The purpose of this report is to assess the application of tools to community-level assessments of exposure, health and the environment. Various tools and datasets provided different types of information, such as on health effects, chemical types and volumes, facility locations and demographics, and different formats, such as maps, graphs and tables. Each community case study has a documented environmental or public health concern. This report focuses primarily on the identi.cation of potential issues of concern and the collection of information for them (and the tools and datasets available for these tasks); in contrast, it does not focus on risk rank-ing or prioritization, which falls more into the category of a formal risk assessment.
