Client Spotlight: Dan Matz, Environmental Engineer at Bunnell Lammons Engineering, Inc.
For Dan Matz, a career in environmental remediation provides the ideal combination of variety and pace to keep him both energized and challenged. As an Environmental Engineer at Bunnell Lammons Engineering, Inc., a leading environmental and geotechnical engineering firm and valued Land Science® client, Matz plays a key role in a broad range of the firm’s environmental services. “My primary responsibilities are Phase I and Phase II Environmental Site Assessments and Brownfield redevelopment projects,” he shares. “We commonly call these our ‘Due Diligence Services’ because they are designed to better inform clients about a property prior to the acquisition of it.” The diversity of his work, along with the demands of short due diligence periods can be challenging, but that’s just what keeps Matz moving at full speed. He shares, “Working in the field of environmental remediation is very gratifying.”
As someone with a love for the outdoors since childhood, Matz wasn’t surprised when that passion led him to focus his university studies in environmental engineering, where he earned his B.S. in Physics of the Environment at Furman University. He continues, “I developed my own major, and tailored it toward an engineering degree. My degree was a combination of physics, math, and environmental science.” He followed his undergraduate degree by earning a Master of Engineering in Environmental Engineering and Science from Clemson University. He then joined Bunnell Lammons Engineering, Inc., where he’s served since 2008, first as an Environmental Engineering Associate before being promoted to Environmental Engineer.
To stay current with industry trends and technology, he attends multiple conferences per year, and participates in webinar trainings and “lunch and learns” at the office. He adds, “I try to focus my continuing education on vapor migration, groundwater and vapor remedial techniques, and Per- and polyfluoroalkyl substances (PFAS/PFOAs) .” Suffice to say, he thoroughly enjoys what he’s doing, and takes pride in knowing he’s making a positive impact in the community. He shares, “I like the quick turnaround time on projects. When environmental concerns arise, it is exciting to determine the best solution for the client to move forward with the transaction, whether it is a Brownfields agreement with the state or some other avenue of environmental protection. It is rewarding to work on real world environmental problems and help my clients determine solutions to mitigate risk, keeping in mind their project schedule and budget.”
When it comes to working with Land Science®, Matz appreciates the timely response and level of expertise he receives. He shares, “Land Science® is responsive. You ask a question of a Project Manager and they answer it quickly and thoroughly. They provide support on VI design, install, etc., which makes my job as an engineer easier in support of my clients. They are industry leaders and have the solutions to the problems we face.” He currently has four projects with Land Science®– two Retro-Coat™ applications and two Geo-Seal® applications. “The support and assistance they have provided on each of these projects is remarkable, and we have a good working relationship with them,” he says. About specific Land Science® products and solutions, he says Geo-Seal®, Retro-Coat™, and Vapor-Vent are all used in various ways, depending on the site requirements.
When asked about the future goals of Bunnell Lammons Engineering, Inc., Matz says continued growth and providing superior service are always at the top. Currently, the firm has more than 125 employees between its various divisions: environmental engineering and consulting, geotechnical engineering, construction materials testing, transportation services, and solid waste services.
Residing in the Greenville/Spartanburg, South Carolina area, where he works out of the company’s Greenville office, Matz and his wife Laura, have two young children, Ryan, age 4, and Erin, six months. In his free time, Dan can be found out on the nearby roads, training for his next half marathon or triathlon. Additionally, Dan and his family enjoy rooting on their favorite football team, the Clemson Tigers.
When asked what he sees the future holds for environmental remediation, he says PFAs and PFOAs are garnering a great deal of attention. He continues, “There is a lot of talk about these emerging contaminants, but we will see where it goes. If more regulatory agencies start to develop action levels, it could become a BIG issue in years to come. The science is relatively new, and there are a great deal of discoveries to come in future.”
And what is it he likes most about his work? “Helping clients solve their environmental problems and allowing them to purchase and redevelop properties that otherwise might sit vacant and underutilized.”
When prompted to share how he would encourage others to join in his field of study, he again points out the quick cadence his work entails, and the satisfaction of helping clients. He concludes, “I tell people interested in the field the industry is a fun, fast paced work environment. It is exciting to work on a variety of projects and provide clients with solutions.”

