In this photo provided by the University of Nevada, Reno, a research crew poses next to a manhole in Sparks, Nev., in December 2020, where they took samples for a study comparing wastewater concentrations of the virus that causes COVID-19 and trends in coronavirus cases in the community. Scientists say data sampled from sewers and wastewater treatment plants in the Reno-Sparks area last year showed a correlation to the number of positive tests for coronavirus that would follow in about seven days.
