NYSDEC Brownfield Cleanup Program (BCP) sites — the BCP slice (program_type=BCP) of NY Open Data's "Environmental Remediation Sites" dataset (Socrata c6ci-rzpg). 1,833 distinct brownfield sites statewide. The raw dataset is denormalized one row per site×operable-unit×contaminant (~67.7k BCP rows); fetch.py aggregates server-side via $group=program_number to one clean row per site. Each site is real property whose redevelopment may be complicated by hazardous waste/petroleum/contaminants — matching Chubb's BROWNFIELDS definition. Carries facility name, address, locality, county, ZIP, WGS84 lat/lon, and owner fields.

Florida DEP ArcGIS layer of individual sites with executed Brownfield Site Rehabilitation Agreements, including site identity, address, county, district, acreage, agreement date, coordinates, remediation status, and supporting document links. This is the site layer, distinct from the broader Brownfield Areas designation layer.

Illinois EPA brownfields inventory of redevelopment and assessment sites, including program identifiers, property location, funding and investigation details, completion date, acreage, and contaminant category.

South Carolina SARR public records for non-responsible-party voluntary cleanup contracts in the Brownfields program, including amendments and inurements; responsible-party contracts and EPA grant-funded assessments are excluded.

Wisconsin DNR BRRTS bulk facility-activity data for contaminated-property assessment, investigation, cleanup, and redevelopment activities. This source uses the public tab-delimited bulk export and focuses on ERP, LUST, and VPLE activity records; spill and no-action-required records are excluded from the candidate scope.

Open and closed Wisconsin Environmental Repair Program cleanup activity points from BRRTS.

Statewide BRRTS bulk-export subset of reported leaking underground storage tank activities, open and closed.

Official City of Los Angeles open-data product exposing LADBS Certificate of Occupancy records through dataset 3f9m-afei, an anonymous SODA API, and downloadable full files. Rows carry CofO number, issue date, latest certificate status and status-effective date; assessor book/page/parcel, legal-description and street-address keys; the related PCIS permit; permit and building facts; and, where populated, an `occupancy` value explicitly defined as the approved use for the structure. Public metadata identifies LADBS, official provenance, CC0 1.0 dedication, a weekly committed refresh, and data updated 2026-08-17; the checked live data contained 128,551 rows with CofO issue dates from 2005-01-26 through 2026-08-14. This is a certificate-record dataset, not proof of present operations: 82.89% of checked rows have null occupancy, no separate certificate-type or successor identifier is emitted, and current interpretation must be pinned to `cofo_issue_date`, `status_date`, `latest_status`, and the dataset-level source vintage.

Coordinated historical NYC Open Data schema family comprising Bureau of Fire Prevention Inspections (ssq6-fkht), Active Violation Orders (bi53-yph3), and Building Summary (nvgj-hbht). Anonymous SODA and CSV access support arbitrary NYC BIN, BBL, and premises-address retrieval. The modules preserve account-level latest inspection status, open violation-order codes/descriptions, and building-level sprinkler/standpipe descriptors and open-violation counts. All are frozen snapshots: the source database was decommissioned, no new data will be added, and rows were last updated on 2019-03-07. The Source must never be represented as current compliance, completed correction, current resistance, or system operability evidence.

NDEP Bureau of Water Pollution Control's public BWPC_ActivePermits ArcGIS layer, restricted to currently issued Major NPDES and Minor NPDES permits (PERMITSTAT='PRMTISS'). It excludes the separate Groundwater permit category, terminated NPDES records, and facilities covered only by stormwater general permits; the filtered endpoint returned 93 records during harvest and publishes facility addresses and coordinates.

Permits issued by the Department of Environment (DOE) from January 1993 to December 31, 2011 and by the Department of Public Health (CDPH) since January 1, 2012. This dataset also includes tank permits issued by CDPH on behalf of the Office of the Illinois State Fire Marshall (OSFM). On January 1, 2012, the DOE was disbanded and all its inspection, permitting, and enforcement authorities were transferred to the CDPH. The public Chicago Data Portal provides API access and downloadable exports, with daily updates.

Florida DEP CHAZ (Compliance Hazardous Assessment Zone) MapServer layer 5, filtered to GENERATOR IN ('SQG','CES'). Covers 23,496 statewide Florida facilities classified as Small Quantity Generators (SQG, 100-1,000 kg/month RCRA hazardous waste) and Conditionally Exempt Small Quantity Generators (CES, <100 kg/month) from the county SQG Assessment, Notification and Verification Program. Supplies both HAZ_WASTE and HW_GEN attributes: every record is both a hazardous waste generator (HAZ_WASTE) and a county HW generator survey participant (HW_GEN). Fetched via paginated ArcGIS REST/JSON with WGS84 geometry; street address and coordinates are fully populated (100% fill rate).

