The ozone layer shields the Earth from harmful ultraviolet (UV) radiation. Ozone depletion, as well as seasonal and weather variations, cause different amounts of UV radiation to reach the Earth at any given time. The UV Index predicts the ultraviolet radiation levels on a 0-10+ scale, helping people determine appropriate sun-protective behaviors. More information on UV Index.

View greenhouse data in several geospatial and graphical formats for individual facilities or groups of facilities including direct emitters or suppliers. You can search the data set for facilities by name, or location or filter the data set by state or county, industrial sectors, annual facility emissions thresholds and greenhouse gases. More information on. More information Greenhouse Gas.

Information on air releases is contained in ICIS-AIR, a computer-based repository for information about air pollution in the United States. This information comes from source reports by various stationary sources of air pollution, such as electric power plants, steel mills, factories, and universities, and provides information about the air pollutants they produce. More information on ICIS-AIR.

The Hazardous Waste Report (Biennial Report) collects data on the generation, management, and minimization of hazardous waste. This provides detailed data on the generation of hazardous waste from large quantity generators and data on waste management practices from treatment, storage, and disposal facilities. The Biennial Report data provide a basis for trend analyses. Data about hazardous waste activities is reported for odd number years (beginning with 1989) to EPA. More information on BR.

Accidents, spills, leaks, and past improper disposal and handling of hazardous materials and wastes have resulted in tens of thousands of sites across our country that have contaminated our land, water (groundwater and surface water), and air (indoor and outdoor). These contaminated sites can threaten human health as well as the environment. More information on Brownfields-Cleanups.

Superfund is a program administered by the EPA to locate, investigate, and clean up the worst hazardous waste sites throughout the United States. Hazardous wastes were often left in the open, where they seeped into the ground, flowed into rivers and lakes, and contaminated soil and groundwater. Sites include abandoned warehouses, manufacturing facilities, processing plants, and landfills. More information on SEMS.

Hazardous waste information is contained in the Resource Conservation and Recovery Act Information (RCRAInfo), a national program management and inventory system about hazardous waste handlers. In general, all generators, transporters, treaters, storers, and disposers of hazardous waste are required to provide information about their activities to state environmental agencies. More information on RCRAInfo.

The Information Collection Rule (ICR) required water systems serving 100,000 people or more to collect samples and report on microbial (source water) and disinfection byproduct (treated water) levels for 18 months (July 1997-December 1998). Twelve months worth of these data is now stored in Envirofacts. Use the ICR Search Form to view reports at the water system, state, and national levels. More information on ICR.

The Permit Compliance System (PCS) and Integrated Compliance Information System (ICIS) provides information on companies which have been issued permits to discharge waste water into rivers. You can review information on when a permit was issued and expires, how much the company is permitted to discharge, and the actual monitoring data showing what the company has discharged. Many states have migrated to the new NPDES database, so the data for those states is static in EnviroFacts for those states. See the Full Search for a list of states. More information on PCS/ICIS.

The Safe Drinking Water Information System (SDWIS) contains information about public water systems and their violations of EPA's drinking water regulations. These statutes and accompanying regulations establish maximum contaminant levels, treatment techniques, and monitoring and reporting requirements to ensure that water provided to customers is safe for human consumption. More information on SDWIS.

Under the Pollution Prevention Act of 1990 (PPA), TRI collects information to track industry progress in reducing waste generation and moving towards safer waste management alternatives. When providing this information, many facilities choose to describe the measures they have taken to prevent pollution and reduce the amount of toxic chemicals entering the environment. As a result, TRI serves as a tool for identifying effective environmental practices and highlighting pollution prevention successes.More information on Pollution Prevention.

The Toxic Substances Control Act provides EPA with the authority to require reporting, record-keeping and testing requirements, and restrictions relating to chemical substances and/or mixtures. More information on TSCA.

The Toxics Release Inventory (TRI) Search allows access to basic facility information, all forms submitted to EPA since 1987, aggregate chemical release data for all years reported, and relative risk information from the Risk Screening Environmental Indicator (RSEI) tool. The results display any facility that has reported from 1987 to present, even though the facility may or may not have submitted TRI data in the most recent reporting year. The last year of data displayed represents the last year TRI data was reported. More information on TRI.

The Toxics Release Inventory (TRI) Explorer allows you generate reports on releases, transfers, and waste managed that can be displayed by facility, chemical, geographic area, industry (NAICS code), reporting years, or mapped. You may also generate State fact sheets. More information on TRI.

The Toxics Release Inventory (TRI) Form R Search allows access to facility release information as submitted for each chemical on a Form R to EPA. More information on TRI.

RadNet is a national network of more than 200 monitoring stations distributed across all 50 states and the American Territories. Each station regularly samples the nation's air, precipitation, or drinking water for a variety of radionuclides (e.g., iodine-131) and radiation types (e.g., gross beta (b)). More information on RadNet.

Facility Registry Service (FRS) is a centrally managed database that identifies facilities, sites or places subject to environmental regulations or of environmental interest. FRS creates high-quality, accurate, and authoritative facility identification records through rigorous verification and management procedures that incorporate information from program national systems, state master facility records, and data management personnel. More information on FRS.

EPA's management information system for grants programs is the Integrated Grants Management System (IGMS), which awards, administers, and monitors grants. Grants are regularly awarded to Federal, State, or local government agencies, universities, and other institutions that support EPA's environmental programs. More information on IGMS.

The Envirofacts Multisystem Search Form allows you to search multiple environmental databases for facility information, including toxic chemical releases, water discharge permit compliance, hazardous waste handling processes, Superfund status, and air emission estimates.
