Fig. 1: The composition of communities based on cleanup status.
From: Equitable cleanup of Superfund sites leaving no U.S. community behind
a The ten EPA regions with their corresponding states, b Block level comparison of population proportions at the national and regional levels in Superfund host vs. non-host areas by educational attainment, poverty status, Black populations, and Hispanic populations. The red color indicates active cleanup or NPL (National Priorities List), and blue indicates no cleanup sites (non-NPL). Box plots show the median (center line), 25th and 75th percentiles (box edges), and whiskers extending to Q1 − 1.5 × IQR and Q3 + 1.5 × IQR (minimum and maximum), respectively. Sample sizes for each boxplot are given in Table S1, c The proportions of AIANNH (American Indian/Alaska Native/Native Hawaiian), Black, Asian, and Hispanic populations in blocks with no cleanup activities (non-NPL) versus those with active cleanup activities (NPL) across EPA Regions 1 through 10. The red color indicates active cleanup, and blue indicates no cleanup sites. Shapefiles were sourced from the U.S. Census Bureau TIGER/Line® dataset.
