The California Environmental Health Tracking Program (CEHTP) is a program within the California Department of Public Health and is funded by the Centers for Disease Control and Prevention. CEHTP is part of a larger initiative to establish Environmental Public Health Tracking systems at the national and state levels. Learn more about our program, past and current activities, the Tracking Implementation Advisory Group, and other program-related topics.

What does CEHTP do with data?

Environmental health surveillance systems can play a key role in reducing environmentally-related disease.  The ability to link health and environmental data can be crucial in understanding relationships between specific hazards and health outcomes.  However, environmental or health data by itself still plays an essential role in public health.  This data can help Californians to understand issues of community vulnerability, asset allocation, and prevention for many conditions about which environmental links are already known. In this spirit, CEHTP seeks to promote the utility and dissemination of health and environmental information.

Other resources

There are many agencies and organizations that provide information about topics related to environmental health and Tracking. We have compiled a list of resources, along with descriptions and links, that may be of interest.