Official City of Chicago open dataset, anonymous SODA API, and full-file download of Department of Buildings violations issued from January 1, 2006 to present. Records are updated daily and include the violation code, corresponding authority description and ordinance text, violation and status dates, inspection context, address, a property-group lot key, and coordinates. The City cautions that the records are historical and informational, may include liable and not-liable cases, do not necessarily reflect current building/property condition, and should not be used as the authoritative outstanding-enforcement record for real-estate transactions.

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.

TCEQ HB 2537 (1993) Closed & Abandoned UNNUMBERED Municipal Solid Waste Landfill Inventory = 2,772 old/closed unnumbered MSW landfills operated before permits were required, plus unauthorized landfills and illegal dumps — the HIST_LF attribute for TX. Single statewide Excel file (msw-unum-texas.xlsx) on the TCEQ MSW data page; NOT in any TCEQ GIS service or on data.texas.gov Socrata. Distinct from active permitted landfills (tx_tceq__active_landfills) and from closed NUMBERED/permitted facilities (msw-closed-facilities-texas.xls, not used — those had permits). Workbook row 1 is a provenance note; header is row 2 (fetch.py skips row 1). LOCATION (free-text locator) → ds_street 96.9%; LATIT_DD/LONGI_DD → ds_lat/lon 88.9% (309 rows carry a 0.0 null-island placeholder, blanked in conform, not fabricated); ds_state='TX' const; no city/zip cols. Fit (ds_street>90%). Count 2,772 ~6% under Tier-C predicted band (the '4,200' was the 1990s COG-located figure).

Public Maine DEP point inventory of closed and historical municipally owned or operated landfills and town dumps, with site identity, location, closure, description, and summary details. It excludes active or licensed solid-waste facilities.

Oregon OSFM Community Right-to-Know hazardous-substance reports filtered by OSFM to Storage Container = "Above ground tank" and released under public-records request PRR4042. The delivered XLSX contains 6,643 report-by-chemical rows; the verified integration rolls these up by Facility ID to 3,549 active, latest-report facility locations statewide, with address and OSFM-provided coordinates.

Bounded first-party CDE API family for monthly Crime Trend summaries at national, state/territory, and reporting-agency levels. Responses provide offense and clearance counts and rates, comparison series, population and participating-population denominators, population coverage, and UCR data-currency pins. The coordinated offense, state/territory, and agency lookups provide the identifiers and current offense menu required to address the summaries. Violent and property trends combine SRS with NIBRS submissions converted/summarized for trend presentation; aggregate displays may include FBI estimates for incomplete or nonreporting agencies. This Source is not a crime-risk model, premises prediction, incident-level NIBRS product, county-total product, or proof that unreported crime did not occur.

Fixed annual July point-in-time snapshots of operating business locations from 1997 through the most recently completed year, currently July 2025, with one record per operating location per snapshot and persistent `infogroup_id` linkage across years.

ADEQ's statewide ArcGIS layer of recorded Declaration of Environmental Use Restriction and Voluntary Environmental Mitigation Use Restriction sites, including institutional or engineering controls and site locations.

Official daily-updated NYC Open Data dataset of certificates of occupancy issued through DOB NOW from March 2021 onward. Records resolve by BIN, street address, borough/block/lot and BBL, and publish DOB job filing, certificate application and C of O identifiers, request and issuance dates, issued status, filing type and sequence, dwelling-unit count, and geographic reference fields. This is an issued-certificate index: it does not publish approved use, occupancy group, floor/area schedules, effective or expiration date, document URL, or an explicit current/superseded flag. Absence must not be interpreted as evidence of present use, illegal occupancy, safety, or noncompliance.

Statewide inventory of current and historical dry-cleaning and laundry locations potentially associated with chlorinated solvents.

Statewide BRRTS listing of dry-cleaner facilities regardless of remediation status, with location and activity-detail links.

EPA ECHO public national facility-level compliance and enforcement data delivered through live REST services, generated query CSVs, the ECHO Exporter full ZIP, and coordinated national download dictionaries. Covers CAA, CWA/NPDES, RCRA, SDWA, and federal enforcement records; this bounded Source excludes TRI release quantities and other emissions inventories.

Plant-level subset of the annual Form EIA-860 Schedule 2 workbook for power plants reporting an ash impoundment, including whether the impoundment is lined and its operating status alongside plant identity and location.

Living global disaster-country flat table, 1900-present, updated weekly and available as a complete XLSX after registration. Commercial entities can buy a documented annual licence.

