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