If you are interested in participating this half day short course, please contact directly the convener Lorenzo Sacchetti (lorenzo.sacchetti@caruscorporation.com).

This short course has been prepared to provide basic information for the selection and the design of innovative remediation technologies. Workshops have been designed in order to develop a remediation scenario for the presented classes of pollutants technologies. We will provide to attendees some field data (geological cross sections, drilling logs, soil and groundwater contamination results, ….) from real sites and we will build together the site conceptual model and the remediation alternatives. We will preliminary design the remediation and we will calculate the cost under different assumptions in order to show how it is possible to drive the assessment/remediation phases to maximize results reducing costs.

Preliminary program includes the followng lectures:


In situ Chemical Oxidation (ISCO) and In Situ Chemical Reduction (ISCR)- ISCO/ISCR field of application will be discussed. We will present the different available oxidizers and reducers (Fenton, Permanganate, Ozone, Persulfate, zero valent iron), their characteristics (single component, multi components, ...) and their applicability with respect of Contaminants of Concern (COCs), geology, soil chemistry and Natural Oxidant demand. An overview of distribution technologies (in wells injection, direct push injection, recirculation, soil mixing,...) will be provided too.

In Situ Chemical Oxidation: New developments and directions - ISCO techniques are under continuous development in order to overcome distribution issues and to limit Natural Oxidant demands. The presenter will review innovative ISCO approach with some details about field scale testing and results

ISCO/ISCR Field applications - we will present several case studies form sites in Europe and in the USA. For each site will be shown the conceptual model including contamination horizontal and vertical distribution (for different contaminants including CFCs and recalcitrant chlorinated compounds) and the technology selection process. Drawings and pictures from fieldworks will explain carried out activities and achieved results (including lessons learned from unexpected issues).

Reductive Dechlorination (anaerobic bioremediation) for Halogenated Hydrocarbons - After a description of the reductive dechlorination phenomena we will discuss the technology applicability with respect of field evidences of existing dechlorinative pathways by autochthonous bacteria. Different natural and engineered substrates (HRC, CAP18, emulsionated oils, ...) will be presented along with distribution options. Technology and substrate limitations will be presented. Detailed design criteria for integrated ISCO-bio processes will be presented along with full scale projects case studies.

Coupling ISCO and ISCR with bioremediation for sustainable and effective remediation: CAPISCO and EZVI technologies - ISCO/ISCR are complementary technologies than can be successfully applied in treatment trains for source and plume control and remediation. ERT will provide information about the CAPISCO process including permanganate and vegetable oil (CAP18) injections. Carus will present and discuss EZVI a product developed by NASA based on Zero Valent Iron emulsionated with vegetable oil. Case studies will be provided for both the technologies.
