Client Spotlight: Kenneth S. Tramm, PhD, PG, CHMM, Founder of Modern Geosciences

Ken TrammAn accomplished environmental professional, an author with a passion for textbook writing, a talented guitar playing musician, an entrepreneur, and a self-proclaimed difference-maker for the environment – all of these facets describe Kenneth S. Tramm, PhD, PG, CHMM.   Dr. Tramm is the founder and General Manager of Modern Geosciences, a leading provider of environmental solutions, and a trusted Land Science client.  When Kenneth founded Modern Geosciences in 2011, his goal was to build an environmental firm with a talented staff, focused on delivering innovative environmental solutions for its clients. Suffice it to say, Kenneth and his firm, based in Colleyville, Texas, a suburb of Ft. Worth, is indeed delivering on his objective of providing cost-effective solutions to environmental challenges for clients spanning a number of industry sectors.

Dr. Tramm’s Background and Experience with Land Science

Kenneth’s interest in impacting environmental remediation began in high school, where he developed an interest in earth sciences. Shares Kenneth, “When I learned I could apply engineering and geologic principals to earth sciences, it was a natural.  Then at Texas A&M University, I was lucky enough to find a new degree program that mixed engineering, geology, and physical sciences into a combined degree.  This gave me a good start to grow on.” After completing his Bachelors of Science in Bioenvironmental Sciences, Kenneth went on to earn his Masters and Doctorate of Science degrees in Environmental Science and Engineering from the University of Texas at Arlington. Prior to launching Modern Geosciences, Kenneth worked as an Environmental Practice Leader, managing a variety of high-profile projects across the United States.  When asked what he enjoys most about working with Land Science, Kenneth points to professional, collaborative team-work. “The Land Science technical staff are always helpful to bounce ideas off of”, says Kenneth. “We use several Land Science products in conjunction with traditional source removal and plume management.  We do a great deal of Vapor Intrusion Control System (VICS) design, installation oversight and confirmatory testing.  While we have used other products, Geo-Seal® has been a great off-the-shelf tool for us because it easily allows us to update our designs to better reflect permeation rates or specialty foundations our clients need.”  Underscoring the success of Geo-Seal®, Kenneth points out that in some years his firm has specified over a million square feet, and that the product has great acceptance from both regulators and equity partners.

Beyond the Environmental Industry

While managing Modern Geosciences no doubt keeps him busy, Kenneth manages to find time for one of his favorite hobbies- playing the guitar, a passion that eventually blossomed into playing with a band while at Texas A&M, and even led to radio airtime and a phone call from legendary record label Epic Records. Continues Kenneth, “We had the chance to play some cool gigs and made it on the radio, but as they say… the difference between a large pizza and a musician is that a large pizza can feed a family of five!” He also stays busy donating his time to several charities and helping shape college coursework/professional mentoring at Texas A&M and the University of Texas at Arlington. “There is no better feeling than selflessly helping another person”, shares Kenneth.  “I think the old adage from Winston Churchill of ‘we make a living by what we get, but we make a life by what we give’ says it best.” Married and with three children, he has also found time to author a textbook, Environmental Due Diligence: A Professional Handbook. Adds Kenneth, “It has been so cool to see it added to a lot of college curriculums.  It’s a collection of all the things I wished I had access to when I was just starting out and learning.”  True to his form of staying current with his work, Kenneth hopes to have the next edition out in 2018.

It needs to be 100%

Kenneth’s day-to-day responsibilities vary widely, and this variety is just one aspect of what he enjoys in his work. Shares Kenneth, “Simply put, I assist clients in problem solving. This could be designing an air compliance program one day, designing an investigation program for a refinery that was mothballed in the 1940s the next, or on another day, performing a building stress test to see if we can tackle vapor intrusion.  In between the large and interesting projects are plenty of basic due diligence, remediation, and regulatory projects too.  Each presents its own challenges and requires that you never underestimate what you are doing.  I firmly believe if you are going to do anything, it needs to be 100%.” To stay current with the constant flow of information and best practices in environmental engineering, Kenneth and his staff participate in several in-house and professional training events throughout the year. He also serves as an adjunct faculty member at the University of Texas at Arlington’s Civil Engineering department, which requires him to stay updated on the various dynamics of his field.

Cleaning up Brownfields

When asked what he enjoys most about his work, Kenneth is quick to point out that making a difference by creating solutions that ensure safe reuse of brownfield properties is extremely gratifying. “I like to think we make a difference,” he says. “While sometimes it may seem like a small step, everything we do to assist another job being created, help a part of the earth be a little less polluted, or help a client manage environmental risk is rewarding.  It is always fun to drive by old sites that have now been cleaned up, closed, and put back into use.”  Although Modern Geosciences has enjoyed success, Kenneth still sees room for improvement, and true to his nature, is always looking to take his firm to the next level.  Shares Kenneth, “I really want to focus on mentoring great people and doing great work.  We need to keep our eyes on delivering cost-effective solutions and growing our client base through direct experience and testimonials.  So far it seems to be working.” As for the future of the bioremediation industry as a whole, Kenneth sees innovation as a catalyst for even more effective treatment solutions. He concludes, “While we have some great basic tools for enhancing bioremediation, there are always new approaches and site-specific scenarios which require us to get creative.  I am not sure there are trends to follow on this, but I do see more and more firms considering options today that were fringe ideas just a few years ago.”

