PFAS chemical indicator

EPA Chemical Data Reporting and legacy Inventory Update Reporting manufacture/import records filtered to chemicals on EPA Substance Registry Service list 490, the strict TSCA §8(a)(7) PFAS list. The integrated product emits one row per facility, chemical, and reporting cycle across 1998–2024, with normalized address and available coordinates plus the preserved unified reporting fields. Confidential chemical identifiers without a public CAS number cannot be matched to the PFAS list, and coordinate coverage is limited to cycles that publish coordinates.

Annual CSV product for RY 1987-present containing facility, geography, parent, industry, chemical, release, transfer, recycling, energy-recovery, treatment, production-waste, and activity-ratio data from TRI Form R and Form A. Prior-year files may be revised. Coverage is limited to TRI-covered facilities, sectors, chemicals, and reporting thresholds.

EPA's Fifth Unregulated Contaminant Monitoring Rule (UCMR 5) occurrence data, filtered to Texas public water systems. A federal, EPA-run PFAS + lithium monitoring program covering community water systems and large non-transient non-community systems during a single 12-month window between 2023 and 2025. Sourced from EPA (not TCEQ) because TCEQ's own Drinking Water Viewer was confirmed to have zero PFAS sample data loaded for any Texas system. Yields 214,143 analyte-sample rows (206,808 PFAS-analyte rows + 7,335 lithium rows) covering 1,153 distinct Texas PWSIDs, with 6,346 quantified PFAS detections.
