KEYS TO SUCCESSFUL IN-SITU REMEDIAL DESIGN AT BROWNFIELDS SITES: A COMPREHENSIVE APPROACH UTILIZING DESIGN VERIFICATION TESTING AND FLUX TRACER TOOLS
Abstract: Remediation of contaminated sites, specifically brownfields, requires a strategic approach that ensures the remediation's effectiveness while minimizing costs and time to closure. This presentation explores the keys to successful in-situ remedial designs at brownfields sites.
The technical approach involves establishing a fundamental understanding of the site conceptual model (CSM) and remedial goals. A comprehensive site investigation is essential in determining the extent and nature of contamination. This is followed by the selection of appropriate remediation technologies, including physical, chemical, and biological methods.
Pre-application evaluation, including design verification testing (DVT), is crucial in ensuring the effectiveness of the remediation design. The methods and procedures implemented in DVT, along with an overview of the results, will be discussed. Furthermore, Flux-Tracer, a novel in-well monitoring tool, will be introduced to identify contaminant mass flux within the subsurface. Thus, allowing for the design of a remediation system that targets the pathways of contaminant migration.
Application is vital to all in-situ remedial approaches. An overview of our experience successfully implementing in-situ projects across the country, with a focus on lessons learned, will be provided.
Finally, a case study demonstrating the successful implementation of our in-situ remedial design approach at a brownfields site will be presented. The case study will highlight the effectiveness of our approach in remediating a contaminated site while minimizing costs and time to closure.
In conclusion, the keys to successful in-situ remedial design at brownfields sites are a strategic approach, including a thorough site investigation, the selection of appropriate remediation technologies, pre-application evaluations, and thoughtful application. By implementing these key factors, in-situ remedial design projects can achieve their goals and ensure a safer and more sustainable environment.
