The availability of basic data is necessary, but not necessarily sufficient, to accomplish environmental justice objectives. The challenge is to verify the existence of disparate impacts (e.g., disparities correlated with race and income) and to identify where they occur, who is impacted, and who is responsible. To answer correctly such questions, it is necessary to translate data into accessible, meaningful information. The Risk-Screening Environmental Indicators (RSEI), a unique and advanced computer tool developed by EPA’s Office of Pollution Prevention and Toxics, has the capability to translate toxic chemical release data into more meaningful risk-related information required by researchers and activists to analyze disparate impacts by race and income and to focus properly risk-reduction efforts in communities.
