(Archived as of December 2024) – The ITRC QUEST Knowledge Map was an interactive tool for navigating ITRC’s environmental guidance documents and resources, allowing users to filter through ITRC’s vast library based on concise subjects. The Knowledge Map presented a “roadmap” of where to find key environmental topic and concept information within the ITRC guidance and resources library, and is organized by the Assessment and Remediation phases of environmental cleanups.

This toolkit is a companion to the ITRC Microplastics Guidance to help regulators and others explain issues surrounding microplastics to a variety of audiences. The toolkit includes general information on outreach along with fact sheets, presentations and other outreach items aimed at different audiences.

This document includes a brief overview of risk communication, the steps in developing a communication plan and stakeholder outreach activities, an overview of risk communication concepts, applies these principles in case studies, and includes various tools to facilitate risk communication plan development.
