National Environmental Public Health Tracking Network

This United States Centers for Disease Control and Prevention (CDC) website allows the public to track environmental and public health information. The National Environmental Public Health Tracking Network is intended to be a dynamic Web-based tool for tracking and reporting environmental hazards and the health problems that may be related to them. The tracking network offers information on several environmental hazards and health conditions, such as asthma, cancer, and certain air and water contaminants. Local tracking networks report their data to the national network, allowing researchers and the public to monitor and identify trends in environmental public health data.
