FRTR Spring 2024 General Meeting: Artificial Intelligence and Machine Learning to Optimize Site Remediation

Sponsored by: Federal Remediation Technologies Roundtable

The FRTR Spring 2022 General Meeting explored applications of artificial intelligence (AI) and machine learning (ML) concepts to site cleanups. Technology advances in robotics, unmanned systems, and analysis of large data sets to support site characterization and remediation were reviewed. Projects seeking to advance use of AI/ML and support remedy decisions were presented. Potential benefits, risks, and limits of deploying AI/ML technologies were identified.

The FRTR 2024 Spring General Meeting provides an opportunity to share progress and results of recent AI/ML projects providing advanced contaminant plume characterization and predictive modeling, and improved cleanup efficiency. The meeting highlights site-specific case studies where AI/ML has substantially enhanced remedial decisions, remedy implementation and performance monitoring, and reduced needs for extensive sampling. Discussions during the meeting seek to provide remedial project managers and technical staff with information and best practices for deploying AI/ML technology.
