Oregon Environmental Public Health Tracking
Environmental Public Health Tracking brings together environmental and health information sources.

Oregon Environmental Public Health Tracking (Oregon Tracking) is part of a national network working to increase understanding of environmental hazards, exposures, and health effects. Oregon Tracking hosts an indicator-based dynamic portal which provides easy to understand information at state, county, and sub-county levels for Oregon.

As a result, scientists, communities, policymakers, and the public are now better equipped to answer fundamental questions about the relationships between environmental exposures and health effects and can use this information to plan, apply, and evaluate public health actions to prevent and control environmentally related diseases.
