The hazardous waste proximity indicator is reflective of the total count of hazardous waste facilities in each block group within 5 km of the average resident in a block group, divided by distance, calculated as the population-weighted average of blocks in each block group. Hazardous waste facilities are defined as Resource Conservation and Recovery Act (RCRA) handlers that are either operating TSDFs from RCRA or reporting LQGs from the 2019 BR.