TCEQ Emergency Response Spills — the named Texas Open Data (Socrata) dataset xagr-a3x2 (spill notifications to the TCEQ Emergency Response Division, keyed by incident tracking number). 46,043 incidents, one row each. conform.py: ds_street from deliv_txt(+deliv_2_txt) with a phys_loc_desc_txt fallback, ds_city from near_city_name, ds_state constant 'TX', ds_zip from loc_zip_txt; ds_lat/lon from lat_dec_coord_num/long_dec_coord_num. Same reachable Socrata portal as tx_tceq__operating_dry_cleaner_registrations.

New York remediation sites with engineering controls in place. From NYSDEC 'Environmental Remediation Sites' (data.ny.gov Socrata c6ci-rzpg, denormalized across BCP/VCP/ERP/HW/RCRA). Filtered to control_code='Environmental Easement' OR control_type='ENG' = 853 distinct sites (deduped to program_number). Site name, address, coordinates. Single-attribute: ENG_CONTROLS. Pure institutional-control sites (deed restriction/notice only) excluded — they belong to the separate AUL attribute.

New York State DEC Environmental Remediation Sites dataset published on the NY Open Data portal via the Socrata SODA API. Filtered to program_type='HW' (State Superfund / Inactive Hazardous Waste Disposal Sites), this Source provides site name, address, county, municipality, site classification, and program status for all HW-program sites statewide. Coordinates are included for the majority of sites. Fetched as paginated JSON and conformed to the ds_ scheme with ds_HWS presence boolean.

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.

Official statewide database of voluntarily reported land-subsidence incidents maintained by the Florida Geological Survey. The current public ArcGIS point layer emits report identity, reported event and revision dates, verification code, coordinates and location precision, PLSS geography, report source/name, reported dimensions and site observations, repair/property-damage indicators, comments, and four related coded tables for topography, possible triggers, pre-collapse indicators, and land use. It is not a sinkhole-certification or hazard-prediction product: most incidents were not field checked, cause and many locations are unverified, and reporting is not mandatory or complete. The service exposed 4,443 records when checked; a latest reported-event date of 2026-08-01 was observed, but no fixed update cadence or database-wide currency/version field is documented and historic-moment queries are unsupported.

Commercial, non-contributory global POI API. Place Search retrieves ranked places for buyer-specified circles, rectangles, or geocodable localities; Get Place Details retrieves a stable FSQ Place by fsq_place_id. One Source includes coordinated Pro and paid Premium returnable fields.

Public global disaster-notification product exposed through standing RSS/CAP feeds and a documented REST API. The public feed emits event/episode identity, event interval, point, affected countries, tropical-cyclone maximum-wind severity, modification time and event version. It is automatic indicative event evidence, not a sovereign disaster declaration and not an insured-loss product.

Open worldwide machine-coded news-event metadata beginning with the GDELT 2.0 raw stream on 2015-02-18. The coordinated product comprises the 61-field Events table and 16-field Mentions table, published as 15-minute tab-delimited ZIP files and queryable in Google BigQuery. Events encode two actors, a CAMEO action, three geographies, media-coverage measures, ingest time, and first source URL; Mentions encode each article mention, extraction confidence, article position, source identity, tone, and translation metadata. It is a media-derived event index, not a verified incident-observation database. Event-table legacy coverage measures are fixed to the first 15-minute update; later discussion is emitted as new Mentions rows rather than revisions to the Event row.

Paid web service converting buyer-supplied addresses to coordinates and place IDs and coordinates or place IDs to formatted addresses. Coverage and result quality vary by country and location.

Commercial US property lookup returning parcel, ownership, transaction, location, and building-characteristic data by address or property identifier.

Event-level downloadable data file covering more than 200,000 domestic and transnational terrorist incidents worldwide from 1970 through 2020, with no incident file for 1993. The latest page citation is the 2022 release. Raw data are obtained after a brief active download form. Ordinary terms permit non-commercial research and analysis; commercial use requires an additional agreement. Collection stopped after partial 2021 work for lack of funding, so there is no promised current release cadence. START may correct records when new documentation appears and has no obligation to update.

Commercial bearer-token API for location-first U.S. negotiated rates.

Commercial GET /hail API for continuously updated hail history at an arbitrary U.S. or southern-Canada point selected by coordinates or street address. The linked public schema emits location metadata, requested date range and radius, plus hail-occurrence dates and daily maximum hail size. Current first-party pages conflict on archive depth (the schema says history to 2012, the insurance page says seven years, and the retail report page says 2018 to present), so no fixed archive start is asserted.