Land Science is proud to have Dr. Kenneth Tramm, Principal and General Manager of Modern Geosciences, as a preferred client and partner in environmental remediation, and appreciates his leadership and comprehensive approach in providing successful remediation outcomes for Land Science and its clients.

Multi-Residential Project Moves Forward Using Geo-Seal as an Effective Barrier to Protect Against Methane Concerns

Project Highlights

  • 186,000 square foot Geo-Seal Barrier installed to meet regulatory goals
  • Site development kept on-time and on-budget
  • 60-mil barrier system chosen to offer highest level of protection against methane exposure

Project Summary

During initial environmental due diligence, this property was noted to have elevated methane in the subsurface (in excess of 15% by volume). While this was a perfect location for a multi-unit residential development as it was next to major traffic corridors and near many Fortune 500 employers, the environmental concerns paused redevelopment planning.

Modern Geosciences (Modern) was asked to develop a remedial strategy that could incorporate a methane mitigation system within the building design. Drawing on over three decades of methane mitigation experience, Modern’s lead design engineer developed a cost-effective approach that satisfied all the parties plugged into the development. This included a customized passive collection layout and use of Geo-Seal to mitigate potential vapor concerns.

NFA Letter Received from the Alabama Department of Environmental Management after Geo-Seal Application

Project Highlights

  • Geo-Seal application helps obtain a No Further Action (NFA) letter from the Alabama Department of Environmental Management (ADEM)
  • Vapor intrusion barrier successfully reduces harmful contaminants left behind by former chemical plant operations
  • Geo-Seal applied to over 3,455 square feet

Project Summary

A fuel production facility in Alabama inherited environmental subsurface contamination when the site was acquired. The site was a former chemical plant operating since the 1960’s. The chemical plant functioned as a large quantity generator (LQG) of hazardous waste, manufacturing hydrocarbon, gum rosin, and tall oil-based resins for over 30 years. Site investigations revealed several contaminants from industrial sources, including chlorinated volatile organic compounds (cVOCs) and polycyclic aromatic hydrocarbons (PAHs) such as naphthalene. Dicyclopentadiene (DCPD) levels posed a particularly significant vapor intrusion threat, with sub-slab vapor samples reaching as high as 48,000 micrograms per cubic meter.

The environmental consultant was hired by the site owner to aid in navigating the ADEM’s voluntary cleanup program. The concentration of DCPD at the site indicated an elevated concern for potential contaminant vapor intrusion at the fuel production facility. Three of the existing buildings―a maintenance shop, laboratory, and control room―were at the highest risk for vapor intrusion based on the sub-slab vapor data. Based on the analytical data collected at the site, ADEM required that engineering controls, including vapor mitigation measures, be implemented in order to receive the coveted NFA letter. As a result, the environmental consultant specified a Land Science vapor intrusion barrier and installed it in the maintenance shop and control room in a retro-fitting capacity.

Nick Mjolsness: Specializing in Helping You Mitigate Vapor Intrusion Risk

Nick MjolsnessAsk Nick Mjolsness, Central Region Manager at Land Science, what he enjoys most about his work and you’ll likely get a response that may leave you a bit envious. By combining travel to many states in the Midwestern US with a skill set that involves treating a wide range of contaminants, Nick is able to combine a hands-on approach to vapor intrusion mitigation while discovering the beauty and diversity of the central US. It’s this combination of travel and making a positive impact on our environment that makes him appreciate his profession. “It’s extremely rewarding to see an environmental project, such as vapor intrusion mitigation, come to fruition from inception to application,” shares Nick. “And I really enjoy traveling. You get a real appreciation for the size of the U.S. when you are visiting multiple states each month.”

Love for Travel and the Environment Leads Mjolsness to Land Science

Whether it’s discovering a new city or simply moving from point A to point B, Nick is always on the go, moving forward, and it’s one reason he chose to pursue a career in vapor intrusion mitigation. Continues Nick, “vapor intrusion mitigation is a dynamic field that is constantly evolving, and Land Science has developed a reputation for leading the way with regards to both science-based solutions and support services.” Nick started with Land Science just over two years ago as the South Central District Manager, and worked out of the company’s Dallas office. In October of this year he relocated back to the Chicago area, where he graduated from DePaul University. “I’m excited about returning to a part of the country where I grew up. It is a treat to be back in Chicago, however I’ll admit I sometimes miss the warmer weather of Dallas!”

Collaborating with Environmental Professionals is Especially Rewarding

When asked what’s especially rewarding about his work, Nick points to the gratification that stems from being involved in so many various stages of a project, usually from start to finish. He also enjoys the collaboration of working with various teams at both Land Science and REGENESIS. Nick continues, “I like being involved throughout an entire project. For instance, we did a project recently that was about 18 months in duration, from the time that I became involved. I was able to see the project evolve from the planning and spec phases, to bid phase, and finally to the installation phase. Along the way, I was able to take photographs of the site that we will potentially use in a case study next year. This entire process can be a very gratifying experience because you are able to see your projects materialize from the earliest stage and then be present when Geo-Seal is being applied as the solution.” Another aspect of his work he appreciates is when a project he’s worked on is selected for a case study. “Creating and sharing a case study allows the project to live on as a potential reference for other clients. Sharing what has been successful on a project can assist other clients with similar project challenges.”

