Active Landfills

TCEQ Active Landfills from the public ArcGIS server (gisweb.tceq.texas.gov), service Landfills layer 0 'Active Landfills' = 193 currently-permitted MSW (Type 1) and C&D/other (Type 4) landfills statewide. Active-only: TCEQ publishes no statewide closed/historical landfill GIS layer (same as az_deq__landfills); matches the FY24 ~206 active-MSW figure. Single-attribute source (LF). Coordinates LATITUDE/LONGITUDE 100% (TX range); ADDRESS is a comma-delimited cell split deterministically (no libpostal) -> ds_street/city ~77%, ds_zip 75%, ds_state=TX. Fit (coordinates govern). Note: TCEQ MSD_Points/MSD_Polys are Municipal Setting Designations (groundwater program), NOT landfills.

NYSDEC 'Bulk Storage Facilities in New York State' open-data dataset (Socrata pteg-c78n), filtered to closed/historical aboveground petroleum storage tanks (tank_status in 'Closed - Removed', 'Closed - In Place', 'Closed Prior to 03/1991'; program_type='PBS' to exclude Chemical Bulk Storage contamination -- 5,999 CBS rows found in a live pre-filter check; tank_location starting 'Aboveground', matching the current-AST sibling's discriminator). Tank-level grain (one row per tank); 43,732 rows after deduplicating 18 genuine upstream duplicate keys on the program_number+tank_number composite. Sibling to the Verified ny_dec__bulk_storage_aboveground_tanks (current AST) source and the Sourced ny_dec__bulk_storage_underground_tanks_historical (HIST_UST) source -- same dataset, complementary tank_status/tank_location filters.

CIMC Sites

EPA "Cleanups in My Community" (CIMC) national Sites FeatureServer — spans Superfund/NPL, RCRA Corrective Action, Brownfields, Federal Facilities, and OSC removals with per-program institutional/engineering-control indicators. Multi-attribute source: US_INST_CONTROL (Integration 190) and US_ENG_CONTROLS (Integration 189). Distinct from state-level INST_CONTROL sources (e.g. ny_dec__institutional_controls) — this is the national counterpart, no overlap. Composite PK (REGISTRY_ID, SF_SITE_ID, RCRA_HANDLER_ID, BF_PROPERTY_ID, EPAOSC_SITE_ID). Caveat: SF_IC_IND uses an undocumented numeric code domain (1/2/3/4), no published legend found; non-blank treated as "IC tracked" as the most defensible fallback, could overcount ds_US_INST_CONTROL by up to ~516 rows — see .md for detail.

Pfoa Pfos Source Identification Surveys

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.
