National environmental context for any US county: EPA Toxics Release Inventory reporting facilities (historical hazardous-release reporters) and EPA SDWIS public drinking-water systems, composed verbatim with provenance, per-facility/system detail links, and verify links to event-history databases (National Response Center spill reports, PHMSA hazmat incidents). Reports, not incidence - never a safety verdict about an area or water supply.
