Aqueous film-forming foam use indicator

Florida fire training facilities assessed by FL DEP for AFFF (aqueous film-forming foam) use — 29 facilities. Direct match to the Chubb Description. Authoritative list = FL DEP 'Fire Training Facility Site Assessments' page; each facility enriched with structured address + WGS84 coordinates from FL DEP's ERIC PFAS Sites ArcGIS layer (CLEANUP_SP layer 4, joined by ERIC_SITE_ID) where present, else from the facility's DEP detail page.

NYSDEC's three PFOA/PFOS "potential source site identification" facility surveys (2017, FOIL-released PDFs, originally Excel workbooks): a facility-identification survey of manufacturing/industrial facilities (Survey 1, prefix MFG), a Class B fire-suppression-foam usage survey covering airports, military/DoD facilities, bulk storage facilities, and fire departments (Survey 2, prefixes AIR/MIL/BSF/FDP), and a fire-training-centers survey (Survey 3, prefix FTR). Each surveyed facility answered Yes/No/Unknown questions about current or former use, storage, manufacture, or disposal of PFOA/PFOS (or, for the Class B foam surveys, Class B firefighting foam, which does not always contain PFOA/PFOS). fetch.py parses all three PDFs (no ruled table lines; reconstructed from pdfplumber word positions) into one row per surveyed facility -- 2,633 rows total, the full raw survey population including non-responding facilities. conform.py adds ds_PFAS = "true" for any facility answering Yes to at least one question -- the "potential PFAS source site" population, 833 of 2,633 facilities.
