Environmental Public Health Tracking

Adults and children enjoy playing outside.

Congratulations to our 2023-2024 mini-grantees!

The Wisconsin Tracking Program is pleased to award four Taking Action With Data mini-grants this year.

These projects will use Tracking data to make a difference in their community.

Congratulations to the City of West Allis, Taylor County, Green County, and Monroe County on their excellent new projects.


Wisconsin Environmental Public Health Tracking (EPHT) is your source for environmental health data in Wisconsin.

Access the data.


We house data on more than a dozen environmental public health topics such as air quality, asthma, Lyme disease, and many others.


We work with data managers to host the most up-to-date data available.


Our data portal has improved mapping, exporting, mobility. It can also display data below the county level. (Note that the portal works best with Firefox and Chrome web browsers.)

Interested in Tracking? Subscribe to our semiannual newsletter. You can learn more about us by reading our "Getting to Know Tracking" sheet, P-02446. (PDF)
