Science & Data
Built on the science governments rely on.
Every number you see in Pollution Profile comes from real environmental data and peer-reviewed methodology — not estimates or black boxes.
How the data works
We combine official government datasets with validated algorithms so you get a clear, accurate picture of your environmental exposure.
Air Quality
EPA NowCast algorithm with 12-hour lookback and dynamic weighting for EPA-compliant AQI. Data from 1,906 US and 6,000+ global monitoring stations.
Facility Emissions
EPA Toxics Release Inventory and RSEI health risk model (chemical toxicity × release amounts × dispersion). 770+ chemicals, plume modeling via HRRR wind data. Data back to 1987.
Water Quality
169,561 public water systems via EPA SDWA/SDWIS: contaminant summaries, detection records, violation history, and service area boundaries per system.
Protected Lands & Nature Access
309,662 parks and protected areas (PADUS). Proximity and accessibility scored for every US census tract.
Global Historical PM2.5
ACAG/Copernicus satellite data, worldwide coverage, 1998–2023 (26 years). H3 spatial indexing for any location on earth.
Environmental Legal Cases
819+ real federal environmental tort cases (CourtListener), AI-enriched with chemicals involved, health effects, exposure pathways, outcomes, and damages. Actively updated.
Pathways & exposure routes
Every pathway pollution can take — tracked.
Pollution travels from industrial sources through air and water, then enters your body through multiple routes. We map each step of that journey.
Pollution sources & transport
Stack Emissions
Industrial smokestacks & exhaust vents
Fugitive Air
Uncontrolled releases from industrial sites
Air Transport
Airborne migration of pollutants downwind
Water Release
Discharge into rivers, lakes & coastal waters
Water Transport
Downstream spread through waterways
Groundwater
Leaching into underground aquifers
Human exposure routes
Inhalation
Breathing contaminated outdoor & indoor air
Drinking Water
Consuming water from contaminated sources
Ingestion
Exposure through food grown in affected soil
Dermal Contact
Physical contact with contaminated materials
Health outcomes — linked to exposure
Cumulative exposure across these pathways is associated with increased cancer risk, respiratory disease, cardiovascular conditions, and developmental impacts. We give you a lifetime record of your exposures so you and your doctor can understand the full picture.
Data sources
Every source is publicly available and used by researchers, regulators, and courts.
