Air emissions estimates (CAPs, Hg)

Includes data from EPA's Emissions Modeling Platform (EMP), which provides estimates for emissions of four of the six criteria air pollutants (CAPs): particulate matter (PM2.5 and PM10); carbon monoxide, sulfur dioxide, and nitrogen dioxide (included in the nitrogen oxides category). Ozone (which is formed in the environment by reactions between precursor chemicals but not released directly by polluting facilities) and lead are not included in the EMP.

The data also includes estimates for certain CAP precursors (ammonia, hydrochloric acid, nitrogen oxides and volatile organic compounds) which are chemicals that react with other substances in the environment and lead to the formation of CAPs. Estimates for mercury, which is a hazardous air pollutant but not a CAP or CAP precursor, are also provided.

Toxic releases by chemical & facility (TRI 2022, 2023, 2024)

Data on chemical releases by chemical and facility as reported to EPA’s Toxics Release
Inventory (TRI). Industrial and federal facilities exceeding certain chemical release threshold and meeting certain other criteria are required to report to TRI.

This data set also contains facility-level Risk Screening Environmental Indicator (RSEI) data. Per EPA, a RSEI score is a unitless risk-related result value calculated as the product of a chemical's estimated dose, the exposure route-specific toxicity weight, and the potentially exposed population. RSEI Scores do not describe a level or estimate of risk (such as the number of excess cancer cases), and cannot be used solely to draw conclusions about risk. RSEI Scores are designed to be compared to provide context from a relative risk-related perspective. A computed RSEI Score value that is 10 times higher than another RSEI Score value suggests that the potential for risk-related impacts is 10 times higher.

Risk Management Plan facilities

The Risk Management Program (RMP) rule requires facilities that use extremely hazardous, toxic, or flammable substances to develop and implement a Risk Management Plan. The facilities in this data set are those facilities in EPA's Facility Registry Service (FRS) that link to the Agency's Risk Management Plan (RMP) System.

Percent impaired watershed area (census tracts)

Percentage of watershed area classified as impaired in each census tract as calculated by ATSDR based on 2023 U.S. Environmental Protection Agency (EPA) Watershed Index Online (WSIO) data. An impaired watershed contains waters that do not meet one or more Water Quality Standards (WQSs) even after point sources of pollution (e.g., municipal and industrial discharges) have installed required levels of pollution controls.

Some of these states have not publicly released the relevant data, use a higher blood lead level reporting threshold than the CDC, release data for a smaller age cohort (for example, 0-2 years old) or do not report data by county. Even in states that have published their data, data for some counties may not be available or may have been suppressed for confidentiality reasons.
