epa-contaminated-site-screener
Screen addresses against EPA Superfund, RCRA, TRI, UST, LUST, Brownfields, and more. Identifies contaminated sites near your property, scoring hits at ASTM E1527-21 search distances for Phase I ESA due diligence.
Instructions
Phase I ESA & Environmental Due Diligence: EPA Database Search. Environmental due diligence by address: an environmental database report over EPA Superfund/NPL, RCRA CORRACTS/TSD/generators, TRI, UST, LUST, Brownfields, NPDES, AIR, TSCA and RMP, scored at ASTM E1527-21 search distances, plus on-site Superfund and AUL boundary checks. No API key. Reads live from the official government source. Store page: https://apify.com/malonestar/epa-contaminated-site-screener
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| mode | No | "assets" (default) runs a multi-database Phase I ESA-style regulatory-records screen on your addresses/coordinates — one billable row per nearby EPA-listed site (across Superfund, RCRA, TRI, UST, LUST and Brownfields). "inventory" instead dumps the raw list of EPA SEMS/Superfund sites for the states you pick — one billable row per site. Example: "assets". | |
| assets | No | Locations to screen against EPA contaminated-site databases. Each item is EITHER {"address": "...", "label": "..."} (geocoded via the free Census geocoder) OR {"lat": <number>, "lon": <number>, "label": "...", "state": "<2-letter, OPTIONAL>"}. The "state" hint is no longer required with lat/lon — Superfund is now also screened spatially against the EPA FRS SEMS point layers, which need no state. Supplying "state" additionally pulls that state's full Envirofacts SEMS roster for wider non-NPL coverage. One dataset row (one billable check) is produced per site hit found within the radius; assets with no hits return a single "clear" row. If EVERY asset fails input validation the run FAILS and nothing is billed. Example: [{"lat":39.8037,"lon":-104.9986,"state":"CO","label":"Denver industrial parcel (lat/lon input)"},{"address":"5980 Lipan St, Denver, CO 80221","label":"Denver industrial parcel (address input)"}]. | |
| states | No | 2-letter US state codes (e.g. ["CO", "NJ"]) whose EPA SEMS/Superfund site records to list. Required when Mode = inventory. Ignored in assets mode (state is derived automatically per-asset). | |
| onlyNpl | No | Inventory mode only: when true, keep only sites currently on (or part of) the National Priorities List — the actual Superfund program sites. When false, include all SEMS site statuses. Default false. Applied by default if omitted: false. | |
| astmMode | No | Assets mode only. Adds ONE extra "astm_summary" row after each asset's normal rows, scoring this actor's databases against the ASTM E1527-21 Sec. 8.2.1 standard search distances. The refined table splits RCRA into its three real ASTM line items — CORRACTS 1.0 mi, TSD 0.5 mi, LQG/SQG/VSQG generators 0.25 mi — resolved from EPA ECHO, alongside NPL 1.0 mi, SEMS-CERCLIS 0.5 mi, LUST 0.5 mi, UST 0.25 mi and Brownfields 0.5 mi (TRI has no ASTM search distance and is excluded). Results come as flat CSV-safe columns (astm_npl_flag, astm_rcra_corracts_flag, ...) plus a nested object, with an astm_refined_verdict. Automatically widens the underlying fetch to 1 mile; your normal per-hit rows still respect radiusMiles unchanged. Screening aid only — not a substitute for an ASTM E1527-21 Phase I ESA. Default false. Example: true. Applied by default if omitted: false. | |
| programs | No | Which EPA program databases to include. The six defaults: SUPERFUND (NPL/SEMS), RCRA (hazardous-waste handlers, now classified into CORRACTS / TSD / generator), TRI (Toxics Release Inventory), UST (underground storage tanks), LUST (leaking USTs), BROWNFIELD (ACRES/FRS). Four additional opt-in programs come from the SAME EPA ECHO response at no extra upstream call: NPDES (Clean Water Act discharge permits), AIR (Clean Air Act permitted sources), TSCA (incl. PCB handlers), RMP (Risk Management Plan chemical-accident facilities). Leave EMPTY to screen the original six only — that keeps row counts and cost identical to previous versions. Ignored in inventory mode. Example: ["SUPERFUND","RCRA","TRI","UST","LUST","BROWNFIELD","NPDES","AIR","TSCA","RMP"]. | |
| maxResults | No | Safety cap on total dataset rows produced across the run: max site hits emitted (assets mode) or max SEMS site rows (inventory mode). Applied by default if omitted: 1000. | |
| radiusMiles | No | Distance from each asset within which EPA-listed sites are counted and reported across all selected programs. Accepts fractional miles (0.1-50) so you can screen at the ASTM E1527-21 standard search distances directly: 1.0 mi (NPL / RCRA CORRACTS), 0.5 mi (SEMS-CERCLIS, RCRA TSD, LUST, Brownfields), 0.25 mi (registered UST, RCRA generators). Default 1 mile covers the widest ASTM distance. Example: 1. | |
| onlyWithCoords | No | Inventory mode only: when true (default), drop SEMS records with no latitude/longitude. Coordinate coverage varies sharply by state — measured 2026-07: 3% of Texas SEMS records carry coordinates, 16% California, 48% Colorado, 60% New Jersey, 77% New York, while NPL-track records are ~96-100% geocoded everywhere. Set false to see the full raw roster including un-mappable rows. Example: true. | |
| includeBoundaries | No | Assets mode only. Runs two extra point-in-polygon queries per asset to answer "is this property ON a Superfund site?" (on_superfund_site, superfund_site_name, superfund_epa_url) and "is it inside a published EPA Superfund institutional-control / activity-and-use-limitation boundary?" (institutional_control_flag, institutional_control_description). These are true boundary intersections, not distance-to-centroid. Note EPA publishes ~2,114 NPL site polygons but only ~165 IC polygons nationally, so a false IC result means "not inside a published federal Superfund IC", NOT "no AUL exists". Adds no dataset rows and no billing. Default true. Example: true. | |
| maxHitsPerProgram | No | Assets mode only: cap on the number of nearest site hits reported per program per asset (keeps output and billing bounded near dense industrial areas). The nearest sites are kept. Default 50. Range 1-1000. Example: 50. | |
| strictDataCompleteness | No | Assets mode only. Reserved for callers that must not accept partial coverage. Regardless of this setting, every row already carries programs_screened / programs_failed / data_complete, and an asset whose databases ALL failed is reported as result_type "error" — never as a "clear" result. If every database fails for every asset the run FAILS so nothing is billed. Default false. Applied by default if omitted: false. |
