Pollution Analyst turns complex federal environmental and health data into accessible, location-based insights. It brings together information from the EPA, air-quality monitors, CDC PLACES, and Census data to help people understand pollution trends and the communities affected. Users can explore states, counties, cities, industrial facilities, public water systems, and Superfund sites.

The platform covers industrial chemical releases through the Toxics Release Inventory (TRI) and greenhouse-gas reporting, criteria air pollutants, hazardous-air cancer risk, drinking-water violations, and community health rates. Rankings compare counties, cities, and facilities across measures such as fine particulate pollution, cancer risk, and releases to air, water, and land. Facility and county pages also show long-term trends, while pollution indicators are paired with demographic data and environmental-justice context.

Pollution Analyst explains its sources, metrics, thresholds, and caveats through published methodology and data-source information, supporting transparent, reproducible analysis. Its data is drawn from public-domain federal sources and updated according to each source’s schedule. The service is free to use and requires no account.
