In a mere five months, a modest, 1,200-square-foot "pop up" testing lab at the University of California, Berkeley, has been transformed into one of the country's only high-throughput facilities for measuring COVID-19 viruses in sewage water.  "When we test wastewater, we get information about a really large number of people with a very small number of samples, and we get information about asymptomatic infections," says Kara Nelson, who leads COVID-WEB and is a professor of civil and environmental engineering at UC Berkeley. For more on this, see our press release at Berkeley News.
