Sustainable remediation emerges as an innovative platform for the remediation of contaminated areas, with sustainability increasingly assuming a global priority for companies, governments and society in general. Remediation solutions that include sustainability concepts offer many advantages in the environmental, financial and social spheres.

The process of migrating volatile chemical compounds in the vapor phase from a subsurface source into the existing buildings on the surface is known as vapor intrusion. Based on the recognition of the relevance of this route of exposure, several regulatory environmental agencies around the world request its inclusion in the approach of risk analysis to human health for potentially contaminated areas.

CSM is typically applied at contaminated sites to identify environmental, financial, and social factors that are likely to determine possible reuse scenarios for the area. Advanced methods of site characterization and traditional approaches to site characterization are contrasted for this technique. An evaluation of the methods available to evaluate the information and the role of the quantity and quality of the data resulting from the CSM and, ultimately, the selected remedies is important.

A major challenge in the environmental area has been the difficulty of graphically and spatially representing issues related to a particular investigated case without requiring large amounts of time between collection, processing, interpretation, analysis and subsequent representation for clients, managers and the public. The exchange of experiences and case studies, highlighting the benefits of using ArcGis’ sophisticated statistical interpretation, modeling and geoprocessing tools, especially in the design of CSM, can contribute to the development of quality material and better interpretation of environmental problems, resulting in assertiveness in decision-making processes.

With a strategy based on resource valuation and shaped by a territorial vision, circular economy frameworks could open new perspectives in contaminated sites and brownfield management. Using tools developed in urban metabolism studies, the main goal of this WG is to deconstruct the value chain while braking down silos, to then build a more circular design capable of maximizing positive externalities for both the problem owner and local communities. With practical models and genuine decision-support tools, NICOLE would be the perfect “testing ground” to promote a more inclusive and holistic vision, based on the 3R’s (reduce, reuse and recycle).

In view of the growing need for the use of mathematical models in decision-making processes in the area of ​​contaminated area management, and also relying on the CETESB / SP guidelines presented in the Board Decision No. 38/2017, the Modeling Working Group seeks to encourage dissemination of concepts associated with computational mathematical modeling tools and applications; empower the Brazilian technical community, reducing its dependence on importation of foreign experience; and ensure autonomy of professionals in the interpretation of model results.
