Explore wastewater data and dashboards for COVID-19 biomarkers.

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.

The California Department of Public Health (CDPH) aggregates confirmed cases of COVID-19 by sewershed restricted locations. Confirmed cases are defined as individuals with a positive molecular test, which tests for viral genetic material, such as a polymerase chain reaction test. Since wastewater data available starts from January 1st, 2021, rather than the beginning of the COVID-19 pandemic in 2020, the cumulative counts of the confirmed cases variable are shown as “NA”. Please note that values less than 5 for confirmed cases are masked (shown as “Masked”) if the sewershed population size is 50,000 or fewer, in accordance with de-identification guidelines. Values less than 3 for cases are masked (shown as “Masked”) if the sewershed population size is between 50,001 and 250,000. For no confirmed cases reported, values are set as zero.

The City of Bloomington Utilities (CBU) in cooperation with the Indiana Finance Authority is participating in a monitoring program which tests wastewater for coronavirus. From August through December of 2020, wastewater professionals from CBU collected samples three times each week at eight sites across Bloomington, including each of the two wastewater treatment plants. Throughout 2021 samples have been collected from the two wastewater treatment plants. Testing of those samples is conducted by multiple private, independent laboratories in an effort to gauge viral prevalence in the community. More information about this process can be found in the Indiana Wastewater Monitoring Report 2020 at: https://data.bloomington.in.gov/dataset/cd07435a-adae-4ba6-b671-2b711227131d/resource/22b67271-e2d4-4789-af7d-4fc7a586071c/download/indiana-wastewater-monitoring-report-2020_bclear.pdf
