Here are the major data sources for wastewater surveillance data in the United States. We’ve included government sources and research/academic dashboards.
The page is split into two tables: national sources and state/local sources. Click on a row to see detailed annotations on that source.

National COVID-19 wastewater dashboards
Federal governmental and research efforts tracking COVID-19 through wastewater surveillance.| Name | Link | Metrics available | Update schedule | Notes | Annotations last updated |
|---|---|---|---|---|---|
| CDC National Wastewater Surveillance System | https://covid.cdc.gov/covid-data-tracker/#wastewater-surveillance | Percentage of sites within 5 categories of percent change in SARS-CoV-2 wastewater concentrations over time; current SARS-CoV-2 concentrations at each site relative to past data (0-100%); percent change at each site in the last 15 days; percent of wastwater samples with detectable virus; basic information about each site (type, state, county, population, first sampling date); normalized SARS-CoV-2 wastewater concentrations over time; data broken down by state and county | Thursdays by 8pm ET | Data from surveillance sites run by state and local health departments and voluntarily reported to the CDC, as well as from sites tested via the CDC's contract with Biobot, are all reported to this dashboard. Percentage of sites within each percent change category are displayed March 2022-present, but all other metrics are only shown for the past two weeks. Historical data can be accessed here: https://data.cdc.gov/Public-Health-Surveillance/NWSS-Public-SARS-CoV-2-Wastewater-Metric-Data/2ew6-ywp6 | 5/22/23 |
| Biobot Network | https://biobot.io/data/ | SARS-CoV-2 concentrations in wastewater over time, COVID-19 cases over time; data broken down by region and percents of variants | Mon and Thurs for wastewater data, Thurs only for variant data | Local data on this dashboard only includes sites in the free Biobot Network, not those that Biobot is testing via their contract with the CDC, unless they have opted to share it here as well. The national and regional trends include all Biobot sites (including those in the CDC contract). | 5/23/22 |
| COVIDPoops19 | https://ucmerced.maps.arcgis.com/apps/dashboards/index.html#/c778145ea5bb4daeb58d31afee389082 | Map of wastewater dashboards and testing sites around the world; links to sources for each one | As needed | Use this dashboard to find other wastewater dashboards! Includes both government and academic efforts, only reports testing sites where results are public. Testing sites are included even if monitoring has stopped as long as website is still active. | 5/23/22 |
| WastewaterSCAN (Sewer Coronavirus Alert Network) | https://data.wastewaterscan.org/ | Map of wastewater testing sites in the US; basic information about each site (location, population served); SARS-CoV-2 concentration in wastewater over time; viral load by variant; wastewater concentrations of MPX, Influenza A, influenza B, RSV, norovirus, HMPV over time | Varies by site | This academic project, based out of Stanford University, Emory University, and partners, has expanded from California to include wastewater testing sites in other states. It includes sites in 27 states as of April 2023. Basic info is also available at the Verily website: https://publichealth.verily.com/?utm_source=City+eNews&utm_campaign=4b527dbfee-2018-MLK-Holiday_COPY_01&utm_medium=email&utm_term=0_464f3a5a1d-4b527dbfee-127614057#Lawrence%2c%20KS:SARS-CoV-2 | 5/23/22 |
State data availability
As of May 28, 2023, 26 states maintain their own wastewater surveillance dashboards independently of the CDC NWSS site.
The COVID-19 Data Dispatch list also includes six local and seven regional dashboards.
