Roane, TN
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 Roane, TN (population 54,403).
According to EPA TRI, SDWIS, and Superfund NPL extracts, Roane, TN has an environmental burden score of 60/100 (grade D+), ranking #123 of 500 counties in this sample. Underlying disclosure counts: 9 TRI facilities releasing 4.3M lbs, 22 health-based SDWIS violation rows, and 1 Superfund site. The score is a percentile of federal disclosure footprints, not a diagnosis of current community health harm.
This report synthesizes four indicator layers into a single burden score for Roane, TN: 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 60/100 (grade D+), ranking #123 of 500 counties analyzed in the current dataset.
Underlying values: 9 TRI-reporting facilities releasing 4.3M lbs of disclosed toxics; 22 health-based SDWIS violations across the county's water systems; 1 Superfund NPL site; and 6 facilities reporting carcinogenic chemicals. Of the 1 Superfund site in this county, 1 is actively listed on the NPL.
Transparent derived index from EPA TRI / SDWIS / Superfund extracts: not an official EPA rating. Each of up to 500 counties is percentile-ranked on four rates (toxic lbs per capita 35%, health-based SDWIS rows per water system 25%, Superfund sites per 100k residents 20%, carcinogen-facility share 20%), then weighted. Population-less counties take a neutral 50th percentile on the per-capita indicators. See methodology.
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.
