Environmental Data

In 2000, the Pew Environmental Health Commission determined that there is a lack of basic information needed to link environmental hazards and chronic diseases. In response, the CDC funded state health departments to begin to integrate health and environmental datasets by building the Environmental Public Health Tracking (EPHT) Network. This information may be used for quantifying the magnitude of a problem, detecting unusual trends and occurrences, identifying populations at risk, and facilitating environmental public health research.

Currently, this website provides the following information:

It is important to recognize that environmental measures do not provide information on the extent of exposure or the magnitude of the risk associated with exposure to environmental contaminants. The amount of exposure depends on:

  • the concentration of the contaminant in the environment
  • how much of the contaminant is taken in by the body
  • how long a person is exposed to the contamination

Other limitations associated with the use of air quality and water quality measures, particularly at the community level, are discussed on each environmental outcome page.
