History

2002-2005: Development

From 2002 to 2005, Congress provided funding to CDC for pilot projects. CDC began working with state and local health departments, federal partners, professional partners, and community groups to lay the foundation for a system to track environmental hazards and the health problems they may cause.

In fiscal year 2002, Congress provided CDC with initial funding to:

• begin developing a nationwide environmental public health tracking network
• develop capacity in environmental health within state and local health departments.

CDC’s goal was to develop a tracking system that integrates data about environmental hazards and exposures with data about diseases that are possibly linked to the environment. This system allows federal, state, and local agencies, and others to:

• monitor and distribute information about environmental hazards and disease trends
• advance research on possible linkages between environmental hazards and disease
• develop, implement, and evaluate regulatory and public health actions to prevent or control environment-related diseases.

Planning for an environmental public health tracking network was an important priority for CDC because of the opportunity it would provide to address some of the most challenging problems facing local, state, and national public health leaders. From the outset, this activity has involved substantial collaboration between CDC and public health and environmental partners. Read memoranda of understanding.

CDC assembled four workgroups to develop recommendations for the Environmental Public Health Tracking Program. The workgroups included representatives from 30 organizations, including the following:

• Federal agencies
• State and local public health and environment agencies
• Non-governmental organizations
• Academic institutions.

The workgroups addressed the following topics:

• Organization and management
• Data technology and tracking methodology
• Tracking system inventory and needs assessment
• Policy, and public health action.

See the Tracking Network Workgroups Report[PDF – 161 KB]for further details.

2006-2010: Implementation

The Tracking Program focused on launching national and state networks through building national infrastructure, workforce, and collaborations on data linkage.

Though the program began in 2002, the actual online Environmental Public Health Tracking Network launched in 2009. This dynamic, web-based system of data and information is helping draw a clear picture of the intricate relationships between environment and health.

Read Keeping Track, Promoting Health, which highlights the successes and challenges of the first four years of the Tracking Program.

2011-2015: Growth & Enhancement

This period was focused on expanding the Environmental Public Health Tracking Network by adding new data, functionality, states, and data-use activities and incorporating changes as a result of evaluation.

During this time, the Tracking Program celebrated its 10th anniversary. Check out A Decade of Tracking for highlights from the first 10 years.

  Biomonitoring is an essential component of the National Environmental Public Health Tracking Network. Tracking must include data on environmental hazards, human exposure, and health effects. The most health-relevant method of determining human exposure to environmental hazards is biomonitoring. Laboratory personnel bring new ideas and concepts to the Tracking Network.
