KEY PERSONNEL

Mr. Kakarla is responsible for overall project design, field implementation, project management, regulatory reporting, and field oversight. He has managed over 200 projects and serves as the contact for technical issues and field implementation issues. Mr. Kakarla is also in charge of laboratory research aimed at optimizing treatment efficiencies for both soil and ground water contamination. Additionally, he performs literature reviews detailing ongoing oxidative research and acts as a liaison between ISOTEC and various academic institutions currently studying oxidative technologies in an effort to optimize ISCO treatment technologies. He has taught ISCO courses, hosted workshops, published in peer-reviewed journals, and chaired sessions at numerous conferences. Prior to ISOTEC, Mr. Kakarla served as a research and teaching assistant at Washington State University and completed his thesis on chemical oxidation of sorbed, hydrophobic contaminants in surface soils using in-situ Fenton-like processes. Mr. Kakarla has a Master of Science in Environmental Engineering from Washington State University and Bachelor of Technology (Honors) in Civil Engineering from Indian Institute of Technology (IIT), Kharagpur.

Mr. Temple has over six years of international remediation experience in Germany, Denmark, Japan (numerous job sites) and the Caribbean; lending both his technical support and job site supervision expertise. He is qualified to conduct site evaluations and assist in the design and implementation of in-situ remediation systems using chemical oxidants such as modified Fenton's reagent (MFR), sodium persulfate and sodium/ potassium permanganate, along with a wide array of bioremediation treatments.

Mr. Eilber has worked on ISCO remediation projects at former and active military installations, active refineries, chemical facilities, retail and commercial dry cleaning operations as well as active and decommissioned gasoline stations throughout the United States, Canada and Japan.

In addition, Mr. Geckeler focuses his technical efforts on the in-situ treatment of organic compounds and metals, multiple-phase extraction, and ISOTEC’s patent-pending PFAS remediation technology. Grant Geckeler is a named inventor of two U.S. patents for remediation technologies.

Prior to joining ISOTEC in 2020, Mr. Geckeler was an officer and director at GEO Environmental Remediation Company, where he oversaw thermal remediation and in situ treatment projects across North America, Australia, Europe, and Asia. Mr. Geckeler is based in Southern California, and he works from ISOTEC’s Tustin, CA office. When he is not engaged in his projects at ISOTEC, Grant enjoys mountain biking and surfing with his two children.

At ISOTEC, Mr. Pittenger brings a deep understanding of owner perspectives on environmental risk and liability having spent nearly a decade offering leadership and management of a large portfolio of site liabilities across the eastern United States for a Class I railroad. He defined the remediation strategy and ultimate closure for numerous properties, and provided his expertise to multiple internal departments. He also has a strong background in remediation as a former consultant and treatability lab manager. He designed, built, and performed bench studies, field pilots, remediation systems, and multi-stage field events across North America, in Europe and the Middle East.

Mr. Caldicott has designed and carried out numerous laboratory experiments and field treatment programs. Mr. Caldicott is an owner of ISOTEC Remediation Technologies and a key part of the management team that operates both companies. He is responsible for generating and maintaining business relationships and opportunities, technically evaluating client's sites, remedial option appraisal, oversight, final review of treatment designs and proposals, and project management. In addition, Mr. Caldicott identifies and evaluates new synergistic products and services that may be incorporated into the company's portfolio and is the principal negotiator in business deals. He has helped to steer ISOTEC to adopt non-core technologies such as chemical reduction, bioremediation, soil mixing (chemox and ISS), Gas Thermal Remediation (GTR), C3 Technology, BOS 100®, CAT 100™ and BOS 200® Trap and Treat® Products, and a revolutionary PFAS technology that takes advantage of the inherent properties of the compounds for remediation.

Prior to his association with ISOTEC, Mr. Caldicott established, and ran, the North American office of an Australian company that developed reagents for remediating metal contaminated media. Mr. Caldicott was responsible for all technical and scientific treatment evaluations which included remedial design and project management. Mr. Caldicott has served as a field technician and GIS analyst. He has also served as a research assistant at Yale University and completed a thesis on the investigation of bauxite residue for use in the remediation of trace metal contaminated media.

At ISOTEC, Mr. Dombrowski is a technical leader for design, implementation, and management for a full suite of remediation technologies and supports activities to incorporate developing and innovative technologies and approaches to support ISOTEC projects and customers.

Mr. Dombrowski’s remediation experience includes chlorinated solvents, petroleum hydrocarbons, 1,4-dioxane, and manufactured gas plant sites. He has direct experience designing and/or implementing a broad range of in-situ groundwater technologies including chemical oxidation, bioremediation, zero valent iron, injectable activated carbon, soil vapor extraction, and thermal remediation. Mr. Dombrowski also has experience with PFAS investigations, design and build for water/wastewater projects, and research experience in arsenic and metals geochemistry.

In addition, Mr. Dombrowski is an Adjunct Lecturer at Tufts University in Medford, MA. He received a Bachelor of Science in Environmental Engineering and Masters Degree Environmental Engineering from Manhattan College in New York City. Mr. Dombrowski is registered Professional Engineer in Massachusetts and Connecticut.

He is qualified to conduct site evaluations and assist in the design and implementation of in-situ remediation systems using chemical oxidants such as modified Fenton's reagent (MFR), sodium persulfate and sodium/ potassium permanganate, along with a wide array of bioremediation treatments.
