Environmental Data and Tools for Scientific Inquiry
Below you can find some of EPA's environmental databases and scientific tools to learn more about chemical risks and conditions of the environment, whether locally or for the whole nation.
These databases are primarily scientific in nature; other databases of compliance information or regulatory status can be found on EPA's Databases and Software page.
- Test Methods and Guidelines
- Environmental Emissions and Releases
- Environmental Fate, Measurements, and Exposure
- Health and Environmental Effects and Assessment
- Risk Management and Treatment Technology
- Geographical Information
- Environmental Test Methods and Guidelines: EPA has prepared a number of guidelines for measuring chemicals in the environment and for testing the effects that chemicals can cause.
Environmental Emissions and Releases
- AIRSweb: access to key measurements of air pollution used to assess the Nation's air quality including air quality measurements from 4000 air monitoring sites across the nation for the past five years and air pollutant emissions and regulatory compliance status for 9000 point sources regulated by EPA.
- Atmospheric Sciences Modeling Division - part of NOAA's Air Resources Laboratory, contains atmospheric emission models.
- Envirofacts: national information system that provides an integrated single point of access to data on Superfund sites, drinking water, toxic and air releases, hazardous waste, water discharge permits, and grants.
- Toxic Release Inventory: reports by industry of release of more than 650 chemicals.
- Sector Facility Indexing Project: provides comprehensive information on the environmental performance of hundreds of facilities in five major industries.
- Surf Your Watershed: information on the "health" of aquatic resources in the US.
- Vehicle and Engine Emission Modeling Software: modeling software for use in testing vehicles and non-road engines for emissions.
Environmental Fate, Measurements, and Exposure
- Atmospheric Sciences Modeling Division - part of NOAA's Air Resources Laboratory, contains human exposure models.
- Center for Exposure Assessment Modeling: environmental simulation models.
- Center for Subsurface Modeling Support: provides a source for publicly available ground-water and vadose zone modeling software and services.
- Enhanced Stream Water Quality Model (QUAL2E): simulates the major reactions of nutrient cycles, algal production, benthic and carbonaceous demand, atmospheric reaeration and their effects on the dissolved oxygen balance.
- Environmental Monitoring and Assessment Program (EMAP): includes datasets of environmental monitoring of estuaries, surface waters, landscapes, and others
- Monitoring Water Quality: includes access to "STORET" database
- ROE Indicators: provides access to an outline of the draft document, EPA’s 2007 Report on the Environment: Technical Document (ROE-TD), where you can access 1) the 86 peer reviewed indicators that help answer 2) questions that are of critical importance to EPA's mission to protect human health and the environment.
- Wildlife Exposure Factors Handbook: data, references, and guidance for conducting exposure assessments for wildlife species exposed to toxic chemicals in their environment.
Health and Environmental Effects and Assessment
- Assessment Tools for the Evaluation of Risk (ASTER): Developed to assist regulators in performing ecological risk assessments by providing high quality data for discrete chemicals.
- Better Assessment Science Integrating Point and Nonpoint Sources (BASINS): integrates a geographic information system (GIS), national watershed data, and state-of-the-art environmental assessment and modeling tools into one convenient package.
- Integrated Risk Information System (IRIS): human health effects from chemical exposure.
Risk Management and Treatment Technology
- Envirofacts: national information system that provides an integrated single point of access to data on Superfund sites, drinking water, toxic and air releases, hazardous waste, water discharge permits, and grants.
- Technology Innovation Office - innovative technologies for characterization and remediation.
- Envirofacts Locational Information: Locational information supports data integration based on location, promoting the use of EPA's data resources for a wide array of cross-media analysis. The locational information in Envirofacts is stored in the Locational Reference Tables (LRT).
- Surf Your Watershed: locate, use, and share environmental information on your watershed or community.