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.
For 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.
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.
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.
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.
Employee Spotlight: Kim Bradley, Inside Sales Manager
As one who has followed REGENESIS’ growth for many years, joining the company’s Land Science® division as its new Inside Sales Manager was especially gratifying for Kim Bradley. “I have enjoyed watching REGENESIS grow over the last 20 years,” says Bradley. “Over that time, I have seen the company evolve into a leader in remedial technologies for both in-situ remediation and vapor intrusion mitigation.

Our industry has become heavily regulated, resulting in a variety of potential innovative solutions. It’s been my experience that as long as a regulator sees that you have a plan with a reasonable timeline in place, they will work with you.”
While earning her Bachelor of Science in Civil Engineering from Michigan State University, Bradley enjoyed the environmental course work and became interested in a career in environmental engineering as a way of returning the environment to its natural state so that land can be rejuvenated and utilized again. After graduation she immediately began her career in Southern California as a consultant, project manager, and client advocate in the environmental, process safety and construction arenas.
When asked what she feels the future holds for environmental remediation, she points to the increased attention and emphasis within the regulatory space. She continues, “The regulatory requirements will only become more stringent with time, and I foresee more regulation focused on long-term solutions and more incentives or tax credits made available in exchange for compliance.”
Residing in Laguna Niguel, Bradley is the mother of two children, and in her free time enjoys an array of water sports such as kayaking, white water rafting and boating. She also finds time for alpine skiing, hiking and camping, and is an avid college/professional football, baseball and hockey fan. In her spare time she donates and volunteers for the Alzheimer’s Foundation and to her local Business Development Guild. With regard to our planet and environment, she feels we all have a role to play in sustainability. “Everyone needs to embrace making our environment a healthier place to live, and I’m enjoying the fact that I can potentially make an impact.”

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.

Brownfield Developments
Brownfields are a big concern in the U.S. due to the environmental, economic, and political issues they represent. A Brownfield site is a property whose sale or reuse is prevented due to the presence of contaminants or pollutants. While these properties often pose liabilities for the communities they are a part of, they also represent business opportunities for environmental consulting firms and can be a springboard for community redevelopment and economic revitalization because of the EPA’s Brownfields Program.
The US EPA is behind many of the developments concerning Brownfield sites. This US EPA provides grants and technical assistance to communities to assess, safely clean up, and sustainably reuse contaminated properties. The grants make way for ensuring clean air, water, and land preservation and restoration.
A study done in 2015 proves the economic value of cleaning Brownfield properties outlining the benefits to communities and citing positive outcomes like residential property value increasing by up to 15% within 1.5 miles from the affected site. Every year the US EPA assesses its accomplishments among the nation’s communities. The most recent and comprehensive results as of May 1st, 2017 include: 26,722 properties assessed nationwide, 124,760 jobs leveraged from the results, $23.950 BN dollars leveraged, and 67,419 acres anticipated to be ready for use again. These numbers are promising in the developments at Brownfield sites. In Pennsylvania for example, the state received $1.8 million in funding to examine Brownfields. This enacted local organizations to take on many new projects while making significant progress in impacting contaminated sites.
While the benefits of the EPA Brownfields program are clear, challenges remain for property developers and environmental professionals who are tasked with cleaning up and remediating these sites before they are cleared by regulators for re-use. Perhaps most notably, vapor intrusion from soil and groundwater contaminants is often a problem that must be mitigated. As risk standards and other compliance issues associated with contaminant vapor intrusion continually evolve, engineered controls like those offered by Land Science provide a practical, cost-effective solution to eliminate risks.
Recent advances in contaminant vapor intrusion mitigation developed by Land Science have assisted developers, engineering firms, regulators, and land owners by providing technically sound solutions effectively mitigating these issues. These solutions include Geo-Seal Vapor Intrusion Barrier for new building construction, and Retro-Coat Vapor Intrusion Coating for existing structures.
Land Science is a vital part of Brownfield developments in the environmental industry. Land Science contracts with environmental consultants and developers to remediate contaminated Brownfield sites using effective technology and product solutions. There is a lot of value in cleaning up Brownfields that positively affects not only the environment but our economy and communities. Land Science takes pride in Brownfield development efforts nationwide. Most notably, in 2016 Land Science won the Phoenix Award for an impressive brownfield revitalization project. The project was a severely contaminated site that was remediated and redeveloped into the Cardinal Health Center in Michigan. Additionally, Land Science attends Brownfield conferences annually which focus on environmental rejuvenation to stimulate economic activity in contaminated areas.
