The process involves adding skim milk to raw wastewater; through this concoction, researchers can isolate and detect viral RNA.

The environmental surveillance research was supported by the Population Health Initiative’s COVID-19 rapid response grants and holds the potential to serve as an early-warning system for COVID-19 detection.
