of emerging trends and new technologies, ATON offers all its employees continuing education and technical training for environmental, health & safety (EHS) consulting and remediation work. When asked how he he’s seen the industry change, his focus turns to the advancements made possible through innovation. He continues, “We’ve seen technical innovation working its way into what historically has been a labor-intensive industry. In the past we’ve relied on field sample collection and off-site analysis for environmental contaminants. More recently, we’re able to use smaller and lighter field instruments to detect and analyze contaminant concentrations without having to send samples to a laboratory. In addition, innovations in data collection and management have allowed us to compile data and issue reports much quicker, which in turn allows our clients to make more informed and faster decisions on tight timeframes.” Asked what he sees the future holds for environmental remediation, he feels the consulting side of the business will continue to grow. He shares, “We see the traditional EHS consulting field continuing with strong growth. The environmental remediation industry also continues to grow through local, state, and national brownfield development initiatives.” And how would he encourage others to join his field of study? He concludes, “Education and training in STEM are keys to our success and growth. I would encourage others interested in science and the environmental field to become STEM practitioners and supporters as a way to enter this industry.”

Land Science is proud to have Ron Carroll, Managing Principal of ATON, as a valued client and partner in environmental remediation, and appreciates his vast experience and knowledge base in providing successful remediation outcomes for Land Science and its clients.

vapor intrusion mitigation

Four Facts You Should Know About Vapor Intrusion

Vapor intrusion is the migration of vapor-phase contaminant chemicals from a subsurface source in an overlaying building or structure. The objective of many vapor intrusion investigation professionals is to be able to detect possible pathways for contaminant vapors and their location within the building or structure. Understanding the potential pathways helps to identify risks. A solid understanding of potential pathways informs the client selling the building to potential tenants, who need to be able to live and function within the building without exposure to health risks. Here are four key things to know about vapor intrusion.

It’s A Process

Number one, vapor intrusion investigation and mitigation is a process. Vapor intrusion science requires in-depth investigation. It is not a field which requires only one test to say whether a building does or does not have vapor intrusion. In-depth investigation includes options based on the site and its environment. The in-depth investigation must determine what type of gases are emitting through the cracks, where the origin and the major intrusion pathway are  located. Additionally, the consultant’s next step is contacting the local government environmental representative to confirm the state’s regulatory guidelines and to receive approvals for developing the site. Even after all the preparation work and investigations, the environmental consultant will have to develop a design to cover the exact needs of the site. There is no quick way to handle vapor intrusion. Each site must be evaluated thoroughly to move onto the next step to mitigate the effects of the vapor intrusion.

Recognize Outside Factors

Though thorough investigation is necessary to get an accurate reading of the site, the results may not be complete. At times investigations or screenings of a site will pick up additional vapors from the testing area or concentrated in one single area to indicate contaminants present. These readings could be caused by a number of factors, even common household appliances on site. For example, if an industrial adhesive product like E6000 glue is located anywhere in the screening area, there will be a significant increase in TCE indicated in the testing, which would easily skew the readings. So, Before any screening can be performed on site, investigators should go through the site with a close eye looking for indoor VOC sources, like paints, cleaning supplies, or insecticides. For more information, visit the EPA’s website regarding the specific materials to look for in a site, along with other information to address VOC concerns is a great resource: https://www.epa.gov/indoor-air-quality-iaq/volatile-organic-compounds-impact-indoor-air-quality.

In a webinar with Land Science, and the Compound Specific Isotope Analysis (CSIA) Lab Director of Microbial Insights provides some tools to help distinguish whether the source of vapor-contaminated indoor air originates from the buildings subsurface or an indoor source.

There are other uncontrolled factors that could contribute to excessive readings, including spatial and temporal variability. Some examples of spatial variability factors to consider are soil types like gravel or sand, bedrock fractures, oxygen distribution in the soil, subsurface building structures and even surface features like pavement or water features. Each of these examples either provide a clear path for VOCs to reach the site or the groundwater or affect how quickly VOCs could reach the site. Examples of temporal variability include: wind speed and direction, barometric pressure, temperature inside or outside, precipitation, and ambient contaminants. These variables can affect how the screenings read the concentrations of VOCs at the site.

Solutions Are Site Dependent

Vapor mitigation professionals are also tasked with developing a solution based on the site’s conditions along with the state/federal regulations. Each site is different, so vapor mitigation often cannot be based on a plan used at a former site with similar conditions. The investigations unveil all the aspects of a site that determine what the remediation plan will be, including: soil types, weather patterns, gas distributions, subsurface conditions, as well as site goals and budget. Each one of these factors can impact the design of a vapor mitigation system, and each factor can yield different results.

Land Science is comprised of a team of vapor intrusion mitigation professionals who have the technical expertise and industry experience to make the most effective recommendations for our clients. Couple that with a range of innovative technologies that address a variety of site types, and the result is industry-leading vapor intrusion solutions that help public safety.

It’s a Growing and an Evolving Science

The final key idea behind vapor intrusion science that everyone should know, it is a growing and an evolving science. The reason vapor intrusion science came into existence was because of the avid use of VOCs—volatile organic compounds–as root zone fumigants and other applications in the 1950s. Surveys of landfill gas and radon exposure in the 1960s lead to the discovery of vapor intrusion in the late 1970s and was found to affect indoor air quality at heavily contaminated sites, which brought the full scope of regulatory attention.

However, at this point, scientists and regulators dismissed the concerns to homeowners due to the processes of dilution and attenuation as well as the ambiguous exposure standards and the fact that most vapor intrusion was found at major former industrial sites. Consequently, scientists began finding vapor intrusion inside residential homes and decided to facilitate public education by going door-to-door and providing information on the issue of vapor intrusion.

The increase in public awareness resulted in a rise of attention and studies regarding vapor intrusion through the 1990s to the 2000s, pushing states to start developing vapor intrusion protocols and ultimately causing the EPA to publish “Guidance for Evaluating the Vapor Intrusion to Indoor Air Pathway from Groundwater & Soils.” Today 42 states have developed their own regulation system for vapor intrusion and the other 8 follow the EPA’s regulation system or deal with vapor intrusion on a case-by-case basis. The history of vapor intrusion has expanded over decades; from the introduction of VOCs in the 50s to the development of a national regulation standards in the 2000s, vapor intrusion science has gone through many changes and continues to develop. Those who work in the field of vapor intrusion must expect continuous changes, whether it be through regulation,  techniques, or emerging science on its effects.

This evolution has caused remediation companies notice and respond to the demand and serves to further develop the technology. For instance, Land Science, a division of REGENESIS® and a global leader of advanced vapor intrusion mitigation technologies, recently introduced TerraShield – a cutting-edge remediation technology which provides superior chemical resistance over any vapor barrier on the market today. Land Science also offers a full-suite of vapor intrusion barrier systems including Nitra-Seal, a proven vapor barrier system now improved with nitrile; and MonoShield, a chemically resistant and easy-to-apply barrier specifically designed as a preemptive solution for vapor intrusion at brownfield redevelopment sites and Retro-Coat, a chemically resistant vapor barrier coating system to properly protect existing structures from the threat of contaminant vapor intrusion . With solutions like TerraShield, Nitra-Seal, MonoShield and Retro-Coat being made available to vapor intrusion mitigation industry, this field is now poised to address the needs created by an increasingly demanding regulatory landscape.
