Founder and CTO, Groundswell Technologies, Inc., specializing in automated Cloud-based monitoring and modeling of environmental sensor and analytical instrumentation networks
Dr. Mark Kram is the Founder and CTO for Groundswell Technologies, Inc., a group specializing in automated Cloud based monitoring and modeling of environmental sensor and analytical instrumentation networks.
Dr. Kram earned his PhD in Environmental Science and Management from the University of California at Santa Barbara, an MS degree in Geology from San Diego State University, and his BS degree in Chemistry from the University of California at Santa Barbara.
With over 30 years of experience developing innovative environmental assessment techniques, he has authored articles, national standards and book chapters on the subject, and has taught graduate level courses on related topics.
Dr. Kram is an internationally recognized expert in site characterization and remediation, and has been instrumental in the areas of sensor development and implementation, innovative GIS applications, DNAPL site characterization, chemical field screening, well design, direct push well acceptance, mass flux/discharge based remediation performance, and groundwater basin yield and storage change assessment.
Credited with gaining international approval for use of direct push wells for long term groundwater monitoring, Dr. Kram has patented inventions for automated sensor based visualization and multivariate analyses, automatic determination of groundwater basin storage change, water sustainability to protect from basin overdraft, seawater intrusion and stream depletion, and for in-situ measurement of groundwater contaminant flow rates and directions.
Dr. Kram has been featured in Forbes, is an active member of the National Ground Water Association (NGWA), American Society of Testing and Materials (ASTM Subcommittees D18.21 and E50.02), and the Interstate Technology Regulatory Council (ITRC), and is currently preparing national guidance for vapor intrusion and environmental characterization applications. Dr. Kram co-chaired an ASTM International symposium on continuous soil vapor chemical measurements; served as Editor for the ASTM International book entitled “Continuous Soil Gas Measurement: Worst Case Risk Parameters”; is the recipient of the NGWA’s prestigious Technology Award; and received the ASTM Committee D18 Technical Editors Award.
Kristof’s extensive knowledge in the environmental industry began in 1993, in the water research department of his family business, Laboratories E. Van Vooren. Since then he has fully acquired the firm, and has started multiple other highly successful environmental, remediation and management companies. Kristof holds a Bachelor’s degree in Business Administration as well as his MBA in International Business. With his wide range of knowledge of global affairs, no one knows this business quite like Kristof.
Cliff earned his MBA from the Indiana University of Pennsylvania and a BS in Computer Science from the University of Pittsburgh.
After graduating at the University of Antwerp as a Master in Chemistry (cum laude) and having done an additional year of research in the field of Electrochemistry at the same university to develop his skills further, Tom started his carreer in the private sector in 2004 in the Laboratories Van Vooren, now called Group Van Vooren, to work on remediation projects. In those years he built up an extensive knowledge about both ex-situ and in-situ remediations, and eventually became project leader of several large multimillion dollar projects, including thermal. Although he didn’t forget the importance of working on smaller projects as well. In 2013 Tom was asked to become the Team Manager of TEC, the consultancy company which is part of Group Van Vooren. TEC’s core business includes soil surveys and assessments, risk analysis, remediation projects, and in recent years also more and more asbestos inventories, and not to forget air monitoring assessments (including the automated continuous monitoring known as VaporSafe!).
Paulo Negrão has a degree in Civil Engineering and Ph.D. in Geosciences from State University of Campinas, Brasil (UNICAMP). Negrão is a professor at the post-grad programs at State University of Campinas and SENAC São Paulo. He is also an instructor in the recognized Princeton Groundwater courses.
Negrão was a pioneer in 2011 with the use of mobile laboratories in Brasil for on-site analysis of soil vapor and vapor intrusion. Since 2019, Negrão leads the VaporSafe team in Brasil, offering continuous monitoring services to both local and international consulting firms.
Dr. Blayne Hartman
CEO, Hartman Environmental Geoscience, specializing in laboratory grade field analytical systems and rapid automated vapor analyses
Dr. Hartman has over 30 years of soil gas experience and 20 years of vapor intrusion experience.
Dr. Hartman is a nationally recognized expert on soil vapor sampling, soil vapor analysis, and vapor intrusion. He has provided training on soil gas methods and vapor intrusion to County and State regulatory agencies in over 30 states, many of the EPA regions, the DOD, ASTSWMO, and numerous stakeholder groups and consultants. He was an instructor in the EPA-OUST training, ITRC vapor intrusion training, API petroleum vapor intrusion training and ASTM vapor intrusion courses and has given vapor intrusion training in England, Australia and Brazil. He has written numerous articles on the collection, analysis, and interpretation of soil vapor data, including chapters in five textbooks.
He has participated in technical work groups on soil vapor methods for EPA, CA-EPA, CA Regional Water Boards, County of San Diego, ITRC and ASTM, and has reviewed/edited instructional manuals for the EPA OUST and Superfund groups. Over the past five years, Dr. Hartman has been a contributing author/editor to vapor intrusion and soil gas guidance documents to federal EPA, CA-EPA, San Diego County, ITRC, DOD, API, and more than 25 individual State documents.
He has been involved with six research studies with EPA-ORD on soil gas methods, soil gas temporal variations and indoor air variations in 2012, 2011, 2010, 2009, 2008, & 2007.
Dane has 15 years of experience in the contaminated land investigation industry. His specialized experience lies in the area of vapor intrusion sampling and analysis methods. With a formative 5 years of experience in hydrogeological, landfill gas, and contaminated land assessment, it lead into a focus of the vapor intrusion pathway and gas phase sampling and analysis (10 years). This also includes the area of fugitive emission sampling from coal seam gas related infrastructure and environmental sampling.
Dane is the Principal of CSI Australia and operates a mobile laboratory service for vapor intrusion investigations, primarily for chlorinated hydrocarbon compounds (TCE & PCE) and related daughter products, but also for BTEX (hydrocarbons). Experience in this area of environmental investigation is demonstrated in Dane’s professional affiliations, registrations and certification:
- Australian Land and Groundwater Association (ALGA) – Vapor and Ground Gas Special Interest Group Committee Member: 2016 – current
- The Association for Environmental Health & Sciences Foundation (AEHS, USA)
- Certified Environmental Practitioner (No. 1381) and Site Contamination Specialist (No. SC41147)
