Indicator-level percentile and EJ-disparity scores are surfaced on the county page and the state page — they describe wider regional exposure burdens, not effects attributable to a single facility.

What this is not. TRI quantifies releases reported by the facility under EPCRA §313 — not ambient air or water concentrations measured at receptors. We do not attribute individual health outcomes to specific facilities; that exceeds what the data can support.