Georgia EPD's July 2025 statewide inventory of 453 sites listed under the Hazardous Site Response Act, with site identifiers, location, listing date, class, investigation or cleanup funding code, and links to site summaries.

Combined historic and then-current Georgia landfill GIS database through 1999, including sites closed before permits were required.

Pennsylvania DEP's public Hazardous Site Response Actions List is an annually refreshed SSRS CSV report derived from eFACTS and covering hazardous-site response work since 1988. The integrated product filters the report to HSCA initiations and emits 1,554 response-action × environmental-medium × substance rows across about 489 sites. It preserves facility identity, owner/operator, address, coordinates, Pennsylvania Priority List dates, response actions, media, and contaminant columns, while prepending normalized location fields and an HSCA indicator.

NHC's official post-storm best-track data product for Atlantic cyclones from 1851 and Northeast/North Central Pacific cyclones from 1949. Two basin files are delivery partitions of one HURDAT2 product. Records provide native six-hourly and selected asynoptic positions, status, winds, central pressure, wind radii, and landfall/peak identifiers.

Commercial event intelligence product for impactful wildfires and bushfires. ICEYE combines SAR observations, building footprints, auxiliary fire data, machine learning, and expert analysis to deliver event-scoped building-level vector results. The documented damage output locates assessed structures by latitude/longitude points or building footprints and assigns a binary structural-damage classification of destroyed or undamaged. The product also includes an Esri monitoring application using active-fire locations/perimeters, hotspots, building footprints, and populated urban centres. Results are updated during qualifying events; service availability is currently documented for the United States, Australia, and Canada and is not universal event coverage.

Active Indiana NPDES-permitted wastewater discharge facilities, including permit terms and receiving waters.

South Carolina subset of the federal National Response Center (NRC) oil/chemical/hazmat incident-report archive (USCG). Full archive 1990-2025, filtered to LOCATION_STATE='SC' from the per-year NRC FOIA workbooks (INCIDENT_COMMONS sheet). 12,596 reports. Provider divergence: Integration 114 is keyed to sc_des, but SC DES's Oil & Chemical Emergency Response division takes reports by phone and publishes no public spill dataset (no data.sc.gov dataset; gis.des.sc.gov Emergency_Response folder has only a physiographic map; SC DHEC AGOL org has only aggregated count layers), so the authoritative downloadable source is the federal NRC (us_uscg_nrc). Each record: incident date, type, cause, description, location address/city/county/zip, and (rarely) lat/lon. NRC posts initial, unvalidated reports.

Statewide industrial-facility search results for facilities with Wisconsin industrial storm-water general permit coverage.

New York environmental-remediation sites whose NYSDEC control_type is INST, including institutional controls such as environmental easements, deed restrictions, decision documents, and environmental notices.

Versioned global multi-agency tropical-cyclone best-track collection. NCEI merges recent and historical agency tracks and publishes v04r01 as complete and subset CSV, NetCDF, and shapefile downloads. The product includes best and provisional tracks; release/version identity is v04r01 and the landing page supplies its update schedule. It is not a substitute name for native HURDAT2.

Iowa landfill and land-disposal inventory filtered from Iowa DNR's Solid Waste Facilities layer to Municipal Landfills and Other Landfills. It includes active and inactive or closed sites with facility identity, program and permit status, address, county, coordinates, and permit dates.

Official City of Los Angeles open-data product exposing soft-story-related permit and permit-application records through a dedicated Socrata catalog asset (nc44-6znn), API, and downloadable files. It contains parcel/address keys, permit identifiers, issue and status dates, permit status/type/category, work description, building attributes, and related permit-party fields. The product is limited to City of Los Angeles permit records selected into this soft-story view; it is not the mandatory programme's full building inventory. Metadata commits to weekly refresh, but the data was last updated 2023-05-22 and the latest row dates are 2023-05-19, so consumers must pin results to that source vintage. Permit issuance, `CofC Issued`, `Permit Finaled`, or absence of a record must not be interpreted as current structural safety, retrofit design adequacy, or complete ordinance compliance without an official status definition and newer authority evidence.

Wisconsin registry of current and historic landfill and waste-disposal activity locations.

Public EDMS index of asbestos demolition and renovation notification lifecycle documents, filtered to Asbestos media and ADVF subtype and joined to LDEQ Agency Interest facility records for location context.

Daily public record of Louisiana Voluntary Remediation Program properties carrying institutional controls, deduplicated to one row per LDEQ Agency Interest property from the portal’s manual CSV export.

