Resources Data

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.

  • Survey of Occupational Injuries and Illnesses [external link]
    The Survey of Occupational Injuries and Illnesses is a Federal/State program in which employers' reports are collected annually from about 176,000 private industry establishments and processed by State agencies cooperating with the Bureau of Labor Statistics. Summary information on the number of injuries and illnesses is copied by these employers directly from their recordkeeping logs to the survey questionnaire. The questionnaire also asks for the number of employee hours worked (needed in the calculation of incidence rates) as well as its average employment (needed to verify the unit's employment-size class).

  • Beach Watch
    Under the BEACH program, a survey of state and local agencies that monitor water quality at beaches was conducted. The information received was compiled and is listed by beach on the Beach Watch Web site. Although the database includes a significant number of coastal and Great Lakes beaches, it does not include all U.S. beaches. Only the beaches whose monitoring officials responded to our survey are included. This survey will be conducted each year and as new information becomes available, it will be added to the Beach Watch Web site.
  • Watershed Assessment, Tracking & Environmental Results (WATERS)
    WATERS is an integrated information system for the nation's surface waters. The EPA Office of Water has various programs that store data in associated databases. These databases are separately managed with little coordination among them. Under WATERS, the program databases are connected to a larger framework.
  • STORET (short for STOrage and RETrieval)
    EPA maintains two data management systems containing water quality information for the nation's waters: the Legacy Data Center (LDC), and STORET. The LDC is a static, archived database and STORET is an operational system actively being populated with water-quality data. The LDC contains historical water-quality data dating back to the early part of the 20th century and collected up to the end of 1998. STORET contains data collected beginning in 1999, along with older data that has been properly documented and migrated from the LDC. Both systems contain raw biological, chemical, and physical data on surface and ground water collected by federal, state and local agencies, Indian Tribes, volunteer groups, academics, and others. All 50 states, territories, and jurisdictions of the U.S. are represented in these systems.

  • Total Diet Study (TDS)
    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 Oceanic and Atmospheric Administration (NOAA)

  • National Water Quality Assessment Program (NWQAP)

    The 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)

    The 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)
    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 page . The NADP/NTN has grown from 22 stations at the end of 1978, its first year, to over 200 sites 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 System
    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 Clearinghouse
    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 Planet
    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.
