EPA’s Human Exposure Model (HEM) is a probabilistic exposure assessment tool used to estimate how people are exposed to contaminants (often air pollutants, but not limited to them) through different pathways and microenvironments. It is designed to support human health risk assessments by translating environmental concentrations into population exposure distributions for specific pollutants, locations, and demographic groups. HEM uses information on contaminant levels, population characteristics, and time–activity patterns to produce quantitative estimates of average and high-end exposures suitable for regulatory analyses and comparative policy evaluations.
Website providing case studies and resources related to screening assessments of community air quality concerns.
Mapping tool providing information on overburdened communities in New Jersey, as well as information on environmental and public health stressors, and locations of emitting facilities, along with information about violations and incidents.
Utah website to access funding opportunities for air quality projects. Provides a good example of how to set up a resource that can be used by individuals, companies, or local governments to access information about grants, rebates, tax credits, and financing for local projects.
Repository for the Simple Interactive Models for better air quality set of tools. These tools demonstrate fundamental equations to calculate, visualize, and interpret air emissions and pollution. The tools are intended to make links between emissions, pollution dispersion, impacts, and potential solutions more accessible to a wider set of stakeholders. The tools include models as well as primers on different air quality topics.

The HARP Air Dispersion Modeling and Risk Tool, developed by the California Air Resources Board, is Windows-based software that allows users to run air dispersion models and calculate associated health risks from toxic air pollutants. Used primarily in the state’s Hot Spots Analysis & Reporting Program, it integrates modeled concentration outputs with built?in health effect values and demographic data (including a dedicated census database and health database) to support standardized health risk assessments for stationary emission sources in California.
Website providing information on Michigan’s supplemental environmental projects program, which manages environmentally beneficial projects that are not required by state or federal law, but an alleged violator agrees to undertake as part of a settlement of an enforcement action. SEPs are projects that go beyond what is legally required to return to compliance with applicable state and federal laws.
Interactive map that displays information on air quality monitoring, locations of oil and gas wells, ozone and PM2.5 nonattainment areas, permitting and compliance for NSR and Title V permits, and point source emissions.
The Toxics Release Inventory (TRI) Program tracks the industrial management of toxic chemicals. TRI data are reported annually by industrial and federal facilities that meet reporting requirements. EPA makes these data available through multiple online tools, many of which add context to help make the reported data more understandable.
