Utilizing CSIA to Assess Source and Fate of Contaminants, and the Performance of Remediation Treatments
Wed, March 22, 2023 1:00 PM - 5:00 PM CST
This course aims to present the latest advancement in the applications of compound-specific isotopes analysis (CSIA) and environmental isotopes as forensic tools discern the origin of specific contaminants and characterizing and assessing the fate of different contaminants released in the environment. The potential audience includes environmental professionals, engineers, regulators, and community stakeholders engaged in the management and remediation of contaminated sites.

Speakers
Dr. Orfan Shouakar-Stash
CEO, Isotope Tracer Technologies Inc.
Dr. Shouakar-Stash is an isotope hydro-geochemist with over 20 years of experience. He is the CEO of Isotope Tracer Technologies Inc. (IT2), and an adjunct Professor at the School of Engineering at the University of Guelph, as well as in the Department of Earth and Environmental Sciences at the University of Waterloo.
Research interests:
Dr. Shouakar-Stash’s research interests relate to the development and implementation of isotopic tools in organic and inorganic contaminant investigations, and studies of water quality analysis.
More specifically, he has been actively pursuing the development of using hydrogen, chlorine and bromine isotopes for investigating chlorinated solvents, being a potentially impactful tool for studies related to groundwater contamination.
Sasha Tom Hart, MSc
Technical and Strategic Consultant
Sasha is a contaminated land and water resource consultant with over 25 years of experience and has delivered successful projects in industrial, urban, mining and agriculture areas throughout more than 15 countries. He has a MSc. in Environmental Technology and Water Management from Imperial College (United Kingdom) and this year is completing his PhD in Hydrogeology at University of São Paulo, Brazil. His research includes isotopic uses for source, commingled plumes and remediation applications, based on the development of conceptual models even for complex settings (such as fractured bedrock and megasites). This has contributed to the rehabilitation or areas, safe use of soil/groundwater, several published papers, a book about Forensic Isotopes, presentations and post-graduate courses (he teaches at University of São Paulo and SENAC in Brazil). He has also supported the setup and development of NICOLE LA (Latin America Network for Soil and Groundwater Management), INSOP (International Network on Soil Pollution of FAO, UN) and ReNIF (Rede Nacional de Isótopos Forenses – Brazilian Network of Forensic Isotopes).
David F. Alden, P.E. (NC)
Manger, Technical Services at Tersus Environmental
David serves as the Manager of Technical Services at Tersus Environmental, where he is a dedicated professional with extensive experience in environmental engineering and technical services. In this pivotal role, David is instrumental in fostering innovation and excellence within the realm of environmental solutions. He provides crucial technical support for Tersus' biotechnology-based solutions, specializing in the management of complex environmental liabilities and cost reduction for site closure.
David's academic journey includes earning a degree in Civil Engineering from Universidad de las Americas-Puebla, Mexico, and a master's degree from Joseph Fourier University in Grenoble, France. With this diverse educational background, he brings a unique perspective to his position.
A key aspect of David's work revolves around the development of innovative technologies for restoring groundwater and soil in challenging sites. He has authored three patents on reductive bioremediation and in situ chemical reduction, with US Patent 11,123,779 B2 titled "Method and a Chemical Composition for Accelerated In Situ Biochemical Remediation" being a notable contribution. Additionally, he has eight pending patent applications for groundwater contaminant remediation.
Managing the companies Compound-Specific Isotope Analysis (CSIA) projects, David showcases his commitment to staying at the forefront of industry advancements by applying cutting-edge techniques to assess environmental contaminants. David leverages his expertise in CSIA to provide a quantitative means for differentiating reaction pathways—shedding light on the intricate processes of abiotic and biotic degradation. This not only enhances our understanding of environmental challenges but also paves the way for more targeted and effective solutions.
David also employs molecular biologic tools to assess remediation performance. By integrating cutting-edge techniques, he ensures that our environmental solutions are not only efficient but also sustainable in the long run.
