CSIA to Assess Contaminant Remediation

Date and Time: Thu, May 28, 2020 11:00 AM - 12:00 PM EDT

Presenters:  Dr. Sara Herrero and Dr. Clara Torrentó


Compound Specific Isotope Analysis (CSIA) provides unique information at each stage of a site remediation project. Traditional strategies, based on concentration analysis and hydrogeochemical data, are in many cases insufficient for a robust site diagnosis and for planning technical decisions. CSIA complements conventional data, providing additional insights and further lines of evidence to support management decisions. The combination of different diagnosis techniques results in a more efficient remediation, saving time, effort and cost.

CSIA helps solve several questions that contaminant remediation managers need to answer: are multiple sources contributing to the contamination? Is natural attenuation occurring? What is the rate of degradation? Are intermediates being degraded? Can contamination rebound or displacement be identified? Is the remediation working? What is the remediation efficiency?

This presentation will cover the principles and fundamentals of Stable Isotope Analysis for environmental applications. We will provide some case studies from MAiMA research group, in which multi-element CSIA (i.e., analysis of different elements within the same molecule) has been applied to answer the questions pointed above.

Dr. Sara Herrero Martín
Dr. Sara Herrero is the Scientific project manager and Innovation promoter of MAiMA Research Group, at the University of Barcelona (Spain). She holds a BS degree in Environmental Sciences, and both MS and PhD degrees on analytical chemistry from the University of Salamanca. She has more than 10 years of experience on stable isotope analysis for environmental applications, including 6-years at international research centres in Germany. She worked for 5 years, as project manager and Post-Doc researcher, at the Department of Isotope Biogeochemistry from the Helmholtz Centre for Environmental Research – UFZ (Leipzig), where she led her own research line focused on the development and validation of new methods to improve the limits of detection of Compound Specific Isotope Analysis (CSIA). Then she worked for 1 year as the Head of the Core Facility “Stable Isotopes” at the Leibniz-Centre for Agricultural Landscape Research – ZALF, Müncheberg (Germany). From September 2015 she works at MAiMA research group, where she has gained experience on the knowledge transfer of scientific research to environmental consultancies and regulators. She has participated, as project manager, in more than 20 R&D&I projects focused on the application of stable isotopes for the fingerprinting and assessment of remediation treatments at polluted sites.

Dr. Clara Torrentó
Dr. Clara Torrentó is a Marie Curie Fellow at MAiMA Research Group, at the University of Barcelona (Spain). She holds a BS degree in Geology from the University of Zaragoza, and a PhD degree on Earth Sciences from the University of Barcelona. Her research interests are focused on the use of isotopic tools to assess the fate of contaminants in groundwater and contaminated soil, with a strong focus on experimental studies at laboratory and field scale to characterize natural and induced contamination attenuation processes. She has more than 15 years of experience in the development and application of isotopic methods to industrial (e.g., chlorinated solvents, petroleum hydrocarbons) and agricultural (e.g., nitrate, pesticides) pollutants. She has gained international experience through a 4-years postdoctoral fellowship at the Centre for Hydrogeology and Geothermics of the Université de Neuchâtel (Switzerland). Her current MSCA project is focused on demonstrating the applicability of multi-isotopic techniques to identify sources, and to evaluate the fate of pesticides in the environment and to assess the efficiency of natural and induced attenuation strategies. Apart from research projects, Clara has participated in more than 20 third-party funding projects for the transfer of knowledge to private companies and regulatory sectors.
