EQUITY INGEST PENDING FOR THIS GEOGRAPHY

Hartford County County, CT (no Census block groups within 3 miles — falling back to containing county).

Demographic shares, national-percentile rankings (PM2.5, ozone, NO₂, diesel particulate, lead-paint risk, NPL/RMP/TSDF/NPDES proximity, drinking-water non-compliance), and EJ disparity scores will render here once the EJScreen-clone ingest completes for this geography. Why this section matters →

Source. EPA Toxics Release Inventory · retrieved 2026-05-07. Reporting year 2024. TRI is a federal public-domain dataset under 17 USC §105.

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.
