Wastewater data suggests COVID may not have peaked yet in 3 Bay Area spots – By Amy Graff (SFGate) / January 26, 2022
While multiple indicators suggest COVID-19 cases are on the decline across the San Francisco Bay Area, wastewater analyzed for SARS-CoV-2 in four counties by researchers at UC Berkeley’s Nelson Lab suggests that three areas of the region may have yet to peak.
Kara Nelson, a UC Berkeley professor of environmental engineering who helps manage the university’s wastewater monitoring program, said her team is keeping an eye on data at wastewater plants serving two areas of Contra Costa County: El Sobrante and San Pablo (West County plant) and Antioch, Martinez and Pittsburg (Delta Diablo plant). The team is also concerned about San Rafael’s Canal District (West Railroad plant).
While data at some of the other Bay Area wastewater treatment plants showed a downward trend, the most recent data from these three plants has suggested increasing concentrations of COVID, though Nelson said more data is needed to identify overall trends.