Land Science Stands Apart with a Focus on Vapor Intrusion Mitigation Solutions

In the years since joining Land Science, Nick has noticed a shift in the market. One of these is the increased trend toward specialization. Nick continues, “Something unique that Land Science offers is an exclusive focus on vapor intrusion. This specialization helps us see trends in every aspect of VIM.” Nick points out that another trend includes a much more conservative approach to handling vapor intrusion. “Lenders, insurance agencies, developers, engineers, you name it- they all want to be sure they are doing as much as they can to effectively mitigate the VI threat. This is a major reason why they come to Land Science. Land Science has developed a reputation for being at the forefront of vapor intrusion mitigation and completing projects to the highest standards.”

With so much change occurring within the industry, and specifically in vapor intrusion mitigation, Nick realizes the importance of staying current on the latest trends, regulations, and products. This involves attending and speaking at technical conferences around the country. He recently gave a presentation on vapor intrusion mitigation at the West Virginia Brownfields Conference in Charleston, S.C. in September.

Mjolsness Enjoys Travel, Hiking and Museums

In his free time Nick enjoys traveling, hiking, and touring museums. Thus far he’s traveled to Dubai and Oman, as well as Sweden and Norway, where his ancestors originated. For museums, the Museum of Science and Industry in Chicago tops his list.

When asked what it means to work for Land Science, Nick quickly points to the caliber of talented co-workers and the opportunity to work with so many different teams. He concludes, “Working at REGENESIS and Land Science is a chance to work with some of the top people in our field. I also enjoy the highly collaborative approach that comes with working with customer service, sales, marketing, research and development, and the other departments.”

REGENESIS is pleased to have Nick Mjolsness, Great Lakes District Manager at Land Science, and values his experience and ability to manage so many different aspects of vapor intrusion mitigation.

MassDEP Finalizes “Vapor Intrusion Guidance: Site Assessment, Mitigation, and Closure”

massachusetts

The Massachusetts Department of Environmental Protection (MassDEP) finalized their Vapor Intrusion Guidance: Site Assessment, Mitigation, and Closure document on October 14, 2016.  As stated from the guidance, “This document provides guidance on investigating, assessing, understanding, and mitigating vapor intrusion at disposal sites regulated under Massachusetts General Law, chapter 21E and the Massachusetts Contingency Plan.”

The vapor intrusion guidance was in draft form since October 2014 and went through a lengthy public review process prior to it being finalized.  For the most part, there were no substantial changes from the public comment draft version of 2014 to the final guidance; however, there were numerous changes in terminology and clarifications on various items throughout each section.

Wondering how this might affect your site or your remediation plans? Land Science® can assist with providing some of the insight into the new guidance document. Contact Land Science, we have a team dedicated to vapor intrusion and mitigation solutions.

California DTSC Updates PCE Screening Levels

California has issued revised screening levels (SL) for vapor-phase tetrachloroethylene (PCE). On September 8, 2016, California’s Office of Environmental Health Hazard Assessment (OEHHA) adopted an updated inhalation {Cancer} unit risk (IUR) factor for tetrachloroethylene (PCE). Updating the IUR also created revised recommended residential and commercial/industrial ambient air and soil gas screening levels (SL) for PCE. The Department of Toxic Substances Control’s (DTSC’s) revised PCE SLs are slightly more conservative than previous and remain below the United States Environmental Protection Agency (USEPA) SL for PCE. The USEPA’s SL are higher due to the use of a less conservative IUR (2.6E-07) than DTSC’s (6.1E-06) to derive its current SL; however, the USEPA acknowledges that the general IUR should not be used in all cases for evaluations and that “A number of uncertainties underlie the cancer unit risk for PCE…” Learn more by downloading the US EPA’s Chemical Assessment Summary of PCE here.

Below is a table of the former and revised DTSC SL’s.

California DTSC updated PCE screening levels

On October 17, 2016, California’s DTSC Human and Ecological Risk Office (HERO) issued a response to inquiries associated with the PCE revised IUR and SL. Refer to this memorandum for further details associated with the updated IUR and SL’s. These SLs should be used in conjunction with the June 2016 Human Health Risk Assessment (HHRA) Note 3. DTSC indicates that a subsequent update to the HHRA Note 3 will be issued December 2016/January 2017, which will include the changes to the PCE toxicity criteria.

The exposure and risk factors for PCE and other chlorinated constituents, within the vapor phase, continue to be at the forefront of many regulatory agency mandated updates and often generate several topics of discussion. The overall trend continues to be conservative when evaluating the risk of these constituents. Ultimately, directing many site evaluations towards pre-emptive mitigation approaches, such as vapor intrusion are highly recommended to comply with increasing regulatory guidelines.
