    COVID-19 Wastewater Detection - Historical

    Metadata Updated: March 29, 2025

    As described in https://data.cityofchicago.org/stories/s/sihu-d8va, the function of this dataset was replaced by https://data.cityofchicago.org/d/4tzt-ir6h. This dataset is historical-only.

    Concentrations of the SARS-CoV-2 virus (the COVID-19 virus) gene in the Chicago sewer system, as measured at eight sewershed sites. These sites represent catchment areas that describe wastewater from 319,700 Chicagoans as of January 2023.

    Because SARS-CoV-2 is shed in human feces, this method can be used to estimate changes in COVID-19 at different times and locations across Chicago. While the data in this dataset do not indicate how many people were infected with SARS-CoV-2, differences in the the normalized_n1 indicate whether the proportion of individuals at the site who are shedding that virus has changed.
