CDC’s One-Stop Shop for Environmental Public Health Data

Through its work in Environmental Public Health Tracking, CDC has realized that there is a need for a centralized Web site where people interested in environmental public health can readily access environmental or health data sets on the Internet.

This Web site provides a reference list of nationally funded data systems that have a relationship to environmental public health. This list is not meant to be a comprehensive inventory. Rather, it highlights the major data systems with a national scope where public health and environmental data can be directly downloaded from the Internet.

  • Acid Rain Emissions Tracking SystemExternal
    The overall goal of the Acid Rain Program is to achieve significant environmental and public health benefits through reductions in emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx), the primary causes of acid rain. Under the Acid Rain Program, each unit must continuously measure and record its emissions of S02, NOx, and CO2, as well as volumetric flow and opacity. In most cases, a continuous emission monitoring system must be used. There are provisions for initial equipment certification procedures, periodic quality assurance and quality control procedures, recordkeeping and reporting, and procedures for filling in missing data periods. Units report hourly emissions data to EPA on a quarterly basis. This data is then recorded in the Emissions Tracking System, which serves as a repository of emissions data for the utility industry.

  • Total Diet Study (TDS)External
    The TDS, sometimes called the Market Basket Study, is an ongoing FDA program that determines levels of various contaminants and nutrients in foods. Since its inception in 1961 as a program to monitor for radioactive contamination of foods following atmospheric nuclear testing, TDS has grown to encompass additional radionuclides, residues of pesticides, industrial chemicals, toxic and nutritional elements, and folate. In all instances, analyses have been performed on foods that are prepared as they would be consumed (table-ready), so the final results can be used to provide a realistic measure of the dietary intake of these analytes.

  • National Water Quality Assessment Program (NWQAP)ExternalThe NWQAP provides data about water chemistry, hydrology, land use, stream habitat, and aquatic life for major river basins and aquifers.
  • National Stream Quality Accounting Network (NASQAN)ExternalThe NASQAN program provides ongoing characterization of the concentrations and flux of sediment and chemicals in the Nation’s largest rivers.
  • National Atmospheric Deposition Program/National Trends Network (NADP/NTN)External
    The NADP/NTN is a nationwide network of precipitation monitoring sites. The network is a cooperative effort between many different groups, including the State Agricultural Experiment Stations, USGS, U.S. Department of Agriculture, and numerous other governmental and private entities. For a full list of contributors, see the collaborating agencies pageExternal . The NADP/NTN has grown from 22 stations at the end of 1978, its first year, to over 200 sitesExternal spanning the continental United States, Alaska, and Puerto Rico, and the Virgin Islands. The purpose of the network is to collect data on the chemistry of precipitation for monitoring of geographical and temporal long-term trends. The precipitation at each station is collected weekly according to strict clean-handling procedures. It is then sent to the Central Analytical Laboratory where it is analyzed for hydrogen (acidity as pH), sulfate, nitrate, ammonium, chloride, and base cations (such as calcium, magnesium, potassium and sodium).
  • National Water Information SystemExternal
    The USGS investigates the occurrence, quantity, quality, distribution, and movement of surface and underground waters and disseminates the data to the public, state and local governments, public and private utilities, and other federal agencies involved with managing our water resources. These pages provide access to water-resources data collected at approximately 1.5 million sites in all 50 states, the District of Columbia, and Puerto Rico.
  • National Geospatial Data ClearinghouseExternal
    The USGS node of the National Geospatial Data Clearinghouse is a component of the National Spatial Data Infrastructure. It provides a pathway to find information about geospatial or spatially referenced data available from USGS. The USGS node actually encompasses a distributed set of sites organized on the basis of the USGS’s four principal data themes. The first, Geography, offers the familiar USGS topographic maps and other geographic products that have long been associated with USGS. These products typically are of general use across many disciplines for basemaps and other purposes. As Geographic Information Systems have come to play an increasingly important role in science, however, the biology, geology, and water disciplines also have produced important geographic data sets related to their themes.

  • Behavioral Risk Factor Surveillance System (BRFSS)
    The BRFSS is a telephone survey conducted by all state health departments, the District of Columbia, Puerto Rico, the Virgin Islands, and Guam with assistance from CDC. The BRFSS is the largest continuously conducted telephone health survey in the world. States use BRFSS data to track critical health problems and to develop and evaluate public health programs. The BRFSS is the primary source of information on the health-related behaviors of adults in this country. States use standard procedures to collect data through monthly telephone interviews with adults 18 or older. BRFSS interviewers ask questions related to behaviors that are associated with preventable chronic diseases, injuries, and infectious diseases.
  • Cancer Control PlanetExternal
    This PLANET portal is sponsored by CDC, NCI and other agencies/organizations. The PLANET portal provides access to data and resources that can help planners, program staff, and researchers to design, implement and evaluate evidence-based cancer control programs. It also provides access to Web-based resources that can assist in:
    1. Assessing the cancer and/or risk factor burden within a given state.
    2. Identifying potential partner organizations that may already be working with high-risk populations.
    3. Understanding the current research findings and recommendations.
    4. Accessing and downloading evidence-based programs and products.
    5. Finding guidelines for planning and evaluation.
  • CDC Wonder
    WONDER provides a single point of access to a wide variety of reports and numeric public health data.
  • Data FERRET (Federal Electronic Research and Review Extraction Tool)
    FERRET allows access to micro-data sets via the Web. Currently, the 1994 Underlying Cause-of-Death File, the 1993 National Health Interview Survey and the third National Health and Nutrition Examination Survey are available via FERRET.
  • TheDataWebExternal
    TheDataWeb is a network of online data libraries. Topics include census data, economic data, health data, income and unemployment data, population data, labor data, cancer data, crime and transportation data, family dynamics, and vital statistics data.
  • Work Related Injury Statistics Query System (Work-RISQS)
    Work-RISQS provides a Web-based public access query system for obtaining national estimates (number of cases) and rates (number of cases per hours worked) for nonfatal occupational injuries and illnesses treated in U.S. hospital emergency departments. Users may interactively query based on demographic characteristics, nature of injury/illness, and incident circumstances for the years 1998 and 1999. Additional data-years will be added in future updates.
  • Web-Based Injury Statistics Query and Reporting System (WISQARS)
    WISQARS is the National Center for Injury Prevention and Control’s interactive, online database that provides customized injury-related mortality data and nonfatal injury data useful for research and for making informed public health decisions.