Florida DEP STCM "Leaking Aboveground Storage Tank Site Locations" report — the authoritative, purpose-built dataset for facilities with an aboveground tank and a recorded discharge. Fetched per-county across all 67 counties (POST cid+query_cid, same session-cookie pattern as the sibling fl_dep__regulated_ast/fl_dep__regulated_ust reports) and aggregated from 6,518 tank-substance-component rows to 1,473 distinct facilities by FAC_ID. Latitude/Longitude are published directly on the report in unsigned DMS format and converted to decimal degrees by fetch.py (no ArcGIS join needed). FDEP's own PLACEMENT column splits every facility into "AST Only" or "AST UST" (also has an underground tank) since STCM cannot attribute a discharge to a specific tank — both values qualify for ds_LAST=true. Single-attribute source: LAST.

Illinois EPA statewide ArcGIS layer of leaking underground storage tank incidents, including site identifiers, location, responsible project contacts, and resolution-related dates.

Statewide GIS registry of leaking underground storage tank incidents and sites.

All leaking underground storage tank incidents published by DC DOEE through the DC GIS feature layer, from historical records through the present. Each row represents a distinct case number and includes open, closed, no-further-action, administrative-closure, and related statuses; the live endpoint returned 1,952 records on 2026-07-13.

TCEQ public ArcGIS layer "LPST Points" — leaking petroleum storage tank incidents statewide (open + closed). One row per incident, keyed on LPST_ID (site-level RN can repeat across multiple incidents at the same site). ds_state hardcoded to TX per the tx_tceq__state_superfund precedent — layer has no explicit state column and is definitionally Texas-only.

NY DEC's shared Environmental Remediation Sites Socrata dataset (c6ci-rzpg), filtered via a facility-name substring heuristic (MGP/MANUFACTURED GAS/GAS WORKS/GAS LIGHT) since DEC publishes no dedicated MGP dataset or program_type flag. 225 program-enrollment rows (HW 140/VCP 64/BCP 20/ERP 1) across 186 distinct physical MGP sites statewide; the raw undeduplicated count was chosen over the site-deduplicated count to avoid inventing a cross-program dedup key DEC doesn't provide.

Statewide extract of MPCA solid-waste disposal areas filtered to municipal solid waste, ash, industrial waste, demolition debris, and closed-landfill site types, with facility, permit, status, address, and coordinate details.

Nationwide bulk data listing coal and metal/non-metal mines tracked by MSHA from January 1, 1970 to the present, including mine identity, status, ownership, location, commodities, staffing, and physical and operational characteristics.

Gauge responses include location metadata, observed stage/flow status with units, valid time and flood category, configured action/minor/moderate/major flood thresholds, and observed stage-flow time series; forecast data are also present but are not the observation capability asserted here.

Ongoing global historical database of related tsunami source-event and observed runup-location tables, spanning 2100 BC to the present. It emits event source/time/location, cause, validity, magnitude/intensity, maximum water height and historical effects plus runup observation location, arrival/travel time, measurement type, water height, horizontal inundation and location effects. Reporting is heterogeneous and is neither a completeness claim nor prospective hazard. Pin DOI 10.7289/V5PN93H7, retrieval date/query and API schema.

Standing archive of NHC/CPHC advisory forecast track, cone-of-uncertainty and watches/warnings bundles, with related wind-field files, published as downloadable shapefile/KML packages by storm and advisory. This Source preserves forecast-at-issuance evidence and is distinct from final HURDAT2 post-analysis. Geometry remains in source files and is not flattened into speculative scalar Features.

It publishes station and observation identifiers, UTC timestamps, coordinates, temperature, wind, gust, precipitation, present-weather, and embedded quality codes through NCEI Access Data Service and bulk Global Hourly files.

A separately named Version 2 station summary product publishing hourly, daily, and monthly observations in station-year CSV files and monthly summary forms. It is derived from NCEI station datasets but has its own documented 125-column CSV schema, metric bulk files, U.S.-focused station coverage with limited U.S. Air Force locations abroad, and standing per-station/year plus all-station archive access.

Free governmental U.S. bulk CSV database of NWS-documented significant weather events. Event-detail and location files identify episodes/events, event type, begin/end time, reporting source, hail or wind magnitude and magnitude type, flood cause, and linked event locations. These are reported/certified event records, distinct from radar estimates.

Ongoing global historical database of significant volcanic eruptions from 4360 BC to present. An event qualifies if it caused fatalities, caused moderate damage (about USD 1 million or more), had VEI 6+, generated a tsunami, or was associated with a significant earthquake. HazEL emits event timing, volcano identity/location, VEI, fatality agents, direct eruption effects, combined associated effects, comments, and association IDs. It is not the complete GVP catalogue, a current-alert feed, or a prospective hazard model.

