With the pandemic surging across the country, more and more communities are keeping watch for the virus in wastewater. Yosemite National Park, once a safe haven from the coronavirus, recently found the virus in the park's raw sewage system. A working group is being set up among Northern California utilities to share sewage testing methods and results, coordinated by UC Berkeley's Berkeley Water Center. "Wastewater monitoring for SARS-CoV-2 is still in its infancy in the Bay Area," said Sasha Harris-Lovett, a scientist at the Berkeley Water Center. "But there is a lot of interest in pursuing it."
