E!10016 Application of Tracer Technology for Characterization of Chemically Contaminated Areas

A tracer method which was originally developed for measurement of remaining oil in petroleum reservoirs will be modified and used to measure the concentration and the extent of some contaminants (non-aqueous phase liquids - NAPLS - such as the case of petroleum products) in soils. Further, data gained by tracer application on selected contaminated sites will be compared and combined with more conventional approaches of contamination description. The project is a cooperation between a Czech SME, Teramed, and the Department for Tracer Technology at Institute for Energy Technology (IFE) in Norway. One contaminated site in the Czech Republic (Patek) which is suitable for piloting of the new approach to be developed in this project will be thoroughly examined with respect to their geological and chemical properties (Teramed). Concurrently, at IFE, tracers will be qualified for use in realistic matrixes by extensive testing against real field samples and the physical conditions which describe this (these) site(s). Initial and tentative protocols for site characterizations and subsequent remediation are prepared prior to first tracer field test at the pilot site(s). Further on, the result of each field test provides input for establishing a final protocol for this type of environmental contamination monitoring and provides a basis for efficient remediation and decontamination services.

- Several tracers were qualified to estimate the amount and presence of choloroethylen mixtures in contaminated soils. - A Field test was succesfully performed in the case study Patek. - The use of tracers has demonstrated to be a feasible tool for studying contaminated areas With non-aqueous phase liquids (NAPLs) - A huge potential can be foreseen for the Application of tracers in environment , where other aspects might be assessed such is the contamination transport, conectivity of water reservoirs, fractures, and water flow directions.

This project will create a service encompassing a more complete approach to describe and remediate non-aqueous phase liquid (NAPL) spill and contaminations. A tracer method which was originally developed for measurement of remaining oil will be modified and used to measure the concentration and the extent of dense NAPLs in deep geological environments. Further, data gained by tracer application on selected contaminated sites will be compared and combined with more conventional approaches of contamination description. The project is a cooperation between a Czech SME, Teramed, and the Tracer Technology Group at Institute for Energy Technology (IFE) in Norway. One or more contaminated sites in the Czech Republic which are suitable for piloting of the new approach to be developed in this project will be thoroughly examined with respect to their geological and chemical properties (Teramed). Concurrently, at IFE, tracers will be qualified for use in realistic matrixes by extensive testing against real field samples and the physical conditions which describes this (these) site(s).