Downloadable Iowa DNR workbook listing facilities with individual NPDES or state operation permits authorizing wastewater discharge to Iowa surface waters. It includes facility and owner details, permit identifiers and classification, location, treatment, design-flow, and operator-certification information; general-permit authorizations are excluded.

One contracted HailStrike OneSite report family, not separate Sources for Basic, Lite and Full tiers. A buyer can order an unrelated site report directly, and the publisher offers high-volume orders for hundreds or thousands of locations. Public materials and samples emit location-attributed hail dates, estimated hail size, a defined 1–10 Derived Hail Index, storm movement, wind-gust history, NEXRAD station provenance, report issue/version and verification identifiers. Public pages conflict on history depth (five years, ten years, or storms since 2011), so no universal archive start is asserted. The product does not establish tornado or tropical-cyclone outputs.

A downloadable IHS Excel snapshot of open-dump sites on Indian lands, with site identity, operational and review status, condition, land tenure, fencing, health-threat assessment, waste contents, coordinates, and surface area.

OSMRE's national e-AMLIS product identifies abandoned mine land problem points reported by states, territories, tribes, and federal programs. The integrated ArcGIS product emits WGS84 coordinates, AMLIS and ArcGIS identifiers, problem type, funding program, planning unit, problem area, USGS quadrangle, county, reclamation status, and a normalized abandoned-mines indicator. It provides no street-address fields.

Statewide inventory of active permitted Tennessee landfills with class, identity, operating status, address, county, and coordinates.

National point inventory of major petroleum bulk, breakout, and marine terminals, including location, operator, terminal type, commodities, transport modes, and capacity. This is a terminal inventory, not a complete registry of all aboveground storage tanks.

EPA's PFAS Analytic Tools republishes National Response Center spill reports through the PAT_Spills ArcGIS layer. This integrated source filters Material_Involved for AFFF or FOAM and emits incident identifiers, dates, quantities, materials, narratives, responsible parties, causes, water impacts, raw and geocoded locations, and relative-location descriptors. Its conformed output adds normalized address and coordinate columns plus an AQUEOUS_FOAM_NRC indicator on every selected row.

NPDES permittees with PFAS discharge monitoring or effluent limits, sourced from EPA's PFAS Analytic Tools 'Discharge Monitoring Reports' layer (ArcGIS FeatureServer layer 15, PAT_Discharge_Monitoring_Reports), itself built from ICIS-NPDES DMR data already restricted upstream to PFAS-family parameters. The raw layer is 96,155 monitoring-event rows (facility x outfall x PFAS parameter x year); fetch.py aggregates client-side to one row per unique NPDES_Permit_Number (1,110 permittees), rolling up distinct parameters monitored, whether any parameter carries an effluent limit, most recent monitoring year, and outfall count. No street address or ZIP is published by this dataset; location is carried by lat/lon (99.91% fill).

EPA's PFAS Analytic Tools 'Federal Sites' layer (PAT_Federal_Sites, FeatureServer layer 13), the full unfiltered nationwide roster of federal facilities (DoD, DOE, NASA, DOT, federal Superfund) with known/suspected/pending PFAS assessment. 762 sites nationwide. No street address exists upstream; near-complete coordinate coverage. A sibling Source, us_epa__pfas_federal_sites_tx, queries the same layer filtered to Texas only for a different Attribute (AQUEOUS_FOAM) -- neither supersedes the other.

Texas AFFF sites (AQUEOUS_FOAM) = 35 federal (DoD/DOE) installations with PFAS presence (from Aqueous Film Forming Foam use), from EPA's PFAS Analytic Tools 'Federal Sites' layer (PAT_Federal_Sites, FeatureServer/13) filtered to State='TX'. Sourced federally because TX TCEQ maintains NO dedicated AFFF inventory (confirmed: no PFAS/AFFF layer on gisweb.tceq.texas.gov, none on data.texas.gov). Same source family as the Verified us_epa__pfas_afff / us_epa__pfas_npl_sites / us_epa__pfas_tsca sources. Coordinate-only (installation centroids; layer has no street/city/zip): ds_lat/lon 100% (all in TX bbox) → Fit; ds_state='TX' constant. Composition: Air Force 12, Army 13, Navy 7, DOE 3; PFAS_Presence Known 16 / Suspected 14 / Pending 2 / blank 3. Within predicted band 15-85. DoD-only — excludes civilian airport/fire-training AFFF sites (TX publishes none).

