Wastewater tracking measures the concentration of SARS-CoV-2 in the City’s wastewater system. It supplements COVID surveillance by filling gaps in testing data created by lack of testing, asymptomatic cases, and lack of reporting for home tests. The City’s testing partner, Biobot Analytics, reports results weekly; you can see those reports below.
