The Wigginton-Eisenberg Laboratory works to provide wastewater testing data on multiple pathogens across south-east Michigan. The grid below provides an at-a-glance vision of the current state of wastewater levels. For more detailed information including graphs of this data over time, please visit each organism under the Pathogens tab. For more information about this system, you can click on the information icons ( ) throughout this dashboard or visit the About Page tab.

For the Current Detection Level Grid:

It is currently November. In the Fall season, pay particular attention to the levels of Influenza A, Norovirus, and RSV. SARS-CoV-2 causes disease throughout the year, though seasonal spikes have been identified in previous years during this time.

The buttons here will take you to the associated organism wastewater data under the Pathogen tab. If there are listed hyperlinks below the button, clicking on one of those will download a current level infographic for your use.

New to this page: The rolling average calculations no longer include values that are calculated as below the limit of quantification.

Testing for Influenza A


Regular Mpox testing in wastewater was paused on 10 September 2023. The laboratory maintains the ability to restart regular Mpox testing at any time, in order to support public health needs.

The Dashboard

This dashboard was created by Julie (Jules) Gilbert.


Wastewater-based epidemiology requires cooperation and coordination between many different groups and people, in order to best balance resources and data timeliness.