EPA PFAS Analytic Tools 'Industry Sectors' layer (PAT_Industry_Sectors, layer 3 of the public PFAS_Analytic_Tools_Layers ArcGIS FeatureServer) -- facilities with federal CAA/CWA/RCRA permits operating in industry sectors that literature review indicates may handle or release PFAS, per EPA's ECHO methodology. This is the live feed backing the interactive PFAS Analytic Tools dashboard's Industry Sectors tab. 714 facilities as of 2026-08-12, dominated by Part 139 airports (536) plus smaller NAICS/SIC-driven categories (waste management, chemical manufacturing, printing, metal coating, etc.). Note: this live layer is significantly narrower than the ~120,000-facility figure cited in EPA's marketing description of the tab's methodology -- see the Source .md for full reconciliation.

EPA's PFAS Analytic Tools Superfund layer identifies National Priorities List sites with reported PFAS detections. The integrated product filters the ArcGIS layer to NPL_Site=Yes and emits 464 site records with EPA identifiers, names, addresses, coordinates, NPL status, site type, program context, and profile links. It preserves the 18 fetched ArcGIS attributes and adds seven normalized location and PFAS indicator columns.

Curated statewide BRRTS listing of activities where PFAS contamination has been confirmed.

Illinois EPA entry-point-level PFAS sampling results from its statewide investigation of community water supplies, including measured analytes, detection indicators, units, water-system identifiers, and coordinates.

EPA's PFAS Analytic Tools 'Toxics Release Inventory' Waste Management layer (PAT_TRI_Waste_Management, FeatureServer layer 5) -- TRI Form R Section 8 waste-management line items for PFAS and other TRI-listed fluorinated organics. 1,895 rows / 127 unique TRI facilities nationwide, reporting years 2015-2024. Picked over the sibling On-Site Releases layer (layer 6), which is the more literal match but currently returns almost no live data (EPA-side refresh gap).

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.

ADEQ's "AQD Permits" ArcGIS FeatureServer layer (owner adeq_gisnp) — a facility ("Place") level registry of Arizona Department of Environmental Quality Air Quality Division permitted sources, statewide except Maricopa, Pima, and Pinal counties (which run their own delegated air-permitting programs). Each of the 408 rows is a permitted facility classified via STATE_CLAS as Major Source, Minor source, or Synthetic Minor (two sub-variants) — matching the Chubb Description's major (>100 tons) / minor (<100 tons) criteria pollutant threshold almost verbatim. Regenerated daily per ADEQ's own Hub listing. No address fields are published (only LATITUDE/LONGITUDE); ds_street/ds_city/ds_zip are always blank while ds_lat/ds_lon are 100% filled.

MDE’s statewide list of individually tracked permitted discharge and outfall locations.

TCEQ's Point Source Emissions Inventory, drawn from the State of Texas Air Reporting System (STARS): an annual survey of chemical plants, refineries, electric utilities, and other industrial sites that meet the emissions-reporting threshold under 30 TAC 101.10. Each row is a (regulated entity, reporting year) observation carrying the company/account identity, site location, and site-wide annual tons-per-year emissions for the EPA criteria pollutants (CO, NOx, Pb, PM, PM10, PM2.5, SO2, VOC). The multi-year state-summary workbook (2010-2024, 28,867 rows) is fetched in full and covers only the AIRS Attribute for Texas.

The integrated Envirofacts API product emits nationwide site identifiers, names, address and jurisdiction fields, limited coordinates, NPL and non-NPL status, federal-facility and Superfund Alternative Approach indicators, archive dates, standardized address columns, and a SEMS_ARCHIVE flag.

Illinois EPA registry of Site Remediation Program No Further Remediation letters, aggregated to one row per site and joined to site location data, with engineered-barrier and institutional-control indicators.

Illinois EPA bulk export of active and inactive voluntary remediation projects enrolled in the Pre-Notice Site Cleanup Program and Site Remediation Program.

Official Mandatory Soft Story Program dataset with one property row keyed by assessor block, lot, parcel number and address. It publishes the four programme tiers and a current programme status string, plus point geography and source/portal timestamps. It does not publish a separate engineering deficiency, retrofit permit identifier, completion date, or present-resistance certification; status values such as “Work Complete, CFC Issued” must remain authority programme statuses rather than derived safety findings. Portal metadata says weekly change and publication frequency. The live dataset contained 4,945 rows and a uniform data_as_of of 2025-07-31T01:02:58.134 when checked, so the stated weekly cadence and observed currency must both be retained.

South Carolina permitted solid-waste facility list, including active and post-closure landfills, composting, recycling, transfer, processing, and incineration facilities.

Utah DEQ Division of Waste Management and Radiation Control hosted ArcGIS point layer of solid-waste facilities statewide, with facility identifiers, names, street and city location details, and coordinates.

