Choctaw, MS
According to the U.S. Environmental Protection Agency's 2023 Toxics Release Inventory, Safe Drinking Water Information System, and Superfund National Priorities List, this Environmental Justice Screening Report covers Choctaw, MS (population 8,172).
This report synthesizes four indicator layers into a single burden score for Choctaw, MS: Toxic Release Inventory (TRI) volume, Safe Drinking Water Act health violations, Superfund National Priorities List presence, and carcinogen-releasing facility density. The county's overall score is 40/100 (grade C+), ranking #452 of 500 counties analyzed in the current dataset.
Underlying values: 3 TRI-reporting facilities releasing 10.6M lbs of disclosed toxics; 1 health-based SDWIS violation across the county's water systems; 0 Superfund NPL sites; and 1 facility reporting carcinogenic chemicals.
Percentile scores compare this county against a national sample of up to 500 counties ranked by the same four indicators. A high burden grade does not by itself establish current health harm, it documents the cumulative regulatory and disclosure footprint drawn from EPA TRI, SDWIS, and Superfund data. Use the indicator breakdown below to see which component drives the score, and drill into the top chemicals and facilities for the underlying Form R filings. This percentile-based score is a different measure than the county profile's fixed-threshold risk score, expect the two numbers to differ.
