Innovative Wastewater Monitoring for COVID-19 Mitigation

Wisconsin State Laboratory of Hygiene Senior Scientist Martin Shafer published an article about Wisconsin’s COVID-19 wastewater surveillance program in Central States Water, the official magazine of the Central States Water Environment Association.

The wastewater surveillance program is a joint collaboration between the WSLH, the University of Wisconsin-Milwaukee School of Freshwater Sciences and the Wisconsin Department of Health Services. By routinely monitoring the amount of genetic material of SARS-CoV-2 present in wastewater, WSLH and UW-M scientists can determine whether, and to what extent, the SARS-CoV-2 virus (the virus causing COVID-19) is circulating within communities in Wisconsin.