Open SPC historical severe-report database compiled from NWS Storm Data, currently covering U.S. tornadoes 1950–2025 and hail/damaging wind 1955–2025. Annual/full-period CSVs and SVRGIS path/initial-point shapefiles are one product family. Tornado files include raw state/county segments and de-segmented actual tracks. Magnitude means F/EF rating for tornado, inches for hail, and knots for wind with measured/estimated gust/sustained qualifier. Dated releases can correct and reprocess records, so retain release metadata. It is not a complete census, radar footprint, or building-impact dataset. SVRGIS creates a 0.0001-degree offset endpoint when no real endpoint was reported.

Statewide GIS inventory of environmental spills handled by IDEM emergency response.

Public Ohio EPA Emergency Response dataset of reported incidents since May 17, 2017, with spill site coordinates and reported and recovered product details. Reports are incidents as reported and are not necessarily confirmed spills.

Pinned to final validated 2025 data published 2026-07-30, with final series 1979-2025 and 2024-specification mappings. Northern Ireland, non-injury/unreported crashes, narratives, and ordered multi-event sequences are excluded.

FDEP STCM "All Facilities and LatLong Information" report, all 67 counties, joined against the DWM_STCM ArcGIS layer for signed WGS84 coordinates. Full lifetime tank-facility registry, all statuses (OPEN/CLOSED/ABANDONED). One row per FAC_ID, verified zero duplicates. Deliberately independent of the 3 Verified fl_dep sources on the same STCM system (regulated_ust, regulated_ast, leaking_ast) — none covers the full any-status roster; this Source accepts overlap rather than reopening Customer-signed-off deliverables. Same pattern as ny_dec__pbs_tanks (Integration 264).

Florida DEP STCM (Site Tracking and Compliance Management) ArcGIS MapServer Layer 5 — drycleaning facilities. Filtered to active facilities only (FAC_STAT IN OPEN, OPEN-NSH, OPEN-SH) and drycleaning facility types (FAC_TYPE IN 1, 3, 6: drycleaner, dry drop-off, dryclean-related other).

Open, event-specific satellite-derived building-damage point-vector releases for selected disaster areas. Current releases expose GDB/SHP full files with building-point geometry, observation date and sensor, confidence, field-validation status, damage class, settlement, event code and notes. Release pages pin pre/post imagery, publication/version and caveats. Coverage exists only where UNOSAT has produced an activation/release; it is not a global arbitrary-address lookup and findings are preliminary, visible-structural-damage observations rather than field inspections.

Open longitudinal building-point damage assessments issued under UNOSAT's explicit Comprehensive Damage Assessment name. The current Gaza release carries fourteen observation snapshots with sensor date, sensor code, confidence code and damage class, thirteen change/status fields, final grouped class, field validation, notes, administrative geography and event code. It is a separately named and materially different schema family, not a release instance of the standard 11-column product.

The API supports event, site, and location-based retrieval of high-water marks and returns event/site identifiers, coordinates, flag and survey dates, surveyed elevation, vertical datum, mark quality, height above ground, and riverine/coastal environment.

EPA's national UST Finder ArcGIS FeatureServer (Releases layer), server-side filtered to Maryland releases reported before 1999-01-01 — the frozen pre-1999 slice of MDE's legacy 'Recovery Sites Database,' distinct from MDE's live OCP case system (already covered by md_mde__ocp_case_search). 4,543 rows, no auth, paginated via resultOffset/resultRecordCount. Note: this data overlaps with the separately-scoped us_epa__ust_finder source — both draw from what is verifiably the same underlying UST Finder Releases dataset (published via two distinct-but-data-identical ArcGIS items), and this Maryland/pre-1999 slice is fully reproducible by filtering us_epa__ust_finder's fetched output. Kept as an isolated single-attribute source per the developer's explicit decision (Integration 216) rather than folded into the multi-attribute us_epa__ust_finder source.

EPA's national UST Finder ArcGIS FeatureServer (Releases layer, item US_Underground_Storage_Tank_2019), server-side filtered to State='New Jersey' — 16,816 leaking underground storage tank (LUST) release records covering New Jersey's full release history regardless of status (4,672 Open, 12,144 No Further Action/closed). This is a NJ-filtered slice of EPA's UST Finder Releases dataset, not a source published directly by NJDEP; NJDEP's own DataMiner LUST portal was investigated first and abandoned due to an hCaptcha wall with no programmatic bypass. Note: this data has been verified to overlap byte-for-byte (identical LUST_ID sets) with the separately-scoped us_epa__ust_finder source, which draws from a newer-but-data-identical ArcGIS item (UST_Finder_Feature_Layer_2). Kept as a standalone single-attribute source per established developer precedent (Integrations 216/294) rather than folded into the multi-attribute source.
